Spatiotemporal Fourier transform with femtosecond pulses for on-chip devices

open access: yesOpto-Electronic Advances, 2022
On-chip manipulation of the spatiotemporal characteristics of optical signals is important in the transmission and processing of information. However, the simultaneous modulation of on-chip optical pulses, both spatially at the nano-scale and temporally ...

The Green Function for the BFKL Pomeron and the Transition to DGLAP Evolution [PDF]

open access: yes, 2014
We consider the (process-independent) Green function for the BFKL equation in the next-to-leading order approximation, with running coupling, and explain how, within the semi-classical approximation, it is related to Green function of the Airy equation ...

Skimmia anquetilia N.P. Taylor and Airy Shaw (Rutaceae): A Critical Appriasal of its Ethnobotanical and Pharmacological Activities

open access: yesFrontiers in Plant Science, 2022
Skimmia anquetilia N.P. Taylor and Airy Shaw (Rutaceae) is a perennial, aromatic, gregarious wild ornamental shrub native to the Western Himalaya. The plant is used in the traditional medicinal system to treat copious health conditions like rheumatism ...

Observation of accelerating parabolic beams [PDF]

open access: yes, 2008
We report the first observation of accelerating parabolic beams. These accelerating parabolic beams are similar to the Airy beams because they exhibit the unusual ability to remain diffraction-free while having a quadratic transverse shift during ...

Generalised photon sieves: fine control of complex fields with simple pinhole arrays [PDF]

open access: yes, 2015
Spatial shaping of light beams has led to numerous new applications in fields such as imaging, optical communication, and micromanipulation. However, structured radiation is less well explored beyond visible optics, where methods for shaping fields are ...

Phytochemical screening and antibacterial activity of Skimmia anquetilia N.P. Taylor and Airy Shaw: A first study from Kashmir Himalaya

open access: yesFrontiers in Plant Science, 2022
The present study aimed to explore the antibacterial activity of various organic root extracts of Skimmia anquetilia N.P. Taylor and Airy Shaw and the identification of major functional groups and phytoconstituents through fourier transform infrared ...

Gaussian and Airy wave packets of massive particles with orbital angular momentum [PDF]

open access: yes, 2015
While wave-packet solutions for relativistic wave equations are oftentimes thought to be approximate (paraxial), we demonstrate that there is a family of such solutions, which are exact, by employing a null-plane (light-cone) variables formalism.

Analyticity of extremisers to the Airy Strichartz inequality

open access: yes, 2010
We prove that there exists an extremal function to the Airy Strichartz inequality, $e^{-t\partial_x^3}: L^2(\mathbb{R})\to L^8_{t,x}(\mathbb{R}^2)$ by using the linear profile decomposition.

Narain transform for spectral deformations of random matrix models

open access: yesNuclear Physics B, 2020
We start from applying the general idea of spectral projection (suggested by Olshanski and Borodin and advocated by Tao) to the complex Wishart model. Combining the ideas of spectral projection with the insights from quantum mechanics, we derive in an ...
