Time discretization of functional integrals
Numerical evaluation of functional integrals usually involves a finite (Lslice) discretization of the imaginary-time axis. In the auxiliary-field method, the L-slice approximant to the density matrix can be evaluated as a function of inverse temperature at any finite L as ˆρL(β) = [ˆρ1(β/L)]L, if th...
