Doing spin physics with unpolarized particles
Igor P. Ivanov, Nikolai Korchagin, Alexandr Pimikov +1
Twisted, or vortex, particles refer to freely propagating non-plane-wave states with helicoidal wave fronts. In this state, the particle possesses a non-zero orbital angular moment…

Discriminating between and family transformations in the bilinear space of NHDM
Igor P. Ivanov, Celso C. Nishi
The scalar potential of the N-Higgs-doublet model (NHDM) is best analyzed not in the space of N complex doublets but in the -dimensional space of real-valued bilinears c…

Fate of the Landau-Yang theorem for twisted photons
Igor P. Ivanov, Valery G. Serbo, Pengming Zhang
Landau-Yang theorem is sometimes formulated as a selection rule forbidding two real (that is, non-virtual) photons with zero total momentum to be in the state of the total angular…
