nature of thermal relaxation after an instantaneous temperature quench. Combining tools …

Many-body dynamical phase transition in a quasiperiodic potential

R Modak, D Rakshit - Physical Review B, 2021 - APS
Much has been learned regarding dynamical quantum phase transition (DQPT) due to
sudden quenches across quantum critical points in traditional quantum systems. However …

Arrhenius law for interacting diffusive systems

V Kumar, A Pal, O Shpielberg - Physical Review E, 2024 - APS
Finding the mean time it takes for a particle to escape from a metastable state due to thermal
fluctuations is a fundamental problem in physics, chemistry, and biology. Here, we consider …

The full range of biopsychosocial complexity is mind-boggling, spanning a vast range of
spatiotemporal scales with complicated vertical, horizontal, and diagonal feedback …

Dynamical bulk-boundary correspondence and dynamical quantum phase transitions in higher-order topological insulators

T Masłowski, N Sedlmayr - Physical Review B, 2023 - APS
Dynamical quantum phase transitions occur in dynamically evolving quantum systems when
nonanalyticities occur at critical times in the return rate, a dynamical analog of the free …

Building continuous time crystals from rare events

Symmetry-breaking dynamical phase transitions (DPTs) abound in the fluctuations of
nonequilibrium systems. Here, we show that the spectral features of a particular class of …

Dynamical quantum phase transitions following double quenches: persistence of the initial state vs dynamical phases

H Cheraghi, N Sedlmayr - New Journal of Physics, 2023 - iopscience.iop.org
Dynamical quantum phase transitions (DQPTs) can occur following quenches in quantum
systems when the rate function, a dynamical analogue of the free energy, becomes non …

The continuum from temperament to mental illness: dynamical perspectives

W Sulis - Neuropsychobiology, 2021 - karger.com
Temperament in healthy individuals and mental illness have been conjectured to lie along a
continuum of neurobehavioral regulation. This continuum is frequently regarded in …
