The experimental demonstration of topological dissipation in photonic resonators

So far, physicists have primarily studied topological phases in conservatively coupled systems. These are systems with dynamics that do not dissipate and a phase space that does not shrink over time. They are in stark contrast ...

New materials for quantum technologies

While conventional electronics relies on the transport of electrons, components that convey spin information alone may be many times more energy efficient. Physicists at the Technical University of Munich (TUM) and the Max ...

Observing topological magnon insulator states in a superconducting circuit

Topological states of matter are phases of matter that go beyond the Landau symmetry-breaking theory, which are characterized by topological invariants and topological edge states. Physicist David J. Thouless, in collaboration ...

Topological light: Living on the edge

(Phys.org) —Topology—the understanding of how things are connected—remains abstract, even with the popular example of doughnuts and coffee cups. This concept, esoteric as it appears, is also neat because it is the basis ...

The first non-trivial atom circuit: Progress towards an atom SQUID

(PhysOrg.com) -- Researchers from the National Institute of Standards and Technology and the University of Maryland have created the first nontrivial "atom circuit," a donut-shaped loop of ultracold gas atoms circulating ...
