A photonic Carnot engine powered by a quantum spin-star network
Deniz Türkpençe, Ferdi Altintas, Mauro Paternostro +1
We propose a spin-star network, where a central spin- is coupled with XXZ interaction to outer spin- particles, as a quantum fuel. If the network is in thermal equili…
Irreversible Work and Internal Friction in a Quantum Otto Cycle of a Single Arbitrary Spin
Selcuk Cakmak, Ferdi Altintas, Ozgur E. Mustecaplioglu
We propose an arbitrary driven spin as the working fluid of a quantum Otto cycle in the presence of internal friction. The role of total allocated time to the adiabatic branches of…
Irreversibility in a unitary finite-rate protocol: The concept of internal friction
Selcuk Cakmak, Ferdi Altintas, Ozgur E. Mustecaplioglu
The concept of internal friction, a fully quantum mechanical phenomena, is investigated in a simple, experimentally accessible quantum system in which a spin-1/2 is driven by a tra…
