Critical quasienergy states in driven many-body systems
Victor Manuel Bastidas, Georg Engelhardt, Pedro Perez-Fernandez +2
We discuss singularities in the spectrum of driven many-body spin systems. In contrast to undriven models, the driving allows us to control the geometry of the quasienergy landscap…

Excited-state quantum phase transitions and periodic dynamics
G. Engelhardt, V. M. Bastidas, W. Kopylov +1
We investigate signatures of the excited-state quantum phase transition in the periodic dynamics of the Lipkin-Meshkov-Glick model and the Tavis-Cummings model. In the thermodynami…
