The Quantum Harmonic Otto Cycle
The quantum Otto cycle serves as a bridge between the macroscopic world of heat engines and the quantum regime of thermal devices composed from a single element. We compile recent studies of the quantum Otto cycle with a harmonic oscillator as a working medium. This model has the advantage that it is analytically trackable. In addition, an experimental realization has been achieved, employing a...
متن کاملAlternative Approach for predicting the performance of Irreversible Otto Cycle
The performance of an air-standard Otto cycle with variation of cycle peak temperature and variable specific heats of working fluid is analyzed. The relations between the power output and the compression ratio, between the thermal efficiency and the compression ratio, as well as the optimal relation between power output and the efficiency of the cycle are derived by detailed numerical examples....
متن کاملMagnetic Quantum Otto Engine for the Single-Particle Landau Problem
We study the effect of the degeneracy factor in the energy levels of the well-known Landau problem for a magnetic quantum Otto engine. The scheme of the cycle is composed of two quantum adiabatic processes and two quantum isomagnetic processes driven by a quasi-static modulation of external magnetic field intensity. We derive the analytical expression of the relation between the magnetic field ...
متن کاملOtto Loewi
The end of the 19th century was the starting point of many discoveries in the field of the neurophysiology. At that time, only basic technical approaches were available, and new discoveries depended on few results and lots of deductions. Furthermore, the scientific community was often debating on theoretical speculations and was often divided. I have chosen to present a German neurophysiologist...

*Professor of Medicine, T.N. Medical College (Retd.), Hon. Physician, Bhatia Hospital, Mumbai; **Consultant Internal Medicine, Kokilaben Dhirubhai Ambani Hospital, Mumbai O Loewi (1873 1961) studied medicine at the University of Strasbourg and obtained his medical degree in 1896. Thereafter he worked in London under Starling. In 1905, he went to Austria and held professorial positions at the Un...
