INTRODUCTION
Le rapp ort d activit e du Service de Physique Th eorique est etabli tous les deux ans Celui
ci r esume l activit e scienti que du SPhT durantlap erio de juin mai et servira de
do cumentdebasepourl evaluation du lab oratoire qui aura lieu a l automne
Pour la premi ere fois la partie scienti que de ce rapp ort est ecrite en anglais Il y a plusieurs
raisonsa cela D une part un nombre imp ortantdecoll egues etrangers pas tous francophones
particip ent a notre conseil scienti que ext erieur CSE D autre part ce rapp ort est aussi une
vitrine de nos activit es le fait qu il soit r edig e en anglais la langue de la ma jeure partie de
nos echanges scienti ques nous p ermet une plus grande di usion
L evaluation du lab oratoire a jusqu apr esent eu lieu durant un collo que de deux a trois
jours au cours duquel les physiciens du SPhT pr esentaient leurs travaux a leurs coll egues et
aux membres du CSE Ce collo que remplissait donc deux fonctions l une de communication
interne l autre d evaluation Pour satisfaire l ob jectif de communication interne le collo que
fut le plus souvent organis e loin du lab oratoire de fa con alib erer chacun de ses sollicitations
quotidiennes Mais l eloignementdeParis allonge le temps de d eplacemen t des membres du
CSE dont certains viennent de loin Nous avons donc choisi de d ecoupler a partir de cette
ann ee collo que interne et evaluation et de faire l evaluation dans le lab oratoire Les membres
du CSE p ourront ainsi rencontrer les physiciens sur leur lieu de travail et mieux p ercevoir les
multiples asp ects de la vie du lab oratoire Par ailleurs d egag es des contraintes de l evaluation
nous p ourrons lors du collo que que nous organiserons l an pro chain nous concentrer sur la
communication interne
Les e orts dans ce domaine essentiel p our un lab oratoire comme le SPhT sont sans cesse
a renouveler Rapp elons que l existence m eme d un gros lab oratoire de physique th eorique se
justi e par les p ossibilit es exceptionnelles ouvertes par la pluridiscipl in arit e de ses activit es
On p ourrait citera l appui de nombreux exemples de mobilit es th ematiques r eussies ou de
fertilisations crois ees entre domaines eloign es Mais la pluridiscipl i narit econtient aussi ses
dangers et l emiettement des activit es ou le manque de coh erence th ematique ont et e soulign es
a plusieurs reprises par notre CSE Les e orts de communication interne visent d ab ord a sensi
biliser chacun a l int er et des travaux de ses coll egues Le s eminaire du mardi cens e rassembler
tous les physiciens du lab oratoire y contribue et cette ann ee de nombreux coll egues ontpu
s y exprimer mais cela ne su t pas Tout en p oursuivant la plupart des actions entreprises
les ann ees pr ec edentes comme le journal du SPhT ou la journ ee des th eses ou les do ctorants
pr esentent au moins une fois par an leur travail a l ensemble du lab oratoire de nouvelles
formules ont et e essay ees Par exemple les matin ees th ematiques internes au SPhT ont et e
suivies et appr eci ees ilyenaeudeuxcetteann ee une en physique des particules une autre
vec la biophysique Au del ade pr esentant des activit es de physique th eorique al interface a
ces asp ects d echange d information nos e orts de communication interne visent egalementun
autre ob jectif Le contexte dans lequel nous d ecidons de nos recrutements a chang e nous y re
viendrons Pour que les choix que nous sommes amen es a faire conduisent aund evelopp ement
harmonieux du lab oratoire il est essentiel qu ils traduisent un certain consensus Ceci exige
d ebat confrontation d ob jectifs et de priorit es scienti ques parfois contradictoires Le conseil
scienti que du lab oratoire est le lieu naturel p our de tels d ebats Ils ont sans doute cette ann ee
et e facilit es par l exercice que s est imp os e le conseil scienti que en consacrant une journ eea
ecouter chacun de ses membres exp oser ses propres activit es et centres d int er et
Tous ces e orts seront p oursuivis Nous devrons aussi r e echir a la structure du lab oratoire
et aux cons equences du d ecoupage actuel en trois group es Ceux ci corresp ondent aux trois
grandes cat egories d activit es du lab oratoire ainsi qu elles sontpr esent ees dans le rapp ort et
auxquelles est asso ci eun voire deux s eminaire r egulier physique math ematique le lundi
matin et le vendredi matin physique statistique le lundi apr es midi physique nucl eaire des
particules et d astrophysique le mercredi apr es midi Certes ce d ecoupage en trois group es
d e ectifs comparables est commo de p our la gestion et garantit un minimum de discussions
collectives sur les invitations de visiteurs ou le choix des p ostdo cs Il est ind eniable qu il
es du lab oratoire comme dans intro duit une certaine coh erence dans la pr esentation des activit
ce rapp ort Mais il faut bien reconna tre que les group es ne jouent qu un r ole assez mo deste
sur le plan scienti que En fait la structure est un p eu lourde et ne favorise p eut etre pas
autant qu elle le devrait les initiatives en particulier celle des jeunes
