Available Projects

Title Body Level
SRS-21/17 Quantum card games

Suitable for:  Students with an interest in quantum physics.

Project:  Classical information is represented as bits in a string of 0s and 1s.  In quantum mechanics, anything in between is possible - you can have superpositions of 0s and 1s...

Summer Project
SRS-17/17 Demonstrating the Jarzynski equality in a superfluid

Suitable for:  Students with an interest in computational science and theoretical quantum physics.  Students should have completed at least two years of physics study, and be familiar with quantum mechanics, thermodynamics, and preferably statistical mechanics.

Summer Project
SRS-12/17 Physics models of higher-order interactions in plant communities

Suitable for:  Students interested in theoretical and computational quantum physics.

Project:  This project aims to use the methods of statistical physics to help understand the equilibrium and dynamics and of interacting plant communities (with...

Summer Project
SRS-11/17 Pairing phase of the attractive Bose gas

Suitable for:  Students interested in theoretical and computational quantum physics.

Project:  In the 1970s there was speculation that the cause of superfluidity in helium-4 was not due to Bose-Einstein condensation, but a form of Cooper pairing...

Summer Project
SRS-10/17 Superfluidity under a quench of interaction strength in a persistent current

Suitable for:  Students interested in theoretical and computational quantum physics.

Project:  One of the key insights of Landau was to derive a phenomenological formula for the critical velocity in a superfluid.  In a Bose gas this is...

Summer Project
SRS-09/17 Nonequilibrium superfluid flows

Suitable for:  Students interested in theoretical and computational quantum physics. 

Project:  The aim of this project is to make a connection between classical mechanics and quantum mechanics - looking for the signatures of classical...

Summer Project
Superfluidity in a trapped Bose-Einstein condensate with an oscillating barrier

Floquet theory finds solutions to Hamiltonian systems that are periodic in time.  They are easy to find via ...

Honours Project
Summer Project
Finite temperature Josephson junctions

When two superfluids are connected by a weak link, they exhibit the Josephson effect – oscillations in the current between the two fluids.  This project would...

Summer Project
Nonequilibrium superfluid flows

See Mason, D. J., Borunda, M. F., & Heller, E. J. (2015). Revealing the flux: Using processed Husimi maps to visualize dynamics of bound systems and...

Honours Project
Summer Project
Thermodynamics in the microcanonical ensemble

Some recent developments in statistical mechanics have come up with new geometric interpretations of thermodynamic quantities.  This project would look at applying these ideas to the Bose gas.  In particular, it would be to analytically incorporate additional conserved quantities into...

Nonequilibrium superfluidity in polariton condensates

Polariton condensates occur in two-dimensional semiconductor microcavities pumped by a laser.  The light excites electrons from the valence band to the conduction band,...

Pairing phase of the degenerate Bose gas

In the 1970s there was speculation that the cause of superfluidity in helium-4 was not due to Bose-Einstein condensation, but a form of Cooper pairing between attractive bosons,...

Summer Project
Thermalisation of a spin-1 Bose gas in a double well

This project simulates the quantum dynamics of a “spin-1” Bose gas in a double well potential.  A spin-1 gas has three spin components, which can interconvert due to spin-collisions (...

Summer Project
Nonequiilbrium flows and superfluid turbulence in dilute gas Bose-Einstein condensates

Dilute gas Bose-Einstein condensates (BECs) were experimentally observed for the first time in 1995, more than seventy years after their initial proposal by Einstein.  Like helium-4 below the lambda point, they exhibit the defining...

Monte-Carlo algorithm for sampling the thermodynamic properties of the 1D Bose gas at finite temperature

The stochastic Gross-Pitaevskii formalism can sample the grand-canonical ensemble for the interacting Bose gas by assuming the ergodic hypothesis that time evolution fairly...

Summer Project
Quantum thermalisation

How do isolated quantum systems thermalise?  Isolated quantum systems undergo unitary evolution which preserves the entropy.  However, at the level of statistical mechanics, any disturbance will lead to an increase in entropy...
