Heat Superconductivity
Junren Shi, Zhengqian Cheng
Electrons/atoms can flow without dissipation at low temperature in superconductors/superfluids. The phenomenon known as superconductivity/superfluidity is one of the most important…
Coupling the valley degree of freedom to antiferromagnetic order
Xiao Li, Ting Cao, Qian Niu +2
Conventional electronics are based invariably on the intrinsic degrees of freedom of an electron, namely, its charge and spin. The exploration of novel electronic degrees of freedo…
Topological Invariants of Metals and Related Physical Effects
Jianhui Zhou, Hua Jiang, Qian Niu +1
The total reciprocal space magnetic flux threading through a closed Fermi surface is a topological invariant for a three-dimensional metal. For a Weyl metal, the invariant is non-z…
Intra-valley Spin-triplet Superconducting Pairing in Lightly Doped Graphene
Jianhui Zhou, Tao Qin, Junren Shi
We analyze various possible superconducting pairing states and their relative stabilities in lightly doped graphene. We show that, when inter-sublattice electron-electron attractiv…
Stabilizing topological phases in graphene via random adsorption
Hua Jiang, Zhenhua Qiao, Haiwen Liu +2
We study the possibility of realizing topological phases in graphene with randomly distributed adsorbates. When graphene is subjected to periodically distributed adatoms, the enhan…
