Dual-comb optical activity spectroscopy for the analysis of vibrational optical activity induced by external magnetic field

open access: yesNature Communications, 2023
Dual-comb spectroscopy was first applied to the measurement of magnetic optical activity spectroscopy, realizing Doppler-limited gas-phase molecular analysis, and was further extended to the rapid measurement of liquid-phase chiroptical activity.

Advantages and developments of Raman spectroscopy for electroceramics [PDF]

open access: yesCommun Mater 4, 78 (2023), 2023
Despite being applied with success in many fields of materials science, Raman spectroscopy is not yet determinant in the study of electroceramics. Recent experimental and theoretical developments, however, should increase the popularity of Raman spectroscopy in this class of materials.

Intramolecular vibrational dynamics of ν1 mode in (CF3)2C=C=O molecule induced by resonant IR femtosecond radiation

open access: yesEPJ Web of Conferences, 2017
Intramolecular dynamics of the vibrational levels (up to v = 5) of the ν1 mode in (CF3)2CCO molecule, induced via multiphoton selective excitation of this mode by resonant femtosecond IR radiation, was studied.

Tracing multiple scattering trajectories for deep optical imaging in scattering media

open access: yesNature Communications, 2023
Multiple light scattering hampers imaging objects in complex scattering media. Approaches used in real practices mainly aim to filter out multiple scattering obscuring the ballistic waves that travel straight through the scattering medium.

Dual-frequency Doppler-free spectroscopy for simultaneous laser stabilisation in compact atomic physics experiments [PDF]

open access: yes, 2021
Vapour cell spectroscopy is an essential technique in many fields; in particular, nearly all atom and ion trapping experiments rely on simultaneous spectroscopy of two atomic transitions, traditionally employing separate apparatus for each transition.

Oscillon spectroscopy

open access: yesJournal of High Energy Physics, 2023
Abstract The sine-Gordon model in 3+1 dimensions is known to admit two oscillons of different energy and frequency but comparable lifetime. We show that the oscillon spectrum includes more spherically symmetric “states”. We identify new high-amplitude oscillons by allowing the field profile to have a number of nodes.

Exploring optoelectronic properties and mechanisms of layered ferroelectric K4Nb6O17 nanocrystalline films and nanolaminas

open access: yesScientific Reports, 2017
Two-dimensional layered K4Nb6O17 (KN) was easily formed as a secondary phase caused by the volatilization of alkali metal ions, when preparing ferroelectric K x Na1−x NbO3 based ceramics and films.

H-magnetic resonance spectroscopy. diagnostic tool in recurrent headache in systemic lupus erythematosus. a case report [PDF]

open access: yes, 2018
We describe serial MR-spectroscopy studies in a patient with systemic lupus erythematosus and headache. We used MR-spectroscopy to monitor disease activity during periods with and without headache.

Frequency stabilization of diode laser on the wavelength of 5P3/2→5D5/2 of rubidium transition

open access: yesEPJ Web of Conferences, 2017
The method of frequency stabilization of diode laser on the wavelength of 5P3/2→5D5/2 of rubidium (776 nm) has been realized. The two-photon absorption spectroscopy of the rubidium vapors is underlie of the suggested scheme.
