Interrelated Thermalization and Quantum Criticality in a Lattice Gauge Simulator

Abstract: Gauge theory and thermalization are both foundations of physics and nowadays are both topics of essential importance for modern quantum science and technology [1][2][3][4][5][6][7][8][9][10]. Simulating lattice gauge theories (LGTs) realized recently with ultracold atoms provides a unique opportunity for carrying out a correlated study of gauge theory and thermalization in the same setting [11,12]. Theoretical studies have shown that an Ising quantum phase transition exists in this implemented LGT [13][14][15]… Show more

“…Thus, the |Z 2 state can only thermalize as one approaches the EPT, suggesting a connection between QMBS and criticality. This was also demonstrated experimentally in the Bose-Hubbard quantum simulator [52]. Moreover, by investigating the quantum Ising model in transverse and longitudinal fields, Ref.…”

“…Moreover, building blocks of matter-gauge interactions have been successfully demonstrated in cold atom settings, including both Z 2 [18] and U(1) [19] gauge theories in 1d, utilizing the quantum link formulation (QLM) of LGTs, where the dimension of the local Hilbert space of the gauge link is truncated and therefore finite. More recently, large-scale quantum simulations of Abelian LGTs have been reported in Rydberg atom arrays (Schwinger model [20,21], as well as a (2+1)-d Ising-Higgs gauge theory [22]) and with ultracold bosonic atoms in tilted optical superlattices [23][24][25]. In the continuum, quantum simulation of a topological gauge theory was realized in an optically-dressed Bose-Einstein condensate by realising a one-dimensional reduction of the Chern-Simons theory, the so-called chiral BF theory [26].…”

“…QLMs on the other hand are characterized by a finite-dimensional Hilbert space for the gauge degrees of freedom, offering the possibility of implementing matter and gauge degrees of freedom with a single atomic species. This has been demonstrated with ultracold bosons in tilted optical superlattice potentials [23][24][25] and a possible extension of this scheme to higher dimensions is currently explored theoretically [28]. Moreover, schemes based on Floquet engineering appear challenging due to the presence of higher-order terms that need to be suppressed in order to respect gauge invariance [18], for instance by implementations of additional stabilizers [29].…”

“…Several experimental works on the quantum simulation of lattice gauge theories have examined the Schwinger model, which is a discretised version of quantum electrodynamics in one dimension. The Schwinger model has been implemented in a number of quantum simulation platforms including trapped ion arrays [40,42,126], Rydberg atom arrays [19,127] and ultracold atoms in optical lattices [47,128,129]. Other works have demonstrated the engineering of gauge symmetries and present pathways to quantum simulation of lattice gauge theories once independent sites can be linked and sources of decoherence can be overcome.…”
