CP violation in neutral lepton transition dipole moment [PDF]

open access: yesJournal of High Energy Physics, 2020
The CP violation in the neutrino transition electromagnetic dipole moment is discussed in the context of the Standard Model with an arbitrary number of right-handed singlet neutrinos.

Interlevel absorption of electromagnetic waves by nanocrystal with divalent impurity [PDF]

open access: yesCondensed Matter Physics, 2014
The energy spectrum of central divalent impurity is calculated using the effective mass approximation in a spherical quantum dot (QD). The dipole moment and oscillator strength of interlevel transition is defined.

Hot spin spots in the laser-induced demagnetization [PDF]

open access: yesAIP Advances, 2012
Laser-induced femtosecond magnetism or femtomagnetism simultaneously relies on two distinctive contributions: (a) the optical dipole interaction (ODI) between a laser field and a magnetic system and (b) the spin expectation value change (SEC) between two

Ground and excited state characteristics of the nuclei with A = 6 [PDF]

open access: yesЯдерна фізика та енергетика, 2021
The binding energy, the root-mean-square radius, the magnetic dipole moment, the electric quadrupole moment, and the moment of inertia of the nucleus 6Li are calculated by applying different models.

Substituent Effects on the Solubility and Electronic Properties of the Cyanine Dye Cy5: Density Functional and Time-Dependent Density Functional Theory Calculations

open access: yesMolecules, 2021
The aggregation ability and exciton dynamics of dyes are largely affected by properties of the dye monomers. To facilitate aggregation and improve excitonic function, dyes can be engineered with substituents to exhibit optimal key properties, such as ...

[2.2]Paracyclophane-Based Chiral Platforms for Circularly Polarized Luminescence Fluorophores and Their Chiroptical Properties: Past and Future

open access: yesFrontiers in Chemistry, 2020
Quality of CPL fluorophore is defined by the vectors of electric dipole transition moment and imaginary magnetic dipole transition moment. The aim of this review is to introduce readers to a chiral moiety applicable to CPL studies focusing on chiral ...

Can Magnetic Dipole Transition Moment Be Engineered?

open access: yesAngewandte Chemie International Edition, 2023
AbstractThe development of chiral compounds with enhanced chiroptical properties is an important challenge to improve device applications. To that end, an optimization of the electric and magnetic dipole transition moments of the molecule is necessary.

Branching Ratios, Radiative Lifetimes, and Transition Dipole Moments for YbOH [PDF]

open access: yesThe Journal of Physical Chemistry A, 2020
Medium resolution ($ $ ~ 3 GHz) laser-induced fluorescence (LIF) excitation spectra of a rotationally cold sample of YbOH in the 17300-17950 cm$^{-1}$ range have been recorded using two-dimensional (excitation and dispersed fluorescence) spectroscopy.

Transition radiation of the neutrino toroid dipole moment [PDF]

open access: yesPhysics Letters B, 1998
We discuss the transition radiation of a neutrino induced by its toroid dipole moment ($ $) when crossing the interface between two different media with different refraction indices. A neutrino of 1 MeV energy emits approximately $10^{-40}$ keV at $ =e\sqrt{2}G_F/ ^2$.
