Research by Antonio Castro Neto


Professor Castro Neto has broad interests in condensed matter theory research ranging from decoherence in quantum open systems (with applications to quantum computation and NEMS – Nanoelectromechanical systems), and quantum magnetism in ordered and disordered itinerant magnets, to high temperature superconductors (HTc). Some of the subjects studied by Prof. Castro Neto’s group are: the nature of inhomogeneous states (such as stripes) in HTc cuprate oxides; the interplay between quantum fluctuations, disorder, and dissipation in metallic magnets and the existence of Griffiths-McCoy singularities, responsible for singular behavior in the magnetic response of these systems at low temperatures (such as U and Ce intermetallics); the frustration of decoherence in open quantum systems; the interplay of dissipation and disorder in the physics quantum ferromagnets (such as UCu2Si(2-x)Ge(x)); the ferromagnetism and metal-insulator transitions in systems with very small electronic densities (such as Eu(1-x)Ca(x)B6); the study of strongly-correlated systems in finite geometries, such as in nano-structures; the renormalization group analysis of superconductivity in electron-boson systems. More recently, Prof. Castro Neto’s group, using field theoretical methods, has studied the electronic properties in two-dimensional (graphene) and three-dimensional (graphite) carbon based materials.
