Dr. hab. Mykhailo Solovan Faculty of Physics and Astronomy, AMU Poznań   Abstract: Perovskite and organic solar cells are promising for lightweight and flexible photovoltaics, including applications in space. Their radiation stability is important for these applications. In this talk, I will discuss the effects of proton, electron, and ultraviolet irradiation on guanidinium-containing perovskite solar […]

Prof. Yuji Kuwahara Osaka University–RIKEN Center for Science and Technology, The University of Osaka, Japan   Abstract: Scanning tunneling microscopy (STM) provides a powerful tool for investigating the atomic structure and electronic properties of nanomaterials and nanostructures on the surface. By extending the capabilities of this STM, we have developed several novel STM-based techniques for […]

Dr Andy Chia Centre for Quantum Technologies, Singapore   Abstract: Several important dynamical systems are in ℝ2, defined by the pair of differential equations (𝑥',𝑦')=(𝑓⁡(𝑥,𝑦),𝑔⁡(𝑥,𝑦)). A question of fundamental importance is how such systems might behave quantum mechanically. In developing quantum theory, Dirac and others realized that classical Hamiltonian systems can be mapped to their […]
