The emergence of collective, oftentimes macroscopically observable behaviour from interacting quantum systems yields surprising phenomena and new insights.
Striking examples include superconductivity (the collective flow of electrons with zero resistance), and the fractional quantum Hall effect (where many electrons act in concert to counter intuitively create new particles with a charge smaller than that of any individual electron).
The discovery and understanding of novel forms of collective quantum behaviour are at the frontier of fundamental condensed matter exploration. These phenomena have the further potential to make their way into technological applications – for example, the achievement of room-temperature superconductivity would have an extraordinary impact upon society at large.
Experimental studies of cold atomic gases are targeted at the study of novel phase behaviour in correlated atomic systems, from the quantum behaviour of systems far from equilibrium to quench dynamics and turbulence in atomic condensates.
In the area of correlated electronic matter, materials synthesis, tuning, and high precision measurements are used to uncover novel quantum collective phenomena such as unconventional superconductivity, quantum phase transitions, new forms of magnetism, and quantum multi-functionality.
Studies of low-dimensional and hybrid quantum systems include manifestations of quantum coherence effects, from quantum transport phenomena to topological insulating behaviour. Hybrid light-matter systems are used to study optical control of quantum-dot spins, diamond-based emitters, solid-state cavity quantum electrodynamics, and nanoplasmonics.
Understanding these systems poses some of the tallest theoretical challenges, involving diverse aspects of quantum many-body systems, from coherence phenomena in atomic, electron and light-matter systems, to frustrated magnetism and topological phases of matter.
