A model for the dynamics of COVID-19 infection transmission in human with latent delay
Amar N. Chatterjee, Teklebirhan Abraha, Fahad Al Basir +1
In this research, we have derived a mathematical model for within human dynamics of COVID-19 infection using delay differential equations. The new model considers a 'latent period'…
Effective spin dynamics of spin-orbit coupled matter-wave solitons in optical lattices
Kajal Krishna Dey, Golam Ali Sekh
We consider matter-wave solitons in spin-orbit coupled Bose-Einstein condensates embedded in optical lattice and study dynamics of soliton within the framework of Gross-Pitaevskii…
Electrical conductivity and shear viscosity of a pion gas in a thermo-magnetic medium
Pallavi Kalikotay, Snigdha Ghosh, Nilanjan Chaudhuri +2
We evaluate the electrical conductivity and shear viscosity of a interacting pion gas in a thermo-magnetic medium using the kinetic theory. The collision term of the relativistic B…
Dynamics of a Double-Impulsive Control Model of Integrated Pest Management Using Perturbation Methods and Floquet Theory
Fahad Al Basir, Jahangir Chowdhury, Delfim F. M. Torres
We formulate an integrated pest management model to control natural pests of the crop through the periodic application of biopesticide and chemical pesticides. In a theoretical ana…
Optical solitons in saturable cubic-quintic nonlinear media with nonlinear dispersion
Sudipta Das, Kajal Krishna Dey, Golam Ali Sekh
We study an intense-short pulse propagation in a saturable cubic-quintic nonlinear media in the presence of nonlinear dispersion within the framework of an extended variational app…
Insights from intracules and Coulomb holes
Golam Ali Sekh, Benoy Talukdar, Supriya Chatterjee
We point out that a typical two-electron distribution function in atoms and molecules often called the intracule depends sensitively on the electron-electron repulsion which leads…
