Discrete-time quantum walks with energy-dependent coins
Alana Spak dos Santos, Thiago T. Tsutsui, Fabiano M. Andrade
In this work, we extend the scattering quantum walk (SQW) framework to a lattice of energy-dependent point interactions. This yields, within the coined quantum walk (CQW) formalism…

Energy-space quantum walks: Thermalization without state convergence
Alana Spak dos Santos, Renato Moreira Angelo
We introduce energy-space quantum walks as a minimal framework to investigate equilibration, thermalization, and irreversibility from an effective-dynamics perspective. By mapping…
