Irreversibility in a unitary finite-rate protocol: the concept of internal friction
Cakmak, Selcuk; Altintas, Ferdi; Mustecaplioglu, Ozgur E. (Iop Publishing Ltd, 2016)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 transverse magnetic field in a quantum adiabatic ... -
Irreversible work and internal friction in a quantum Otto cycle of a single arbitrary spin
Cakmak, Selcuk; Altintas, Ferdi; Gencten, Azmi; Mustecaplioglu, Ozgur E. (Springer, 2017)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 the cycle, generated by different control ... -
Lipkin-Meshkov-Glick model in a quantum Otto cycle
Cakmak, Selcuk; Altintas, Ferdi; Mustecaplioglu, Ozgur E. (Springer Heidelberg, 2016)The Lipkin-Meshkov-Glick model of two anisotropically interacting spins in a magnetic field is proposed as a working substance of a quantum Otto engine to explore and exploit the anisotropy effects for the optimization of ...
