Periodically and quasiperiodically driven-anisotropic Dicke model
Pragna Das, Devendra Singh Bhakuni, Lea F. Santos +1
We analyze the anisotropic Dicke model in the presence of a periodic drive and under a quasiperiodic drive. The study of drive-induced phenomena in this experimentally accesible mo…
Phase transitions of the anisotropic Dicke model
Pragna Das, Devendra Singh Bhakuni, Auditya Sharma
We systematically analyze the various phase transitions of the anisotropic Dicke model that is endowed with both rotating and counter-rotating light-matter couplings. In addition t…
Fano Resonances in Quantum Transport with Vibrations
Ajith Ramachandran, Michael Genkin, Auditya Sharma +3
Quantum mechanical scattering involving continuum states coupled to a scatterer with a discrete spectrum gives rise to Fano resonances. Here we consider scatterers that possess int…
Persistent entanglement in a class of eigenstates of quantum Heisenberg spin glasses
Arun Kannawadi, Auditya Sharma, Arul Lakshminarayan
The eigenstates of a quantum spin glass Hamiltonian with long-range interaction are examined from the point of view of localisation and entanglement. In particular, low particle se…
The microscopic origin of thermodynamic entropy in isolated systems
J. M. Deutsch, Haibin Li, Auditya Sharma
A microscopic understanding of the thermodynamic entropy in quantum systems has been a mystery ever since the invention of quantum mechanics. In classical physics, this entropy is…
Entanglement, avoided crossings and quantum chaos in an Ising model with a tilted magnetic field
J. Karthik, Auditya Sharma, Arul Lakshminarayan
We study a one-dimensional Ising model with a magnetic field and show that tilting the field induces a transition to quantum chaos. We explore the stationary states of this Hamilto…
