Emergence of a Renormalized Expansion in Quenched Critical Many-Body Systems
Benjamin Geiger, Juan Diego Urbina, Klaus Richter
We consider the fate of expansions in unstable many-body quantum systems, as realized by a quench across criticality, and show the emergence of as a renorma…

Classical, semiclassical and quantum signatures of quantum phase transitions in a (pseudo) relativistic many-body system
Maximilian Nitsch, Benjamin Geiger, Klaus Richter +1
We identify a (pseudo) relativistic spin-dependent analogue of the celebrated quantum phase transition driven by the formation of a bright soliton in attractive one-dimensional bos…
