The concept of metamaterials originates from the proposal of left-hand materials with
negative refractive index, followed by which, varieties of metamaterials with kinds of fantastic …

This paper reviews recent experimental and theoretical progress concerning many-body
phenomena in dilute, ultracold gases. It focuses on effects beyond standard weak-coupling …

In 1978, while I was a postdoctoral fellow at MIT, I read a paper by Art Ashkin (1978) in
which he described how one might slow down an atomic beam of sodium using the radiation …

Transport phenomena in spatially periodic systems far from thermal equilibrium are
considered. The main emphasis is put on directed transport in so-called Brownian motors …

The Fermi-Hubbard model is a key concept in condensed matter physics and provides
crucial insights into electronic and magnetic properties of materials. Yet, the intricate nature …

Publisher Summary This chapter discusses the orbital angular momentum of light, outlines
the theoretical basis for the orbital angular momentum of beams within the paraxial …

The term 'photonics' describes a technology whereby data transmission and processing
occurs largely or entirely by means of photons. Photonic crystals are microstructured …

Unter allen Messgrößen ist die Frequenz diejenige, die mit dem höchsten Grad an
Sicherheit bestimmt werden kann. Damit sind auch präzise Messungen von anderen …

We study the ground states of cold atoms in the tight-binding bands built from p orbitals on a
two dimensional honeycomb optical lattice. The band structure includes two completely flat …
