Topological characterization of periodically-driven quantum systems
Takuya Kitagawa, Erez Berg, Mark Rudner +1
Topological properties of physical systems can lead to robust behaviors that are insensitive to microscopic details. Such topologically robust phenomena are not limited to static s…
Exploring Topological Phases With Quantum Walks
Takuya Kitagawa, Mark S. Rudner, Erez Berg +1
The quantum walk was originally proposed as a quantum mechanical analogue of the classical random walk, and has since become a powerful tool in quantum information science. In this…
Phase sensitive measurements of order parameters for ultracold atoms through two particles interferometry
Takuya Kitagawa, Alain Aspect, Marcus Greiner +1
Nontrivial symmetry of order parameters is crucial in some of the most interesting quantum many-body states of ultracold atoms and condensed matter systems. Examples in cold atoms…
