MicrobioRaman: an open-access web repository for microbiological Raman spectroscopy data

Biomedical SERS – the current state and future trends

Surface enhanced Raman spectroscopy (SERS) is meeting the requirements in biomedical science being a highly sensitive and specific analytical tool. By employing portable Raman systems in combination with...

Ultrabroadband two-beam coherent anti-Stokes Raman scattering and spontaneous Raman spectroscopy of organic fluids: a comparative study

Spontaneous Raman spectroscopy is a well-established diagnostic tool, allowing for the identification of all Raman active species with a single measurement. Yet, it may suffer from low-signal intensity...

Observation of nonlinear response and Onsager regression in a photon Bose-Einstein condensate

The quantum regression theorem states that the correlations of a system at two different times are governed by the same equations of motion as the single-time averages. This provides a powerful framework...

Multivariate processing of airborne natural source electromagnetic data—application to field data from Gobabis (Namibia)

As deep-seated ore deposits become increasingly relevant for mineral exploration, the demand for time-efficient and powerful deep-sounding exploration methods rises. A suitable method for efficiently sensing...

Superconducting Qubit Network as a Single Microwave Photon Detector for Galactic Axion Search

Experimental search of galactic axions requires detection of single photons in the microwave range. We work on a novel approach to detect single microwave photons based on a coherent collective response...

Quantum and phase diffusion crossovers in small Al Josephson junctions

Switching current distributions (SCDs), describing switching statistics from a superconducting to a resistive state, are measured for a set of aluminum-made Josephson junctions (JJ) in a temperature range...

Controllable coupling between fundamental modes in an asymmetric superconducting coplanar waveguide resonator

Controllable coupling between the odd and even fundamental modes of an asymmetric half-wavelength superconducting coplanar waveguide resonator is demonstrated. The resonant frequency of the even mode Xe...

Exploring the Reconfigurable Memory Effect in ElectroformingFree YMnO3-Based Resistive Switches: Towards a Tunable Frequency Response

Memristors, since their inception, have demonstrated remarkable characteristics, notably the exceptional reconfigurability of their memory. This study delves into electroforming-free YMnO3 (YMO)-based...

Beyond the first coordination sphere – manipulating the excited state landscape in iron(II) chromophores with protons

Molecular transition metal chromophores play a central role in light harvesting and energy conversion. Recently, earth-abundant transition-metal-based chromophores have begun to challenge the dominance...
