This article is published with open access at Springerlink.com Abstract. This is the first part of an oral history interview on the life- long involvement of Joel Lebowitz in the development of statistical mechanics. Here the covered topics include the formative years, which overlapped the tragic period of Nazi power and World War II in Eu- rope, the emigration to the United States in 1946 and the schooling there. It also includes the beginnings and early scientific works with Peter Bergmann, Oliver Penrose and many others. The second part will appear in a forthcoming issue of Eur. Phys. J.

I was born in Taceva, a small town in the Carpathian mountains, in an area which was at that time part of Czechoslovakia, on the border of Romania and about a hundred kilometers from Poland. That was in 1930, and the town then had a population of about ten thousand people, a small town, but fairly advanced.

Put differently, the question was what happens when the world of interacting particle systems is put together with the world of disordered media. This area of research is lively and thriving, with a constant flow of new ideas and exciting developments, in the best of the tradition of mathematical physics. Spin glasses were at the core of the program, but in a broad sense. Spin glass theory has found ap- plications in a wide range of areas, including information theory, coding theory, algorithmics, complexity, random networks, population genetics, epidemiology and finance. This opens up many new challenges to mathematics. 2 Recent Developments and Open Problems The workshop brought together researchers whose interest lies at the intersection of disordered statistical mechanics and random graph theory, with a clear emphasis on applications. The multidisciplinary nature of the proposed topics has attracted research groups with different backgrounds and thus provided exchange of ideas with cross-fertilisation. As an example, we mention two problems on which we focused during the workshop. The first problem has its origin in the many fundamental issues that are still open in the theory of spin glasses. Even tough today we have a rigorous proof, in the context of mean-field models, of the solution for the free energy first proposed by G.

  • A Mathematical Physicist's Perspective on Statistical Mechanics
    A mathematical physicist’s perspective on Statistical Mechanics Michael Aizenman Princeton University André Aisenstadt Lecture (I) CRM, Montreal Sept. 24, 2018 1 /14 Statistical mechanics explains and quantifies the process by which structure emerges from chaos. Its genesis is in Boltzmann’s explanation of thermodynamical behavior and in particular of the concept of entropy. The statistic mechanical perspective was instrumental for Planck’s theory of the light quantization and Einstein’s calculation of the Avogadro number. More recent developments include links between the physics of critical phenomena and the mathematics of conformally invariant random structures, stochastic integrability, and representation theory. The talk will focus on examples of observations and conjectures which turned out to point in fruitful directions. 2 /14 Statistical Mechanics: laws emerging from chaos Laws expressed in equations F = ma, E = mc2, PV = nRT .

  • On Spin Systems with Quenched Randomness: Classical and Quantum
    On Spin Systems with Quenched Randomness: Classical and Quantum Rafael L. Greenblatt(a) ∗ Michael Aizenman(b) y Joel L. Lebowitz(c)∗ (a) Department of Physics and Astronomy Rutgers University, Piscataway NJ 08854-8019, USA (b) Departments of Physics and Mathematics Princeton University, Princeton NJ 08544, USA (a) Departments of Mathematics and Physics Rutgers University, Piscataway NJ 08854-8019, USA December 5, 2009 Dedicated to Nihat Berker on the occasion of his 60th birthday Abstract The rounding of first order phase transitions by quenched randomness is stated in a form which is applicable to both classical and quantum systems: The free energy, as well as the ground state energy, of a spin system on a d-dimensional lattice is continuously differentiable with respect to any parameter in the Hamiltonian to which some randomness has been added when d ≤ 2. This implies absence of jumps in the associated order parameter, e.g., the magnetization in case of a random magnetic field. A similar result applies in cases of continuous symmetry breaking for d ≤ 4. Some questions concerning the behavior of related order parameters in such random systems are discussed. 1 Introduction The effect of quenched randomness on the equilibrium and transport properties of macroscopic systems is a subject of great theoretical and practical interest which is close to Nihat’s heart. He and his collaborators [1, 2, 3] made important contributions to the study of the changes brought about by such randomness in phase transitions occurring in the pure (non-random) system. These effects can be profound in low dimensions. Their understanding evolved in a somewhat interesting way.

    Proof of Rounding by Quenched Disorder of First Order Transitions in Low-Dimensional Quantum Systems Michael Aizenman∗ Departments of Physics and Mathematics, Princeton University, Princeton NJ 08544-8019 Rafael L. Greenblatt† Dipartamento di Matematica, Universit`adegli Studi Roma Tre, Largo San Leonardo Murialdo 1, 00146 Roma, Italy Joel L. Lebowitz‡ Departments of Mathematics and Physics, Rutgers University, Piscataway NJ 08854-8019 (Dated: November 23, 2011) Abstract We prove that for quantum lattice systems in d ≤ 2 dimensions the addition of quenched disorder rounds any first order phase transition in the corresponding conjugate order parameter, both at positive temperatures and at T = 0. For systems with continuous symmetry the statement extends up to d ≤ 4 dimensions. This establishes for quantum systems the existence of the Imry-Ma phenomenon which for classical systems was proven by Aizenman and Wehr. The extension of the proof to quantum systems is achieved by carrying out the analysis at the level of thermodynamic quantities rather than equilibrium states.

INTRODUCTION Quenched disorder is known to have a pronounced effect on phase transitions in low dimensional systems. As Imry and Ma pointed out in 1975 [1], disorder can prevent the appearance of discontinuities, and of long range order, associated with first order transitions. Nonetheless, for a number of years there was considerable uncertainty about the mechanisms involved in such a “rounding effect”, and consequently also of the circumstances in which this effect appears [2].

  • The Ising Model in Three and Four Dimensions
    Scientific project: The Ising Model in three and four dimensions Michael Aizenman Hugo Duminil-Copin Princeton University University of Geneva Goal of the proposal The proposed collaboration will connect a leading young researcher, of outstanding promise in his cohort, with an established au- thority in the field. Thematically, the collaboration would link Modern Proba- bility with related Mathematical Physics from which many of its deep challenges originate. It is expected to also form a basis for a network which has room for growth, seeding a collaboration on which a future European Research Council (ERC) grant application (by Hugo Duminil-Copin) may be based for a collabo- rative program which may grow to involve students and other young researchers, and possibly also other institutions. Princeton and Geneva Universities possess exceptionally strong groups in the respective fields and the collaboration be- tween the two principal investigators could extend to other members of these two research groups in order to tackle related problems. Scientific motivation Since its formulation by Lenz [Len20], the Ising model has been the most studied example of a system undergoing a phase transition. The model was intended to explain the fact, discovered by Pierre Curie in 1895, that a ferromagnet loses its magnetization when heated above a critical temper- ature. Beyond its original motivation, the Ising model and its phase transition were found to be of a rather broad relevance, though of course its features do not exhaust the range of possible behaviors in statistical mechanics. The model also provided the testing ground for a large variety of techniques which have been later used to study other models.
