Hidden Quantum Criticality and Entanglement in Quench Dynamics
Sanku Paul, Paraj Titum, Mohammad F. Maghrebi
Entanglement exhibits universal behavior near the ground-state critical point where correlations are long-ranged and the thermodynamic entropy is vanishing. On the other hand, a qu…
Non-equilibrium criticality in quench dynamics of infinite-range spin models
Paraj Titum, Mohammad F. Maghrebi
Long-range interacting spin systems are ubiquitous in physics and exhibit a variety of ground state disorder-to-order phase transitions. We consider a prototype of infinite-range i…
Floquet engineering of optical lattices with spatial features and periodicity below the diffraction limit
S. Subhankar, P. Bienias, P. Titum +5
Floquet engineering or coherent time periodic driving of quantum systems has been successfully used to synthesize Hamiltonians with novel properties. In ultracold atomic systems, t…
Confined Quasiparticle Dynamics in Long-Range Interacting Quantum Spin Chains
Fangli Liu, Rex Lundgren, Paraj Titum +4
We study the quasiparticle excitation and quench dynamics of the one-dimensional transverse-field Ising model with power-law () interactions. We find that long-range interac…
Absence of Thermalization in Finite Isolated Interacting Floquet Systems
Karthik I. Seetharam, Paraj Titum, Michael Kolodrubetz +1
Conventional wisdom suggests that the long time behavior of isolated interacting periodically driven (Floquet) systems is a featureless maximal entropy state characterized by an in…
