Thermodynamic Cost of Regeneration in a Quantum Stirling Cycle
Ferdi Altintas
We study the standard four-stroke regenerative quantum Stirling heat engine cycle, which assumes local thermal equilibrium at each stage, within the standard weak-coupling, Markovi…
Quantum Coherence and non-Markovianity in a Noisy Quantum Tunneling Problem
Nisreen Mohammed Mahdi, Arzu Kurt, Ferdi Altintas
We investigate the coherence and non-Markovianity of a quantum tunneling system whose barrier is fluctuated by a telegraph noise, and its energy gap is modulated by Gaussian noise.…
Quantum Carnot cycle with inner friction
Selçuk Çakmak, Ferdi Altintas
A single driven spin is investigated as the working substance of a six-stroke irreversible quantum Carnot cycle. The role of inner friction associated with the finite-time adiabati…
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…
