Electrostatic drift waves in a nonuniform quantum magnetized electron-positron (pair) plasma are investigated. An explicit and straightforward analytical expression of the fluctuation frequency is presented. The effects induced by quantum fluctuations, density gradients, and magnetic field inhomogeneity on the wave frequencies are discussed and a purely quantum drift mode appears. The present analytical investigations are relevant to dense astrophysical objects as well as laboratory ultracold plasmas.

    It is shown that zero-field potentials may be responsible for the Aharonov-Bohm effect. A magnetic field B = curlA[sup f] has a physical (gauge-invariant) meaning for field potentials A[sup f], whereas a circulation ...[sub C]A[sup 0] dr has a physical meaning for zero-field potentials A[sup 0].

    Quantum beats of the Na(3 2P3/2–3 2S1/2) transition and their change with the magnetic field were observed in pure Na vapor and Na+He gas by using a picosecond laser system. The energies of the hyperfine and Zeeman sublevels of the 3 2P3/2 and 3 2S1/2 states were calculated by using the...

    The rotational transform associated with the magnetic surfaces of a toroidal magnetic field with a nonplanar axis is an example of the angle anholonomy which recently has been much discussed in quantum and classical dynamics (the Berry phase and Hannay angle). The same anholonomic angle appears...
