All-Optical Control of Magnetization in Quantum-Confined Ultrathin Magnetic Metals
Saeedeh Mokarian Zanjani, Muhammad Tahir Naseem, Özgür Müstecaplıoğlu +1
All-optical control dynamics of magnetization in sub-10 nm metallic thin films are investigated, as these films with quantum confinement undergo unique interactions with femtosecon…
Ground-state cooling of mechanical resonators by quantum reservoir engineering
M. Tahir Naseem, Özgür E. Müstecaplıoğlu
We propose a scheme to cool down a mechanical resonator to its quantum ground-state, which is interacting with a working fluid via an optomechanical-like coupling. As opposed to st…
Minimal quantum heat manager boosted by bath spectral filtering
M. Tahir Naseem, Avijit Misra, Özgür E. Müstecaplıoğlu +1
We reveal the potentially important role of a general mechanism that has hitherto not been invoked in quantum heat management schemes, namely, spectral filtering of the coupling be…
Two-body quantum absorption refrigerators with optomechanical-like interactions
M. Tahir Naseem, Avijit Misra, Özgür E. Müstecaplıoğlu
Quantum absorption refrigerator (QAR) autonomously extracts heat from a cold bath and dumps into a hot bath by exploiting the input heat from a higher temperature reservoir. QARs t…
Quantum heat engine with a quadratically coupled optomechanical system
M. Tahir Naseem, Özgür E. Müstecaplıoğlu
We propose a quantum heat engine based on a quadratically coupled optomechanical system. The optical component of the system is driven periodically with an incoherent thermal drive…
Quantum Optical Two-Atom Thermal Diode
Cahit Kargi, M. Tahir Naseem, Tomáš Opatrný +2
We put forward a quantum-optical model for a thermal diode based on heat transfer between two thermal baths through a pair of interacting qubits. We find that if the qubits are cou…
