Energy optimization of two-level quantum Otto machines
Satnam Singh, Obinna Abah
We present the spin quantum Otto machine under different optimization criterion when function either as a heat engine or a refrigerator. We examine the optimal performance of the h…
Measurement-based cooling of a nonlinear mechanical resonator
Ricardo Puebla, Obinna Abah, Mauro Paternostro
We propose two measurement-based schemes to cool a nonlinear mechanical resonator down to energies close to that of its ground state. The protocols rely on projective measurements…
Quantum state engineering by shortcuts-to-adiabaticity in interacting spin-boson systems
Obinna Abah, Ricardo Puebla, Mauro Paternostro
We present a fast and robust framework to prepare non-classical states of a bosonic mode exploiting a coherent exchange of excitations with a two-level system ruled by a Jaynes-Cum…
Shortcut-to-adiabaticity quantum Otto refrigerator
Obinna Abah, Mauro Paternostro, Eric Lutz
We investigate the performance of a quantum Otto refrigerator operating in finite time and exploiting local counterdiabatic techniques. We evaluate its coefficient of performance a…
Energetic cost of quantum control protocols
Obinna Abah, Ricardo Puebla, Anthony Kiely +3
We quantitatively assess the energetic cost of several well-known control protocols that achieve a finite time adiabatic dynamics, namely counterdiabatic and local counterdiabatic…
Implications of non-Markovian dynamics on information-driven engine
Obinna Abah, Mauro Paternostro
The understanding of memory effects arising from the interaction between system and environment is a key for engineering quantum thermodynamic devices beyond the standard Markovian…
