Review and application of the BenderWu Mathematica Package
(Brac University, 2018-12)
This thesis is the application of the BenderWu Mathematica package to
di erent physical systems. The code was developed to calculate wave function
and energy data of higher order perturbation theory in quantum mechanics.
The ...
Quantisation of Black hole horizon area and multipartite entanglement of Black hole information subsystems
(Brac University, 2019-12)
We formulate a model consisting of multipartite entanglement that helps provide a
physical significance to the Bekenstein-Hawking entropy obtained after quantising
the horizon area of a black hole as proposed by Jacob ...
An Introduction to Cosmic Inflation Theory
(BRAC University, 2021-01)
This thesis provides a detailed derivation of the Friedmann Equations in the frame work of general relativity and for an FLRW universe. An introduction to the theory
of cosmic inflation, the motivations for it, and, the ...
A two loop test of Matrix Big Bang Model
(Brac University, 2020-06)
In this thesis we expand the effective action for the Matrix Big Bang presented in [9, 10]
and indicate the interaction terms. Then we compute the two loop effective potential of this
Matrix Big Bang model. We show that ...
Supersymmetric gauge theory: an application of group theory in high energy physics and starobinsky model of cosmological ination
(BRAC University, 2016)
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 ...
Baryon acoustic oscillation and LSS formation in the nascent universe
(BRAC University, 2017)
The Cosmic Microwave Background Radiation (CMBR) and cosmological redshift are together regarded as the best available evidence for the Big Bang theory. Measurements of this radiation have made the inflationary Big Bang ...
Review of Einstein field equation solution rotational and non-rotational black holes
(BRAC University, 2017)
The origin of gravitational theory of relativity includes the discussion of Sir. Isaac Newton and Einstein’s theory of relativity. A brief derivation is introduced about the spherically symmetric solution of Einstein’s ...
The AdS-CFT correspondence and the black-hole information theory paradox
(BRAC University, 2017)
This thesis discusses the role of AdS/CFT correspondence in high-energy physics. It
concentrates on studying the mathematical black holes in various backgrounds, particularly in
the anti deSitter(AdS) space. In this ...
Quantum information theory and the black hole information paradox
(Brac University, 2020-10)
This thesis discusses the information-theoretic concepts of Black Holes. Its primary
focus is describing black hole dynamics with unitary operators within the
perspective of quantum information theory and AdS/CFT arguments ...
Out-of-time-order correlators as a measure of quantum chaos for sinai, cardioid and diamond billiards
(Brac University, 2023-05)
The field of quantum chaos studies how the chaotic dynamics of a classical system manifest in its quantum counterpart. Various indicators and measures of classical chaos have been discovered, such as the classical Lyapunov ...
