Ticking clocks in quantum theory

R Silva, N Nurgalieva, H Wilming - arxiv preprint arxiv:2306.01829, 2023 - arxiv.org
We present a derivation of the structure and dynamics of a ticking clock by showing that for
finite systems a single natural principle serves to distinguish what we understand as ticking …

Exact Model Reduction for Continuous-Time Open Quantum Dynamics

T Grigoletto, Y Tao, F Ticozzi, L Viola - arxiv preprint arxiv:2412.05102, 2024 - arxiv.org
We consider finite-dimensional many-body quantum systems described by time-
independent Hamiltonians and Markovian master equations, and present a systematic …
