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…
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…
