Artificial gauge fields are currently realized in a wide range of physical settings. This
includes solid-state devices but also engineered systems, such as photonic crystals …

Geometric phases that characterize the topological properties of Bloch bands play a
fundamental role in the band theory of solids. Here we report on the measurement of the …

We explore the nonequilibrium response of Chern insulators. Focusing on the Haldane
model, we study the dynamics induced by quantum quenches between topological and …

Detecting topological order in cold-atom experiments is an ongoing challenge, the
resolution of which offers novel perspectives on topological matter. In material systems …

The realization and detection of topological phases with ultracold atomic gases is at the
frontier of current theoretical and experimental research. Here, we identify cold atoms in …

What is" topological" about topological quantum states? How many types of topological
quantum phases are there? What is a zero-energy Majorana mode, how can it be realized in …

The Landau-Zener (LZ) transition is one of the most fundamental phenomena in quantum
dynamics. It describes nonadiabatic transitions between quantum states near an avoided …

Quantum systems can show qualitatively new forms of behavior when they are driven by fast
time-periodic modulations. In the limit of large driving frequency, the long-time dynamics of …

In this Rapid Communication we propose realistic schemes to realize topologically nontrivial
Floquet states by shaking optical lattices, using both the one-dimensional lattice and two …

We propose a scheme to measure the quantized Hall conductivity of an ultracold Fermi gas
initially prepared in a topological Chern insulating phase and driven by a constant force. We …
