Variational optimization of projected entangled-pair states on the triangular lattice
Jan Naumann, Jens Eisert, Philipp Schmoll
We introduce a general corner transfer matrix renormalization group algorithm tailored to projected entangled-pair states on the triangular lattice. By integrating automatic differ…
Triangular lattice models of the Kalmeyer-Laughlin spin liquid from coupled wires
Tingyu Gao, Niklas Tausendpfund, Erik L. Weerda +3
Chiral spin liquids (CSLs) are exotic phases of interacting spins in two dimensions, characterized by long-range entanglement and fractional excitations. We construct a local Hamil…
Variationally optimizing infinite projected entangled-pair states at large bond dimensions: A split corner transfer matrix renormalization group approach
Jan Naumann, Erik Lennart Weerda, Jens Eisert +2
Projected entangled-pair states (PEPS) have become a powerful tool for studying quantum many-body systems in the condensed matter and quantum materials context, particularly with a…
An extended non-magnetic phase in the spin-1/2 Heisenberg antiferromagnet from the ruby to the maple-leaf lattice
Philipp Schmoll, Jan Naumann, Erik Lennart Weerda +2
The spin-1/2 Heisenberg antiferromagnet on the two-dimensional ruby and maple-leaf lattices provides a stringent test case for frustrated quantum magnetism, where semiclassical mag…
An introduction to infinite projected entangled-pair state methods for variational ground state simulations using automatic differentiation
Jan Naumann, Erik Lennart Weerda, Matteo Rizzi +2
Tensor networks capture large classes of ground states of phases of quantum matter faithfully and efficiently. Their manipulation and contraction has remained a challenge over the…
Tensor network study of the spin-1/2 Heisenberg anti-ferromagnet on the Shuriken lattice
Philipp Schmoll, Augustine Kshetrimayum, Jan Naumann +2
We investigate the ground state of the spin Heisenberg anti-ferromagnet on the Shuriken lattice, also in the presence of an external magnetic field. To this end, we employ…
