Finite-Temperature Fermionic Casimir Effect in Horava-Lifshitz Theories
Computes the finite-temperature Casimir effect of a massless Lorentz-violating fermion field in the Horava-Lifshitz model obeying MIT bag boundary conditions on parallel plates. Using the generalized zeta function technique with the imaginary-time formalism, the Helmholtz free energy and Casimir pressure are obtained in closed form in the low- and high-temperature limits. For even critical exponent the free energy and pressure vanish in both limits; for odd critical exponent the pressure alternates between attractive and repulsive with the exponent, and thermal corrections always weaken the vacuum pressure.
Fermionic Casimir effect at finite temperature in Horava-Lifshitz theories Andrea Erdas∗
In this work, I study the finite temperature Casimir effect due to a massless fermion field that violates Lorentz invariance according to the Horava-Lifshitz theory. I investigate a fermion field tha…
