Prethermal Floquet time crystals in chiral multiferroic chains and applications as quantum sensors of AC fields
Rohit Kumar Shukla, Levan Chotorlishvili, Sunil K. Mishra +1
We study the emergence of prethermal Floquet Time Crystal (pFTC) in disordered chiral multiferroic chains. The model is an extension of the usual periodically driven nearest-neighb…
Diagnosing chaos in a periodically driven Ising model with a ramping field via out-of-time-order correlation saturation
Rohit Kumar Shukla, Gaurav Rudra Malik, S. Aravinda +1
The dynamic region of out-of-time-ordered correlators (OTOCs) serves as a powerful indicator of chaos in classical and semiclassical systems, capturing the characteristic exponenti…
Generation of coherence in an exactly solvable nonlinear nanomechanical system
A. K. Singh, L. Chotorlishvili, S. Srivastava +4
This study is focused on the quantum dynamics of a nitrogen-vacancy (NV) center coupled to a nonlinear, periodically driven mechanical oscillator. For a continuous periodic driving…
Hybrid quantum-classical chaotic NEMS
A. K. Singh, L. Chotorlishvili, Z. Toklikishvili +2
We present an exactly solvable model of a hybrid quantum-classical system of a Nitrogen-Vacancy (NV) center spin (quantum spin) coupled to a nanocantilever (classical) and analyze…
Entanglement dynamics of two nitrogen vacancy centers coupled by a nanomechanical resonator
Z. Toklikishvili, L. Chotorlishvili, S. K. Mishra +4
In this paper we study the time evolution of the entanglement between two remote NV Centers (nitrogen vacancy in diamond) connected by a dual-mode nanomechanical resonator with mag…
Pulse and quench induced dynamical phase transition in a chiral multiferroic spin chain
M. Azimi, M. Sekania, S. K. Mishra +3
Quantum dynamics of magnetic order in a chiral multiferroic chain is studied. We consider two different scenarios: Ultrashort terahertz (THz) excitations or a sudden electric field…
Quantum Otto heat engine based on a multiferroic chain working substance
Maryam Azimi, Levan Chotorlishvili, Sunil K. Mishra +3
We study a quantum Otto engine operating on the basis of a helical spin- 1/2 multiferroic chain with strongly coupled magnetic and ferroelectric order parameters. The presence of a…
Beating the superparamagnetic size limit of nanoparticles on a ferroelectric substrate
A. Sukhov, L. Chotorlishvili, P. P. Horley +3
When decreasing the size of nanoscale magnetic particles their magnetization becomes vulnerable to thermal fluctuations as approaching the superparamgnetic limit, hindering thus ap…
