Mid-infrared single-pixel imaging at the single-photon level

Nature Communications, 2023
The authors present an implementation of mid-infrared single-photon computational imaging with a single-element silicon detector. In addition to unique features of single-pixel simplicity and room-temperature operation, the infrared imager offers a ...

Focus image scanning microscopy for sharp and gentle super-resolved microscopy

Nature Communications, 2022
Super-resolution microscopy techniques can be challenging for live cells and thick samples. Here, the authors propose a method to reduce beam intensity and remove out-of-focus fluorescence background in image-scanning microscopy (ISM) and its combination

Exotics and all that

, 2003
This invited contribution summarizes some of the more important aspects of exotics. We review theoretical expectations for exotic and nonexotic hybrid mesons, and briefly discuss the leading experimental candidate for an exotic, the pi_1(1600).Comment: 4

ABJM Dibaryon Spectroscopy [PDF]

, 2011
We extend the proposal for a detailed map between wrapped D-branes in Anti-de Sitter space and baryon-like operators in the associated dual conformal field theory provided in hep-th/0202150 to the recently formulated AdS_4 \times CP^3/ABJM correspondence.

Quantifying defects in graphene via Raman spectroscopy at different excitation energies. [PDF]

Nano letters (Print), 2011
We present a Raman study of Ar(+)-bombarded graphene samples with increasing ion doses. This allows us to have a controlled, increasing, amount of defects.

Spectroscopy

Fusion Science and Technology, 2004
A brief introduction into the spectroscopy of fusion plasmas is presented. Basic principles of the emission of ionic, atomic and molecular radiation will be explained and a survey of the effects, which lead to the population of the respective excited levels, will be given.

Dark Spectroscopy

, 2017
Rich and complex dark sectors are abundant in particle physics theories. Here we propose performing spectroscopy of the mass structure of dark sectors via mono-photon searches at lepton colliders.

Colloquium: Graphene spectroscopy [PDF]

, 2014
Spectroscopic studies of electronic phenomena in graphene are reviewed. A variety of methods and techniques are surveyed, from quasiparticle spectroscopies (tunneling, photoemission) to methods probing density and current response (infrared optics, Raman)

Astronomical Spectroscopy

, 2011
Spectroscopy is one of the most important tools that an astronomer has for studying the universe. This chapter begins by discussing the basics, including the different types of optical spectrographs, with extension to the ultraviolet and the near ...
