Metamagnetism in UTe2: the roles of itinerancy and localization
Theodore I. Weinberger, Daniel Shaffer, Zheyu Wu +12
The metamagnetic transition in UTe plays a key role in stabilizing two enigmatic field-induced superconducting phases. One of these phases (SC2) is truncated by the transition,…
Giant nonlinear conductivity in 2D electron gas from substrate-induced dipolar scattering
Dmitry V. Chichinadze, Alexander Seidel, Zohar Nussinov
Despite a surge of interest in the nonlinear transport in 2D materials, a fundamental puzzle remains: existing theoretical frameworks are unable to quantitatively account for the g…
Metamagnetic ripples in the UTe2 high magnetic field phase diagram
Zheyu Wu, Hanyi Chen, Mengmeng Long +11
The heavy fermion metamagnet uranium ditelluride possesses two distinct magnetic field--induced superconducting states. One of these superconductive phases resides at magnetic fiel…
The Crossover from Ordinary to Higher-Order van Hove Singularity in a Honeycomb System: A Parquet Renormalization Group Analysis
Yueh-Chen Lee, Dmitry V. Chichinadze, Andrey V. Chubukov
We investigate the crossover from an ordinary van Hove singularity (OVHS) to a higher order van Hove singularity (HOVHS) in a model applicable to Bernal bilayer graphene and rhombo…
SU(4) symmetry in twisted bilayer graphene - an itinerant perspective
Dmitry V. Chichinadze, Laura Classen, Yuxuan Wang +1
We study symmetry-broken phases in twisted bilayer graphene at small filling above charge neutrality and at Van Hove filling. We argue that the Landau functionals for the particle-…
Valley magnetism, nematicity, and density wave orders in twisted bilayer graphene
Dmitry V. Chichinadze, Laura Classen, Andrey V. Chubukov
We analyze density-wave and Pomeranchuk orders in twisted bilayer graphene. This compliments our earlier analysis of the pairing instabilities. We assume that near half-filling of…
