On an atom with a magnetic quadrupole moment in a rotating frame

Abstract

The quantum description of an atom with a magnetic quadrupole moment in the presence of a uniform effective magnetic field is analysed. The atom is also subject to rotation and a scalar potential proportional to the inverse of the radial distance. It is shown that the spectrum of energy is modified, in contrast to the Landau-type levels, and there is a restriction on the possible values of the cyclotron frequency which stems from the influence of the rotation and scalar potential proportional to the inverse of the radial distance.

Landau quantization for an electric quadrupole moment of position-dependent mass quantum particles interacting with electromagnetic fields

“…For example, the Aharonov-Bohm effect [1][2][3][4] for a charged particle, the scalar Aharonov-Bohm and He-Mckellar-Willens effects [5][6][7][8][9][10][11], for bound states [12], and Landau quantization [13][14][15][16] for an electric dipole moment of a neutral particle. Furthermore, recent studies have investigated the interaction between the quadrupole moments of neutral particle and external fields in several quantum systems such as geometric quantum phases [17], noncommutative quantum mechanics [19], nuclear structure [20,21], atomic systems [22][23][24][25][26][27], molecular systems [28][29][30], and Landau quantization [18,[31][32][33].…”
