"Variational methods in quantum many-body physics."

  • Date: Jan 22, 2013
  • Time: 12:30 PM - 12:30 PM (Local Time Germany)
  • Speaker: Professor Frank Verstraete, Universität Wien, Faculty of Phys., Quantum Optics, -Nanophysics and -Information
  • Room: Herbert Walther Lecture Hall
  • Host: MPQ
"We will review successes and limitations of the variational method in quantum many-body physics; both the time-independent and the time dependent variational method will be illustrated. Special attention will be paid to the role of entanglement in strongly correlated systems and quantum field theory, to classes of wavefunctions that naturally encompass the required entanglement, and to Ansätze for describing elementary excitations and particles on top of the strongly correlated vacuum."
