Time-reversal-based quantum metrology in a central-spin architecture: from SATIN to butterfly echo
Aditya Kumar, Sayan Choudhury
We investigate quantum-enhanced time-reversal-based metrology using the central spin model, in which a single ancilla spin of magnitude mediates interactions between…
Robust continuous symmetry breaking and multiversality in the chiral Dicke model
Nikolay Yegovtsev, Sayan Choudhury, W. Vincent Liu
The Dicke model (DM) serves as a paradigm for understanding collective light-matter interactions. We introduce the chiral Dicke model, a generalization where an atomic ensemble cou…
Heating suppression via two-rate random and quasiperiodic drive protocols
Krishanu Ghosh, Sayan Choudhury, Diptiman Sen +1
We study a random and quasiperiodically driven one-dimensional non-integrable PXP spin chain in a magnetic field for two distinct drive protocols. Each of these protocols involves…
Prethermalization in aperiodically driven classical spin systems
Sajag Kumar, Sayan Choudhury
Periodically driven classical many-body systems can host a rich zoo of prethermal dynamical phases. In this work, we extend the paradigm of classical prethermalization to aperiodic…
