SU(N)-symmetric density matrix renormalization group


There is a lot of interest in finding and identifying novel

quantum materials. We here focus on d1 materials with a

strong spin-orbit coupling, which are supposed to realize a much

higher symmetry than SU(2), an emergent SU(4) symmetry [1,2].

In fact, α-ZrCl3 is expected to host the SU(4) Heisenberg model

on the honeycomb lattice with a large frustration [3]. These

SU(4) materials potentially realize a new type of spin liquids,

a gapped Z4 spin liquid [4]. We present new density matrix
