text: "Persistent revivals recently observed in Rydberg atom simulators have challenged
our understanding of thermalization and attracted much interest to the concept
of quantum many-body scars (QMBSs). QMBSs are non-thermal highly excited eigenstates
that coexist with typical eigenstates in the spectrum of many-body Hamiltonians,
and have since been reported in multiple theoretical models, including the so-called
PXP model, approximately realized by Rydberg simulators. At the same time, questions
of how common QMBSs are and in what models they are physically realized remain
open. In this Letter, we demonstrate that QMBSs exist in a broader family of models
that includes and generalizes PXP to longer-range constraints and states with
different periodicity. We show that in each model, multiple QMBS families can
be found. Each of them relies on a different approximate \U0001D530\U0001D532(2)
algebra, leading to oscillatory dynamics in all cases. However, in contrast to
the PXP model, their observation requires launching dynamics from weakly entangled
initial states rather than from a product state. QMBSs reported here may be experimentally
probed using Rydberg atom simulator in the regime of longer-range Rydberg blockades."

text: Confinement is a prominent phenomenon in condensed matter and high-energy
physics that has recently become the focus of quantum-simulation experiments of
lattice gauge theories (LGTs). As such, a theoretical understanding of the effect
of confinement on LGT dynamics is not only of fundamental importance, but can
lend itself to upcoming experiments. Here, we show how confinement in a Z2 LGT
can be locally avoided by proximity to a resonance between the fermion mass and
the electric field strength. Furthermore, we show that this local deconfinement
can become global for certain initial conditions, where information transport
occurs over the entire chain. In addition, we show how this can lead to strong
quantum many-body scarring starting in different initial states. Our findings
provide deeper insights into the nature of confinement in Z2 LGTs and can be tested
on current and near-term quantum devices.

text: Mechanisms for suppressing thermalization in disorder-free many-body systems,
such as Hilbert space fragmentation and quantum many-body scars, have recently
attracted much interest in foundations of quantum statistical physics and potential
quantum information processing applications. However, their sensitivity to realistic
effects such as finite temperature remains largely unexplored. Here, we have utilized
IBM's Kolkata quantum processor to demonstrate an unexpected robustness of quantum
many-body scars at finite temperatures when the system is prepared in a thermal
Gibbs ensemble. We identify such robustness in the PXP model, which describes
quantum many-body scars in experimental systems of Rydberg atom arrays and ultracold
atoms in tilted Bose--Hubbard optical lattices. By contrast, other theoretical
models which host exact quantum many-body scars are found to lack such robustness,
and their scarring properties quickly decay with temperature. Our study sheds
light on the important differences between scarred models in terms of their algebraic
structures, which impacts their resilience to finite temperature.
