Tensor Networks provide a representation of a quantum many-body wave-function (or a classical partition function) that is suitable for computational methods, mainly for low-dimensional problems (1D and 2D). The most mature branch of tensor networks is known as Matrix Product States (MPS), also...
Condensed Matter Physics
Condensed Matter Physics research at UQ spans experiment and theory; basic research and applications and works on systems ranging from biophysics to quantum matter.
Experimental condensed matter physics includes work in the Centre for Organic Photonics and Electronics (Namdas and Meredith groups) and Electronics and the Superconducting Quantum Devices Lab in the ARC Centre of Excellence for Engineered Quantum Systems (Federov group).
Theoretical work is carried out in the groups of Kassal, McCulloch, McKenzie and Powell. Topics studied include organic electronics, superconductivity, quantum magnetism, strongly correlated electrons, hydrogen bonding, chemical physics, and biophysics. We apply methods ranging from analytical theory to state-of-the-art computational methods, from electronic structure calculations to matrix product state methods. Much of our work is closely related to experiments, particularly in molecular materials.
