On the classical limit and the problem of phase transitions

Michel V. Romerio, Walter Felipe Wreszinski

Published Jun 1, 1977• 2 citations
Publisher

Abstract

Some aspects of the relation between proofs of both absence and existence of phase transitions for a class of quantum spin systems and their classical counterparts are discussed. The results of absence of phase transitions apply to a large class of classical systems with special symmetry already considered by Vuillermot and Romerio (1975), and to their quantum mechanical analogues.

Quantum spin systems at finite temperature

Marek Biskup, Lincoln Chayes, Shannon L. Starr

ABSTRACT. We develop a novel approach to phase transitions in quantum spin models based on a relation to the corresponding classical spin systems. Explicitly, we show that whenever chessboard estimates can be used to prove a phase transition in the classical model, the corresponding quantum model will have a similar phase transition, provided the inverse temperature β and the magnitude of the quantum spins S satisfy β ≪ √ S. From the quantum system we require that it is reflection positive and that it has a meaningful classical limit; the core technical estimate may be described as an extension of the Berezin-Lieb inequalities down to the level of matrix elements. The general theory is further applied to prove phase transitions in various quantum spin systems with S ≫ 1. The most notable examples are the quantum orbital-compass model on Z 2 and the quantum 120degree model on Z 3 which are shown to exhibit symmetry breaking at low-temperatures despite

Phase transitions in the classical X-Y and some related models (invited)

David Paul Landau

Although classical spin systems in two dimensions cannot show usual long range order, they may exhibit unusual phase transitions of several different types. We present an overview of the work which has been done to understand both the statics and dynamics of these systems and offer some challenges for the future.

Viewpoint on the "Theory of the superglass phase" and a proof of principle of quantum critical jamming and related phases

Zohar Nussinov

A viewpoint article on the very interesting work of Biroli, Chamon, and Zamponi on superglasses. I further suggest how additional new superglass and "spin-superglass" phases of matter (the latter phases contain quenched disorder) and general characteristics may be proven as a theoretical proof of concept in various electronic systems. The new phases include: (1) superglasses of Cooper pairs, i.e., glassy superconductors, (2) superglass phases of quantum spins, and (3) superglasses of the electronic orbitals. New general features which may be derived by the same construct include (a) quantum dynamical heterogeneities- a low temperature quantum analogue of dynamical heterogeneities known to exist in classical glasses and spin-glasses wherein the local dynamics and temporal correlations are spatially non-uniform. I also discuss on a new class of quantum critical systems. In particular, I outline (b) the derivation of the quantum analogue of the zero temperature jamming transition that has a non-trivial dynamical exponent. We very briefly comment on (c) quantum liquid crystals.

Phase Transitions and Critical Phenomena in Quantum Systems

N. Boccara

Abstract From the point of view of phase transitions and critical phenomena quantum systems do not differ from classical systems. Such concepts as order parameters, self‐consistent approximations and critical exponents are reviewed for both types of systems and their similarities are stressed with the help of group theoretical considerations.

Quantum Proofs

Thomas Vidick, John Watrous

Quantum information and computation provide a fascinating twist on the notion of proofs in computational complexity theory. For instance, one may consider a quantum computational analogue of the complexity class NP, known as QMA, in which a quantum state plays the role of a proof (also called a certificate or witness), and is checked by a polynomial-time quantum computation. For some problems, the fact that a quantum proof state could be a superposition over exponentially many classical states appears to offer computational advantages over classical proof strings. In the interactive proof system setting, one may consider a verifier and one or more provers that exchange and process quantum information rather than classical information during an interaction for a given input string, giving rise to quantum complexity classes such as QIP, QSZK, and QMIP* that represent natural quantum analogues of IP, SZK, and MIP. While quantum interactive proof systems inherit some properties from their classical counterparts, they also possess distinct and uniquely quantum features that lead to an interesting landscape of complexity classes based on variants of this model. In this survey we provide an overview of many of the known results concerning quantum proofs, computational models based on this concept, and properties of the complexity classes they define. In particular, we discuss non-interactive proofs and the complexity class QMA, single-prover quantum interactive proof systems and the complexity class QIP, statistical zero-knowledge quantum interactive proof systems and the complexity class QSZK, and multiprover interactive proof systems and the complexity classes QMIP, QMIP*, and MIP*.
