Theoretical constraints on reciprocal and non-reciprocal many-body radiative heat transfer
Cheng Guo, Shanhui Fan
We study the constraints on reciprocal and non-reciprocal many-body radiative heat transfer imposed by symmetry and the second law of thermodynamics. We show that the symmetry of s…
Relation between Photon Thermal Hall Effect and Persistent Heat Current in Nonreciprocal Radiative Heat Transfer
Cheng Guo, Yu Guo, Shanhui Fan
We study the photon thermal Hall effect and the persistent heat current in radiative heat transfer. We show that the photon thermal Hall effect is not a uniquely nonreciprocal effe…
Meron Spin Textures in Momentum Space
Cheng Guo, Meng Xiao, Yu Guo +2
We reveal the meron and antimeron spin textures in momentum space in a photonic crystal slab. These spin textures in momentum space have not been previously noted either in electro…
Mirror protected Dirac fermions on a Weyl semimetal NbP surface
Hao Zheng, Guoqing Chang, Shin-Ming Huang +15
The first Weyl semimetal was recently discovered in the NbP class of compounds. Although the topology of these novel materials has been identified, the surface properties are not y…
Incompatibility of Observables as State-Independent Bound of Uncertainty Relations
Yunlong Xiao, Cheng Guo, Fei Meng +2
For a pair of observables, they are called "incompatible", if and only if the commutator between them does not vanish, which represents one of the key features in quantum mechanics…
Joint product numerical range and geometry of reduced density matrices
Jianxin Chen, Cheng Guo, Zhengfeng Ji +4
The reduced density matrices of a many-body quantum system form a convex set, whose three-dimensional projection is convex in . The boundary of ma…
Criteria for directly detecting topological Fermi arcs in Weyl semimetals
Ilya Belopolski, Su-Yang Xu, Daniel Sanchez +16
The recent discovery of the first Weyl semimetal in TaAs provides the first observation of a Weyl fermion in nature and demonstrates a novel type of anomalous surface state, the Fe…
Atomic Scale Visualization of Quantum Interference on a Weyl Semimetal Surface by Scanning Tunneling Microscopy/Spectroscopy
Hao Zheng, Su-Yang Xu, Guang Bian +19
Weyl semimetals may open a new era in condensed matter physics, materials science and nanotech after graphene and topological insulators. We report the first atomic scale view of t…
Spin polarization and texture of the Fermi arcs in the Weyl Fermion semimetal TaAs
Su-Yang Xu, Ilya Belopolski, Daniel S. Sanchez +25
A Weyl semimetal is a new state of matter that host Weyl fermions as quasiparticle excitations. The Weyl fermions at zero energy correspond to points of bulk band degeneracy, Weyl…

Ilya Belopolski, Su-Yang Xu, Daniel Sanchez +16
The recent experimental discovery of a Weyl semimetal in TaAs provides the first observation of a Weyl fermion in nature and demonstrates a novel type of anomalous surface state ba…
Experimental discovery of a topological Weyl semimetal state in TaP
Su-Yang Xu, Ilya Belopolski, Daniel S. Sanchez +24
Weyl semimetals are expected to open up new horizons in physics and materials science because they provide the first realization of Weyl fermions and exhibit protected Fermi arc su…
Large Magnetoresistance over an Extended Temperature Regime in Monophosphides of Tantalum and Niobium
Chenglong Zhang, Cheng Guo, Hong Lu +5
We report extremely large magnetoresistance (MR) in an extended temperature regime from 1.5 K to 300 K in non-magnetic binary compounds TaP and NbP. TaP exhibits linear MR around $…
Magnetic tunneling induced Weyl node annihilation in TaP
Cheng-Long Zhang, Su-Yang Xu, C. M. Wang +20
Weyl nodes are topological objects in three-dimensional metals. Their topological property can be revealed by studying the high-field transport properties of a Weyl semimetal. Whil…
