Correlated Chern insulators in two-dimensional Raman lattices: A cold-atom regularization of strongly coupled four-Fermi field theories

open access: yesPhysical Review Research, 2022
We show that synthetic spin-orbit coupling for ultracold atoms in optical Raman potentials can be exploited to build versatile quantum simulators of correlated Chern insulators connected to strongly coupled four-Fermi field theories similar to the Gross ...

Conformal field theories are magical [PDF]

open access: yes, 2020
``Magic'' is the degree to which a state cannot be approximated by Clifford gates. We study mana, a measure of magic, in the ground state of the ${\mathbb{Z}}_{3}$ Potts model, and argue that it is a broadly useful diagnostic for many-body physics.

Lüscher-corrections for 1-particle form-factors in non-diagonally scattering integrable quantum field theories

open access: yesJournal of High Energy Physics, 2021
In this paper we derive from field theory a Lüscher-formula, which gives the leading exponentially small in volume corrections to the 1-particle form-factors in non-diagonally scattering integrable quantum field theories.

Quantum-Field-Theoretic Simulation Platform for Observing the Fate of the False Vacuum

open access: yesPRX Quantum, 2021
We design and implement a quantum annealing simulation platform to observe and study dynamical processes in quantum field theory (QFT). Our approach encodes the field theory as an Ising model, which is then solved by a quantum annealer.

Exact form factors in integrable quantum field theories: the sine-Gordon model [PDF]

open access: yes, 1998
We provide detailed arguments on how to derive properties of generalized form factors, originally proposed by one of the authors (M.K.) and Weisz twenty years ago, solely based on the assumption of "minimal analyticity" and the validity of the LSZ ...

From the Jaynes–Cummings model to non-abelian gauge theories: a guided tour for the quantum engineer

open access: yesNew Journal of Physics, 2020
The design of quantum many body systems, which have to fulfill an extensive number of constraints, appears as a formidable challenge within the field of quantum simulation.

Quantum simulation of chiral phase transitions

open access: yesJournal of High Energy Physics, 2022
The Nambu–Jona-Lasinio (NJL) model has been widely studied for investigating the chiral phase structure of strongly interacting matter. The study of the thermodynamics of field theories within the framework of Lattice Field Theory is limited by the sign ...

The quantum sine-Gordon model with quantum circuits

open access: yesNuclear 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 ...

Ghost-free infinite derivative quantum field theory [PDF]

open access: yesNuclear Physics B, 2018
In this paper we will study Lorentz-invariant, infinite derivative quantum field theories, where infinite derivatives give rise to non-local interactions at the energy scale M s , beyond the Standard Model. We will study a specific class, where there are

Quantum chromodynamics and other field theories on the light cone [PDF]

open access: yes, 1997
In recent years light-cone quantization of quantum field theory has emerged as a promising method for solving problems in the strong coupling regime.
