Project name: Quantum engineering in cold atomic gasses (Nr. 09.3.3-LMT-K-712-01-0051)

Project No. (Nr. 09.3.3-LMT-K-712-01-0051)

This project has received funding from the European Social Fund under the No. 09.3.3-LMT-K-712 “Development of Competences of Scientists, other Researchers and Students through Practical Research Activities” measure under grant agreement with the Research Council of Lithuania (LMTLT).

Duration: 4 years (2018-01-08 - 2022-01-07)

Project leader: Prof. E. Anisimovas

Cold atomic gases offer broad opportunities for quantum engineering. These systems are perfectly isolated from the environment, remarkably clean and offer an unprecedented degree of control through light-matter interaction. Successful experiments and demonstrations rapidly proceed towards ever increasing levels of quantum complexity. However, in spite of rapid advances, recent experiments have also met with rather hard limitations such as heating – the unwanted generation of entropy due to the external perturbation by the driving signal. The proposal aimed to elucidate the role of interactions, internal degrees of freedom and structured gauge fields in out-of-equilibrium dynamics of cold-atom systems and to propose a new generation of periodic driving schemes.

Project name: Homogenous optical traps for ultracold atoms

Project No. 09.3.3.-LMT-K-712-25-0110

This project has received funding from the European Social Fund under the No. 09.3.3-LMT-K-712 “Development of Competences of Scientists, other Researchers and Students through Practical Research Activities” measure under grant agreement with the Research Council of Lithuania (LMTLT).

Duration: from 2021-09-01 to 2022-03-31

Supervisor: prof. Gediminas Juzeliūnas

Student: Edvinas Gvozdiovas

Summary: The student will investigate ultracold atoms in flat cylindrical potential traps by using light beams with orbital angular momentum. He will analyze the full Hamiltonian of the system characterized by the Lambda atom-light coupling scheme, and will investigate the effective model in the dark state manifold.

Aim of the project: the student will have analyzed the energy spectrum and atomic dynamics, and will present recommendations on how to minimize non-adiabatic losses.

Project name: Effective magnetic field and periodic potential barriers for ultracold atoms

Project No. 09.3.3-LMT-K-712-24-0114

This project has received funding from the European Social Fund under the No. 09.3.3-LMT-K-712 “Development of Competences of Scientists, other Researchers and Students through Practical Research Activities” measure under grant agreement with the Research Council of Lithuania (LMTLT).

Duration: from 2021-07-05 to 2021-08-31

Supervisor: prof. Gediminas Juzeliūnas

Student: Edvinas Gvozdiovas

Summary: Over the course of this project, the student will investigate a new way to form artificial magnetic fields and periodic lattice potentials for ultracold atoms via atom-light interactions, creating excitations between atomic internal states. Research on ultracold atoms is important not just fundamentally, but also useful for practical applications, such as precise measurements, quantum computation, and quantum simulators.

Aim of the project: the student will improve their knowledge in ultracold atomic physics. He will analyze the atomic dynamics in the optical Lambda setup, where the atom is affected by traveling optical waves in three directions. He will numerically evaluate the band structure, and will compare the results with the effective model for the system.

Project: Non-classical spin states in ultracold atomic gases

Project No. 09.3.3-LMT-K-712-23-0035

Project is funded by the European Social Fund, project code No. 09.3.3-LMT-K-712-19-0013, the Grant is administered by the Lithuanian Research Council

Duration: 2021-07-01 – 2023-07-01

Postdoctoral fellow: dr. Mažena Mackoit-Sinkevičienė

Supervisor: prof. dr. Gediminas Juzeliūnas

Summary: The main goal of the project is to analyze the non-classical states of spinful ultracold atoms affected by the periodic driving and spin-orbit coupling with the spin degree of freedom included. The periodic driving can be used as an alternative mechanism to facilitate creation of non-classical spin states and the spin squeezing via such a non-local interaction for ultracold atomic fermions in optical lattices. The interaction induced by the periodic driving can be turned on and off at appropriate times. Such a flexibility is important for the spin squeezing applications in order to reach the optimum squeezing. The studies to be carried out are expected to be used as direct recommendations for cold atom experiments.
