Numerical approaches for calculating the low-field dc Hall coefficient of the doped Hubbard model
Wen O. Wang, Jixun K. Ding, Brian Moritz +3
Using determinant Quantum Monte Carlo, we compare three methods of evaluating the dc Hall coefficient of the Hubbard model: the direct measurement of the off-diagonal current…
Nematic Antiferromagnetism and Deconfined Criticality from the Interplay between Electron-Phonon and Electron-Electron Interactions
Chao Wang, Yoni Schattner, Steven A. Kivelson
Systems with strong electron-phonon couplings typically exhibit various forms of charge order, while strong electron-electron interactions lead to magnetism. We use determinant qua…
Modeling unconventional superconductivity at the crossover between strong and weak electronic interactions
Morten H. Christensen, Xiaoyu Wang, Yoni Schattner +2
High-temperature superconductivity emerges in a host of different quantum materials, often in a region of the phase diagram where the electronic kinetic energy is comparable in mag…
Normal state properties of quantum critical metals at finite temperature
Avraham Klein, Yoni Schattner, Erez Berg +1
We study the effects of finite temperature on normal state properties of a metal near a quantum critical point to an antiferromagnetic or Ising-nematic state. At bosonic an…
Hierarchy of energy scales in an O(3) symmetric antiferromagnetic quantum critical metal: a Monte Carlo study
Carsten Bauer, Yoni Schattner, Simon Trebst +1
We present numerically exact results from sign-problem free quantum Monte Carlo simulations for a spin-fermion model near an symmetric antiferromagnetic (AFM) quantum critic…
Phases of a phenomenological model of twisted bilayer graphene
John F. Dodaro, Steven A. Kivelson, Yoni Schattner +2
We propose a lattice scale two-band generalized Hubbard model as a caricature of the electronic structure of twisted bilayer graphene. Various possible broken symmetry phases can a…
