Relativistic Study of Motion of Photons in an Elliptical Gravitational Field [PDF]

Physics Access
Fields of elliptical objects can be considered elliptically symmetric, such that the structure, matter, and field of such an object can be defined in terms of an elliptically symmetric space metric.

Room‐Temperature Synthesis of Strongly Confined Lead Halide Perovskite Quantum Dots

Advanced Functional Materials, EarlyView.
CsPbX3${\rm CsPbX}_3$ lead halide perovskite quantum dots (QDs) are synthesized in a room‐temperature, five‐minute synthesis, yielding size‐controlled QDs with bright, tunable emission governed by reaction conditions and halide composition. A strongly binding ligand, OD‐PEA, ensures months‐long stability under ambient conditions and facilitates their ...

Superluminal noncommutative photons [PDF]

, 2001
With the help of the Seiberg–Witten map, one can obtain an effective action of a deformed QED from a noncommutative QED. Starting from the deformed QED, we investigate the propagation of photons in the background of electromagnetic field, up to the ...

Optical Signature of Moiré Superlattices Formed by Twisted SrTiO3 Membranes

Advanced Functional Materials, EarlyView.
We discover optical signatures from bonded interfaces in twisted SrTiO3 moiré superlattices, including low‐frequency Raman vibrational modes and strong second‐harmonic generation, consistent with strong interlayer coupling inferred from cross‐sectional electron microscopy and ab initio calculations. ABSTRACT Moiré superlattices formed at the interfaces

Generation and manipulation of laser beams carrying orbital angular momentum for classical and quantum information applications [PDF]

, 2009
Light orbital angular momentum (OAM) has been recognized as a new promising resource for classical and quantum information applications. In contrast to the spin angular momentum, the OAM is an inherently multidimensional.

From Photoalignment to Structured Light: Liquid Crystal Platforms for Beam Shaping and Complex Wavefronts

Advanced Functional Materials, EarlyView.
Photoaligned and photopatterned liquid crystal platforms provide programmable control of optical phase, polarization, and spin‐orbit interactions, enabling compact generation of structured light and complex wavefronts. This review highlights how tailored molecular orientations transform simple beams into designed optical fields, opening versatile ...

Non-coherent Photons Evolving to Coherent Photons in Same Classical Wave Experiments --- Photon Wave Phenomena

, 2023
We experimentally show that: in the same classical wave experiment, (1) the light is photons;  blob:https://www.techrxiv.org/2498c0ca-197a-4f4a-a278-2d1886734983 (2) near the double slit, although we assume the photons have the same frequency and phase ...

Demonstration of measurement-only blind quantum computing

New Journal of Physics, 2016
Blind quantum computing allows for secure cloud networks of quasi-classical clients and a fully fledged quantum server. Recently, a new protocol has been proposed, which requires a client to perform only measurements.
