Time delayed control of excited state quantum phase transitions in the Lipkin–Meshkov–Glick model
We theoretically investigate the role of dissipation in excited state quantum phase transitions (ESQPT) within the Lipkin–Meshkov–Glick model. Signatures of the ESQPT are directly visible in the complex spectrum of an effective Hamiltonian, whereas they get smeared out in the time-dependence of syst...