Nos e orts internes s accompagnent d actions d ouverture vers l ensemble de la commu
naut e ainsi que vers la DSM Les journ ees Claude Itzykson sontdevenues une tradition du
lab oratoire Elles connaissent un grand succ es et ont rassembl e une b onne centaine de partici
pants l an pass e ainsi que cette ann ee Notons que cette ann ee ces journ ees etaient organis ees
conjointementavec le SPEC Le SPhT a accueilli p our des stages d un an des chercheurs du
CNRS D Bo os e C Monthus ainsi que deux p ostdo cs fran cais C Chandre G Misguich
Les cours du vendredi continuent a fonctionner avec succ es Cette ann ee deux de ces cours
ont et e accept es comme cours de l ecole do ctorale de la r egion parisienne Ces cours sont
r eguli erement suivis et contribuen tentre autre avaincre notre isolementg eographique ag
grav e parfois par les di cult es d acc es au lab oratoire li ees aux questions dites de s ecurit e
Avec la DSM des liens profonds existent et ce depuis longtemps Des membres du SPhT
particip ent aux conseils scienti ques de trois services du DAPNIA SPP SPhN et SAP Les
activit es du SPhT sont distribu ees sur cinq segments duCEA et acetitredesphysiciens du
SPhT particip ent aux r eunions de segment corresp ondantes Le SPhT co organise les rencontres
de la DSM a mis en place le conseil scienti que p our le calcul centralis e de la DSM que deux
de ses membres animent particip e au comit eder edaction de Phases Magazine Des collab
orations explicites existentavec le SPP et avec le SPEC Cela dit des liens scienti ques plus
forts p ourraient etre tiss es et on p eut avoir le sentimentquelesrichesses qui nous entourent
ne sont pas pleinement exploit ees
Le geste d ouverture le plus imp ortant de ces deux derni eres ann ees reste celui concer
nant nos recrutements sur p ostes CEA La d ecision d ouvrir ces p ostesa des jeunes form es
a l ext erieur du lab oratoire etait souhait ee par la DSM et fortement recommand ee par notre
conseil scienti que ext erieur M eme si elle a pu au d ebut etre ressentie assez durementpar
nos jeunes do ctorants et provo quer des discussions vives a l int erieur du lab oratoire elle etait
me semble t il indisp ensable et b eaucoup s accordent a en reconna tre aujourd hui le caract ere
p ositif Tout d ab ord m eme si ce n est pas le plus imp ortant il est b on de le souligner
le fait qu il existe des p ostes en physique th eorique au SPhT contribuea faire conna tre le
lab oratoire aux etudiants pr eparant une th ese ailleurs il nous p ermet aussi de rencontrer ces
etudiants et d appr ecier leurs travaux Mais surtout la diversit e des excellents candidats qui se
pr esentent sur nos p ostes nous p ermet de comp oser l avenir dans une p erio de de changements
profonds li es au renouvellement des p ersonnes qui prennent leur retraite ainsi qu al evolution
de certaines th ematiques traditionnelles du lab oratoire
Certes s etre donn e de plus grandes p ossibilit es de choix a rendu ces choix plus di ciles
Ceci nous a amen es a mettre en place une pro c edure rigoureuse et transparente qui a et e
appliqu ee p our les recrutements d ecid es en et ouverture de p oste examen des
candidatures par le conseil scienti que etablissement d une liste courte audition approfondie
des candidats de la liste courte Le pr esident du conseil scienti que ext erieur assiste ala
derni ere r eunion ou sont arr et ees les prop ositions de recrutement Bien qu aucune r egle n ait
et e etablie a ce sujet les d ecisions de recrutements se prennenttypiquement en premi ere ann ee
de p ostdo c A n que les choix e ectu es jouissent d un minimum de consensus le lab oratoire est
tr es largement consult e Remarquons p our nir que si les etudiants form es dans le lab oratoire
se trouventencomp etition avec tous les autres ils ne sont pas p our autantsyst ematiquement
ecart es ainsi que les derniers recrutements l ontmontr e
Il est b on aceniveau de faire quelques remarques concernant notre p olitique scienti que
Soulignons tout d ab ord que si l exigence sur l excellence scienti que des jeunes physiciens
que nous recrutons n a pas chang e il est ind eniable que le p oids des arguments li es au choix
de disciplines s est accru Ceci est li e au fait que les sujets dans lesquels nous recrutons ne se
limitent plus aux quelques sujets des th eses pr epar ees dans le lab oratoire ainsi qu aux profonds
changements th ematiques qui ont eu lieu dans le lab oratoire En particulier par suite de d eparts
a la retraite et d evolutions th ematiques de membres du SPhT certains sujets de recherche
sont en train de dispara tre compl etement Cela n est pas en soi dramatique et p eut re eter
l evolution naturelle de certaines discipline s Mais cela devient un sujet de pr eo ccupation si l on
remarque que les discipli nes touch ees sont celles qui concernent les activit es les plus concr etes
en particulier en physique nucl eaire et en physique des particules Si nous avons pu accueilli r
en th ese un etudiant travaillant sur des probl emes de structure nucl eaire l absence de David
Kosower en cong e depuis avril p our cr eation d entreprise va a ecter profond ement l activit e
