Condensed matter physics is concerned
with understanding and exploiting the properties of solids and liquids
and the large area that this covers makes it the largest field of contemporary
physics. At the fundamental level, researchers in this field are interested
in uncovering the simple physical principles that underlay the often complex
behaviors of condensed matter systems. However, the importance of many
of these materials to present and future technologies also drives a large
amount of applied research in the field.
At UBC, condensed matter physics
spans this wide range of theoretical and experimental research on materials
of current interest, with considerable effort also devoted to applications
and the development of new materials and processes.
Topics of current interest
include the growth of semiconductor films using molecular beam epitaxy, the development of
optical materials and devices by engineering them at the nanometer scale, Crystal growth
and high temperature super-conductors, and utilizing unstable particles as probes for the
magnetic fields in novel materials.

TRIUMF
|
In order to successfully pursue
research in these areas, the department has extensive facilities available
for sample preparation, mainly in the Advanced Materials and Process Engineering
Laboratory
(AMPEL). Also on campus is
TRIUMF,
which houses one of the two best facilities
in the world for the use of
µSR, which uses decaying muons
to probe the inner workings of condensed matter systems. The
ISAC
facility at
TRIUMF
will soon bring other new experimental capabilities such as
ß-NMR, which proves to be
10 orders of magnitude more sensitive than conventional NMR.
There are also opportunities for access to major facilities elsewhere such
as the synchrotron at
Brookhaven . |

pitch lattice of through-holes.
|
The
Photonics and Nanostructures Laboratory
is involved in the
growth of optical devices on 5nm-500nm length scales. The hope is to be able to control the photonic and electronic eigenstates of the structures; by utilizing etching, electron beam lithography and deposition techniques to construct 3 dimensional semiconductor microstructures. The
successful development of this technology will serve as the foundation of the next and the next-to-next generation of photonics and electronics.
|
|
The
Molecular Beam Epitaxy Lab
is involved in semiconductor film growth, modelling and electronic and optical properties.
Specifically, the use of
Nitrides and Bismides and the fabrication of nanostructures utilizing deposition techniques.
This group pioneered the use of diffuse light scattering to dynamically monitor surface
morphology, and is currently researching the modeling of surface morphology and electronic structure of deposited films.

The
superconductivity group is one of the world leaders in high quality crystal growth, and the production
of high temperature superconductors. At their disposal are several world class laboratories
located within AMPEL, including a solid state chemistry lab, used to grow high quality crystals;
and a film growth lab, which is used to develop materials for the electronic applications of superconductors. Crystal growth research aside; this
groups research interests center on the growth and analysis of high temperature superconductors;
including industrial links to the Quantum-Computing firm D-Wave Systems..

Scanning Tunnel Microscopy (STM)
is a world famous technique renown for its capability of imaging the electron
clouds surrounding the atoms in real space, but it is capable of many more feats such
as: Move and position atoms and molecules individually; Perform spectroscopy including
spin polarization with sub-mV accuracy both in real and momentum space; Can film with
time resolution ranging from hours down to picoseconds; Probe a large variety of
conductive samples. The inherent versatility of STM has made it one of the most central
tools for modern condensed matter physics.

The
Quantum Materials Laboratory
is located in the AMPEL Building and is comprised
of the two research groups lead by
G.A. Sawatzky
and
A. Damascelli.
The research program involves the fabrication as well as the theoretical
and spectroscopic study of novel complex systems and nanostructured
materials. The goal is to develop new approaches and understanding in the
quantum theory of solids, and define new pathways for the fabrication of
materials and structures with innovative physical properties.

UBC physics also boasts a number of world class condensed matter theorists; whose research
interests include high temperature Superconductors, conformal field theory, photonic band-gap materials,
diluted magnetic superconductors, strong correlated electrons, and various applications of statistical mechanics.
