DESCRIPTION:Speaker: Martin Ganahl\nhosted by Maksym Serbyn\nAbstract: Over
  the past several years\, continuous Matrix Product States (cMPS) have eme
 rged as a powerful tool for obtaining non-perturbative ground state and ex
 cited state properties of interacting quantum field theories (QFTs) in (1+
 1)d. At the heart of the cMPS lies an efficient parametrization of manybod
 y wavefunctions directly in the continuum\, that enables one to obtain gro
 und states of QFTs via imaginary time evolution.\nIn the first part of my 
 talk I will give a general introduction to the cMPS formalism. In the seco
 nd part\, I will then discuss a new method for cMPS optimization\, based o
 n energy gradient instead of the usual imaginary time evolution. This new 
 method overcomes several problems associated with imaginary time evolution
 \, and allows to perform calculations at much lower cost / higher accuracy
  than previously possible.
