Detecting quantum phase transitions in the quasi-stationary regime of Ising chains
Ceren B. Dağ, Philipp Uhrich, Yidan Wang +2
Recently, single-site observables have been shown to be useful for the detection of dynamical criticality due to an emergence of a universal critically-prethermal temporal regime i…

Probing dynamical criticality near quantum phase transitions
Ceren B. Dağ, Yidan Wang, Philipp Uhrich +2
We reveal a prethermal temporal regime upon suddenly quenching to the vicinity of a quantum phase transition in the time evolution of 1D spin chains. The prethermal regime is analy…

Universal scattering with general dispersion relations
Yidan Wang, Michael J. Gullans, Xuesen Na +2
Many synthetic quantum systems allow particles to have dispersion relations that are neither linear nor quadratic functions. Here, we explore single-particle scattering in general…
