Repulsion-Driven 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…
Spinless charged excitation at the interface between a conventional topological insulator and a topological Mott insulator
Cesar A. Gallegos, Andrew J. Millis, Steven R. White
We investigate the interface separating two topologically distinct insulating phases of matter using extensive density-matrix renormalization group calculations to study the triang…
Competing states in the triangular-lattice - Heisenberg model: a dynamical density-matrix renormalization group study
Shengtao Jiang, Steven R. White, Steven A. Kivelson +1
Previous studies of the triangular-lattice -- Heisenberg antiferromagnet have inferred the existence of a non-magnetic ground-state phase for an intermediate rang…
Quantum Hall to Chiral Spin Liquid transition in a Triangular Lattice Hofstadter-Hubbard Model
Cesar A. Gallegos, Rafael M. Magaldi, Andrew Millis +1
We investigate the weak interaction integer quantum Hall (IQH) phase, the intermediate interaction phase identified as a chiral spin liquid (CSL) and the transition between them in…
Site Basis Excitation Ansatz for Matrix Product States
Steven R. White
We introduce a simple and efficient variation of the tangent-space excitation ansatz used to compute elementary excitation spectra of one-dimensional quantum lattice systems using…
Ground-State-Based Model Reduction with Unitary Circuits
Shengtao Jiang, Steven R. White
We present a method to numerically obtain low-energy effective models based on a unitary transformation of the ground state. The algorithm finds a unitary circuit that transforms t…
