Inverse Temperature 4-vector in Special Relativity
There exist several prescriptions for identifying the notion of temperature
in special relativity. We argue that the inverse temperature 4-vector is the only viable option from the laws of thermodynamics, and is a future-directed timelike 4-vector. Using a superfluidity thought
experiment, one can show that is not necessarily along the time
direction of the comoving frame of the system, as is usually thought. It is
conjectured that, for an isolated system, the 4-vector is determined from the
entropy-maximum principle.Comment: 11 pages, revised versio
