Spontaneous Twirls and Structural Frustration in Moiré Materials
Jingtian Shi, Gaurav Chaudhary, Allan H. MacDonald +1
Structural twirls form spontaneously in the domain wall networks of some moiré materials. We show that in heterobilayers, neighboring twirl chiralities tend to anti-align, forming…
Superconductivity from polar fluctuations in multi-orbital systems
Gaurav Chaudhary, Ivar Martin
Motivated by the superconductivity near paraelectric (PE) to ferroelectric (FE) quantum critical point (QCP) in polar metals, we study polar fluctuation mediated superconductivity…
Quantum Hall Superconductivity from Moir{é} Landau Levels
Gaurav Chaudhary, A. H. MacDonald, M. R. Norman
It has long been speculated that quasi-two-dimensional superconductivity can reappear above its semiclassical upper critical field due to Landau quantization, yet this reentrant pr…
Multiple Flat Bands and Topological Hofstadter Butterfly in Twisted Bilayer Graphene Close to the Second Magic Angle
Xiaobo Lu, Biao Lian, Gaurav Chaudhary +8
Moiré superlattices in two-dimensional (2D) van der Waals (vdW) heterostructures provide 20 an efficient way to engineer electron band properties. The recent discovery of exotic qu…
Phonon-mediated dimensional crossover in bilayer CrI3
M. Rodriguez-Vega, Ze-Xun Lin, A. Leonardo +4
In bilayer CrI3, experimental and theoretical studies suggest that the magnetic order is closely related to the layer staking configuration. In this work, we study the effect of dy…
Anatomy of magnetic anisotropy induced by Rashba spin-orbit interactions
Gaurav Chaudhary, Manuel dos Santos Dias, Allan H. MacDonald +1
Magnetic anisotropy controls the orientational stability and switching properties of magnetic states, and therefore plays a central role in spintronics. First-principles density-fu…
The Quantum Anomalous Hall Majorana Platform
Yongxin Zeng, Chao Lei, Gaurav Chaudhary +1
We show that quasi-one-dimensional (1D) quantum wires can be written onto the surface of magnetic topological insulator (MTI) thin films by gate arrays. When the MTI is in a quantu…
