Thouless pumping provides one of the simplest manifestations of topology in quantum
systems and has attracted a lot of recent interest, both theoretically and experimentally …

Atomtronics deals with matter-wave circuits of ultracold atoms manipulated through
magnetic or laser-generated guides with different shapes and intensities. In this way, new …

Rapidly growing demands for fast information processing have launched a race for creating
compact and highly efficient optical devices that can reliably transmit signals without losses …

The topological protection of wave transport, originally observed in the context of the
quantum Hall effect in two-dimensional electron gases, has been shown to apply broadly to …

Topological photonics is a rapidly emerging field of research in which geometrical and
topological ideas are exploited to design and control the behavior of light. Drawing …

Geometric properties of wave functions can explain the appearance of topological invariants
in many condensed-matter and quantum systems. For example, topological invariants …

One-dimensional topological pumping of matter waves in two overlaid optical lattices
moving with respect to each other is considered in the presence of attractive nonlinearity. It …

We consider theoretically the nonlinear quantized Thouless pumping of a Bose-Einstein
condensate loaded in two-dimensional dynamical optical lattices. We encountered three …

Quantum transport between distant nodes that is robust to experimental imperfections is
essential for quantum information processing. Here we experimentally demonstrate efficient …

Quantized adiabatic transport can occur when a system is slowly modulated over time. In
most realizations, however, the efficiency of such transport is reduced by unwanted …
