Research by Antonio Castro Neto

grapheme

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.
