Software

C2SEPEM is currently supporting three excited-states software:
  • BerkeleyGW is a many-body perturbation theory code for excited states, using the GW method and the GW plus Bethe-Salpeter equation (GW-BSE) method to solve respectively for quasiparticle excitations and optical properties of materials, nanostructures, and molecues.
  • StochasticGW utilizes the stochastic sampling technique for GW calculations and reaches linear scaling in system size.
  • NanoGW is based on the solution of the Casida equation employing a real-space grid approach.
