Theoretical Condensed Matter Physics: Quantum Many-Body Coulomb Systems (phases of metallic Hydrogen - theory of metal-insulator transitions - Wigner crystals and paired spin-singlet phases in a magnetic field - universal properties of quantal charged systems); Generalized pairing in the condensed state (microscopic Superconductivity vs Fermionic paired supersolids); Quasicrystals (novel transmission properties of Fibonacci chains and Penrose networks); Nanoscale Physics in Aharonov-Bohm Configurations (electron-hole interactions in quantum nanorings); Quantum Hall Systems (thermodynamic magnetic properties in heterostructures and properties beyond de Haas-van Alphen oscillations); Gauge transformations and Physics beyond the standard Dirac phase factor; generic Topological aspects of Condensed Matter Physics (especially in Graphene and in Topological Insulators, and most recently in Weyl semimetals).
