Trap-size scaling in confined particle systems at quantum transitions
Massimo Campostrini, Ettore Vicari
We develop a trap-size scaling theory for trapped particle systems at quantum transitions. As a theoretical laboratory, we consider a quantum XY chain in an external transverse fie…

Critical behavior and scaling in trapped systems
Massimo Campostrini, Ettore Vicari
We study the scaling properties of critical particle systems confined by a potential. Using renormalization-group arguments, we show that their critical behavior can be cast in the…
