The department of physics offers a thesis-based M.Sc. program which currently focuses on condensed matter physics, materials science and biophysics. The M.Sc. thesis can involve a theoretical or experimental project. Potential fields of research which may be pursued are described below.

Successful completion of an Honours Bachelor's degree, or equivalent, in Physics with a minimum B overall average. Applicants holding a degree without sufficient concentration in the area of the intended Master's degree, may be required to complete additional courses beyond those outlined as required for degree completion. The Graduate Record Examination (GRE) is recommended for international students but not required. Agreement from a faculty advisor to supervise the student is also required for admission to the program.

The Graduate Admissions Committee will review all applications and recommend admission for a limited number of suitable candidates.

Part-time candidates may be considered.

The program must include PHYS 5F90 and two credits, of which at least one and one-half credits must be graduate courses. Further credits may be required where a candidate is deficient in a particular area of study.

For full-time students, the program is a six term or two year program.

The department's main research emphasis is on condensed matter physics. The following research fields are currently being pursued:

Lattice dynamics: lattice vibrations in simple metals, thermodynamics of anharmonic crystals, formalism of interacting many-body systems, Monte Carlo and molecular dynamics simulations.Superconductivity: unconventional pairing, novel materials (high-Tc, magnetic, etc.), localization and superconductivity, superconducting glassy state.Transport in metals: transport properties of heavy fermion systems.Non-crystalline materials: calculation of electronic structure and transport properties of amorphous and liquid metals, quasicrystals, alloys and semiconductors, vibrational and magnetic properties of amorphous solids. Linear response calculations of electron-phonon interaction and superconductivity in solids.Unconventional superconductivity: magnetic superconductors, high temperature superconductors, strongly correlated electron systems in one and two dimensions. Mesoscopic physics. Quantum Monte Carlo studies of physical properties of isolated atoms and molecules. Monte Carlo and molecular dynamics studies of biological molecules.

Investigation of the optical properties of materials with phase transitions (e.g., ferromagnets, superconductors, heavy fermion, spin- and charge-density wave compounds) via optical spectroscopy from mm wave to uv.Preparation and characterization of ceramic, single crystal and thin film (using pulsed-laser deposition) high Tc superconductors, CMR materials (manganites) and amorphous alloys. Magnetic and transport properties at ambient and high pressure utilizing measurement techniques such as SQUID magnetometry, specific heat and dc-resistivity.

Nuclear Magnetic Resonance spectroscopy and relaxation measurements in soft condensed matter systems. Study of collective motions in model membranes, phase transitions in liquid crystals.

Exploration of various morphologies and phase behavior of lipid/water systems using scattering techniques (e.g. Neutrons, x-ray and light). Study of the protein/membrane interactions; structural characteristics of membrane active peptides.

Biophysics of photosynthetic energy conversion using a combination of specialized optical spectroscopic techniques and theoretical models for excitation energy transfer and electron transport. Time resolved Electron Spin Resonance spectroscopy and light-induced spin polarization in photosynthetic membrane proteins and donor acceptor molecular complexes. Investigation of energy and electron transfer and spin dynamics in these systems. Experimental research facilities are supported by electronics, glassblowing and machine shop services. The University provides extensive computing facilities using Silicon Graphics UNIX servers and high performance Beowulf clusters.

A number of fourth-year courses carrying graduate credit are offered by the department and can be selected with the permission of the Supervisor and the Graduate Program Director.

Note: Not all courses are offered in every session. Students must consult with the Graduate Program Director regarding course offerings and course selection and must have their course selections approved by the Graduate Program Director each term. Refer to the Timetable for scheduling information:
