Yukawa scalar self energy at two loop and in the inflationary de Sitter spacetime
Sourav Bhattacharya, Moutushi Dutta Choudhury
We have considered the Yukawa theory at two loop in the inflationary de Sitter spacetime, for a massless minimally coupled scalar and a massless fermion. The one loop computation f…
Non-perturbative , and the dynamically generated scalar mass with Yukawa interaction in the inflationary de Sitter spacetime
Sourav Bhattacharya, Moutushi Dutta Choudhury
We consider a massless minimally coupled self interacting quantum scalar field coupled to fermion via the Yukawa interaction, in the inflationary de Sitter background. The fermion…
Squeeze flow of potato starch gel: effect of loading history on visco-elastic properties
Moutushi Dutta Choudhury, Shantanu Das, Sujata Tarafdar
In this work gelatinized potato starch is shown to retain the memory of past loading history. It exhibits a visco-elastic response which does not depend solely on instantaneous con…
Aggregation Patterns of Salt Crystalizing in Drying Colloidal Solvents
Moutushi Dutta Choudhury, Sayanee Jana, Sruti Dutta +1
We report a study of the structure of droplets of colloidal gels containing dissolved sodium chloride. The components segregate and form intricate patterns. The salt crystalizes in…
Pattern Formation in a Drying Drop of Starch Gel with Sodium Chloride
Moutushi Dutta Choudhury, Sayanee Jana, Sruti Dutta +1
A drop of aqueous potato starch gel with a certain mole fraction of NaCl, when dried on a glass slide, exhibits strong segregation and intricate pattern formation phenomena. The sa…
Spreading of Non-Newtonian and Newtonian Fluids on a Solid Substrate under Pressure
Moutushi Dutta Choudhury, Subrata Chandra, Soma Nag +2
Strongly non-Newtonian fluids namely, aqueous gels of starch, are shown to exhibit visco-elastic behavior, when subjected to a load. We study arrowroot and potato starch gels. When…
Oscillatory Spreading and Surface Instability of a Non-Newtonian Fluid under Compression
Moutushi Dutta Choudhury, Subrata Chandra, Soma Nag +2
Starch solutions, which are strongly non-Newtonian, show a surface instability, when subjected to a load. A droplet of the fluid is sandwiched between two glass plates and a weight…
