Topological quantum materials coupled with magnetism can provide a platform for realizing rich exotic physical phenomena, including anomalous Hall effect, axion electrodynamics and Majorana fermions. However, these unusual effects typically require extreme experimental conditions such as ultralow temperature or sophisticate material growth fabrication. Recently, new intrinsic magnetic topological insulators were proposed in MnBi2Te4-family compounds - on which could be realized under much...
Topological superconductors (TSCs) are unconventional with bulk superconducting gap and in-gap Majorana states on the boundary that may be used as topological qubits for quantum computation. Despite their importance in both fundamental research applications, natural TSCs very rare. Here, combining state of art synchrotron laser-based angle-resolved photoemission spectroscopy, we investigated a stoichiometric transition metal dichalcogenide (TMD), 2M-WS2 temperature 8.8 K (the highest among...
The van der Waals ferromagnet $\mathrm{F}{\mathrm{e}}_{3}\mathrm{GeT}{\mathrm{e}}_{2}$ has attracted great research attention recently due to its extraordinary properties. Here, using high-resolution angle-resolved photoemission spectroscopy, we systematically investigate the temperature evolution of electronic structure bulk $\mathrm{F}{\mathrm{e}}_{3}\mathrm{GeT}{\mathrm{e}}_{2}$. We observe largely dispersive energy bands with exchange splitting that are in overall agreement our...
Increasing evidence suggests that primary trigeminal neuralgia (TN), including classical TN (CTN) and idiopathic (ITN), share biological, neuropsychological, clinical features, despite differing diagnostic criteria. Neuroimaging studies have shown neurovascular compression (NVC) differences in these disorders. However, changes brain dynamics across two subtypes remain unknown. The authors aimed to examine the functional connectivity CTN, ITN, pain-free controls. A total of 93 subjects, 50...
(Quasi-)one-dimensional systems exhibit various fascinating properties such as Luttinger liquid behavior, Peierls transition, novel topological phases, and the accommodation of unique quasiparticles (e.g., spinon, holon, soliton, etc.). Here we study molybdenum blue bronze A0.3MoO3 (A = K, Rb), a canonical quasi-one-dimensional charge-density-wave material, using laser-based angle-resolved photoemission spectroscopy. Our experiment suggests that normal phase is prototypical liquid, from...
Abstract Quantum anomalous Hall effect (QAHE) characterized by the presence of multiple non-dissipertive edge conduction channels has garnered substantial research interest owing to its applications in energy-conserving electronic devices. However, observation is constrained extremely low temperatures, which pose challenges for practical implementation. In context, we delineate interrelationship between Nernst and quantum through Berry curvature Bi/FeBi2Te4 heterostructure. Initially, under...

Topological materials host fascinating low dimensional gapless states at the boundary. As a prominent example, helical topological edge (TESs) of two-dimensional insulators and their stacked three-dimensional equivalent, weak (WTIs), have sparked research enthusiasm due to potential application in next generation electronics/spintronics with dissipation. Here, we propose layered superconducting material CaSn as WTI nontrivial ${Z}_{2}$ well nodal-line semimetal protected by crystalline...
