Paths with two blocks in oriented graphs of large minimum semi-degree
Bin Chen, Xinmin Hou, Xinyu Zhou
Stein (2020) conjectured that for any positive integer , every oriented graph of minimum semi-degree greater than contains every oriented path of length . This conjectu…
Nonreciprocal transmission in a cavity-magnon system by rotational Sagnac effect
Zhe-Qi Yang, Si-Qi Lin, Zhi-Rong Zhong
Ultrahigh nonreciprocal transmission has been achieved in a cavity-magnon system, which consists of two whispering gallery modes (WGMs) and a single magnon mode within a magnetic i…
Fermi-liquid view of viscosity in cold and dense nucleon matter
Jianing Li, Weiyao Ke, Jin Hu
We develop a framework to calculate transport properties in cold, dense relativistic quasiparticle system within the Fermi-liquid theory at the mean-field level. Building on our pr…
Non-Hermitian topology in a single driven-dissipative Kerr-Cat qubit
Pei-Rong Han, Huiye Qiu, Hao-Long Zhang +3
The intriguing physical phenomena associated with exceptional points have established non-Hermitian physics as a frontier of modern research. Recent investigations have extended no…
Analytical solution and Lie algebra of the relativistic Boltzmann equation
Yi Wang, Xuan Zhao, Zhe Xu +1
In this work, we present a novel and more efficient approach to constructing the relativistic Bobylev, Krook, and Wu (BKW) solution [A. V. Bobylev, Sov. Phys. Dokl. 20, 820 (1976);…
Dynamically generating superflow in a bosonic ring via phase imprinting
Ke-Ji Chen, Fan Wu
Phase imprinting enables the dynamic generation of superflow in bosonic atoms, effectively overcoming traditional limitations such as vortex number constraints and heating effects.…
