Incommensurate heterostructures in momentum space [PDF]

, 2017
To make the investigation of electronic structure of incommensurate heterostructures computationally tractable, effective alternatives to Bloch theory must be developed. In [Multiscale Model. Simul., 15(2017), pp.

Enhanced colloidal transport in twisted magnetic patterns [PDF]

, 2022
Bilayers of two-dimensional materials twisted at specific angles can exhibit exceptional properties such as the occurrence of unconventional superconductivity in twisted graphene. We demonstrate here that novel phenomena in twisted materials emerges also

Strain Engineering of Twisted Bilayer Graphene: The Rise of Strain-Twistronics. [PDF]

Small
Abstract The layer‐by‐layer stacked van der Waals structures (termed vdW hetero/homostructures) offer a new paradigm for materials design—their physical properties can be tuned by the vertical stacking sequence as well as by adding a mechanical twist, stretch, and hydrostatic pressure to the atomic structure.

Bulk valley transport and Berry curvature spreading at the edge of flat bands

, 2020
2D materials based superlattices have emerged as a promising platform to modulate band structure and its symmetries. In particular, moir\'e periodicity in twisted graphene systems produces flat Chern bands. The recent observation of anomalous Hall effect

Twistronics of Janus transition metal dichalcogenide bilayers

Physical Review B, 2022
Twisted multilayers of two-dimensional (2D) materials are an increasingly important platform for investigating quantum phases of matter, and in particular, strongly correlated electrons. The moiré pattern introduced by the relative twist between layers creates effective potentials of long-wavelength, leading to electron localization.
