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…
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…
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…
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…
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…
