Thermodynamic uncertainty relations for bosonic Otto engines
نویسندگان
چکیده
We study two-mode bosonic engines undergoing an Otto cycle. The energy exchange between the two systems is provided by a tunable unitary bilinear interaction in mode operators modeling frequency conversion, whereas cyclic operation guaranteed relaxation to baths at different temperature after each interacting stage. By means of two-point-measurement approach we provide joint probability stochastic work and heat. derive exact expressions for heat fluctuations, identities showing interdependence among average extracted work, fluctuations efficiency, along with thermodynamic uncertainty relations signal-to-noise ratio observed entropy production. outline how presented can be suitably applied quantum alternative strokes.

Thermodynamic Uncertainty Relations
Bohr and Heisenberg suggested that the thermodynamical quantities of temperature and energy are complementary in the same way as position and momentum in quantum mechanics. Roughly speaking, their idea was that a definite temperature can be attributed to a system only if it is submerged in a heat bath, in which case energy fluctuations are unavoidable. On the other hand, a definite energy can o...
متن کاملThermodynamic uncertainty relations again: A reply to Lavenda
In a previous paper (Found. Phys. 29, 655, (1999)), we have presented a review of various approaches in the literature towards the derivation of so-called thermodynamic uncertainty relations in statistical thermodynamics. This review has been critical. We have argued that some of these approaches are sound, i.e. they reach a valid conclusion, albeit under restricted conditions, whereas others w...
متن کاملQuantum thermodynamic cycles and quantum heat engines.
In order to describe quantum heat engines, here we systematically study isothermal and isochoric processes for quantum thermodynamic cycles. Based on these results the quantum versions of both the Carnot heat engine and the Otto heat engine are defined without ambiguities. We also study the properties of quantum Carnot and Otto heat engines in comparison with their classical counterparts. Relat...
متن کاملDesigning optimal discrete-feedback thermodynamic engines
Feedback can be utilized to convert information into useful work, making it an effective tool for increasing the performance of thermodynamic engines. Using feedback reversibility as a guiding principle, we devise a method for designing optimal feedback protocols for thermodynamic engines that extracts all the information gained during feedback as work. Our method is based on the observation th...
متن کاملDescent Relations Among Bosonic D - branes
We show that the tachyonic kink solution on a pair of D-p-branes in the bosonic string theory can be identified with the D-(p − 1)-brane of the same theory. We also speculate on the possibility of obtaining the D-(p − 1)-brane as a tachyonic lump on a single D-p-brane. We suggest a possible reinterpretation of the first result which unifies these two apparently different descriptions of the D-(...
