WebThe overall phase of a system’s quantum state is an unmeasurable quantity that can be freely assigned. However, when the system is driven slowly in a cycle, it undergoes an adiabatic evolution which may bring its final state back to the initial one (1, 2); the accumulated phase then becomes gauge invariant and, therefore, detectable.As noted …

We study Nielsen complexity and Fubini-Study complexity for the transverse XY spin chain and establish their nonanalyticity at the critical lines. We obtain the scaling behavior of both complexities near quantum phase transitions in the thermodynamic limit, as a function of the system parameters. The scaling of the Nielsen …
WebIn this paper, we investigate the Ruppeiner thermodynamic geometry in the extended phase space of Reissner–Nordström (RN)-AdS black holes immersed in perfect fluid dark matter (PFDM) via P − V criticality. We first make a brief review on thermodynamics of this black hole, and further investigate the P − V criticality. We calculate the critical …
