An Ergodic Theory of Binary Operations-Part II: Applications to Polarization

An open problem in polarization theory is to determine the binary operations that always lead to polarization (in the general multilevel sense) when they are used in Arikan style constructions. This paper, which is presented in two parts, solves this probl ...

Microscopic Origin of the Valley Hall Effect in Transition Metal Dichalcogenides Revealed by Wavelength-Dependent Mapping

Helmuth Berger

The band structure of many semiconducting monolayer transition metal dichalcogenides (TMDs) possesses two degenerate valleys with equal and opposite Berry curvature. It has been predicted that, when illuminated with circularly polarized light, interband tr ...

Multifunctional Plasmonic Metasurfaces for Novel Spectral and Spatial Applications

Chen Yan

Intensive developments of plasmonic nanomaterials over recent decades have inspired appealing applications in biosensing, optical trapping, fluorescence enhancement and light harvesting in solar cells. These nanostructures supporting unique light-matter in ...

Temperature-colour interaction: is colour affecting people’s thermal perception?

Marilyne Andersen, Jan Wienold, Giorgia Chinazzo

Over the last century, a large number of studies has tried to answer to the question whether coloured stimuli could have an effect on human thermal perceptual evaluation (i.e., temperature-colour interaction). In the building research area, this effect is ...

Exchange anisotropy in the skyrmion host GaV4S8

Dirk Grundler

Using ferromagnetic resonance spectroscopy at 34 GHz we explored the magnetic anisotropy of single-crystalline GaV4S8 in the field-polarized magnetic state. We describe the data in terms of an easy-axis type uniaxial anisotropy with an anisotropy constant ...

3D-Printed Beam Splitter for Polar Neutral Molecules

Andreas Osterwalder, Sean Dennis Steven Gordon

We describe a macroscopic beam splitter for polar neutral molecules. A complex electrode structure is required for the beam splitter which would be very difficult to produce with traditional manufacturing methods. Instead, we make use of a nascent manufact ...

Fourier transform spectroscopy in the vibrational fingerprint region with a birefringent interferometer

Christoph Peter Hauri

We introduce a birefringent interferometer for Fourier transform (FT) spectroscopy in the mid-infrared, covering the vibrational fingerprint region (5-10 µm, 1000-2000 cm-1), which is crucial for molecular identification. Our interferometer empl ...

Circularly Polarized Compact LTSA Array in SIW Technology

Juan Ramon Mosig, Marc Esquius Morote, Lei Wang

Typical linearly tapered slot antenna (LTSA) usually features a wideband and a high gain. However, its geometry size is large, especially very long in the tapering direction, which limits its application in compact antenna and array systems. This communica ...

Near optimal graphene terahertz non-reciprocal isolator

Juan Ramon Mosig, Mihai Adrian Ionescu, Clara-Fausta Moldovan, Julien Perruisseau-Carrier, Michele Tamagnone

Isolators, or optical diodes, are devices enabling unidirectional light propagation by using non-reciprocal optical materials, namely materials able to break Lorentz reciprocity. The realization of isolators at terahertz frequencies is a very important ope ...

Microwave-gated dynamic nuclear polarization

David Lyndon Emsley, Geoffrey Bodenhausen, Aurélien Bornet, Sami Jannin, Arthur César Pinon, Xiao Ji, Mathieu Baudin

Dissolution dynamic nuclear polarization (D-DNP) has become a method of choice to enhance signals in nuclear magnetic resonance (NMR). Recently, we have proposed to combine cross-polarization (CP) with D-DNP to provide high polarization P(C-13) in short bu ...
