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…
Physical spin torques from exactly constrained exchange-correlation torques
Jacques K. Desmarais, Kamel Bencheikh, Giovanni Vignale +1
The problem of capturing physical spin torques in non-collinear magnetic systems has dominated the scene of spin-density functional theory (SDFT) in the last two decades. Progress…
Many-body perturbation theory for moiré systems
Liangtao Peng, Giovanni Vignale, Shaffique Adam
Moiré systems such as magic-angle twisted bilayer graphene have attracted significant attention due to their ability to host correlated phenomena including superconductivity and st…
Meta-Generalized-Gradient Approximation made Magnetic
Jacques K. Desmarais, Alessandro Erba, Giovanni Vignale +1
The Jacob's ladder of density functional theory (DFT) proposes the compelling view that by extending the form of successful approximations -- being guided by exact conditions and s…
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…
Electron localization function for non-collinear spins
Jacques K. Desmarais, Giovanni Vignale, Kamel Bencheikh +2
Understanding of bonding is key to modelling materials and predicting properties thereof. A widely adopted indicator of bonds and atomic shells is the electron localization functio…
Observability of cyclotron resonance in the hydrodynamic regime of bilayer graphene
Joseph R. Cruise, Alexander Seidel, Erik Henriksen +1
We offer theoretical predictions for the frequency of the resonant frequency of transport for the hydrodynamic description of bilayer graphene, as well as provide quantification fo…
Spin-currents via the gauge-principle for meta-generalized-gradient exchange-correlation functionals
Jacques K. Desmarais, Jefferson Maul, Bartolomeo Civalleri +3
The prominence of density functional theory (DFT) in the field of electronic structure computation stems from its ability to usefully balance accuracy and computational effort. At…
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…
Transverse and longitudinal gradients of the spin magnetization in Spin-Density-Functional Theory
F. G. Eich, S. Pittalis, G. Vignale
We derive the gradient expansion for the exchange energy of a spin-polarized electron gas by perturbing the uniformly spin polarized state and thus inducing a small non-collinearit…
Quantum continuum mechanics in a strong magnetic field
S. Pittalis, G. Vignale, I. V. Tokatly
We extend a recent formulation of quantum continuum mechanics [J. Tao et. al, Phys. Rev. Lett. {\bf 103}, 086401 (2009)] to many-body systems subjected to a magnetic field. To acco…
