Lattice Integrable Models of Quantum Field Theory [PDF]
, 1993 The quantum inverse scattering method allows one to put quantum field theory models on a lattice in a way which preservesthe dynamicalstructure.The trace identitiesare discussedfor thesemodels.

The quantum sine-Gordon model with quantum circuits
Nuclear Physics B, 2021 Analog quantum simulation has the potential to be an indispensable technique in the investigation of complex quantum systems. In this work, we numerically investigate a one-dimensional, faithful, analog, quantum electronic circuit simulator built out of ...

Tree-level correlations in the strong field regime
Journal of High Energy Physics, 2017 We consider the correlation function of an arbitrary number of local observables in quantum field theory, in situations where the field amplitude is large.

Geometric actions and flat space holography
Journal of High Energy Physics, 2020 In this paper we perform the Hamiltonian reduction of the action for three- dimensional Einstein gravity with vanishing cosmological constant using the Chern-Simons formulation and Bondi-van der Burg-Metzner-Sachs (BMS) boundary conditions. An equivalent

Entanglement and separability in continuum Rokhsar-Kivelson states
Physical Review Research, 2022 We study a vast family of continuum Rokhsar-Kivelson (RK) states, which have their ground state encoded by a local quantum field theory. These describe certain quantum magnets, and are also important in quantum information.

Parabolic Whittaker Functions and Topological Field Theories I
, 2010 First, we define a generalization of the standard quantum Toda chain inspired by a construction of quantum cohomology of partial flags spaces GL(\ell+1)/P, P a parabolic subgroup. Common eigenfunctions of the parabolic quantum Toda chains are generalized

Correlation functions of warped CFT
Journal of High Energy Physics, 2018 Warped conformal field theory (WCFT) is a two dimensional quantum field theory whose local symmetry algebra consists of a Virasoro algebra and a U(1) Kac-Moody algebra. In this paper, we study correlation functions for primary operators in WCFT.

FZZT branes and non-singlets of matrix quantum mechanics
Journal of High Energy Physics, 2020 We explore the non-singlet sector of matrix quantum mechanics dual to c = 1 Liouville theory. The non-singlets are obtained by adding N f × N bi-fundamental fields in the gauged matrix quantum mechanics model as well as a one dimensional Chern-Simons ...

Some exact results for the two-point function of an integrable quantum field theory
, 1981 The two point correlation function for the quantum nonlinear Schroedinger (delta-function gas) model is studied. An infinite series representation for this function is derived using the quantum inverse scattering formalism.

Dynamical Correlation Functions and Finite-size Scaling in Ruijsenaars-Schneider Model [PDF]
, 1996 The trigonometric Ruijsenaars-Schneider model is diagonalized by means of the Macdonald symmetric functions. We evaluate the dynamical density-density correlation function and the one-particle retarded Green function as well as their thermodynamic limit.
