Finite-Temperature Fidelity-Metric Approach to the Lipkin-Meshkov-Glick Model
D. D. Scherer, C. A. Müller, M. Kastner
The fidelity metric has recently been proposed as a useful and elegant approach to identify and characterize both quantum and classical phase transitions. We study this metric on t…
Kinetic energy and microcanonical nonanalyticities in finite and infinite systems
Lapo Casetti, Michael Kastner, Rachele Nerattini
In contrast to the canonical case, microcanonical thermodynamic functions can show nonanalyticities also for finite systems. In this paper we contribute to the understanding of the…
Microcanonical phase diagrams of short-range ferromagnets
Michael Kastner, Michel Pleimling
A phase diagram is a graph in parameter space showing the phase boundaries of a many-particle system. Commonly, the control parameters are chosen to be those of the (generalized) c…
