Random-matrix models of monitored quantum circuits
Vir B. Bulchandani, S. L. Sondhi, J. T. Chalker
We study the competition between Haar-random unitary dynamics and measurements for unstructured systems of qubits. For projective measurements, we derive various properties of the…
Revised Enskog equation for hard rods
Vir B. Bulchandani
We point out that Percus's collision integral for one-dimensional hard rods [J. K. Percus, Physics of Fluids 12, 1560-1563 (1969)] does not preserve the thermal equilibrium state i…
Nonlinear breathers with crystalline symmetries
Frank Schindler, Vir B. Bulchandani, Wladimir A. Benalcazar
Nonlinear lattice models can support "discrete breather" excitations that stay localized in space for all time. By contrast, the localized Wannier states of linear lattice models a…
Quantum tasks assisted by quantum noise
Chuqiao Lin, Vir B. Bulchandani, Shivaji L. Sondhi
We introduce a notion of expected utility for quantum tasks and discuss some general conditions under which this is increased by the presence of quantum noise in the underlying res…
Unusual ergodic and chaotic properties of trapped hard rods
Debarshee Bagchi, Jitendra Kethepalli, Vir B. Bulchandani +4
We investigate ergodicity, chaos and thermalization for a one-dimensional classical gas of hard rods confined to an external quadratic or quartic trap, which breaks microscopic int…
