Low-Field Metal-Insulator Transition in AB-Stacked Bilayer Graphene
Amarnath Chakraborty, Aleksandr Rodin, Shaffique Adam +1
We investigate the interplay of in-plane magnetic and transverse electric fields in AB-stacked bilayer graphene. In prior work neglecting trigonal warping, we demonstrated that thi…
Altermagnetism, Kagome Flat Band, and Weyl Fermion States in Magnetically Intercalated Transition Metal Dichalcogenides
Avinash Sah, Ting-Yong Lim, Clayton Conner +5
Altermagnetic (AM) compounds have recently emerged as a promising platform for realizing unconventional quantum phases, enabled by their unique spin-split band structure at zero ne…
Insulator-Metal Transition and Magnetic Crossover in Bilayer Graphene
Amarnath Chakraborty, Aleksandr Rodin, Shaffique Adam +1
In-plane magnetic fields offer a relatively unexplored opportunity to alter the band structure of stacks of 2D materials so that they exhibit desired physical properties. Here we s…
Observation of 2D Weyl Fermion States in Epitaxial Bismuthene
Qiangsheng Lu, P. V. Sreenivasa Reddy, Hoyeon Jeon +20
A two-dimensional (2D) Weyl semimetal featuring a spin-polarized linear band dispersion and a nodal Fermi surface is a new topological phase of matter. It is a solid-state realizat…
Photon Absorption of Two-dimensional Nonsymmorphic Dirac Semimetals
Amarnath Chakraborty, Guang Bian, Giovanni Vignale
Two-dimensional Dirac semimetals have attracted much attention because of their linear energy dispersion and non-trivial Berry phase. Graphene-like 2D Dirac materials are gapless o…
