It is for the first time that quantum simulation for high-energy physics (HEP) is studied in the
US decadal particle-physics community planning, and in fact until recently, this was not …

The topological θ-angle is central to several gauge theories in condensed-matter and high-
energy physics. For example, it is responsible for the strong CP problem in quantum …

Metastability stems from the finite lifetime of a state when a lower-energy configuration is
available but only by tunnelling through an energy barrier. It is observed in many natural …

In this work, we explore the interplay of confinement, string breaking and entanglement
asymmetry on a 1D quantum Ising chain. We consider the evolution of an initial domain wall …

Unconventional nonequilibrium phases with restricted correlation spreading and slow
entanglement growth have been proposed to emerge in systems with confined excitations …

Distinguishing whether a system supports alternate low-energy (locally stable) states—
stable (true vacuum) versus metastable (false vacuum)—by direct observation can be …

Confinement of topological excitations into particle-like states-typically associated with
theories of elementary particles-are known to occur in condensed matter systems, arising as …

Metastable states of quantum many-body systems with confinement offer a means to
simulate false vacuum phenomenology, including nonequilibrium dynamical processes like …

Ferromagnetism is an iconic example of a first-order phase transition taking place in
spatially extended systems and is characterized by hysteresis and the formation of domain …

Discrete time crystals represent a paradigmatic nonequilibrium phase of periodically driven
matter. Protecting its emergent spatiotemporal order necessitates a mechanism that hinders …
