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…

Local Spectroscopies Reveal Percolative Metal in Disordered Mott Insulators
Joseph C. Szabo, Kyungmin Lee, Vidya Madhavan +1
We elucidate the mechanism by which a Mott insulator transforms into a non-Fermi liquid metal upon increasing disorder at half filling. By correlating maps of the local density of…
