This derivation shares many formal similarities with that given for the variational principle in section 3.3.1. However in the DMC method the imaginary time evolution results in excited states ...

The quasiparticle excitation energies are the energies for adding an electron to the system or subtracting one from it. A quasiparticle energy has both real and imaginary parts, the latter giving the ...
