Frontiers in Optics 2014, 2014 We report the implementation of a tunable beam displacer, composed of a polarizing beam splitter (PBS) and two mirrors, that divides an initially polarized beam into two parallel beams whose separation can be continuously tuned.

Tunable axion plasma haloscopes [PDF]
Physical Review Letters, 2019 We propose a new strategy to search for dark matter axions using tunable cryogenic plasmas. Unlike current experiments, which repair the mismatch between axion and photon masses by breaking translational invariance (cavity and dielectric haloscopes), a ...

Tunable Nanoplasmonic Photodetectors
Nano Letters, 2022 Visible and infrared photons can be detected with a broadband response via the internal photoeffect. By using plasmonic nanostructures, i.e. nanoantennas, wavelength selectivity can be introduced to such detectors through geometry-dependent resonances.

Acta Crystallographica Section A Foundations of Crystallography, 2001 Investigation of the selectivity of a diol organic host for mixtures of DMF and DMSO, showed the formation of five inclusion compounds in which the stoichiometry varies in discrete steps and is determined by the composition of the liquid guest mixture; the structures of these compounds are described.

Spin-Polarized Tunable Photocurrents [PDF]
Nano Letters, 2021 Harnessing the unique features of topological materials for the development of a new generation of topological based devices is a challenge of paramount importance. Using Floquet scattering theory combined with atomistic models we study the interplay between laser illumination, spin and topology in a two-dimensional material with spin-orbit coupling ...

Tunable graphene phononic crystal [PDF]
Nano Letters, 2020 Abstract In the field of phononics, periodic patterning controls vibrations and thereby the flow of heat and sound in matter. Bandgaps arising in such phononic crystals realize low-dissipation vibrational modes and enable applications towards mechanical qubits, efficient waveguides, and state-of-the-art sensing.

Tunable microfluidic microlenses [PDF]
Applied Optics, 2005 A novel type of liquid microlens, bounded by a microfabricated, distensible membrane and activated by a microfluidic liquid-handling system, is presented. By use of an elastomer membrane fabricated by spin coating onto a dry-etched silicon substrate, the liquid-filled cavity acts as a lens whereby applied pressure changes the membrane distension and ...

Jamming with Tunable Roughness [PDF]
Physical Review Letters, 2020 We introduce a new model to study the effect of surface roughness on the jamming transition. By performing numerical simulations, we show that for a smooth surface, the jamming transition density and the contact number at the transition point both increase upon increasing asphericity, as for ellipsoids and spherocylinders.

Demonstration of multi-pass amplification of 46.9 nm laser pumped by capillary discharge
Matter and Radiation at Extremes, 2023 Using a plane–plane resonator composed of silicon carbide mirrors, we achieve for the first time multi-pass amplification of a 46.9 nm laser pumped by capillary discharge.
