Condensed-Matter Physics & Materials Science Seminar

"Non-abelian symmetries and applications in tensor networks"

Presented by Andreas Weichselbaum, Brookhaven National Lab

Thursday, March 29, 2018, 1:30 pm — ISB Bldg. 734 Conf. Rm. 201 (upstairs)

I will give a brief introduction to tensor network states
with focus on exploiting all symmetries, abelian and non-abelian alike. I will briefly motivate a generic framework for finite-dimensional Lie algebras, which has been fully implemented in the tensor library QSpace [1]. The latter was already put under extensive scrutiny over the past couple of years. Along it already also gave rise to a range of excellent applications. Here, in particular, I will briefly highlight 1D density matrix renormalization group (DMRG) calculations on SU(N) Heisenberg ladders, 2D projected entangled pair state (PEPS) simulations on Spin-1 Kagome [2], and infinite-dimensional dynamical mean-field theory (DMFT) simulations on Hund's metals [3].
