Exchange Fluctuation Theorems for Non-Markovian Baths in Quantum Collisional Model
Sayan Mondal, Sukrut Mondkar, Ujjwal Sen
The quantum exchange fluctuation theorem relates the probabilities of observing heat transfer along and against the temperature gradient between thermal baths at different temperat…
On prethermal time crystals from semi-holography
Toshali Mitra, Sukrut Mondkar, Ayan Mukhopadhyay +1
We demonstrate the existence of a pair of almost dissipationless oscillating modes at low temperatures in both the shear and sound channels of a hybrid quantum system, comprised of…
Violation of Universal Operator Growth Hypothesis in Conformal Field Theories
Dileep P. Jatkar, Sujoy Mahato, Sukrut Mondkar +1
We show that operator growth in large-central-charge conformal field theories with symmetry can violate the universal operator growth hypothesis once the Liouvillia…
Hall Viscosity in the Quark-Gluon Plasma
Sukrut Mondkar, Giorgio Torrieri, Matthias Kaminski +1
We study the Hall viscosity of the quark gluon plasma (QGP) created in non-central heavy-ion collisions. In the presence of a strong magnetic field or vorticity, rotational symmetr…
Bounds on Entanglement Dynamics from Krylov-Space Spreading
Swati Choudhary, Sukrut Mondkar, Ujjwal Sen
A recently developed notion, known as spread complexity, captures how a quantum state spreads in Krylov space under unitary evolution. Related Krylov-space approaches are increasin…
Dynamical Quantum Phase Transitions in Boundary Time Crystals
Sukrut Mondkar, Priya Ghosh, Ujjwal Sen
We demonstrate the existence of a dynamical quantum phase transition (DQPT) in a dissipative collective-spin model that exhibits the boundary time crystal (BTC) phase. We initializ…
