Electron correlation in semiconductors and insulators via symbolic regression
Nick Pant, Viet-Anh Ha, Donghwan Kim +1
Predicting quasiparticle energies in materials requires expensive numerical evaluations of the electron self-energy. This limits calculations to ordered systems with small unit cel…
Collective quantum state at the atomic limit
Fan Zhang, Yanxing Li, Chengye Dong +8
Collective quantum states are often associated with extended systems, where spatially extensive degrees of freedom enable emergent many-body behavior; whether such strongly correla…
Meta-optimization of maximally-localized Wannier functions
Sabyasachi Tiwari, Bruno Cucco, Viet-Anh Ha +1
Maximally-localized Wannier functions are quantum wavefunctions resembling atomic orbitals that are used to describe electrons in condensed matter. Since their introduction in 1997…
High-throughput screening of 2D materials identifies p-type monolayer WS as potential ultra-high mobility semiconductor
Viet-Anh Ha, Feliciano Giustino
2D semiconductors offer a promising pathway to replace silicon in next-generation electronics. Among their many advantages, 2D materials possess atomically-sharp surfaces and enabl…
Robust Super-Moiré in Large Angle Single-Twist Bilayers
Yanxing Li, Chuqiao Shi, Fan Zhang +19
Forming long wavelength moiré superlattices (MSL) at small-angle twist van der Waals (vdW) bilayers has been a key approach to creating moiré flat bands. The small-angle twist, h…
Intrinsic Limits of Charge Carrier Mobilities in Layered Halide Perovskites
Bruno Cucco, Joshua Leveillee, Viet-Anh Ha +4
Layered halide perovskites have emerged as potential alternatives to three-dimensional halide perovskites due to their improved stability and larger material phase space, allowing…
