Dynamical phase transitions at finite temperature from fidelity and interferometric Loschmidt echo induced metrics
Bruno Mera, Chrysoula Vlachou, Nikola Paunković +2
We study finite-temperature Dynamical Quantum Phase Transitions (DQPTs) by means of the fidelity and the interferometric Loschmidt Echo (LE) induced metrics. We analyse the associa…

Spinor Description of a General Spin-J System
V. R. Vieira, P. D. Sacramento
We consider a spin coherent states description of a general quantum spin system. It is shown that it is possible to use the spin-1/2 representation to study the general spin-J case…
