High-field Josephson effect enabled by a moiré Hofstadter spectrum
A. Díez-Carlón, M. Cárdenes Wuttig, N. Wei +7
Magnetic fields generally suppress phase-coherent Josephson transport, limiting superconducting interferometry to relatively low fields. Here we show that moiré-engineered graphene…
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…
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…
Full characterization of measurement-induced transitions of a superconducting qubit
Thomas Connolly, Pavel D. Kurilovich, Vladislav D. Kurilovich +12
Repeated quantum non-demolition measurement is a cornerstone of quantum error correction protocols. In superconducting qubits, the speed of dispersive state readout can be enhanced…
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…
Subharmonic spin correlations and spectral pairing in Floquet time crystals
Alexander-Georg Penner, Harald Schmid, Leonid I. Glazman +1
Floquet time crystals are characterized by subharmonic behavior of temporal correlation functions. Studying the paradigmatic time crystal based on the disordered Floquet quantum Is…
Dirac-point spectroscopy of flat-band systems with the quantum twisting microscope
Nemin Wei, Felix von Oppen, Leonid I. Glazman
Motivated by the recent development of the quantum twisting microscope, we formulate a theory of elastic momentum-resolved tunneling across a planar tunnel junction between a monol…
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…
Spontaneous supercurrents and vortex depinning in two-dimensional arrays of -junctions
Simon Reinhardt, Alexander-Georg Penner, Johanna Berger +9
Two-dimensional arrays of ballistic Josephson junctions are important as model systems for synthetic quantum materials. Here, we investigate arrays of multiterminal junctions which…
Robust spectral pairing in the random-field Floquet quantum Ising model
Harald Schmid, Alexander-Georg Penner, Kang Yang +2
Motivated by an experiment on a superconducting quantum processor [Mi et al., Science 378, 785 (2022)], we study level pairings in the many-body spectrum of the random-field Floque…
Andreev Reflection in Scanning Tunneling Spectroscopy of Unconventional Superconductors
P. O. Sukhachov, Felix von Oppen, L. I. Glazman
We evaluate the differential conductance measured in a scanning tunneling microscopy (STM) setting at arbitrary electron transmission between an STM tip and a two-dimensional (2D)…
Deterministic phase slips in mesoscopic superconducting rings
I. Petkovic, A. Lollo, L. I. Glazman +1
The properties of one-dimensional superconductors are strongly influenced by topological fluctuations of the order parameter, known as phase slips, which cause the decay of persist…
Persistent currents in normal metal rings: comparing high-precision experiment with theory
A. C. Bleszynski-Jayich, W. E. Shanks, B. Peaudecerf +4
Quantum mechanics predicts that the equilibrium state of a resistive electrical circuit contains a dissipationless current. This persistent current has been the focus of considerab…
