Sinusoidal excitations in reduced Maxwell-Duffing model
Utpal Roy, T. Soloman Raju, Prasanta K. Panigrahi
Sinusoidal wave solutions are obtained for reduced Maxwell-Duffing equations describing the wave propagation in a non-resonant atomic medium. These continuous wave excitations exis…
Complex solitons with power law behaviour in Bose-Einstein condensates near Feshbach resonance
Utpal Roy, Rajneesh Atre, C. Sudheesh +2
Complex, localized stable solitons, characterized by a power law behaviour, are found for a quasi-one-dimensional Bose-Einstein condensate near Feshbach resonance. Both dark and br…
Some intricacies of the momentum operator in quantum mechanics
Utpal Roy, Suranjana Ghosh, Kaushik Bhattacharya
In quantum mechanics textbooks the momentum operator is defined in the Cartesian coordinates and rarely the form of the momentum operator in spherical polar coordinates is discusse…
Reality of linear and angular momentum expectation values in bound states
Utpal Roy, Suranjana Ghosh, T. Shreecharan +1
In quantum mechanics textbooks the momentum operator is defined in the Cartesian coordinates and rarely the form of the momentum operator in spherical polar coordinates is discusse…
