环球深观察丨美国“极限施压”这四年：没让伊朗屈服，却将自己变成孤家寡人
来源：环球资讯+ 伊朗政府发言人拉比耶当地时间19日表示，伊方希望伊核协议继续存在，但“除非确信美国不加任何先决条件地恢复遵守协议，否则双方的接触将毫无意义”。针对此前以色列媒体有关美国新政府已为重返伊核协议与伊朗进行秘密对话的报道，拉比耶澄清说，伊方从未与拜登团队有过此类接触。

Coherent upconversion of terahertz and mid-infrared signals into visible light opens new horizons for spectroscopy， imaging， and sensing but represents a challenge for conventional nonlinear optics. Here， we used a plasmonic nanocavity hosting a few hundred molecules to demonstrate optomechanical transduction of submicrowatt continuous-wave signals from the mid-infrared onto the visible domain at ambient conditions. The incoming field resonantly drives a collective molecular vibration， which imprints a coherent modulation on a visible pump laser and results in upconverted Raman sidebands with subnatural linewidth. Our dual-band nanocavity offers an estimated 13 orders of magnitude enhancement in upconversion efficiency per molecule. Our results demonstrate that molecular cavity optomechanics is a flexible paradigm for frequency conversion leveraging tailorable molecular and plasmonic properties.
