Project: Ultracold atoms in unconventional optical lattices
Duration: 2024-09-01 - 2027-08-31
Principal investigator: habil. dr. Gediminas Juzeliūnas (FP, ITPA)
Summary:
The objective of the project is to study unconventional optical lattices for ultracold atoms involving optical transitions between the atomic internal (spin) states and interaction between the atoms. For this purpose we have formulated and will solve problems which can be conditionally divided into the following two mutually related groups: Group of problems 1. Ultracold atoms in subwavelength optical lattices:
1.1 Effects of atom-atom interaction in subwavelength optical lattices.
1.2. Subwavelength lattices in higher dimensions. Group of problems 2. Ultracold atoms in spinor optical lattices:
2.1 Atom-atom interaction in spinor subwavelength lattices
2.2. Optical lattices for atoms characterised by a larger spin. The problem group 1 will concentrate on the subwavelength optical lattices and effects of atomatom interaction in them. The Problem group 2 will explore effects of spin degrees of freedom for the many body effects in unconventional optical lattices. In particular, it is planned to explore possibilities of an enhanced spin squeezing mechanism for atoms characterised by a large spin. This should enable to increase the accuracy of atomic clocks.
