We present a theoretical study of quantum simulations of ($1+1$)-dimensional U(1) lattice gauge-Higgs models, which contain a compact U(1) gauge field and a Higgs matter field, by using ultracold bosonic gases on a one-dimensional optical lattice. Starting from the extended Bose-Hubbard model with on-site and nearest-neighbor interactions, we derive the U(1) lattice gauge-Higgs model as a low-energy effective theory. The derived gauge-Higgs model exhibits nontrivial phase transitions between… 
Glassy dynamics from quark confinement: Atomic quantum simulation of the gauge-Higgs model on a lattice
In the previous works, we proposed atomic quantum simulations of the U(1) gauge-Higgs model by ultracold Bose gases. By studying extended Bose-Hubbard models (EBHMs) including long-range repulsions,
Quantum Simulation of the Universal Features of the Polyakov Loop.
The Abelian Higgs model in 1+1 dimensions is shown to be a prime candidate for an experimental quantum simulation of a lattice gauge theory, and a discrete tensor reformulation is used to smoothly connect the space-time isotropic version used in most numerical lattice simulations to the continuous-time limit corresponding to the Hamiltonian formulation.
Towards analog quantum simulations of lattice gauge theories with trapped ions
Gauge field theories play a central role in modern physics and are at the heart of the Standard Model of elementary particles and interactions. Despite significant progress in applying classical
ZN gauge theories coupled to topological fermions: QED2 with a quantum mechanical θ angle
We present a detailed study of the topological Schwinger model [Phys. Rev. D 99, 014503 (2019)], which describes (1+1) quantum electrodynamics of an Abelian $U(1)$ gauge field coupled to a
Lattice Gauge Theories and String Dynamics in Rydberg Atom Quantum Simulators
Gauge theories are the cornerstone of our understanding of fundamental interactions among particles. Their properties are often probed in dynamical experiments, such as those performed at ion
Confinement and Lack of Thermalization after Quenches in the Bosonic Schwinger Model.
For the timescales able to simulate, the system evades thermalization and generates exotic asymptotic states that are made of two disjoint regions, an external deconfined region that seems to thermalize, and an inner core that reveals an area-law saturation of the entanglement entropy.
Lattice gauge theory and dynamical quantum phase transitions using noisy intermediate-scale quantum devices
With noisy intermediate scale quantum devices in mind, we propose a class of superconducting circuits for the general implementation of U(1) lattice gauge models via the formalism of quantum link
Floquet approach to ℤ2 lattice gauge theories with ultracold atoms in optical lattices
Quantum simulation has the potential to investigate gauge theories in strongly-interacting regimes, which are up to now inaccessible through conventional numerical techniques. Here, we take a first
Gauge-invariant quantum circuits for U (1) and Yang-Mills lattice gauge theories
Quantum computation represents an emerging framework to solve lattice gauge theories (LGT) with arbitrary gauge groups, a general and long-standing problem in computational physics. While quantum
Symmetry-protected topological phases in lattice gauge theories: Topological QED2
The interplay of symmetry, topology, and many-body effects in the classification of phases of matter poses a formidable challenge in condensed-matter physics. Such many-body effects are typically
