Tailoring tensor network techniques to the quantics representation for highly inhomogeneous problems and few body problems
Jheng-Wei Li, Nicolas Jolly, Xavier Waintal
Tensor network techniques are becoming increasingly popular tools to solve partial differential equations within the so-called quantics representation. Their popularity stems from…
Matrix product states and first quantization
Jheng-Wei Li, Xavier Waintal
Common wisdom says that the entanglement of fermionic systems can be low in the second quantization formalism but is extremely large in the first quantization. Hence Matrix Product…
Finite-size subthermal regime in disordered SU(N)-symmetric Heisenberg chains
Dimitris Saraidaris, Jheng-Wei Li, Andreas Weichselbaum +2
SU(N) symmetry is incompatible with the many-body localized (MBL) phase, even when strong disorder is present. However, recent studies have shown that finite-size SU(2) systems exh…
Projector formalism for kept and discarded spaces of matrix product states
Andreas Gleis, Jheng-Wei Li, Jan von Delft
Any matrix product state has a set of associated kept and discarded spaces, needed for the description of , and changes thereof, respectively. These induce a…
