Unveiling the Quantum Toroidal Dipole
Alexandru-Lucian Nastasia, Mircea Dolineanu, Dragos-Victor Anghel
The electromagnetic response of matter is governed by three fundamental multipole families: electric, magnetic, and toroidal. While the electric and magnetic are cornerstones of ph…
The eigenvalues and eigenfunctions of the toroidal dipole operator in a mesoscopic system
Dragos-Victor Anghel, Mircea Dolineanu
We give analytical expressions for the eigenvalues and generalized eigenfunctions of , the -axis projection of the toroidal dipole operator, in a system consisting of…
The self-adjoint toroidal dipole operator in nanostructures
Mircea Dolineanu, Amanda Teodora Preda, Dragos-Victor Anghel
The parity violation in nuclear reactions led to the discovery of the new class of toroidal multipoles. Since then, it was observed that toroidal multipoles are present in the elec…
Observables compatible to the toroidal moment operator
Dragos-Victor Anghel, Amanda Teodora Preda
The quantum operator , corresponding to the projection of the toroidal moment on the axis, admits several self-adjoint extensions, when defined on the whole $\mathbb…
