Thermodynamics of Coherence-Selective Quantum Reset Protocols
Jishad Kumar, Achilleas Lazarides, Tapio Ala-Nissila
We develop an exact theory of coherence-selective stroboscopic resetting for quadratic open quantum systems within the single-particle density-matrix formalism. We focus on the sur…

Coherence-Controlled Quantum Zeno Dynamics from Exact Reset Maps
Jishad Kumar, Achilleas Lazarides, Tapio Ala-Nissila
We develop an exact framework for quantum Zeno and anti-Zeno dynamics in a broad class of open systems, whose microscopic Hamiltonians are quadratic in bosonic or fermionic operato…

Interaction-Enabled Hartree Fixed Points in Fermionic Resetting Dynamics
Jishad Kumar, Achilleas Lazarides, Tapio Ala-Nissila
In resetting dynamics, a system is repeatedly coupled to and decoupled from ancillary degrees of freedom that are reinitialized between interactions. This provides a versatile rout…
