On-chip Cherenkov radiation tuning in 3.2-14 THz
Design and fabrication
The proposed on-chip free-electron THz source is sketched in Fig. 1a. The HMM in the THz frequency region is constructed by alternating graphene and hBN layers (see Supplementary Information Section S1). On the two sides…

Spatial-mode diversity and multiplexing for continuous variables quantum communications
We analyze a single diversity-based communication scheme under three distinct amplification strategies, each corresponding to different assumptions about channel state information (CSI) available at the transmitter or receiver. In the context of…

An approach using geometric diagrams to generic Bell inequalities with multiple observables
Local hidden variables (LHVs) theories assume that the measurement outcomes are predetermined prior to actual measurement, with physical influences propagating no faster than the speed of light. Within this framework, the LHVs theories…

Computational modeling of surface energy effects on linear and nonlinear frequencies in different crystalline orientations of anodic aluminum micro-beams
The micro beam is resting on an elastic foundation, which provides distributed support and influences its mechanical response. This model is fundamental for analyzing the dynamic and static response of microscale structures, particularly in…

Combined isochoric processes of freezing and supercooling
The isochoric freezing and isochoric supercooling process proceeds as follows: As the isochoric chamber is cooled below the freezing temperature of pure water, ice begins to form in the external aqueous phase, which surrounds the compartment…

Scientists Build Scalable Network Node With Light and Ions
One by one, each ion-qubit is moved into an optical cavity, where mirrors efficiently collect the photons emitted by the ion-qubit. Each photon emerges entangled with its ion-qubit, forming a deep quantum link. Credit: Universität… Continue Reading

Tiny reactor boosts fusion with a sponge-like trick
Using a small bench-top reactor, researchers at the University of British Columbia (UBC) have demonstrated that electrochemically loading a solid metal target with deuterium fuel can boost nuclear fusion rates.
Large-scale magnetic confinement…
