Temporal Interference from Topological Transitions in Monitored Quantum Dynamics
Qingyuan Wang, Ruoyu Yin, Eli Barkai
The paper studies how stroboscopic measurements of a quantum system reveal temporal interference patterns that arise when a topological winding number changes, creating dark states…
Emergence of drifted diffusion in quantum walks with subspace restart
Liwei Qiao, Ruoyu Yin, Wei Zhang
The authors propose a subspace restart protocol that periodically resets only the internal (coin) degrees of freedom of a discrete-time quantum walk while leaving its spatial distr…
Restart uncertainty relation for monitored quantum dynamics
Ruoyu Yin, Qingyuan Wang, Sabine Tornow +1
We introduce a novel time-energy uncertainty relation within the context of restarts in monitored quantum dynamics. Initially, we investigate the concept of ``first hitting time''…
Constructing Berry-Maxwell equations with Lorentz invariance and Gauss' law of Weyl monopoles in 4D energy-momentum space
Yiming Pan, Ruoyu Yin
We present the construction of a reciprocal electromagnetic field by extending the Berry curvatures into four-dimensional (4D) energy-momentum space. The resulting governing equati…
