Moir\'e engineering in atomically thin van der Waals heterostructures creates artificial quantum materials with designer properties.

Topogivity: A Machine-Learned Chemical Rule for Discovering Topological Materials

1 code implementation10 Feb 2022 Andrew Ma, Yang Zhang, Thomas Christensen, Hoi Chun Po, Li Jing, Liang Fu, Marin Soljačić

Topological materials present unconventional electronic properties that make them attractive for both basic science and next-generation technological applications.

Quantum frequency doubling in the topological insulator Bi2Se3

no code implementations24 Dec 2020 Pan He, Hiroki Isobe, Dapeng Zhu, Chuang-Han Hsu, Liang Fu, Hyunsoo Yang

We introduce the Berry curvature triple, a high-order moment of the Berry curvature, to explain skew scattering under the threefold rotational symmetry.

New mechanism and exact theory of superconductivity from strong repulsive interaction

no code implementations15 Dec 2020 Valentin Crépel, Liang Fu

We introduce a new and general mechanism for superconductivity in Fermi systems with strong repulsive interaction.

Topological metals and finite-momentum superconductors

no code implementations8 Sep 2020 Noah F. Q. Yuan, Liang Fu

We show that Zeeman field can induce a topological transition in two-dimensional spin-orbit coupled metals, and concomitantly, a first-order phase transition in the superconducting state involving a discontinuous change of Cooper pair momentum.

A new Majorana platform in an Fe-As bilayer superconductor

no code implementations1 Jul 2019 Wenyao Liu, Lu Cao, Shiyu Zhu, Lingyuan Kong, Guangwei Wang, Michal Papaj, Peng Zhang, Yabin Liu, Hui Chen, Geng Li, Fazhi Yang, Takeshi Kondo, Shixuan Du, Guanghan Cao, Shik Shin, Liang Fu, Zhiping Yin, Hong-Jun Gao, Hong Ding

On the other hand, some iron-pnictide (Fe-As) superconductors, such as LiFeAs, have been demonstrated to have a similar topological band structure, yet no MZM has been observed in its vortex cores, raising a question of universality of MZM presence in iron-based superconductors.
