Perfect Coulomb drag in a dipolar excitonic insulator

Kavli Affiliate: Jie Shan | First 5 Authors: Phuong X. Nguyen, Liguo Ma, Raghav Chaturvedi, Kenji Watanabe, Takashi Taniguchi | Summary: Excitonic insulators (EIs), arising in semiconductors when the electron-hole binding energy exceeds the band gap, are a solid-state prototype for bosonic phases of matter. Unlike the charged excitations that are frozen and unable to […]

Multiferroic Magnon Spin-Torque Based Reconfigurable Logic-In-Memory

Kavli Affiliate: Daniel C. Ralph | First 5 Authors: Yahong Chai, Yuhan Liang, Cancheng Xiao, Yue Wang, Bo Li | Summary: Magnons, bosonic quasiparticles carrying angular momentum, can flow through insulators for information transmission with minimal power dissipation. However, it remains challenging to develop a magnon-based logic due to the lack of efficient electrical manipulation […]
