Abstract
In this paper, a GaAs quantum wire is considered with a semi-parabolic lateral confinement potential in the presence of a crossed electromagnetic field with the inclusion of Rashba SOI. The effects of pressure on thermodynamic properties have been studied. To this end, first, the eigenenergies for the system have been calculated considering Rashba spin effects under electric and magnetic fields. Then a numerical analysis is done to derive the partition function and obtain the system's thermodynamic properties. The results show that at low temperatures, all four thermodynamic properties don’t show much effect due to pressure. It is found that entropy increases with increasing hydrostatic pressure, whereas pressure affects mean energy and free energy in a different manner. A peak structure is observed in specific heat as a function of temperature where the peak position depends on hydrostatic pressure.
