Aspects of pseudoentropy in field theories [PDF]
Physical Review Research, 2021 In this paper, we explore properties of pseudoentropy in quantum field theories and spin systems from several approaches. pseudoentropy is a generalization of entanglement entropy such that it depends on both an initial and final state and has a clear ...

Towards the Construction of Wightman Functions of Integrable Quantum Field Theories [PDF]
, 2004 The purpose of the ``bootstrap program'' for integrable quantum field theories in 1+1 dimensions is to construct a model in terms of its Wightman functions explicitly.

Applications of Massive Integrable Quantum Field Theories to Problems in Condensed Matter Physics [PDF]
, 2004 We review applications of the sine-Gordon model, the O(3) non-linear sigma model, the U(1) Thirring model, and the O(N) Gross--Neveu model to quasi one-dimensional quantum magnets, Mott insulators, and carbon nanotubes. We focus upon the determination of

Interpretation of Quantum Field Theories with a Minimal Length Scale
, 2006 It has been proposed that the incorporation of an observer independent minimal length scale into the quantum field theories of the standard model effectively describes phenomenological aspects of quantum gravity.

Towards analog quantum simulations of lattice gauge theories with trapped ions [PDF]
Physical Review Research, 2020 Gauge field theories play a central role in modern physics and are at the heart of the Standard Model of elementary particles and interactions. Despite significant progress in applying classical computational techniques to simulate gauge theories, it has

Particle detectors from localized quantum field theories [PDF]
Physical Review D, 2023 We present a fully relativistic model for localized probes in quantum field theory. Furthermore, we show that it is possible to obtain particle detector models from localized quantum field theories that interact with a free quantum field.

Simulating Collider Physics on Quantum Computers Using Effective Field Theories. [PDF]
Physical Review Letters, 2021 Simulating the full dynamics of a quantum field theory over a wide range of energies requires exceptionally large quantum computing resources. Yet for many observables in particle physics, perturbative techniques are sufficient to accurately model all ...

Quantum phase transition dynamics in the two-dimensional transverse-field Ising model [PDF]
Science Advances, 2021 The quantum Kibble-Zurek mechanism (QKZM) predicts universal dynamical behavior near the quantum phase transitions (QPTs). It is now well understood for the one-dimensional quantum matter.

A study of quantum field theories in AdS at finite coupling [PDF]
Journal of High Energy Physics, 2018 A bstractWe study the O(N) and Gross-Neveu models at large N on AdSd+1 background. Thanks to the isometries of AdS, the observables in these theories are constrained by the SO(d, 2) conformal group even in the presence of mass deformations, as was ...

Homotopy theory of algebraic quantum field theories [PDF]
Letters in Mathematical Physics, 2018 Motivated by gauge theory, we develop a general framework for chain complex-valued algebraic quantum field theories. Building upon our recent operadic approach to this subject, we show that the category of such theories carries a canonical model ...
