Bidirectional microwave-optical transduction based on integration of high-overtone bulk acoustic resonators and photonic circuits

Tobias Kippenberg, Rui Ning Wang, Anat Siddharth, Terence Albert Emile Blésin, Wil Kao

Coherent interconversion between microwave and optical frequencies can serve as both classical and quantum interfaces for computing, communication, and sensing. Here, we present a compact microwave-optical transducer based on monolithic integration of piez ...

Three-Dimensional Confinement of Water: H2O Exhibits Long-Range (> 50 nm) Structure while D2O Does Not

Sylvie Roke, Nathan Dupertuis, Cornelis Ulrich Lütgebaucks, Orly Bagunu Tarun

Water is the liquid of life thanks to its three-dimensional adaptive hydrogen (H)-bond network. Confinement of this network may lead to dramatic structural changes influencing chemical and physical transformations. Although confinement effects occur on a < ...

Attosecond coherent electron motion in Auger-Meitner decay

Christoph Bostedt

In quantum systems, coherent superpositions of electronic states evolve on ultrafast time scales (few femtoseconds to attoseconds; 1 attosecond = 0.001 femtoseconds = 10(-18) seconds), leading to a time-dependent charge density. Here we performed time-reso ...

Evidence on the effects of main-chamber neutrals on density shoulder broadening

Basil Duval, Nicola Vianello, Holger Reimerdes, Christian Gabriel Theiler, Umar Sheikh, Cedric Kar-Wai Tsui, Mirko Wensing, Marcelo Baquero Ruiz, Artur Perek, Sophie Danielle Angelica Gorno

Evidence that density shoulder broadening is dependent on high main-chamber neutral density is presented. Shoulder broadening does notoccur when the sources for main-chamber neutrals are minimized using divertor baffles and wide gaps to the first wall (sim ...
