Bloch Oscillations and Landau-Zener Transitions in Flat-Band Lattices with Quadratic and Linear Band Touchings

Chenhaoyue Wang, Carlos J. Garcia-Cervera, Amartya S. Banerjee·Oct 3, 2025

Bloch oscillations (BOs) describe the coherent oscillatory motion of electrons in a periodic lattice under a constant external electric field. Deviations from pure harmonic wave packet motion or irregular Bloch oscillations can occur due to Zener tun...

Non-reciprocal Synchronization in Thermal Rydberg Ensembles

Yunlong Xue, Zhengyang Bai·Oct 3, 2025

Optical non-reciprocity is a fundamental phenomenon in photonics. It is crucial for developing devices that rely on directional signal control, such as optical isolators and circulators. However, most research in this field has focused on systems in ...

Universal classical-quantum channel resolvability and private channel coding

Takaya Matsuura, Masahito Hayashi, Min-Hsiu Hsieh·Oct 3, 2025

We address the problem of constructing fully universal private channel coding protocols for classical-quantum (c-q) channels. Previous work constructed universal decoding strategies, but the encoder relied on random coding, which prevents fully unive...
