Investigation of underwater quantum channels in a 30 meter flume tank using structured photons

New Journal of Physics, 2020
Underwater quantum communication has recently been explored using polarization and orbital angular momentum (OAM). Here, we show that spatially structured modes, e.g., a coherent superposition of beams carrying both polarization and OAM, can also be used

Polarization superposition of room-temperature polariton condensation

Communications Materials, 2023
A methodology for forming a qubit state is essential for quantum applications of room temperature polaritons. While polarization degree of freedom is expected as a possible means for this purpose, the coupling of linearly polarized polariton condensed ...

Polarization degrees of freedom in photoinduced two-nucleon knockout from finite nuclei [PDF]

Physical Review C, 1998
The polarization degrees of freedom in photoinduced two-nucleon knockout from finite nuclei are studied. It is pointed out that they open good perspectives to study the dynamics of dinucleons in the medium in detail. The ($γ,pp$) and ($γ,pn$) angular cross sections, photon asymmetries and outgoing nucleon polarizations are calculated for the target ...

Exceptional Electro‐Optic Coefficient Unlocked via Polarization Swaying in KNbO3 Thin Films

Advanced Functional Materials, EarlyView.
We present the largest reported electro‐optic response in any material to date, guided by a new design principle that exploits ultralow coercive field polarization swaying enabled by low‐symmetry ferroelectric phases in monoclinic KNbO3 thin films for energy‐efficient classical and quantum photonic integrated circuits. ABSTRACT The electro‐optic effect

All photons are equal but some photons are more equal than others

New Journal of Physics, 2012
Two photons are said to be identical if they are prepared in the same quantum state. Given the latter, there is a unique way to achieve this. Conversely, there are many different ways of preparing two non-identical photons: they may differ in frequency ...

Measurements of global and local spin polarization of hyperons in Au+Au collisions at RHIC-STAR [PDF]

EPJ Web of Conferences
Vortical structure created in heavy ion collision leads to the polarization of hyperons phenomenon, which can be used as a probe to study the spin degree of freedom.

Scalable Fabrication of Thermally Reconfigurable Ge Metasurfaces Using Stencil Lithography for Mid‐Infrared Molecular Fingerprinting

Advanced Functional Materials, EarlyView.
Scalable stencil lithography enables resist‐free fabrication of high‐index Ge metasurfaces for mid‐infrared molecular fingerprinting. Reversible thermo‐optic tuning provides post‐fabrication spectral control for precise resonance–vibration mode alignment, enabling enhanced molecular fingerprinting of microplastic particles.

Single‐Cell Resolution Mapping of Osteoarthritis‐Associated Chondrocyte Dynamics Using a High‐Density CMOS MEA Platform

Advanced Healthcare Materials, EarlyView.
Single‐cell and spatially resolved impedance mapping using a high‐density CMOS‐MEA platform enables non‐invasive monitoring of osteoarthritis‐associated chondrocyte dynamics. Continuous label‐free measurements reveal heterogeneous remodeling behaviors, including proliferation, migration, and phenotypic transitions, establishing a powerful approach for ...
