Crossover from Fast Scrambling to Operator Confinement Tuned by an Auxiliary Qubit
Ryan Buechele, Joseph Szabo, Nandini Trivedi
We demonstrate a static, disorder-free spin chain Hamiltonian which, by tuning the coupling to an auxiliary qubit, realizes a crossover between super-ballistic, ancilla-accelerated…

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…
