Flash microwave pressing of zirconia [PDF]
Journal of the American Ceramic Society, Wiley, 2020, 2020 Microwave Pressing is a promising way to reduce microwave sintering temperatures and stabilize microwave powder materials processing. A multi-physics simulation was conducted of the regulated pressure-assisted microwave cavity. This simulation took into consideration resonance phenomena and the nonlinear temperature-dependent material parameters of ...

Microwave Lens for Polar Molecules [PDF]
Phys. Rev. Lett. 104, 253001 (2010), 2010 We here report on the implementation of a microwave lens for neutral polar molecules suitable to focus molecules both in low-field-seeking and in high-field-seeking states. By using the TE_11m modes of a 12 cm long cylindrically symmetric microwave resonator, Stark-decelerated ammonia molecules are transversally confined.

Low-loss high-impedance circuit for quantum transduction between optical and microwave photons [PDF]
Mater. Quantum Technol. 2 025001 (2022), 2021 Quantum transducers between microwave and optical photons are essential for long-distance quantum networks based on superconducting qubits. An optically active self-assembled quantum dot molecule (QDM) is an attractive platform for the implementation of a quantum transducer because an exciton in a QDM can be efficiently coupled to both optical and ...
