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]
``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.

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
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]
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
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
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
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]
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]
In recent years light-cone quantization of quantum field theory has emerged as a promising method for solving problems in the strong coupling regime.
