Piezo-thermal effect in gas and plasma*

When compressed, a gas immersed in a potential field has been predicted to develop a temperature differential [1]. This phenomena, called the piezo-thermal effect, results in hot and cold regions corresponding to the locations of the maximum and minimum potential energy respectively. Previous numerical simulations confirmed this temperature differential for centrifugal and gravitational potentials. In this study, generalizations of the effect will be discussed. Although plasma features a number of complications, similar effects might also be imagined in compressing plasma. ~\\ ~\\ {[1]} V.I. Geyko and N.J. Fisch, Phys. Rev. E \textbf{94} 042113 (2016).
