Solvable Quantum Circuits with non-Markovian Influence Matrices
Samuel H. Pickering, Max McGinley, Bhavik Kumar +1
Influence matrices encode the action exerted on local subsystems by the rest of an extended quantum many-body system during their evolution. Thus, knowledge of the influence matrix…

Asymptotically Solvable Quantum Circuits
Samuel H. Pickering, Bruno Bertini
The discovery of chaotic quantum circuits with (partially) solvable dynamics has played a key role in our understanding of non-equilibrium quantum matter and, at the same time, has…

Phase transitions in full counting statistics of free fermions and directed polymers
James S. Pallister, Samuel H. Pickering, Dimitri M. Gangardt +1
We consider directed polymers in 1+1 spatial dimension under action of an external repulsive potential along a line. Using the exact mapping onto imaginary time evolution of free f…
