Abstract

We consider an ideal Fermi gas of tachyons and derive a low temperature expansion of its thermodynamical functions. The tachyonic specific heat is linear dependent on temperature C_V=ε_Fk_FT and formally coincides with the specific heat of electron gas if the tachyon Fermi energy is defined as ε_F=√(k_F-m²).
