1. Three-wave mixing in Josephson travelling-wave parametric amplifiers
Abstract : This work explores possibilities of building a wide-band, quantum-limited low-noise amplifier by means of three-wave mixing (3WM) in different kinds of Josephson travelling-wave parametric amplifiers (TWPAs). We extend the theory of the continuous three-mode model to include any number of up-converted modes in the small frequency limit where the frequency dispersion is close to linear. READ MORE

2. Collective Electron Dynamics in Mesoscopic Systems
Abstract : This work is devoted to a theoretical investigation of collective electron dynamics in low dimensional materials and mesoscopic structures. A common feature of these studies is the focus on the properties of the low energy dynamics of conduction electrons. One class of studied materials is the high-Tc superconductor Nd2CuO4 and related compounds. READ MORE

3. Transport properties of Bi2Se3 Topological Insulator Nanoribbon-Superconductor hybrid junctions
Abstract : In recent years, topological superconductivity and Majorana zero-energy modes have attracted vast interest due to their potential for topologically protected quantum information processing. Hybrid devices involving a conventional s-wave superconductor (S) in proximity to a 3D Topological Insulator (TI) are expected to provide a platform for emulating and studying these phenomena.
