Measurement-induced continuous time crystals

M Krishna, P Solanki, M Hajdušek, S Vinjanampathy - Physical Review Letters, 2023 - APS
Strong measurements usually restrict the dynamics of measured finite dimensional systems
to the Zeno subspace, where subsequent evolution is unitary due to the suppression of …

Dynamical l-bits and persistent oscillations in Stark many-body localization

TM Gunawardana, B Buča - Physical Review B, 2022 - APS
Stark many-body localized (SMBL) systems have been shown both numerically and
experimentally to have Bloch many-body oscillations, quantum many-body scars, and …

Select Topics in Open Quantum Systems

M Krishna, P Solanki, S Vinjanampathy - Journal of the Indian Institute of …, 2023 - Springer
The design of realistic quantum technologies relies intricately on the understanding of open
quantum systems. Such open systems are often studied as an input–output theory, where …

Cooperation and competition in synchronous open quantum systems

T Murtadho, S Vinjanampathy, J Thingna - Physical Review Letters, 2023 - APS
Synchronization between limit cycle oscillators can arise through entrainment to an external
drive or through mutual coupling. The interplay between the two mechanisms has been …

Quantum nonstationary phenomena of spin systems in collision models

Y Li, X Li, J ** - Physical Review A, 2023 - APS
We investigate the nonstationary phenomenon in a tripartite spin-1/2 system in the collision
model (CM) framework. After introducing the dissipation through the system-environment …

Observation of quantum phase synchronization in a nuclear-spin system

VR Krithika, P Solanki, S Vinjanampathy, TS Mahesh - Physical Review A, 2022 - APS
We report an experimental study of phase synchronization in a pair of interacting nuclear

Exact multistability and dissipative time crystals in interacting fermionic lattices

H Alaeian, B Buča - Communications Physics, 2022 - nature.com
The existence of multistability in quantum systems beyond the mean-field approximation
remains an intensely debated open question. Quantum fluctuations are finite-size …

Synchronization by magnetostriction

J Cheng, W Li, J Li - Physical Review Research, 2023 - APS
We show how to utilize magnetostriction to synchronize two mechanical vibration modes in a
cavity magnomechanical (CMM) system. The dispersive magnetostrictive interaction …

Macroscopic quantum synchronization effects

T Nadolny, C Bruder - Physical Review Letters, 2023 - APS
We theoretically describe macroscopic quantum synchronization effects occurring in a
network of all-to-all coupled quantum limit-cycle oscillators. The coupling causes a transition …

Deriving lower bounds on the efficiency of near-degenerate thermal machines via synchronization
