Probing the Quantum Noise of the Spinon Fermi Surface with NV Centers
Jun Yong Khoo, Falko Pientka, Patrick A. Lee +1
We study the transverse electrical conductivity and the corresponding magnetic noise of a two-dimensional U(1) spin liquid state with a spinon Fermi surface. We show that in the qu…
The universal shear conductivity of Fermi liquids and spinon Fermi surface states and its detection via spin qubit noise magnetometry
Jun Yong Khoo, Falko Pientka, Inti Sodemann
We demonstrate a remarkable property of metallic Fermi liquids: the transverse conductivity assumes a universal value in the quasi-static () limit for wavevectors $…
Quantum entanglement recognition
Jun Yong Khoo, Markus Heyl
Entanglement constitutes a key characteristic feature of quantum matter. Its detection, however, still faces major challenges. In this letter, we formulate a framework for probing…
Quantum Paracrystalline Shear Modes of the Electron Liquid
Jun Yong Khoo, Po-Yao Chang, Falko Pientka +1
Unlike classical fluids, a quantum Fermi liquid can support a long-lived and propagating shear sound wave at arbitrarily small wave vectors and frequencies, reminiscent of the tran…
The gate-tunable strong and fragile topology of multilayer-graphene on a transition metal dichalcogenide
Michael P. Zaletel, Jun Yong Khoo
We analyze the phase diagram of multilayer-graphene sandwiched between identical transition metal dichalcogenides. Recently realized in all van-der-Wall heterostructures, these san…
Spin-orbit driven band inversion in bilayer graphene by van der Waals proximity effect
J. O. Island, X. Cui, C. Lewandowski +10
Spin orbit coupling (SOC) is the key to realizing time-reversal invariant topological phases of matter. Famously, SOC was predicted by Kane and Mele to stabilize a quantum spin Hal…
