Heat Bath Algorithmic Cooled Quantum Otto Engines
Emre Köse, Selçuk Çakmak, Azmi Gençten +2
We suggest alternative quantum Otto engines, using heat bath algorithmic cooling with partner pairing algorithm instead of isochoric cooling. Liquid state nuclear magnetic resonanc…
Energy Levels of One Dimensional Anharmonic Oscillator via Neural Networks
Halil Mutuk
In this work, we obtained energy levels of one dimensional quartic anharmonic oscillator by using neural network system. Quartic anharmonic oscillator is a very important tool in q…
Asymptotic Iteration and Variational Methods for Gaussian Potential
Halil Mutuk
In this paper we studied approximate solutions of the radial Schrödinger equation with the attractive Gaussian potential. We used asymptotic iteration method and variational method…
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…
Lipkin-Meshkov-Glick Model in a Quantum Otto Cycle
Selçuk Çakmak, Ferdi Altintas, Özgür E. Müstecaplıoğlu
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 aniso…
