Universal Multifractality at the Topological Anderson Insulator Transition
Ksenija Kovalenka, Ahmad Ranjbar, Sam Azadi +3
Disorder is ubiquitous in quantum materials, and its interplay with topology can generate phases absent in the clean limit. Using the Haldane model as a minimal setting, we show th…
Designer three-dimensional electronic bands in asymmetric transition metal dichalcogenide heterostructures
Oliver J. Clark, Anugrah Azhar, Ben A. Chambers +15
Van der Waals materials enable the construction of atomically sharp interfaces between compounds with distinct crystal and electronic properties. This is dramatically exploited in…
Quantum Monte Carlo description of correlated electrons in two-dimensional FeSe
S. Azadi, A. Principi, R. V. Belosludov +2
An interesting question in physics is how the correlation energy of atoms evolves upon forming a solid. Here, we address this problem for a specific case of double-layer FeSe. We u…
Resonant interlayer coupling in NbSe-graphite epitaxial moir{é} superlattices
S. Mo, K. Kovalenka, S. Buchberger +9
Moir{é} heterostructures, created by stacking two-dimensional (2D) materials together with a finite lattice mismatch or rotational twist, represent a new frontier of designer quan…
Elastic properties of transition metal dichalcogenides
S. Azadi, A. Azhar, R. V. Belosludov +2
We present a comprehensive first-principles study of the structural and elastic properties of 2H-MX transition metal dichalcogenides (TMDs) (M = W, Mo, Ta, Nb; X = S, Se). Usin…
Quantum Monte Carlo study of the quasiparticle effective mass of the two-dimensional uniform electron liquid
S. Azadi, N. D. Drummond, A. Principi +2
The real-space variation quantum Monte Carlo (VMC) and diffusion quantum Monte Carlo (DMC) are used to calculate the quasiparticle energy bands and the quasiparticle effective mass…
