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…
Is charge order induced near an antiferromagnetic quantum critical point?
Xiaoyu Wang, Yuxuan Wang, Yoni Schattner +2
We investigate the interplay between charge order and superconductivity near an antiferromagnetic quantum critical point using sign-problem-free Quantum Monte Carlo simulations. We…
Superconductivity mediated by quantum critical antiferromagnetic fluctuations: The rise and fall of hot spots
Xiaoyu Wang, Yoni Schattner, Erez Berg +1
In several unconventional superconductors, the highest superconducting transition temperature is found in a region of the phase diagram where the antiferromagnetic transiti…
Competing Orders in a Nearly Antiferromagnetic Metal
Yoni Schattner, Max H. Gerlach, Simon Trebst +1
We study the onset of spin-density wave order in itinerant electron systems via a two-dimensional lattice model amenable to numerically exact, sign-problem-free determinantal quant…
Ising nematic quantum critical point in a metal: a Monte Carlo study
Yoni Schattner, Samuel Lederer, Steven A. Kivelson +1
The Ising nematic quantum critical point (QCP) associated with the zero temperature transition from a symmetric to a nematic {\it metal} is an exemplar of metallic quantum critical…
Enhancement of superconductivity near a nematic quantum critical point
Samuel Lederer, Yonatan Schattner, Erez Berg +1
We consider a low metallic superconductor weakly coupled to the soft fluctuations associated with proximity to a nematic quantum critical point (NQCP). We show that: 1) a BCS…
