Energy spectrum and current-phase relation of a nanowire Josephson junction close to the topological transition
Chaitanya Murthy, Vladislav D. Kurilovich, Pavel D. Kurilovich +3
A semiconducting nanowire proximitized by an -wave superconductor can be tuned into a topological state by an applied magnetic field. This quantum phase transition is marked by…
Almost Perfect Metals in One Dimension
Chaitanya Murthy, Chetan Nayak
We show that a one-dimensional quantum wire with as few as 2 channels of interacting fermions can host metallic states of matter that are stable against all perturbations up to $q^…
Bounds on chaos from the eigenstate thermalization hypothesis
Chaitanya Murthy, Mark Srednicki
We show that the known bound on the growth rate of the out-of-time-order four-point correlator in chaotic many-body quantum systems follows directly from the general structure of o…
Structure of chaotic eigenstates and their entanglement entropy
Chaitanya Murthy, Mark Srednicki
We consider a chaotic many-body system (i.e., one that satisfies the eigenstate thermalization hypothesis) that is split into two subsystems, with an interaction along their mutual…
Spectral response of Josephson junctions with low-energy quasiparticles
Anna Keselman, Chaitanya Murthy, Bernard van Heck +1
We study nanowire-based Josephson junctions shunted by a capacitor and take into account the presence of low-energy quasiparticle excitations. These are treated by extending conven…
