Unified trade-off optimization of quantum harmonic Otto engine and refrigerator
Varinder Singh, Satnam Singh, Obinna Abah +1
We investigate quantum Otto engine and refrigeration cycles of a time-dependent harmonic oscillator operating under the conditions of maximum -function, a trade-off objective fu…
Critical Quantum Metrology with Fully-Connected Models: From Heisenberg to Kibble-Zurek Scaling
Louis Garbe, Obinna Abah, Simone Felicetti +1
Phase transitions represent a compelling tool for classical and quantum sensing applications. It has been demonstrated that quantum sensors can in principle saturate the Heisenberg…
Harnessing non-adiabatic excitations promoted by a quantum critical point
Obinna Abah, Gabriele De Chiara, Mauro Paternostro +1
Crossing a quantum critical point in finite time challenges the adiabatic condition due to the closing of the energy gap, which ultimately results in the formation of excitations.…
