Effective Range and Optimal Frequency of Through-the-Earth Magnetic Induction Communication
Honglei Ma, Erwu Liu, Wei Ni +4
Magnetic induction communication (MIC) is a promising technology for through-the-earth (TTE) communication. Previous studies on the MIC range have often overlooked the impact of ed…
Chaotic dynamics of charged particles near weakly magnetized black holes in Einstein-ModMax Theory
Zijian Liu, Wenfu Cao
This paper presents a systematic study of the chaotic dynamics of charged test particles around purely magnetically charged black holes immersed in a uniform external magnetic fiel…
Discussion on the equivalence of two relativistic point-particle Lagrangians
Liubin Wang, Xin Wu
In 2021, Lei et al. claimed the equivalence between the two Lagrangians and $\mathcal{L}_2 = \frac{1}{2}mg_{μν} {\dot{x}}…
Coherence and Imaginarity as Resources in Quantum Circuit Complexity
Linlin Ye, Zhaoqi Wu, Nanrun Zhou
Quantum circuit complexity quantifies the minimal number of gates needed to realize a unitary transformation and plays a central role in quantum computation. In this work, we inves…
Third type of spacetime with the coexistence of integrability and non-integrability
Junjie Lu, Xin Wu
The integrability or non-integrability of a spacetime usually refers to whether the motion of massive or massless particles in the spacetime is integrable or not. The standard blac…
The Yang-Baxter Sigma Model from Twistor Space
Meer Ashwinkumar, Jitendra Pal
We derive a novel two-field four-dimensional integrable field theory (IFT) from 6d holomorphic Chern-Simons theory on twistor space. The four-dimensional IFT depends on a skew-symm…
