Bounds on Thermal Efficiency from Inference
Ramandeep S. Johal, Renuka Rai, Guenter Mahler
The problem of inference is applied to the process of work extraction from two constant heat capacity reservoirs, when the thermodynamic coordinates of the process are not fully sp…
Comment on "Cooling by Heating: Refrigerator Powered by Photons"
Armen E. Allahverdyan, Karen V. Hovhannisyan, Guenter Mahler
Results obtained recently in Phys. Rev. Lett. 108, 120603 (2012) by Cleuren et al. apparently contradict to the third law of thermodynamics. We discuss a scenario for resolving thi…
Thermodynamic limits of dynamic cooling
Armen E. Allahverdyan, Karen V. Hovhannisyan, Dominik Janzing +1
We study dynamic cooling, where an externally driven two-level system is cooled via reservoir, a quantum system with initial canonical equilibrium state. We obtain explicitly the m…
Optimal refrigerator
Armen E. Allahverdyan, Karen Hovhannisyan, Guenter Mahler
We study a refrigerator model which consists of two -level systems interacting via a pulsed external field. Each system couples to its own thermal bath at temperatures and…
Optimal thermal refrigerator

We study a refrigerator model which consists of two -level systems interacting via a pulsed external field. Each system couples to its own thermal bath at temperatures and…
The second law of thermodynamics in the quantum Brownian oscillator at an arbitrary temperature
Ilki Kim, Guenter Mahler
In the classical limit no work is needed to couple a system to a bath with sufficiently weak coupling strength (or with arbitrarily finite coupling strength for a linear system) at…
