Quantum order by disorder in Frustrated Spin Nanotubes
João C. Getelina, Zekun Zhuang, Premala Chandra +3
We investigate quantum order by disorder in a frustrated spin nanotube formed by wrapping a - Heisenberg model at 45 around a cylinder. Using Schwinger boson theo…
TBG as Topological Heavy Fermion: II. Analytical approximations of the model parameters
Dumitru Călugăru, Maksim Borovkov, Liam L. H. Lau +3
The recently-introduced Topological Heavy Fermion (THF) model [Phys. Rev. Lett. 129, 047601] of twisted bilayer graphene (TBG) aims to reconcile the quantum-dot-like electronic str…
Topological Mixed Valence Model for Twisted Bilayer Graphene
Liam L. H. Lau, Piers Coleman
Song and Bernevig (SB) have recently proposed a topological heavy fermion description of the physics of magic angle twisted bilayer graphene (MATBG), involving the hybridization of…
Analytic calculation of the vison gap in the Kitaev spin liquid
Aaditya Panigrahi, Piers Coleman, Alexei Tsvelik
Although the ground-state energy of the Kitaev spin liquid can be calculated exactly, the associated vison gap energy has to date only been calculated numerically from finite size…
Triplet pairing, orbital selectivity and correlations in Iron-based superconductors
Yashar Komijani, Elio Koenig, Piers Coleman
We use a slave-boson approach to study the band renormalization and pair susceptibility in the normal state of Iron-based superconductors in presence of strong Coulomb repulsion an…
Matrix Product Study of Spin Fractionalization in the 1D Kondo Insulator
Jing Chen, E. Miles Stoudenmire, Yashar Komijani +1
The Kondo lattice is one of the classic examples of strongly correlated electronic systems. We conduct a controlled study of the Kondo lattice in one dimension, highlighting the ro…
