Geometric control of the moire twist angle in heterobilayer flakes
Prathap Kumar Jharapla, Nicolas Leconte, Zhiren He +2
We demonstrate a finite twist-angle stabilization mechanism in lattice-mismatched 2D heterobilayers, which results from the geometric alignment between the flake edges and its moir…
Lattice-induced spin dynamics in Dirac magnet CoTiO3
Andrey Baydin, Jiaming Luo, Zhiren He +8
Spin-lattice coupling is crucial for understanding the spin transport and dynamics for spintronics and magnonics applications. Recently, cobalt titanate (CoTiO3), an easy-plane ant…
Persistent spin textures, altermagnetism and charge-to-spin conversion in metallic chiral crystals TMX
Karma Tenzin, Berkay Kilic, Raghottam Sattigeri +6
Chiral crystals, due to the lack of inversion and mirror symmetries, exhibit unique spin responses to external fields, enabling physical effects rarely observed in high-symmetry sy…
Optical control of the moiré twist angle
Zhiren He, Prathap Kumar Jharapla, Nicolas Leconte +2
In this theoretical work, we propose an all-optical method for fast, precise manipulation of two-dimensional multilayers by transferring orbital angular momentum from phase-structu…
Optical Control of Ferroaxial Order
Zhiren He, Guru Khalsa
Materials that exhibit ferroaxial order hold potential for novel multiferroic applications. However, in pure ferroaxials, domains are not directly coupled to stress or static elect…
