Title: "Measuring the spin dynamics of single atoms with nanosecond time resolution" Abstract:Spin is a fundamental quantity in quantum mechanics. Its manifestations range from the magnet on our fridge to the magnetic-field dependent splitting of a beam of evaporated atoms in the famous Stern-Gerlach experiment. With the advent of spin-based…

Abstract:Majorana is a fermion which is its own anti-particle. Often described as half a fermion, it is expected to have novel braiding properties in 2D, but has never been observed in Nature. Proposals for realizing them in condensed matter center on making vortices in p+ip superconductors. We have found that the Majorana end states which was…
Condensed Matter Seminar "Metallic conduction and superconductivity in the t-J model: Evolution of the spin states from half filling"

Abstract: Many believe, following Anderson, that the origin of the unusual behavior of cuprate superconductors is related to the physics of the undoped phase. However, this connection has not been established theoretically. I will discuss the properties of a renormalized Hamiltonian derived recently from the t-J model, which is required to…

ABSTRACT: Circuit quantum electrodynamics (QED) allows for excellent control and measurement of the quantum mechanical properties of qubits, photons and their interactions. As a result, circuit QED is an ideal test bed to investigate the quantum nature of light. In our experiments we prepare a complete family of zero and one photon…
