Density modulations and superconductivity in two-dimensional quantum gases. The project aims to investigate the interplay between pairing (superfluidity) and pattern formation (eg stripes) in quasi-two-dimensional quantum systems. The close proximity of these phases is a recurring theme in layered materials which could hold the key to understanding phenomena such as high temperature superconductivity. The project plans to investigate these phases in dipolar gases, which provide a clean, controll ....Density modulations and superconductivity in two-dimensional quantum gases. The project aims to investigate the interplay between pairing (superfluidity) and pattern formation (eg stripes) in quasi-two-dimensional quantum systems. The close proximity of these phases is a recurring theme in layered materials which could hold the key to understanding phenomena such as high temperature superconductivity. The project plans to investigate these phases in dipolar gases, which provide a clean, controlled environment for novel many-body phenomena. Within this setting, it plans to test established theories of pairing and develop accurate descriptions of density modulations, thus providing fundamental insights into strongly correlated systems. The new states of matter discovered in the project could form the basis for new quantum devices; in particular, a deeper understanding of stripe phases may allow us to use them for data storage.Read moreRead less

This Fellowship aims to unravel the behaviour of new complex materials by investigating the nature of quasiparticles beyond the current paradigm. The key innovation is the use of trapped atoms, which allows new quantum theories and computational tools to be developed and precisely tested. The new knowledge generated by the Fellowship will advance a range of fields, including condensed matter physics, and could ultimately underpin a new generation of quantum devices featuring robust data memories, where information can be efficiently stored and extracted.Read moreRead less

Summary
Creation, detection, and decoherence of a "Schrödinger Cat". Ultra-cold physics is a new frontier of science, especially Bose-Einstein condensates, as mesoscopic quantum objects, are expected to have a revolutionary impact on future science and technology. This project aims to test the famous quantum mechanical prediction the "Schrödinger Cat" (neither dead nor alive) using ultra-cold physics.
