Advanced broadband CARS microscopy based on a supercontinuum-generating photonic crystal fiber

Member of: Trent University Graduate Thesis Collection
Name(s): Creator (cre): Porquez, Jeremy, Thesis advisor (ths): Slepkov, Aaron D, Degree committee member (dgc): Wortis, Rachel, Degree committee member (dgc): Gaspari, Franco, Degree committee member (dgc): Côté, Daniel, Degree granting institution (dgg): Trent University
Abstract: <p>I have developed and improved a coherent anti-Stokes Raman scattering (CARS) microscope based on the spectral focusing (SF) technique. The CARS microscope uses an 800 nm oscillator and a photonic crystal fibre module to generate the supercontinuum Stokes. The photonic crystal fibre was originally designed to generate light beyond 945 nm which is useful for CARS microscopy in the CH/OH… more

The Role of Dielectric Screening in SrTiO3-Based Interfaces

Name(s): Creator (cre): Raslan, Amany Khalil, Thesis advisor (ths): Atkinson, Bill, Degree committee member (dgc): Wortis, Rachel, Degree committee member (dgc): Gaspari, Franco, Degree granting institution (dgg): Trent University
Abstract: <p>We build a theoretical model for exploring the electronic properties of the two-dimensional (2D) electron gas that forms at the interface between insulating SrTiO3 (STO) and a number of perovskite materials including LaTiO3, LaAlO3, and GdTiO3. The model treats conduction electrons within a tight-binding approximation, and the dielectric polarization via a Landau-Devonshire free energy… more

Modelling the Lanthanum Aluminate-Strontium Titanate Interface with a Modified Transverse Ising Model

Name(s): Creator (cre): Chapman, Kelsey Sarah, Thesis advisor (ths): Atkinson, William A, Degree committee member (dgc): Wortis, Rachel, Degree committee member (dgc): de Haan, Hendrick, Degree granting institution (dgg): Trent University
Abstract: <p>In 2004 it was discovered that a two-dimensional electron gas (2DEG) forms at the interface between lanthanum aluminate (LAO) and strontium titanate (STO). This 2DEG exhibits a variety of electronic and magnetic phenomena, motivating intense research into its applicability to electronic devices. Over the years several models have been developed in theoretical exploration of this system.… more

A Cluster Approach Applied to the One-Dimensional Anderson-Hubbard Model

Name(s): Creator (cre): Allum, Donovan James McMurrich, Thesis advisor (ths): Wortis, Rachel, Degree committee member (dgc): Atkinson, Bill A, Degree committee member (dgc): de Hann, Hendrick, Degree granting institution (dgg): Trent University
Abstract: <p>S. Johri and R. Bhatt developed a real-space renormalization group approach aimed at extracting the localized single-particle eigenstates of the Anderson model from a large system by identifying clusters of resonant site potentials. E. Campbell generalized this real-space renormalization group approach using standard perturbation theory. Both approaches were intended to approximate the… more
