High-field Josephson effect enabled by a moiré Hofstadter spectrum
A. DÃez-Carlón, M. Cárdenes Wuttig, N. Wei +7
The paper demonstrates that graphene/hBN Josephson junctions engineered with a moiré superlattice can maintain phase‑coherent superconducting transport at magnetic fields up to 6 T…
Lifetime and spectral function of topological heavy fermions
Nemin Wei, Felix von Oppen, Leonid I. Glazman
Twisted bilayer graphene provides a paradigmatic platform for exploring the interplay between electronic topology and strong correlations. Within the topological heavy fermion mode…
Twisted Bilayer Graphene Lifetimes At Integer Fillings: An Analytic Result
Haoyu Hu, Yuelin Shao, Lorenzo Crippa +5
Twisted bilayer graphene near integer fillings hosts correlated single-particle excitations whose dispersion and linewidth are increasingly accessible experimentally. We study thes…
Axion electrodynamics and giant magnetic birefringence in Weyl excitonic insulators
Anna Grigoreva, Anton Andreev, Leonid Glazman
We study the electromagnetic (EM) response of the excitonic insulator phase of a time-reversal (TR) invariant Weyl semimetal (WSM). At low temperatures, the system develops two exc…
Tunneling spectroscopy of two-dimensional superconductors with the quantum twisting microscope
Nemin Wei, Felix von Oppen, Leonid I. Glazman
The ongoing discoveries of graphene-based superconductors underscore the quest to understand the structure of new superconducting orders. We develop a theory that facilitates the u…
Theory of plasmon spectroscopy with the quantum twisting microscope
Nemin Wei, Francisco Guinea, Felix von Oppen +1
We consider plasmon-assisted electron tunneling in a quantum twisting microscope (QTM). The dependence of the differential conductance on the two control parameters of the QTM -- t…
