Gradient expansion approximation of the inhomogeneous electron-gas revisited: Higher-order corrections
Mario Benites, Angel Rosado, Efstratios Manousakis
In our recently published work (our Ref. 1) we revisited the gradient expansion approximation (GEA) of the interacting electron gas, and recalculated the leading-order contribution…
Twisted bilayer graphene from first-principles: structural and electronic properties
Albert Zhu, Daniel Bennett, Daniel T. Larson +3
We present a comprehensive first-principles study of twisted bilayer graphene (tBLG) for a wide range of twist angles, with a focus on structural and electronic properties. By empl…
Weyl excitonic condensation
Efstratios Manousakis
We consider a half-filled two-dimensional Su-Schrieffer-Heeger lattice and examine the role of the long-range Coulomb electron-hole attractive interaction. We demonstrate that, und…
Wavefunction textures in twisted bilayer graphene from first principles
Albert Zhu, Daniel Bennett, Daniel T. Larson +3
Motivated by recent experiments probing the wavefunctions of magic-angle twisted bilayer graphene (tBLG), we perform large-scale first-principles calculations of tBLG with full ato…
Gradient-expansion of the inhomogeneous electron-gas revisited
Mario Benites, Angel Rosado, Efstratios Manousakis
In the present work, we revisit the problem of the inhomogeneous electron gas under the influence of a weak external potential, which allows us to calculate the gradient correction…
Nonreciprocal Transport with Quantum Geometric Origin in Layered Hybrid Perovskite
Zihan Zhang, Sihan Chen, Mingfeng Chen +14
Quantum geometry quantifies how the electron wavefunction evolves distinctly from conventional transport theory. In noncentrosymmetric materials, nonreciprocal transport with quant…
