Photogalvanic effect in few layer graphene
Zhaohang Li, Kainan Chang, Haoyu Li +4
We systematically investigate the nonlinear photogalvanic effect in few-layer graphene with various stacking orders, including AA- and AB-stacked bilayers, and AAA-, ABA-, and ABC-…
GKP-inspired high-dimensional superdense coding with energy-time entanglement
Kai-Chi Chang, Arjun Mirani, Murat Can Sarihan +4
Superdense coding, the application of entanglement to boost classical communication capacity, is a cornerstone of quantum communication. In this paper, we propose a high-dimensiona…
Ultralong Octupole Moment Switching Driven by Twin Topological Spin
Shijie Xu, Zhizhong Zhang, Yan Huang +10
Spintronics has emerged as a revolutionary frontier in the pursuit of faster, more energy-efficient, and technologically advanced electronics.
Non-Abelian gauge field optics in the time domain
Yucheng Lai, Yongliang Zhang, Kai Chang
Artificial gauge fields open up burgeoning opportunities for wave engineering in different disciplines. So far,previous works have mostly focused on synthesizing spatial gauge fiel…
Quantized Quadrupole Superconductors
Yun-Mei Li, Yongwei Huang, Kai Chang
We introduce a class of superconductors termed "quantized quadrupole superconductors" that support Majorana corner modes according to the bulk-corner correspondence, distinct from…
Incommensurate-Stabilized Fractional Chern Insulator in Alternating Twisted Trilayer Graphene
Moru Song, Kai Chang
Fractional Chern insulators (FCIs) typically emerge in topological flat bands and are regarded as lattice analogs of fractional quantum Hall states. Conventionally, the flat-band w…
