We seek to understand how the world works at the small scale. Quantum mechanics is the fascinating field that studies how nature works on the nano- and microscales. Several questions are still under investigation: What is the nature of the transition between the quantum mechanical laws and those of ordinary classical mechanics that large systems obey? How can one use the stronger coherences that arise in quantum systems to make possible more precise measurements or quicker computations?

We are a young theoretical quantum physics group working on addressing these questions from the lovely island of Malta. We are based in the Department of Physics at the University of Malta, a vibrant research-led department with active interests in the quantum world, applications of electromagnetism, instrumentation, and astrophysics. The work of our group spans the fields of quantum optics, including quantum optomechanics and quantum information, and quantum thermodynamics.

We are looking for an excellent and independent postdoctoral researcher to join us for two years to explore topological effects in optomechanical arrays. If you have experience in theoretical topological photonics or phononics, please contact André Xuereb for more information.

Science in the Mediterranean!

Together with the groups of Rupert Ursin and Anton Zeilinger (IQOQI Vienna), Davide Calonico (INRIM), and Italy's CNR, we have some awesome results at arXiv:1803.00583 and arXiv:1801.02698!

Research highlights

Snowflake Topological Insulator

We show how the snowflake phononic crystal structure, which recently has been realized experimentally, can be turned into a topological insulator for mechanical waves. This idea, based purely on simple geometrical modifications, could be readily implemented on the nanoscale.

Manipulating heat flow in quantum devices

We demonstrate theoretically that the observation of unidirectional flow of heat is possible within quantum cascaded systems.

Measurement-induced chaos

Repeated measurements of a cavity field and of one atom realsies a measurement-induced nonlinear quantum transformation of the relevant atomic states. This nonlinear quantum transformation exhibits measurement-induced chaos.
