Thermalization dynamics of a gauge theory on a quantum simulator

发表刊物:Science

摘要:Gauge theories form the foundation of modern physics, with applications ranging from elementary particlephysics and early-universe cosmology to condensed matter systems. We perform quantum simulations of theunitary dynamics of a U(1) symmetric gauge field theory and demonstrate emergent irreversible behavior.The highly constrained gauge theory dynamics are encoded in a one-dimensional Bose-Hubbard simulator, whichcouples fermionic matter fields through dynamical gauge fields. We investigated global quantum quenchesand the equilibration to a steady state well approximated by a thermal ensemble. Our work may enable theinvestigation of elusive phenomena, such as Schwinger pair production and string breaking, and paves the wayfor simulating more complex, higher-dimensional gauge theories on quantum synthetic matter devices.
