On non-Hermitian quantum mechanics.
The purpose of this dissertation is to review the salient features of non-Hermitian quantum mechanics. An introduction to Hermitian quantum mechanics is included to make this review as accessible as possible. Attempts ...
Magnetic properties of Mg₁-xZnxFe₂O₄ nanoferrites and tetracycline-ferrite nanocomposites.
Abstract available in print copy.
Study on 2002 sudden stratospheric warming, mesopher-lower thermospheric wind structure and dynamics and middle atmospheric structure, based on superDARN HF RADAR, LIDAR, Riometer, satellites and models.
In this thesis, the dynamics and coupling in the middle atmosphere over the Southern Hemisphere are investigated using SuperDARN high frequency (HF) radar wind data, satellites, light detection and ranging (LIDAR), the ...
Digital, statistical and wavelet study of turbulence flow structure in laboratory plunging water waves.
This dissertation presents an experimental investigation set out to study the evolution of turbulence in laboratory generated breaking water waves. The waves propagate and break as plunging waves on a 1:20 sloping beach. ...
The implementation of polarisation encoded quantum key distribution in fibre.
Quantum Key Distribution (QKD) employs the laws of quantum mechanics for the purpose of cryptography. Two parties, commonly called Alice and Bob, are able to share a random key which is used to encrypt a message. Any ...
Title: Study of anomalous VLF perturbations in possible relation to seismic activity.
Anomalous perturbations of the ionosphere have been observed either as uctuations in the critical frequency of the F-region ionosphere, foF2, or as uctuations in the nighttime VLF signals that propagate through the ...
Invariant multipole theory of induced macroscopic fields in homogenous dielectrics.
A harmonic plane electromagnetic wave incident on a molecule distorts its charge distribution, thereby producing an infinite series of induced multipole moments expressed in terms of contributions that are due to the ...
Optimizing quantum communication through hybrid technology.
Quantum Key Distribution (QKD) is a symmetric key sharing protocol. The theoretical process exploits the principles of quantum physics to underpin a physical security against any form of eavesdropping. QKD not only ensures ...
Generation and detection of bessel beams.
In this dissertation we study the properties of Bessel-Gauss beams. Bessel-Gauss beams are created by the interference of plane waves lying on a cone, and have unique properties: they propagate without spreading and ...
Exactly solvable models for qubits coupled to spin environments : decoherence and entanglement.
During the last decade the field of quantum information has seen considerable progress both theoretically and experimentally. The building block of this theory is the so-called qubit, the quantum counterpart of the ...
