Helical massive fermions under rotation

Understand

The properties of a massive fermion field undergoing rigid rotation at finite temperature and chemical potential are discussed.

• The polarisation imbalance is taken into account by considering a helicity chemical potential, which is dual to the helicity charge operator.
• The advantage of the proposed approach is that, as opposed to the axial current, the helicity charge current remains conserved at finite mass.
• A computation of thermal expectation values of the vector, helicity and axial charge currents, as well as of the fermion condensate and stress-energy tensor is provided.
