✅Ultrafast phenomena and vacuum effects in relativistic artificial atoms created in graphene PI: Saparboy Rakhmanov HI: Chirchik State Pedagogical University 🟢OBJECTIVE: The proposed research is devoted to study ultrafast and high energy relativistic phenomena in atoms at table-top level, i.e. without using huge-cost accelerator devices and heavy ion cooling and storage facilities. This can be done by creating artificial relativistic atoms in graphene via doping their Coulomb impurities. The main focus of the proposed research is study ultrafast phenomena occurring in the interaction of artificial relativistic 1D and 2D atoms in graphene (Coulomb impurities) with external ultrashort electromagnetic pulses. In particular, electronic transitions, such as excitation and ionization, as well as electron-hole pair creation induced by the interaction of artificial atoms with external electromagnetic fields will be studied. ➡️ACCOMPLISHMENTS: - The main achievement of the research conducted within the subproject is proposing the several models of relativistic atoms and relativistic high energy phenomena that can be realized in one-atom-thick, two-dimensional quantum material, graphene: - A model for one-dimensional relativistic atom formed in graphene nanoribbon has been proposed; - A model for harmonic generation in Dirac materials has been proposed; - A sketch for experimental realization of the model in a graphene nanoribbon interacting with external optical field has been proposed. 📱https://t.me/Munis_Project 📱www.youtube.com/@MUNISProject 🌐https://wbgrants.uz