en physique des particules Une r e exion se p oursuit sur ce qu il conviendra de faire p our ces
deux disciplines traditionnellement fortes au SPhT Je voudrais souligner ici que c est en partie
dans l esprit de renforcer des activit es en contact etroit avec les d evelopp ements exp erimentaux
que nous avons p oursuivi durant ces deux derni eres ann ees l e ort de recrutement en mati ere
condens ee Le d epart pr evu a la n de cette ann ee de Thierry Jolic ur nous invitera p eut etre a

niveau p ostdo c Pierre Vanhove l autre a plus haut niveau Michael Bershadsky Ce dernier
nous a quitt es p our prendre un p oste a l Universit edeToronto Il nous faudra sans doute
songer a le remplacer
Je voudrais maintenant ab order un autre sujet celui de nos relations avec le CNRS Rap
p elons que des liens forts unissent le SPhT et le CNRS les chercheurs du CNRS repr esentent
environ un tiers des chercheurs du SPhT l activit e du lab oratoire est examin ee r eguli erement

d etre reconnu comme une unit e CNRS Actuellement le lab oratoire est consid er e comme une

STATISTICAL PHYSICS
AND CONDENSED MATTER
A great variety of sub jects is gathered in this chapter devoted to Statistical Physics The
ma jority of the topics presented here b ene ted from the cross fertilization b etween di erent
metho ds originally develop ed in other branches of Physics integrable systems quantum eld
theory mathematical physics thanks to collab orations and discussions b etween memb ers
of our lab oratory having very di erent backgrounds Thus although the sub jects in whichwe
have b een interested may seem extremely diverse and sometimes rather mathematical their
unity stems from our desire to understand actual problems in Physics with the use of a handful
of techniques however sophisticated
This chapter is divided in four parts The rst section is devoted to general asp ects of
Statistical Physics we describ e various mo dels related to combinatorial problems graphs
folding of p olymers meanders to Brownian walks and to classical mo dels formulated on
random lattices Exact solutions of such mo dels are often obtained with the help of related
matrix mo dels a long standing sp eciality of our lab oratory More generally clever mappings
to related D Quantum gravity mo dels and the identi cation of a central charge haveallowed
to determine non trivial exp onents Time dep endent systems are treated in the rst section
from a traditional view p oint kinetic theory hydro dynamic instabilities turbulence The
techniques involved here are typical of applied analysis stability criteria mo de decomp osition
sho cks and sto chastic equations
This leads us naturally to the rst theme of section non equilibri um statistical physics
ailable The techniques Mo del solving plays again a crucial role since no general theory is yet av
used are b orrowed from traditional mathematical analysis one also needs algebraic tricks the
renormalisation group and numerical simulations to reveal and enco de the combinatorics of the
mo dels under investigation Systems out of equilibrium are related to disordered systems Path
integral metho ds are well suited to calculations concerning disordered systems e g they were
used to obtain an e ective description of a random medium when coupled to sup ersymmetry
techniques they provide an e cient to ol to describ e sup erconductors with impurities Among
disordered systems the study of spin glasses remains an active eld in the SPhT An essential
and outstanding question in spin glass theory is to discriminate b etween two mo dels the
droplet description and the Parisi replica symmetry breaking scheme Numerical simulations
and analysis of the uctuations around Parisi s mean eld solution conducted bymemb ers of
our group seem to favour replica theory
The third part of this chapter is devoted to Quantum systems Field theoretic metho ds
are p erfectly suited not only for mo deling correlated electrons and spin chains but also for
quantum uids such as Bose Einstein condensates D electron systems or sup erconductors
The reader will nd here a collection of techniques applied to concrete problems in condensed
matter large N expansion for the temp erature transition of a weakly interacting Bose gas
integrable mo dels and conformal eld theory for the Hall e ect Chern Simons action or duality
for calculating magnetization curves
In the last part of this chapter we describ e soft condensed matter and biological systems
Here again path integral representations are invaluable to describ e p olymers proteins and self
avoiding membranes Moreover space geometry and combinatorial top ology start now playing
a preeminent role p olyhedral tilings to understand sphere packings tensorial order parameters
to describ e conformational phase transitions secondary structures and folding mechanism of
proteins Coulombic systems suchaspolyelectrolytes are relevant b oth for industrial purp oses
and to understand biological uids For instance from variational descriptions of p olyelec
trolytes one calculates phase diagrams for the stabilityofavesicle in water that mayserveas
