Dynamical symmetry breaking of lambda and vee-type three-level systems on quantization of the field modes
Mihir Ranjan Nath, Surajit Sen, Asoke Kumar Sen +1
We develop a scheme to construct the Hamiltonians of the lambda, vee and cascade type of three-level configurations using the generators of SU(3) group. It turns out that this appr…
On the microscopic basis of Newton's law of cooling and beyond
Mihir Ranjan Nath, Surajit Sen, Gautam Gangopadhyay
The microscopic basis of Newton's law of cooling and its modification when the difference in temperature between the system and the surroundings is very large is discussed. When th…
Effect of field quantization on Rabi oscillation of equidistant cascade four-level system
Mihir Ranjan Nath, Tushar Kanti Dey, Surajit Sen +1
We have exactly solved a model of equidistant cascade four-level system interacting with a single-mode radiation field both semiclassically and quantum mechanically by exploiting i…
Dynamics of cascade three-level system interacting with the classical and quantized field
Mihir Ranjan Nath, Surajit Sen, Gautam Gangopadhyay
We study the exact solutions of the cascade three-level atom interacting with a single mode classical and quantized field with different initial conditions of the atom. For the sem…
