Gauge-Symmetry Violation Quantum Phase Transition in Lattice Gauge Theories
Maarten Van Damme, Jad C. Halimeh, Philipp Hauke
Gauge symmetry plays a key role in our description of subatomic matter. The vanishing photon mass, the long-ranged Coulomb law, and asymptotic freedom are all due to gauge invarian…
Local measures of dynamical quantum phase transitions
Jad C. Halimeh, Daniele Trapin, Maarten Van Damme +1
In recent years, dynamical quantum phase transitions (DQPTs) have emerged as a useful theoretical concept to characterize nonequilibrium states of quantum matter. DQPTs are marked…
Diffusive-to-ballistic crossover of symmetry violation in open many-body systems
Jad C. Halimeh, Philipp Hauke
Conservation laws in a quantum many-body system play a direct role in its dynamic behavior. Understanding the effect of weakly breaking a conservation law due to coherent and incoh…
Fate of Lattice Gauge Theories Under Decoherence
Jad C. Halimeh, Valentin Kasper, Philipp Hauke
A major test of the capabilities of modern quantum simulators and NISQ devices is the reliable realization of gauge theories, which constitute a gold standard of implementational e…
Gauge-Symmetry Protection Using Single-Body Terms
Jad C. Halimeh, Haifeng Lang, Julius Mildenberger +2
Quantum-simulator hardware promises new insights into problems from particle and nuclear physics. A major challenge is to reproduce gauge invariance, as violations of this quintess…
Quantum aging and dynamical universality in the long-range model
Jad C. Halimeh, Mohammad F. Maghrebi
Quantum quenches to or near criticality give rise to the phenomenon of \textit{aging}, manifested by glassy-like dynamics at short times and far from equilibrium. The recent surge…
Robustness of gauge-invariant dynamics against defects in ultracold-atom gauge theories
Jad C. Halimeh, Robert Ott, Ian P. McCulloch +2
Recent years have seen strong progress in quantum simulation of gauge-theory dynamics using ultracold-atom experiments. A principal challenge in these efforts is the certification…
Unconventional critical exponents at dynamical quantum phase transitions in a random Ising chain
Daniele Trapin, Jad C. Halimeh, Markus Heyl
Dynamical quantum phase transitions (DQPTs) feature singular temporal behavior in transient quantum states during nonequilibrium real-time evolution. In this work we show that DQPT…
Origin of staircase prethermalization in lattice gauge theories
Jad C. Halimeh, Philipp Hauke
Quantum many-body systems with exact local gauge symmetries exhibit rich out-of-equilibrium physics such as constrained dynamics and disorder-free localization. In a joint submissi…
Staircase Prethermalization and Constrained Dynamics in Lattice Gauge Theories
Jad C. Halimeh, Philipp Hauke
The dynamics of lattice gauge theories is characterized by an abundance of local symmetry constraints. Although errors that break gauge symmetry appear naturally in NISQ-era quantu…
Observation of gauge invariance in a 71-site Bose-Hubbard quantum simulator
Bing Yang, Hui Sun, Robert Ott +6
The modern description of elementary particles, as formulated in the Standard Model of particle physics, is built on gauge theories. Gauge theories implement fundamental laws of ph…
