Derivative of the truncated singular value and eigen decomposition
Jan Naumann
Recently developed applications in the field of machine learning and computational physics rely on automatic differentiation techniques, that require stable and efficient linear al…
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…
Hamiltonian truncation tensor networks for quantum field theories
Philipp Schmoll, Jan Naumann, Alexander Nietner +2
Understanding the equilibrium properties and out of equilibrium dynamics of quantum field theories are key aspects of fundamental problems in theoretical particle physics and cosmo…
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…
Epitaxial monolayers of magnetic 2D semiconductor FeBr grown on Au(111)
S. E. Hadjadj, C. González-Orellana, J. Lawrence +20
Magnetic two-dimensional (2D) semiconductors have attracted a lot of attention because modern preparation techniques are capable of providing single crystal films of these material…
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…
