Kondo effect in the isotropic Heisenberg spin chain
Pradip Kattel, Parameshwar R. Pasnoori, J. H. Pixley +2
We investigate the boundary effects that arise when spin- impurities interact with the edges of the antiferromagnetic spin- Heisenberg chain through spin…
Boundary Quantum Phase Transitions in the Spin Heisenberg Chain with Boundary Magnetic Fields
Parameshwar R. Pasnoori, Junhyun Lee, J. H. Pixley +2
We consider the spin Heisenberg chain with boundary magnetic fields and analyze it using a combination of Bethe ansatz and density matrix renormalization group (DMRG)…
Chiral Kondo Lattice in Doped MoTe/WSe Bilayers
Daniele Guerci, Jie Wang, Jiawei Zang +3
We theoretically study the interplay between magnetism and a heavy Fermi liquid in the AB stacked transition metal dichalcogenide bilayer system MoTe/WSe in the regime in w…
The Aubry-Andre Anderson model: Magnetic impurities coupled to a fractal spectrum
Ang-Kun Wu, Daniel Bauernfeind, Xiaodong Cao +3
The Anderson model for a magnetic impurity in a one-dimensional quasicrystal is studied using the numerical renormalization group (NRG). The main focus is elucidating the physics a…
The low energy excitation spectrum of magic-angle semimetals
Jinjing Yi, Elio J. König, J. H. Pixley
We theoretically study the excitation spectrum of a two-dimensional Dirac semimetal in the presence of an incommensurate potential. Such models have been shown to possess magic-ang…
Designer Meron Lattice on the Surface of a Topological Insulator
Daniele Guerci, Jie Wang, J. H. Pixley +1
We present a promising route to realize spontaneous magnetic order on the surface of a 3D topological insulator by applying a superlattice potential. The superlattice potential cre…
