JETP Letters, 2009 The roton excitation in the superfluid He-4 does not possess a stationary dipole moment. However, a roton has an instantaneous dipole moment, such that at any given moment one can find it in the state either with positive or with negative dipole moment ...

The Muon Electric Dipole Moment [PDF]
B Physics and CP Violation, 1997 The electric dipole moment of the muon ($d_\mu$) is evaluated in a two Higgs doublet model with a softly broken discrete symmetry. For $\tan\beta \equiv |v_2|/|v_1| \sim 1$, contributions from two loop diagrams involving the $t$ quark and the $W$ boson ...

Quark Chromoelectric Dipole Moment Contribution to the Neutron Electric Dipole Moment [PDF]
Proceedings of 34th annual International Symposium on Lattice Field Theory — PoS(LATTICE2016), 2016 The quark chromo-electric dipole moment operator and the pseudo-scalar fermion bilinear with which it mixes under renormalization can both be included in a calculation of the electromagnetic form factor of the nucleon using the Schwinger source method.

Magnetic dipole moment of a moving electric dipole [PDF]
American Journal of Physics, 2012 The current density of a moving electric dipole is expressed as the sum of polarization and magnetization currents. The magnetic field due to the latter current is that of a magnetic dipole moment that is consistent with the relativistic transformations ...

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

Measurement of the Permanent Electric Dipole Moment of the Neutron. [PDF]
Physical Review Letters, 2020 We present the result of an experiment to measure the electric dipole moment (EDM) of the neutron at the Paul Scherrer Institute using Ramsey's method of separated oscillating magnetic fields with ultracold neutrons.

Anomalous Diffusion in Dipole- and Higher-Moment-Conserving Systems. [PDF]
Physical Review Letters, 2020 The presence of global conserved quantities in interacting systems generically leads to diffusive transport at late times. Here, we show that systems conserving the dipole moment of an associated global charge, or even higher-moment generalizations ...

AIP Conference Proceedings, 2004 From the famous experiments of Stern and Gerlach to the present, measurements of magnetic dipole moments, and searches for electric dipole moments of ``elementary'' particles have played a major role in our understanding of sub-atomic physics. In this talk I discuss the progress on measurements and theory of the magnetic dipole moments of the electron ...
