Repulsion-Driven $p - i p$ Superconductivity in a Single Valley Revealed by DMRG

Cesar A. Gallegos, Omid Tavakol, Christopher Yang +2

We demonstrate repulsion-driven topological superconductivity of a single species of Dirac fermions, motivated by valley-polarized phases observed in two-dimensional materials such…

Revisiting magnon bound states: ferro-antiferromagnetic $J_{1} - J_{2}$ square-lattice model

Cesar A. Gallegos, A. L. Chernyshev

A comprehensive analysis of pairing and bound states of magnons in the Heisenberg $S = 1/2$ square-lattice $J_{1} - J_{2}$ ferro-antiferromagnetic model is presented. We highlight…

Phase Diagram of the Easy-Axis Triangular-Lattice $J_{1} - J_{2}$ Model

Cesar A. Gallegos, Shengtao Jiang, Steven R. White +1

The phase diagram of the $S = 1/2$ easy-axis triangular-lattice $J_{1} - J_{2}$ model is investigated using the density-matrix renormalization group and analytical insights. We fin…

Magnon interactions in the quantum paramagnetic phase of CoNb $_{2}$ O $_{6}$

Cesar A. Gallegos, A. L. Chernyshev

In this work, we study effects of magnon interactions in the excitation spectrum of CoNb $_{2}$ O $_{6}$ in the quantum paramagnetic phase in transverse field, where the $1/ S$ spin-wave t…
