Nematic metal in a multi-valley electron gas: Variational Monte Carlo analysis and application to AlAs
Agnes Valenti, Vladimir Calvera, Steven A. Kivelson +2
The two-dimensional electron gas is of fundamental importance in quantum many-body physics. We study a minimal extension of this model with (as opposed to full rotational) sy…
Stoner ferromagnetism in a momentum-confined interacting 2D electron gas
Ohad Antebi, Ady Stern, Erez Berg
In this work we investigate the ground state of a momentum-confined interacting 2D electron gas, a momentum-space analog of an infinite quantum well. The study is performed by comb…
Weakly damped bosons and precursor gap in the vicinity of an antiferromagnetic metallic transition
Ori Grossman, Erez Berg
We study the electronic spectral function of a metal in the vicinity of an antiferromagnetic (AFM) quantum critical point, focusing on a situation where the bare bandwidth of the s…
Electron-phonon coupling and competing Kekulé orders in twisted bilayer graphene
Yves H. Kwan, Glenn Wagner, Nick Bultinck +3
Recent scanning tunneling microscopy experiments [K.P. Nuckolls et al., arXiv:2303.00024] have revealed the ubiquity of Kekulé charge-density wave order in magic-angle twisted bila…
Robust Fermi liquid instabilities in sign problem-free models
Ori Grossman, Erez Berg
Determinant Quantum Monte Carlo (DQMC) is a powerful numerical technique to study many-body fermionic systems. In recent years, several classes of sign-free (SF) models have been d…
Investigation of Planckian behavior in a high-conductivity oxide: PdCrO
Elina Zhakina, Ramzy Daou, Antoine Maignan +12
The layered delafossite metal PdCrO is a natural heterostructure of highly conductive Pd layers Kondo coupled to localized spins in the adjacent Mott insulating CrO layers.…
