- Title: Quantum thermodynamics of coronal heating
- Authors: Robert Alicki and Alejandro Jenkins
- Abstract summary: convection in the stellar photosphere generates plasma waves by an irreversible process akin to Zeldovich superradiance and sonic booms.
Energy is mostly carried by megahertz Alfven waves that scatter elastically until they reach a height at which they can dissipate via mode conversion.

- Abstract: Using the quantum Markovian master equation, we show that convection in the
stellar photosphere generates plasma waves by an irreversible process akin to
Zeldovich superradiance and sonic booms. In the Sun, this mechanism is most
efficient in quiet regions with small magnetic fields. Energy is mostly carried
by megahertz Alfven waves that scatter elastically until they reach a height at
which they can dissipate via mode conversion. This gives the right power flux
for coronal heating and may account for chromospheric evaporation leading to
impulsive heat transport in the corona.

The energy of a movable wall of a cavity confining a quantum field can be converted into quanta of the field itself.
We employ quantum thermodynamics to show that this phenomenon can be employed as a tool to cool down the wall.
We show how to employ one laser drive to cool the entire system including the case when it is composed of other subsystems.

We experimentally demonstrate how to generate a state in condensed matter at moderate cryogenic temperatures.
This state is then used to efficiently remove microwave photons from a cavity.
Such an "anti-maser" device could be extremely beneficial for applications that would normally require cooling to millikelvin temperatures.

Our predictions are based on a microscopic model that is solved using kinetic equations of motion derived from Floquet-Born-Markov theory.

Expanding spacetime as well as the background oscillating inflaton field are mimicked in the non-relativistic limit.
The proposed experiment has the potential of exploring the evolution up to late times even beyond the weak coupling regime.
