Cel This project will investigate the classical and quantum properties of electrons in semiconductor superlattices (SLs) and Bose-Einstein Condensates (BECs) in optical lattices. The applicant and host have discovered that these systems have many unique and technologically important features. In particular, they exhibit a highly unusual type of chaotic motion, non- KAM chaos, which has attracted wide theoretical interest, but not previously been realized in experiment. Non-KAM chaos provides an innovative mechanism for controlling the transmission of electrons and photons through semi-conductor and photonic devices: a critical area for the development of quantum electronic devices and ultra-fast switching. The project will explore this mechanism through two mutually-supporting tasks, linking together semiconductor technology, ultra-cold atomic physics, and non-linear dynamics Task A. Effects of non-KAM chaos on quantum transport in SLs and analogous photonic devices. Key objectives are to:(a) Explain recent observations, in Nottingham, of giant resistance fluctuations associated with the onset of non-KAM chaos;(b ) Develop SLs optimized for using non-KAM chaos to control device resistance and effect ultra-fast switching. Task B. Effects of non-KAM chaos on alkali-atom BECs. Key objectives are to:(a) Investigate how the onset of chaos affects the BEC ground state and excitation spectrum;(b ) Motivate experiments, which will provide insights into the SL and photonic systems considered in Task A. The project will provide training in the state-of-the-art theoretical, computational and experimental techniques required for interdisciplinary research at the interface between quantum electronics, atomic physics and non-linear science. The results will strengthen the hosts' internationally leading position in a research field that they pioneered. During the training, the applicant will collaborate with many world-class scientists, which will enable her to establish powerful international research networks when she returns to Poland. This will be of critical importance for the development of new research programmes and complementary teaching at the University of Wroclaw. Results of the project will lead to the development of innovative ultra-fast switches and sensors, thus providing wealth creation within the EU. The applicant will therefore gain considerable experience in Technology Transfer, which will enable her to develop projects from concept to commercial exploitation.
