Anomalies as Obstructions: from Dimensional Lifts to Swampland
Peng Cheng, Ruben Minasian, Stefan Theisen
We revisit the relation between the anomalies in four and six dimensions and the Chern-Simons couplings one dimension below. While the dimensional reduction of chiral theories is w…
Soft black hole information paradox: Page curve from Maxwell soft hair of a black hole
Peng Cheng, Yang An
Treating Maxwell soft hair as a transition function that relates U(1) gauge fields living in the asymptotic region and near-horizon region, the U(1) gauge parameter naturally b…
Extreme Suppression of Antiferromagnetic Order and Critical Scaling in a Two-Dimensional Random Quantum Magnet
Wenshan Hong, Lu Liu, Chang Liu +16
SrCuTeO is a square-lattice Néel antiferromagnet with superexchange between first-neighbor Cu spins mediated by plaquette centered Te ions. Substituting Te by W, th…
Realize Emergent Gravity to Generic Situations
Yang An, Peng Cheng
We clarify the problem in which occasions can gravitational force be regarded emergent from thermodynamics, by proposing an entropic mechanism that can extract the entropic gradien…
Quantum oscillations and electronic structure in the large-Chern number topological chiral semimetal PtGa
Sheng Xu, Liqin Zhou, Xiao-Yan Wang +6
We report the magnetoresistance(MR), de Haas-van Alphen (dHvA) oscillations and the electronic structures of single crystal PtGa. The large unsaturated MR is observed with the magn…
Tunable magnetic properties in van der Waals crystals (FeCo)GeTe
Congkuan Tian, Feihao Pan, Sheng Xu +3
We report the doping effects of cobalt on van der Waals (vdW) magnet FeGeTe. A series of (FeCo)GeTe (0x0.44) single crystals have been succe…
