Particle-Hole Ghost Interference in Superconductors
Archisman Panigrahi, Vladislav Poliakov, Leonid Levitov
Mirror-assisted optical interference can improve the fidelity of Young's double-slit interference. Here we discuss an electron analogue: particle-hole interference in superconducto…
Strain Response as a Probe of Spinons in Quantum Spin Liquids
Penghao Zhu, Archisman Panigrahi, Leonid Levitov +1
Quantum spin liquids (QSLs) host emergent, fractionalized fermionic excitations that are charge-neutral. Identifying clear experimental signatures of these excitations remains a ce…
Revealing electron-lattice decoupling by Peltier thermometry and nanoscale thermal imaging in graphene
Saurabh Kumar Srivastav, Tobias Völkl, Gary Quaresima +7
Electrical currents in low-dimensional quantum materials can drive electrons far from equilibrium, creating stark imbalance between electron and lattice temperatures. Yet, no exist…
Tomographic imaging of superconducting order using particle-hole interference
Archisman Panigrahi, Vladislav Poliakov, Leonid Levitov
Superconducting phases with exotic symmetries that differ from the underlying crystalline lattice are at the focus of superconductivity research. Yet, despite intense interest, det…
Proposal for spin superfluid quantum interference device
Yanyan Zhu, Eric Kleinherbers, Leonid Levitov +1
In easy-plane magnets, the spin superfluid phase was predicted to facilitate coherent spin transport. So far, experimental evidence remains elusive. In this Letter, we propose an i…
Chirality-induced pseudo-magnetic fields, flat bands and enhancement of superconductivity
Zhiyu Dong, Leonid Levitov, Patrick A. Lee
Systems in which exchange interactions couple carrier spins to a spin texture with a net chirality exhibit a spin-dependent Aharonov-Bohm effect, where the geometric gauge field an…
Spin chirality and fermion stirring in topological bands
Archisman Panigrahi, Vladislav Poliakov, Zhiyu Dong +1
We demonstrate that in metals, both normal and superconducting, orbital currents present in the ground state when time reversal symmetry (TRS) is broken, generate spin chirality. N…
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…
Charge and spin density wave orders in field-biased Bernal bilayer graphene
Zhiyu Dong, Patrick A. Lee, Leonid Levitov
This paper aims to clarify the nature of a surprising ordered phase recently reported in biased Bernal bilayer graphene that occurs at the phase boundary between the isospin-polari…
Spin-orbit proximity in MoS/bilayer graphene heterostructures
M. Masseroni, M. Gull, A. Panigrahi +11
Van der Waals heterostructures provide a versatile platform for tailoring electronic properties through the integration of two-dimensional materials. Among these combinations, the…
Signatures of electronic ordering in transport in graphene flat bands
Archisman Panigrahi, Leonid Levitov
Recently, a wide family of electronic orders was unveiled in graphene flat bands, such as spin- and valley-polarized phases as well as nematic momentum-polarized phases, stabilized…
Probing the tunable multi-cone bandstructure in Bernal bilayer graphene
Anna M. Seiler, Nils Jacobsen, Martin Statz +7
Controlling the bandstructure of Dirac materials is of wide interest in current research but has remained an outstanding challenge for systems such as monolayer graphene. In contra…
de Haas-van Alphen spectroscopy and fractional quantization of magnetic-breakdown orbits in moiré graphene
Matan Bocarsly, Matan Uzan, Indranil Roy +12
Quantum oscillations originating from the quantization of the electron cyclotron orbits provide ultrasensitive diagnostics of electron bands and interactions in novel materials. We…
Ultrafast Umklapp-assisted electron-phonon cooling in magic-angle twisted bilayer graphene
Jake Dudley Mehew, Rafael Luque Merino, Hiroaki Ishizuka +8
Carrier relaxation measurements in moiré materials offer a unique probe of the microscopic interactions, in particular the ones that are not easily measured by transport. Umklapp s…
Petahertz optical response in graphene
Matthias Baudisch, Andrea Marini, Joel D. Cox +8
The temporal dynamics of charge carriers determines the speed with which electronics can be realized in condensed matter, and their direct manipulation with optical fields promises…
