Photonic Analog Quantum Simulation of (1+1)-Dimensional Lattice Gauge Theory with Dynamical Matter
Nathan R. Gonzalez, Thea Budde, Klemen Kersic +5
We propose a photonic scheme for analog quantum simulation of a Lattice Gauge Theory (LGT) with dynamical matter based on the Jaynes-Cummings-Hubbard (JCH) model. Here, an a…
Hilbert Space Fragmentation and Gauge Symmetry
Thea Budde, Marina Kristć Marinković, Joao C. Pinto Barros
The Hamiltonian formulation of lattice gauge theories plays a central role in quantum simulations of gauge theories, and understanding their spectrum and other properties is expect…
Hilbert Space Fragmentation from Generalized Symmetries
Thea Budde, Marina Kristć Marinković, Joao C. Pinto Barros
Hilbert space fragmentation refers to exponential growth in the number of dynamically disconnected Krylov sectors with system size. It is taken as evidence of ergodicity breaking,…
Spectrum-Generating Algebra in Higher Dimensional Gauge Theories
Thea Budde, Jiangjing Dong, Marina Krstić Marinković +1
Non-equilibrium properties of strongly interacting gauge theories are often intractable with classical simulation methods. Due to recent developments of quantum simulations, studie…
Quantum Many-Body Scars for Arbitrary Integer Spin in 2+1D Abelian Gauge Theories
Thea Budde, Marina Krstić Marinković, Joao C. Pinto Barros
The existence of Quantum Many-Body Scars, which prevents thermalization from certain initial states after a long time, has been established across different quantum many-body syste…
Meron-Cluster Algorithms for Quantum Link Models
Joao C. Pinto Barros, Thea Budde, Marina Krstic Marinkovic
State-of-the-art algorithms for simulating fermions coupled to gauge fields often rely on integrating fermion degrees of freedom. While successful in simulating QCD at zero chemica…
