Numerical treatment of two-dimensional strongly-correlated systems is both extremely
challenging and of fundamental importance. Infinite projected entangled-pair states (PEPS) …

An important class of model Hamiltonians for investigation of topological phases of matter
consists of mobile, interacting particles on a lattice subject to a semiclassical gauge field, as …

The spin-$1/2$ Heisenberg antiferromagnet on the two-dimensional ruby and maple-leaf
lattices is emerging as a new paradigmatic model of frustrated quantum magnetism, with the …

While gauge symmetry is a well-established requirement for representing topological orders
in projected entangled-pair state (PEPS), its impact on the properties of low-lying excited …

Motivated by the recent experimental study on a quantum Ising magnet $\text {K} _2\text
{Co}(\text {SeO} _3) _2 $ where spectroscopic evidence of zero-field supersolidity is …

We employ tensor network renormalization to explore the dynamical spectra of the easy-axis
triangular-lattice antiferromagnet (TLAF) in a magnetic field. Our analysis identifies two …
