Chirality-induced Phonon-Spin Conversion at an Interface

Kavli Affiliate: Mamoru Matsuo | First 5 Authors: Takumi Funato, Mamoru Matsuo, Takeo Kato, , | Summary: We consider spin injection driven by nonequilibrium chiral phonons from a chiral insulator into an adjacent metal. Phonon-spin conversion arises from the coupling of the electron spin with the microrotation associated with chiral phonons. We derive a microscopic […]

Exciton-phonon coupling induces new pathway for ultrafast intralayer-to-interlayer exciton transition and interlayer charge transfer in WS2-MoS2 heterostructure: a first-principles study

Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: Yang-hao Chan, Mit H. Naik, Jonah B. Haber, Jeffrey B. Neaton, Steven G. Louie | Summary: Despite the weak, van-der-Waals interlayer coupling, photoinduced charge transfer vertically across atomically thin interfaces can occur within surprisingly fast, sub-50fs timescales. Early theoretical understanding of the charge transfer is based […]

SWEA: Changing Factual Knowledge in Large Language Models via Subject Word Embedding Altering

Kavli Affiliate: Jing Wang | First 5 Authors: Xiaopeng Li, Shasha Li, Bin Ji, Shezheng Song, Xi Wang | Summary: Model editing has recently gained widespread attention. Current model editing methods primarily involve modifying model parameters or adding additional modules to the existing model. However, the former causes irreversible damage to LLMs, while the latter […]
