Distinguishing Mott and strain-induced anisotropic semimetals in magic-angle twisted bilayer graphene using Landau level spectroscopy
Keshav Singh, Juan Felipe Mendez-Valderrama, Erez Berg +2
Recent quantum twisting microscopy experiments [1] have provided unprecedented momentum- and energy-resolved imaging of magic-angle twisted bilayer graphene, revealing a stark dich…
Monte Carlo Studies of Twisted Bilayer Graphene: Strain and Thermal Fluctuations
Johannes S. Hofmann, Patrick Ledwith, Ashvin Vishwanath +2
We study the phase diagram of twisted bilayer graphene at charge neutrality as a function of twist angle , uniaxial heterostrain , and temperature using sign-pr…
Quantum Geometry Driven Crystallization: A Neural-Network Variational Monte Carlo Study
Agnes Valenti, Yaar Vituri, Yubo Yang +7
Wigner crystals are a paradigmatic form of interaction driven electronic order. A key open question is how Berry curvature and, more generally, quantum geometry reshape crystalliza…
Visualizing isospin magnetic texture and intervalley exchange interaction in rhombohedral tetralayer graphene
Nadav Auerbach, Surajit Dutta, Matan Uzan +13
The tunable band structure and nontrivial topology of multilayer rhombohedral graphene lead to a variety of correlated electronic states with isospin orders-meaning ordered states…
Anomalous currents and spontaneous vortices in spin-orbit coupled superconductors
Benjamin A. Levitan, Yuval Oreg, Erez Berg
We propose a mechanism which can generate supercurrents in spin-orbit coupled superconductors with charged magnetic inclusions. The basic idea is that through spin-orbit interactio…
Visualizing incommensurate inter-valley coherent states in rhombohedral trilayer graphene
Yiwen Liu, Ambikesh Gupta, Youngjoon Choi +13
ABC-stacked rhombohedral graphene multilayers exhibit a wide variety of electronic ground states characterized by broken isospin symmetry and superconductivity. Recently, indirect…
Incommensurate inter-valley coherent states in ABC graphene: collective modes and superconductivity
Yaar Vituri, Jiewen Xiao, Keshav Pareek +2
Recent experiments in ABC trilayer graphene detected superconductivity on the border of a phase transition to a symmetry-broken phase. In this work, we use unrestricted Hartree-Foc…
Measuring Phonon Dispersion and Electron-Phason Coupling in Twisted Bilayer Graphene with a Cryogenic Quantum Twisting Microscope
John Birkbeck, Jiewen Xiao, Alon Inbar +7
The coupling between electrons and phonons is one of the fundamental interactions in solids, underpinning a wide range of phenomena such as resistivity, heat conductivity, and supe…
Theory of phonon spectroscopy with the quantum twisting microscope
Jiewen Xiao, Erez Berg, Leonid I. Glazman +3
We develop a theory of probing phonon modes of van-der-Waals materials using the quantum twisting microscope. While elastic tunneling dominates the tunneling current at small twist…
Fluctuating magnetism and Pomeranchuk effect in multilayer graphene
Ludwig Holleis, Tian Xie, Siyuan Xu +9
Magnetism typically arises from the effect of exchange interactions on highly localized fermionic wave functions in f- and d-atomic orbitals. In rhombohedral multilayer graphene (R…
Linear spectroscopy of collective modes and the gap structure in two-dimensional superconductors
Benjamin A. Levitan, Yuval Oreg, Erez Berg +2
We consider optical response in multi-band, multi-layer two-dimensional superconductors. Within a simple model, we show that linear response to AC gating can detect collective mode…
Stability of quasiperiodic superconductors
Nicole Sabina Ticea, Julian May-Mann, Jiewen Xiao +2
We study the effects of quasiperiodicity on the stability of conventional and unconventional superconductors. Quasiperiodicity is modelled using the three-dimensional Aubry-Andre m…

Ludwig Holleis, Caitlin L. Patterson, Yiran Zhang +8
Superconductivity (SC) is a ubiquitous feature of graphite allotropes, having been observed in Bernal bilayers[1], rhombohedral trilayers[2], and a wide variety of angle-misaligned…
