Long-range phase coherence and phase patterns in hybrid Josephson junction arrays
Xi Wang, Asbjørn C. C. Drachmann, Candice Thomas +5
The coherence of superconductivity and its suppression near a quantum phase transition is governed by the interplay between local pairing and macroscopic phase coherence. Using sca…
Magnetic field induced phenomena in Kitaev spin liquids
Shi Feng, Nandini Trivedi
Quantum spin liquids (QSLs) host a variety of fractionalized particles. In Kitaev's paradigmatic honeycomb model a spin- fractionalizes into flux due to emergen…
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…
Detection of anyon braiding through pump-probe spectroscopy
Xu Yang, Ryan Buechele, Nandini Trivedi
We show that the braiding of anyons in a quantum spin liquid leaves a distinct dynamical signature in the nonlinear pump-probe response. Using a combination of exact diagonalizatio…
Partial Wavefunction Collapse Under Repeated Weak Measurement of a non-Conserved Observable
Carter Swift, Nandini Trivedi
Two hallmarks of quantum non-demolition (QND) measurement are the ensemble-level conservation of the expectation value of the measured observable and the eventual, inevitable c…
