Exponentially Enhanced non-Hermitian Cooling
Haowei Xu, Uroš Delić, Guoqing Wang +3
Certain non-Hermitian systems exhibit the skin effect, whereby the wavefunctions become exponentially localized at one edge of the system. Such exponential amplification of wavefun…
Two-photon Interface of Nuclear Spins Based on the Opto-Nuclear Quadrupolar Effect
Haowei Xu, Changhao Li, Guoqing Wang +5
Photons and nuclear spins are two well-known building blocks in quantum information science and technology. Establishing an efficient interface between optical photons and nuclear…
Laser Cooling of Nuclear Magnons
Haowei Xu, Guoqing Wang, Changhao Li +5
The initialization of nuclear spin to its ground state is challenging due to its small energy scale compared with thermal energy, even at cryogenic temperature. In this Letter, we…
