Fluctuations in irreversible quantum Otto engines
نویسندگان
چکیده
We derive the general probability distribution function of stochastic work for quantum Otto engines in which both isochoric and driving processes are irreversible due to finite time duration. The time-dependent fluctuations, average work, thermodynamic efficiency explicitly obtained a complete cycle operating with an analytically solvable two-level system. effects irreversibility originating from finite-time operation on efficiency, relative power fluctuations discussed.

Entangled quantum Otto heat engines based on two-spin systems with the Dzyaloshinski-Moriya interaction
We construct an entangled quantum Otto engine based on spin-1/2 systems undergoing Dzyaloshinski–Moriya (DM) interaction within a varying magnetic field. We investigate the influence of the DM interaction on basic thermodynamic quantities, including heat transfer, work done, and efficiency and find that the DM interaction importantly influences the engine's thermodynamics. We obtain an expressi...
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 کاملThe 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 کاملInternet search engines - fluctuations in document accessibility
An empirical investigation of the consistency of retrieval through Internet search engines is reported. The focus is on a characteristic related to size: the degree of consistency to which an engine retrieves documents. Does an engine always present the same relevant documents that are, or were, available in its database? We observed and identiied three types of uctuations in the result sets of...
متن کاملNonequilibrium fluctuations in quantum heat engines: theory, example, and possible solid state experiments
We study stochastic energetic exchanges in quantumheat engines. Due tomicroreversibility, these obey a fluctuation relation, called the heat enginefluctuation relation, which implies the Carnot bound: nomachine can have an efficiency greater thanCarnot’s efficiency. The stochastic thermodynamics of a quantumheat engine (including the joint statistics of heat andwork and the statistics of effici...
