The structure of our material world is characterized by a large hierarchy of length scales that
determines material properties and functions. Increasing spatial resolution in optical imaging …

Functional oxides are an untapped resource for futuristic devices and functionalities. These
functionalities can range from high temperature superconductivity to multiferroicity and novel …

The motion of atoms in a solid always responds to cooling or heating in a way that is
consistent with the symmetry of the given space group of the solid to which they belong …

We experimentally demonstrate a class of tractor beams created by coherently superposing
coaxial Bessel beams. These optical conveyors have periodic intensity variations along their …

The new 182 gold supernova Ia data, the baryon acoustic oscillation measurement and the
shift parameter determined from the Sloan Digital Sky Survey, and the three-year Wilkinson …

The dark energy component of the Universe is often interpreted either in terms of a
cosmological constant or as a scalar field. A generic feature of the scalar field models is that …

The floating-zone method and high-pressure synthesis have been used to obtain the
hexagonal and the perovskite R Mn O 3 (R= Y, Ho, Er, Tm, Yb, Lu) compounds. We have …

We demonstrate both experimentally and theoretically that a colloidal sphere trapped in a
static optical tweezer does not come to equilibrium, but rather reaches a steady state in …

We have performed high-resolution neutron diffraction and inelastic neutron scattering
experiments in the frustrated multiferroic hexagonal compounds R MnO 3 (R= Ho, Yb, Sc, Y) …

Multiferroic materials are those which possess both ferroelectric and ferromagnetic
properties. Clearly, there is a contradiction here since ferromagnetism requires d-electrons …
