Semiclassical excited-state signatures of quantum phase transitions in spin chains with variable-range interactions
Manuel Gessner, Victor Manuel Bastidas, Tobias Brandes +1
We study the excitation spectrum of a family of transverse-field spin chain models with variable interaction range and arbitrary spin , which in the case of interpolates…

Quantum signatures of Chimera states
V. M. Bastidas, I. Omelchenko, A. Zakharova +2
Chimera states are complex spatiotemporal patterns in networks of identical oscillators, characterized by the coexistence of synchronized and desynchronized dynamics. Here we propo…
