Thermodynamics of Charged Ideal Bose Gases in a Trap under a Magnetic Field

Jing-Han Fan, Qiang Gu, Wei Guo

We investigate thermodynamic properties of the rotating Bose gas in a trap, taking the charged ideal Bose gas in a magnetic field as an example. The system is equivalent to a neutral gas in a synthetic magnetic field. It is indicated that the Bose—Einstein condensation temperature is irrelevant to the magnetic field, conflicting with established intuition that the critical temperature decreases with the field increasing. The specific heat and Landau diamagnetization also exhibit intriguing behaviors.

Lost of Bosonic Coherence Due to the Fermionic Presence Under the Synthetic Magnetic Field

T. P. Polak

We have studied eects of inter-species interaction of the bosons in a BoseFermi mixture over a large regime of particle numbers under the synthetic magnetic eld.Analytically derived formulas for the density of states for several values of the magnetic elds f = 1/2, 1/3, 1/4, 1/6, 1/8 and 3/8 allows us to calculate, with a very good accuracy, the eective interaction between bosons.The presence of the Hofstadter buttery spectrum and fermionic species induces alternating sign potential between neutral bosonic atoms.Consequently bosons can attract or repulse each other whether sign of it strongly depends on the strength of the magnetic eld applied to the sample.
