Hydrogen induces chiral conduction channels in the topological magnet
Afrin N. Tamanna, Ayesha Lakra, Xiaxin Ding +7
Chirality, a characteristic handedness that distinguishes 'left' from 'right', cuts widely across all of nature, from the structure of DNA to opposite chirality of particle…
Bulk band inversion and surface Dirac cones in LaSb and LaBi : Prediction of a new topological heterostructure
Urmimala Dey, Monodeep Chakraborty, A. Taraphder +1
We perform \textit{ab initio} investigations of the bulk and surface band structures of LaSb and LaBi and resolve the existing disagreements about the topological property of LaSb,…
Ginzburg-Landau theory for the conical cycloid state in multiferroics: applications to CoCrO
Chuanwei Zhang, Sumanta Tewari, John Toner +1
We show that the cycloidal magnetic order of a multiferroic can arise in the absence of spin and lattice anisotropies, for e.g., in a cubic material, and this explains the occurren…
