Thermal momentum distribution from path integrals with shifted boundary conditions
Thermal momentum distribution path integrals shifted boundary conditions
2010/12/27
For a thermal field theory formulated in the grand canonical ensemble, the distribution of the total momentum is an observable characterizing the thermal state. We show that its cumulants are related...
