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…
Quasi-superfluid and Quasi-Mott phases of strongly interacting bosons in shallow optical lattice
Subhrajyoti Roy, Rhombik Roy, Arnaldo Gammal +2
We explore the ground states of strongly interacting bosons in the vanishingly small and weak lattices using the multiconfiguration time-dependent Hartree method for bosons (MCTDHB…
Information theoretic measures on quantum droplets in ultracold atomic systems

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…
Role of spin-orbit coupling effects in rare-earth metallic tetra-borides : a first principle study
Ismail Sk, Nandan Pakhira
We have investigated the electronic structure of rare-earth tetraborides, , using first-principle electronic structure methods (DFT) implemented in Quantum Espress…
Controlling crop pest with a farming awareness based integrated approach and optimal control
Teklebirhan Abraha, Fahad Al Basir, Legesse Lemecha Obsu +1
We investigate a mathematical model in crop pest controlling, considering plant biomass, pest, and the effect of farming awareness. The pest population is divided into two compartm…
Qurzon: A Prototype for a Divide and Conquer Based Quantum Compiler
Turbasu Chatterjee, Arnav Das, Shah Ishmam Mohtashim +2
When working with algorithms on quantum devices, quantum memory becomes a crucial bottleneck due to low qubit count in NISQ-era devices. In this context, the concept of `divide and…
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…
Bicomplex Version of Lebesgue's Dominated Convergence Theorem and Hyperbolic Invariant Measure
