Charged Scalar Field in an external magnetic Field: Renormalisation and Universal Diamagnetism
Debnarayan Jana
The physical and mathematical mechanism behind diamagnetism of N (finite) spinless bosons (relativistic or non-relativistic) is well known. The mathematical signature of this diama…
Imbibition: An Example of Nonconserved Cellular Automaton
P. B. Sunil Kumar, Debnarayan Jana
We report an imbibition experiment in 2D random porous media in which height - height correlation function grows with a nonuniversal exponent. We find the exponent to depend on eva…
Nonuniversality in Imbibition
P. B. Sunil Kumar, Debnarayan Jana
We report an imbibition experiment in 2D random porous media in which height - height correlation function grows with a nonuniversal exponent; rather it depends on evaporation. We…
Universal Diamagnetism of Charged Scalar Fields
Debnarayan Jana
We show that charged scalar fields are always diamagnetic, even in the presence of interactions and at finite temperatures. This generalises earlier work on the diamagnetism of cha…
