Experimental study of charging of dust grains in presence of energetic electrons
R. Paul, G. Sharma, K. Deka +4
The role of hot electrons in charging of dust grains is investigated in a two-temperature hydrogen plasma. A variety of dust particles are introduced into the system and secondary…
Sterile neutrino Dark Matter in the minimal Dirac Seesaw
J. Adhikary, A. Batra, K. Deka +1
We study sterile neutrino dark matter in a minimal Type-I Dirac seesaw framework where the states responsible for generating Dirac neutrino masses at tree level can be viable dark…
An Algorithm for the Constrained Longest Common Subsequence and Substring Problem
R. Li, J. Deka, K. Deka +1
Let be an alphabet. For two strings , , and a constrained string over the alphabet , the constrained longest common subsequence and substring problem for two str…
Effect of external magnetic field and dust grains on the properties of Ion Acoustic Waves
K. Deka, R. Paul, G. Sharma +7
An experimental study to investigate the effect of an external magnetic field on the propagation of ion-acoustic waves (IAWs) has been carried out in hydrogen plasma containing two…
An Algorithm for the Longest Common Subsequence and Substring Problem
R. Li, J. Deka, K. Deka
In this note, we first introduce a new problem called the longest common subsequence and substring problem. Let and be two strings over an alphabet . The longest common…
Study of two-electron temperature plasma sheath using nonextensive electron distribution in presence of an external magnetic field
G. Sharma, R. Paul, K. Deka +4
In this study, the physics of sheath formation in a collisional two-electron temperature plasma in the presence of an oblique external magnetic field has been investigated. At firs…
Bright-Moon Sky as a Wide-Field Linear Polarimetric Flat Source for Calibration
S. Maharana, S. Kiehlmann, D. Blinov +20
Next-generation wide-field optical polarimeters like the Wide-Area Linear Optical Polarimeters (WALOPs) have a field of view (FoV) of tens of arcminutes. For efficient and accurate…
Effect of collisions on the plasma sheath in the presence of an inhomogeneous magnetic field
K. Deka, S. Adhikari, R. Moulick +2
A low-pressure magnetized plasma is studied to find the dependency of sheath properties on ion-neutral collisions in presence of an inhomogeneous magnetic field. A self-consistent…
Experimental study on controlled production of two-electron temperature plasma
G. Sharma, K. Deka, R. Paul +4
A two-electron temperature plasma is produced by the method of diffusion of two different plasmas with distinct temperatures and densities. The method is simple and provides an ade…
