Thermal conductivity in one-dimensional nonlinear disordered lattices: Two kinds of scattering effects of hard-type and soft-type anharmonicities
Jianjin Wang, Chi Xiong, Daxing Xiong
The amorphous solids can be theoretically modeled by anharmonic disordered lattices. However, most of theoretical studies on thermal conductivity in anharmonic disordered lattices…
Unusual slow energy relaxation induced by mobile discrete breathers in one-dimensional lattices with next-nearest-neighbor coupling
Bin Xu, Jun Zhang, Wei Zhong +2
We study the energy relaxation process in one-dimensional (1D) lattices with next-nearest-neighbor (NNN) couplings. This relaxation is produced by adding damping (absorbing conditi…
Relativistic quantum information as radiation reaction: entanglement entropy and self-force of a moving mirror analog to the CGHS black hole
Aizhan Myrzakul, Chi Xiong, Michael R. R. Good
The CGHS black hole has a spectrum and temperature that corresponds to an accelerated reflecting boundary condition in flat spacetime. The beta coefficients are identical to a movi…
Axionic excitation from QCD Condensate
Chi Xiong
A complex order parameter is used for describing inhomogeneous quark condensate and its phase is decomposed into a regular part and a singular part. An emergent gauge symmetry is f…
Vectorizing Quantum Turbulence Vortex-Core Lines for Real-Time Visualization
Daoming Liu, Chi Xiong, Xiaopei Liu
Vectorizing vortex-core lines is crucial for high-quality visualization and analysis of turbulence. While several techniques exist in the literature, they can only be applied to cl…
QCD strings and the U(1) problem
Chi Xiong
We promote the usual QCD -parameter to a field and interpret it as the phase of the quark condensate, which becomes nontrivial when topological defects, vortices in our formulat…
