Direct generation of time-energy-entangled W triphotons in atomic vapor
Kangkang Li, Jianming Wen, Yin Cai +6
Sources of entangled multiphotons are not only essential for fundamental tests of quantum foundations, but are also the cornerstone of a variety of optical quantum technologies tod…
Topological magnons in Kitaev magnets with finite Dzyaloshinskii-Moriya interaction at high field
Kangkang Li
There have been intensive studies on Kitaev materials for the sake of the realization of exotic states such as quantum spin liquid and topological orders. In realistic materials, t…
Thermal Hall conductivity with sign change in the Heisenberg-Kitaev kagome magnet
Kangkang Li
The Heisenberg-Kitaev (HK) model on various lattices have attracted a lot of attention because they may lead to exotic states such as quantum spin liquid and topological orders. Th…
Quantum Transports in Two-Dimensions with Long Range Hopping: Shielding, Localization and the Extended Isolated State
Si-Si Wang, Kangkang Li, Yi-Ming Dai +3
We investigate the effects of disorder and shielding on quantum transports in a two dimensional system with all-to-all long range hopping. In the weak disorder, cooperative shieldi…
Hierarchical dimensional crossover of an optically-trapped quantum gas with disorder
KangKang Li, Zhaoxin Liang
Dimensionality serves as an indispensable ingredient in any attempt to formulate the low-dimensional physics, and studying the dimensional crossover at a fundamental level is chall…
Topological spin excitations observed in a three-dimensional antiferromagnet
Weiliang Yao, Chenyuan Li, Lichen Wang +7
Band topology, or global wave-function structure that enforces novel properties in the bulk and on the surface of crystalline materials, is currently under intense investigations f…
Weyl and nodal ring magnons in three-dimensional honeycomb lattices
Kangkang Li, Jiangping Hu
We study the topological properties of magnon excitations in a wide class of three dimensional (3D) honeycomb lattices with ferromagnetic ground states. It is found that they host…
Dirac and nodal line magnons in three-dimensional antiferromagnets
Kangkang Li, Chenyuan Li, Jiangping Hu +2
We study the topological properties of magnon excitations in three-dimensional antiferromagnets, where the ground state configuration is invariant under time-reversal followed by s…
Electromagnetic instability and Schwinger effect in the Witten-Sakai-Sugimoto model with D0-D4 background
Wenhe Cai, Kang-le Li, Si-wen Li
Using the Witten-Sakai-Sugimoto model in the D0-D4 background, we holographically compute the vacuum decay rate of the Schwinger effect in this model. Our calculation contains the…
Spin-filtered and Spatially Distinguishable Crossed Andreev Reflection in a Silicene-Superconductor Junction
Kangkang Li, Yan-Yang Zhang
We theoretically investigate the quantum transports in a junction between a superconductor and a silicene nanoribbon, under the effect of a magnetic exchange field. We find that fo…
