Spin Polarons in Flat Band Ferromagnets
Saranesh Prembabu, Rahul Sahay, Stefan Divic +1
Spin polarons are bound states of electrons and spin-flips that form above spin polarized electronic insulators.These bound states conventionally form in one of two settings: in fr…
Robust superconductivity upon doping chiral spin liquid and Chern insulators in a Hubbard-Hofstadter model
Clemens Kuhlenkamp, Stefan Divic, Michael P. Zaletel +2
Demonstrating superconductivity in purely repulsive Hubbard models is a compelling goal which underscores the counter-intuitive ability of Coulomb interactions to mediate supercond…
Anyon Superconductivity from Topological Criticality in a Hofstadter-Hubbard Model
Stefan Divic, Valentin Crépel, Tomohiro Soejima +4
We argue that the combination of strong repulsive interactions and high magnetic fields can generate electron pairing and superconductivity. Inspired by the large lattice constants…
Tensor Network Python (TeNPy) version 1
Johannes Hauschild, Jakob Unfried, Sajant Anand +27
TeNPy (short for 'Tensor Network Python') is a python library for the simulation of strongly correlated quantum systems with tensor networks. The philosophy of this library is to a…
Chiral Spin Liquid and Quantum Phase Transition in the Triangular Lattice Hofstadter-Hubbard Model
Stefan Divic, Tomohiro Soejima, Valentin Crépel +2
Recent advances in moiré engineering motivate the study of lattice models of strongly-correlated electrons subjected to substantial orbital magnetic flux. We analyze the triangular…
Superconductivity in a Topological Lattice Model with Strong Repulsion
Rahul Sahay, Stefan Divic, Daniel E. Parker +8
The highly tunable nature of synthetic quantum materials -- both in the solid-state and cold atom contexts -- invites examining which microscopic ingredients aid in the realization…
Beyond the Imitation Game: Quantifying and extrapolating the capabilities of language models
Aarohi Srivastava, Abhinav Rastogi, Abhishek Rao +448
Language models demonstrate both quantitative improvement and new qualitative capabilities with increasing scale. Despite their potentially transformative impact, these new capabil…
Magnetic skyrmion crystal at a topological insulator surface
Stefan Divic, Henry Ling, T. Pereg-Barnea +1
We consider a magnetic skyrmion crystal formed at the surface of a topological insulator. Incorporating the exchange interaction between the helical Dirac surface states and the pe…
Tunable skyrmion crystals and topological quantum oscillations in magnetic metals
Sopheak Sorn, Stefan Divic, Arun Paramekanti
Skyrmions are spatially localized magnetic swirls which carry a nonzero integer topological charge. We study crystals of skyrmions in a two-dimensional ferromagnet model with chira…
