Effective ﬁeld theories have proven to be efﬁcient tools for studying physics at length scales longer than that which is typical. Chiral Perturbation Theory is one of these EFTs which physicists rely on heavily to study ...
This thesis discusses the general role of symmetry in high-energy physics. It concentrates
on the role of fermionic symmetry generators, which generate the symmetry known as
supersymmetry. An extensive discussion of ...
Electrical conduction is the
ow of electron due to a force applied by an
electric eld. In bulk material, conduction process obeys Ohm's law. The
law states that current is proportional to applied voltage. But nano-sized ...
This thesis reviews the exact numerical computation of the classical bounce solution in
the false vacuum decay for a quartic scalar eld potential which is o set by an external
source. The decay rate in a semiclassical ...
