Dynamic fermion flavor mixing through transition dipole moments

open access: yesInternational Journal of Modern Physics A, 2023
In this paper, we show that Majorana neutrino flavor mixing can be driven by transition dipole moments in the presence of external electromagnetic fields. We demonstrate the sensitivity of the rotation mixing matrix to strong fields obtaining dynamical mass eigenstates in the two-flavor model. The three-flavor case, and extensions to the quark sector,

Constraining active-sterile neutrino transition magnetic moments at DUNE near and far detectors

open access: yesJournal of High Energy Physics, 2021
We consider the sensitivity of the DUNE experiment to a heavy neutral lepton, HNL (also known as sterile neutrino) in the mass range from a few MeV to a few GeV, interacting with the Standard Model via a transition magnetic moment to the active neutrinos,

Visualizations of electric and magnetic interactions in ECD and ROA [PDF]

open access: yesarXiv, 2019
The chiral source and its mechanism in the molecular system are of great significance in many fields. In this work, we proposed visualized methods to investigate physical mechanism of chiral molecule, where the electric and magnetic interactions are visualized with the transitional electric dipole moment, the transitional magnetic dipole moment and the

Gravitational wave and electroweak baryogenesis with two Higgs doublet models

open access: yesPhysics Letters B, 2022
We study stochastic gravitational wave production and baryon number generation at electroweak phase transition with the two Higgs doublet models. The produced stochastic gravitational wave during the strongly first-order phase transition can be probed by

Nonadiabatic Calculation of Dipole Moments [PDF]

open access: yesarXiv, 2009
We review some of the few available nonadiabatic calculations of dipole moments. We show that those carried out in a laboratory-fixed set of coordinate axes are bound to fail and discuss the more reasonable ones in a molecule-fixed reference frame. For completeness we also describe the standard Born--Oppenheimer calculations of dipole moments.

Breather-like pulses in a medium with the permanent dipole moment

open access: yes, 2005
The solutions of the reduced Maxwell-Bloch equations for an anisotropic two-level medium, which describe the propagation of electromagnetic pulses having a duration from a few field oscillations, are studied.

Polarized two-photon photoselection in EGFP: Theory and experiment [PDF]

open access: yes, 2018
In this work, we present a complete theoretical description of the excited state order created by two-photon photoselection from an isotropic ground state; this encompasses both the conventionally measured quadrupolar (K = 2) and the “hidden” degree of ...

Transition-Dipole Moments for Electronic Excitations in Strong Magnetic Fields Using Equation-of-Motion and Linear Response Coupled-Cluster Theory.

open access: yesJournal of Chemical Theory and Computation, 2019
An implementation of transition-dipole moments at the equation-of-motion coupled-cluster singles-doubles (EOM-CCSD) and CCSD linear response (LR) levels of theory for the treatment of atoms and molecules in strong magnetic fields is presented.

Determining Orientations of Optical Transition Dipole Moments Using Ultrafast X-ray Scattering.

open access: yesJournal of Physical Chemistry Letters, 2018
Identification of the initially prepared, optically active state remains a challenging problem in many studies of ultrafast photoinduced processes. We show that the initially excited electronic state can be determined using the anisotropic component of ...
