Entanglement and purification transitions in non-Hermitian quantum mechanics
Sarang Gopalakrishnan, Michael J. Gullans
A quantum system subject to continuous measurement and post-selection evolves according to a non-Hermitian Hamiltonian. We show that, as one increases the rate of post-selection, t…
Vectorial dark dissipative solitons in Kerr resonators
B. Kostet, S. S. Gopalakrishnan, E. Averlant +3
We report the existence of vectorial dark dissipative solitons in optical cavities subject to a coherently injected beam. We assume that the resonator is operating in a normal disp…
Superuniversality of superdiffusion
Enej Ilievski, Jacopo De Nardis, Sarang Gopalakrishnan +2
Anomalous finite-temperature transport has recently been observed in numerical studies of various integrable models in one dimension; these models share the feature of being invari…
Quantum criticality in the 2d quasiperiodic Potts model
Utkarsh Agrawal, Sarang Gopalakrishnan, Romain Vasseur
Quantum critical points in quasiperiodic magnets can realize new universality classes, with critical properties distinct from those of clean or disordered systems. Here, we study q…
Asymptotically exact theory for nonlinear spectroscopy of random quantum magnets
S. A. Parameswaran, Sarang Gopalakrishnan
We study nonlinear response in quantum spin systems {near infinite-randomness critical points}. Nonlinear dynamical probes, such as two-dimensional (2D) coherent spectroscopy, can…
Observation of a marginal Fermi glass using THz 2D coherent spectroscopy
Fahad Mahmood, Dipanjan Chaudhuri, Sarang Gopalakrishnan +2
A longstanding open problem in condensed matter physics is whether or not a strongly disordered interacting insulator can be mapped to a system of effectively non-interacting local…
