DESCRIPTION:\n\nMany interesting strongly interacting Quantum Field Theori
es are not amenable to analytical treatment. This workshop will focus on s
ystematic numerical approaches to such theories relying on the quantum Ham
iltonian\, including Truncated Spectrum Approach\, Light Front Quantizatio
n\, Matrix Product States and Tensor Networks. Such methods provide a viab
le alternative to Lattice Monte Carlo simulations. Their advantage is the
ability to access real-time observables\, and to study Renormalization Gro
up flows originating from strongly-interacting fixed points.\n\n \n\n \n
