Nucleon Resonances and Quark Structure
Nucleon Resonances and Quark Structure J.T. Londergan Physics Dept and Nuclear Theory Center, Indiana University, Bloomington, IN 47405, USA. [email protected] (Dated: October 25, 2018) A pedagogical review of the past 50 years of study of resonances, leading to our understanding of the quark content of baryons and mesons. The level of this review is intended for undergraduates or first-year graduate students. Topics covered include: the quark structure of the proton as revealed through deep inelastic scattering; structure functions and what they reveal about proton structure; and prospects for further studies with new and upgraded facilities, particularly a proposed electron- ion collider. Keywords: I. INTRODUCTION These lectures were given at Aligarh Muslim University, Aligarh India, at a nuclear physics workshop attended by Indian graduate students and postdocs. These lectures provide a pedagogical review of the past 50 years of experimental and theoretical studies of the quark and gluon structure of the nucleon. Since many speakers at this workshop will discuss structure functions extracted from deep inelastic scattering reactions, we define these quantities and review what can be extracted from them. We hope that specialists in this field will tolerate our brief and superficial summary of many years' study of strongly-interacting systems. FIG. 1: Richard H. Dalitz, 1925-2006. arXiv:0907.3431v1 [hep-ph] 20 Jul 2009 These lectures are dedicated to my mentor, Richard Dalitz, who was from 1963-2000 Royal Society Professor of Physics at Oxford University and who made seminal contributions in particle phenomenology. Dalitz pairs (electron- positron pairs from decay of a high-energy photon) and the Dalitz plot were named after him. -
Solid State Physics 2 Lecture 4: Magnetism in Charge Insulators
Physics 7450: Solid State Physics 2 Lecture 4: Magnetism in charge insulators Leo Radzihovsky (Dated: 19 February, 2015) Abstract In these lectures, we will study magnetism in insulators. After a warm up with paramagnetism of independent spins, we will discuss the spin exchange interactions in solids, arising from the combination of Coulomb repulsion and Pauli exclusion, and leads to the Heisenberg model of magnetism. Focussing on the simplest ferromagnetic and antiferromagnetic states, we will analyze thermodynamics and correlations of low-energy excitations around these states using Holstein- Primakoff and Schwinger bosons descriptions. We will use Jordan-Wigner transformation to solve a one-dimensional spin-1/2 chain. We will discuss coherent-spin states path-integral formulation of magnetism emphasizing, the role of Berry’s phase and will analyze phase transitions using Landau’s mean-field theory of FM and AFM phases. 1 I. INTRODUCTION A. Outline • Paramagnetism • Spin exchange vs dipolar interaction • Heisenberg model and crystalline anisotropies • Hostein-Primakoff and Schwinger bosons • Jordan-Wigner transformation and XXZ chain • Coherent-spin states and Berry phases • Mean-field and Landau theory of FM and AFM states B. Background In these notes we will explore some of aspects of magnetism in charge insulators. Mag- netism is a formation and response of magnetic moments to external magnetic field H and their interaction. In general there are two sources of magnetic moment and associated mag- netization density M. One is quite intuitive, due to orbital charge current j in the material 1 Z M = r × j, 2 r much like current wire loop produces magnetic field. -

Title: the Distribution of an Illustrated Timeline Wall Chart and Teacher's Guide of 20Fh Century Physics
REPORT NSF GRANT #PHY-98143318 Title: The Distribution of an Illustrated Timeline Wall Chart and Teacher’s Guide of 20fhCentury Physics DOE Patent Clearance Granted December 26,2000 Principal Investigator, Brian Schwartz, The American Physical Society 1 Physics Ellipse College Park, MD 20740 301-209-3223 [email protected] BACKGROUND The American Physi a1 Society s part of its centennial celebration in March of 1999 decided to develop a timeline wall chart on the history of 20thcentury physics. This resulted in eleven consecutive posters, which when mounted side by side, create a %foot mural. The timeline exhibits and describes the millstones of physics in images and words. The timeline functions as a chronology, a work of art, a permanent open textbook, and a gigantic photo album covering a hundred years in the life of the community of physicists and the existence of the American Physical Society . Each of the eleven posters begins with a brief essay that places a major scientific achievement of the decade in its historical context. Large portraits of the essays’ subjects include youthful photographs of Marie Curie, Albert Einstein, and Richard Feynman among others, to help put a face on science. Below the essays, a total of over 130 individual discoveries and inventions, explained in dated text boxes with accompanying images, form the backbone of the timeline. For ease of comprehension, this wealth of material is organized into five color- coded story lines the stretch horizontally across the hundred years of the 20th century. The five story lines are: Cosmic Scale, relate the story of astrophysics and cosmology; Human Scale, refers to the physics of the more familiar distances from the global to the microscopic; Atomic Scale, focuses on the submicroscopic This report was prepared as an account of work sponsored by an agency of the United States Government. -
