Emergent boundary-memory from unitarity constraints in a minimal two interacting quantum particles
Ibrahim Yahaya Muhammad, Tanapat Deesuwan, Monsit Tanasittikosol
We construct a simple model of two particles mutually attracting/repulsing in a one-dimensional lattice and investigate the corresponding dynamics. We show that enforcing reversibl…

Cumulant-based quantum relative Rényi functional
Atirat Meunson, Tanapat Deesuwan
We introduce a new cumulant-based quantum relative Rényi functional as a candidate quantum Rényi divergence, derived from the cumulant-generating function (CGF) of the quantum re…

Spatial entanglement between two quantum walkers with exchange symmetric coins
Ibrahim Yahaya Muhammad, Tanapat Deesuwan, Sikarin Yoo-Kong +2
We investigate how the initial and final exchange symmetries between the two-coin states influence the spatial entanglement dynamics between the two corresponding quantum walkers.…
