Magnetic Dipole Moment of Neutrino [PDF]
JHEPGC , Vol.01 No.01(2015), Article ID:56270,12, 2015 We recalculate the magnetic moment of neutrinos in a hot and dense medium. The magnetic dipole moment of neutrinos is modified at high temperature and chemical potential. We show that the magnetic dipole moment of electron neutrino does not get a significant contribution from thermal background to meet the cosmological bound.

Nondestructive Measurement of Orbital Angular Momentum for an Electron Beam [PDF]
, 2016 Free electrons with a helical phase front, referred to as "twisted" electrons, possess an orbital angular momentum (OAM) and, hence, a quantized magnetic dipole moment along their propagation direction. This intrinsic magnetic moment can be used to probe

Measuring the orbital angular momentum spectrum of an electron beam [PDF]
, 2017 Electron waves that carry orbital angular momentum (OAM) are characterized by a quantized and unbounded magnetic dipole moment parallel to their propagation direction.

Physics Letters B, 2023 We present a new design of highly specialized small storage rings for low energy polarized electron beams. The new design is based on the transparent spin methodology that cancels the spin precession due to the magnetic dipole moment at any energy while ...

2D Spin-Dependent Diffraction of Electrons From Periodical Chains of Nanomagnets
Applied Sciences, 2012 The scattering of the unpolarized beams of electrons by nanomagnets in the vicinity of some scattering angles leads to complete spin polarized electrons. This result is obtained with the help of the perturbation theory.

Thermo-magneto coupling in a dipole plasma [PDF]
Phys. Plasmas 19 (2012), 072303 1--5, 2012 On a dipole plasma, we observe the generation of magnetic moment, as the movement of the levitating magnet-plasma compound, in response to electron-cyclotron heating and the increase of $\beta$ (magnetically-confined thermal energy). We formulate a thermodynamic model with interpreting heating as injection of microscopic magnetic moment; the ...

Transverse spin asymmetries at the EIC as a probe of anomalous electric and magnetic dipole moments [PDF]
, 2023 We show that inclusive single-spin asymmetries (SSAs) with transversely polarized protons or electrons at a future electron ion collider (EIC) are sensitive to new physics contributions to electroweak dipole operators of electrons and quarks.

Electric Dipolar Kondo Effect Emerging from Vibrating Magnetic Ion [PDF]
Phys. Rev. Lett. 108, 247214 (2012), 2012 When a magnetic ion vibrates in a metal, it inevitably introduces a new channel of hybridization with conduction electrons and in general, the vibrating ion induces electric dipole moment. In such a situation, we find that magnetic and non-magnetic Kondo effects alternatively occur due to the screening of spin moment and electric dipole moment of ...

Magnetic and Electric Dipole Constraints on Extra Dimensions and Magnetic Fluxes [PDF]
Nucl.Phys.B811:353-362,2009, 2008 The propagation of charged particles and gauge fields in a compact extra dimension contributes to $g-2$ of the charged particles. In addition, a magnetic flux threading this extra dimension generates an electric dipole moment for these particles. We present constraints on the compactification size and on the possible magnetic flux imposed by the ...
