# Simulating Quantum Mechanics with a $\theta$-term and an 't Hooft Anomaly on a Synthetic Dimension

@inproceedings{Shen2021SimulatingQM, title={Simulating Quantum Mechanics with a \$\theta\$-term and an 't Hooft Anomaly on a Synthetic Dimension}, author={Jiayu Shen and Di Luo and Chenxi Huang and Bryan K. Clark and Aida X. El-Khadra and Bryce Gadway and Patrick Draper}, year={2021} }

A topological θ-term in gauge theories, including quantum chromodynamics in 3+1 dimensions, gives rise to a sign problem that makes classical Monte Carlo simulations impractical. Quantum simulations are not subject to such sign problems and are a promising approach to studying these theories in the future. In the near term, it is interesting to study simpler models that retain some of the physical phenomena of interest and their implementation on quantum hardware. For example, dimensionally…

Digital Quantum Simulation of the Schwinger Model with Topological Term via Adiabatic State Preparation

- Physics
- 2020

We perform a digital quantum simulation of a gauge theory with a topological term in Minkowski spacetime, which is practically inaccessible by standard lattice Monte Carlo simulations. We focus on…

Global inconsistency, 't~Hooft anomaly, and level crossing in quantum mechanics

- Physics
- 2017

An 't Hooft anomaly is the obstruction for gauging symmetries, and it constrains possible low-energy behaviors of quantum field theories by excluding trivial infrared theories. Global inconsistency…

We perform digital quantum simulation to study screening and confinement in a gauge theory with a topological term, focusing on ($1+1$)-dimensional quantum electrodynamics (Schwinger model) with a…

Vacuum structure of Yang-Mills theory as a function of θ

- PhysicsJournal of High Energy Physics
- 2018

A bstractIt is believed that in SU(N) Yang-Mills theory observables are N -branched functions of the topological θ angle. This is supposed to be due to the existence of a set of locally-stable…

Second Chern number of a quantum-simulated non-Abelian Yang monopole

- Physics, MedicineScience

This work uses quantum simulation based on the spin degrees of freedom of atomic Bose-Einstein condensates to characterize a singularity present in five-dimensional non-Abelian gauge theories—a Yang monopole in terms of Chern numbers measured on enclosing manifolds.
