Frustration in magnetic materials arising from competing exchange interactions can prevent
the system from adopting long-range magnetic order and can instead lead to a diverse …

Topological textures have fascinated people in different areas of physics and technologies.
However, the observations are limited in magnetic and solid-state ferroelectric systems …

This article provides a concise review of a new state of colloidal matter called nematic liquid-
crystal colloids. These colloids are obtained by dispersing microparticles of different shapes …

Skyrmions are coreless vortex-like excitations emerging in diverse condensed-matter
systems, and real-time observation of their dynamics is still challenging. Here we report the …

I started the work on liquid crystal colloids around the year 2000 as a continuation of our
experiments on forces between surfaces in liquid crystals. We were using the atomic force …

Magnetic and electric dipoles have similar symmetry and are therefore expected to exhibit
many common structures. However, despite frequent reports of various spin textures …

Dynamics of small particles, both living and inanimate, has fascinated scientists for
centuries. Learning how to control it could open technological opportunities in the …

Chirality, ubiquitous in complex biological systems, can be controlled and quantified in
synthetic materials such as cholesteric liquid crystal (CLC) systems. In this work, we study …

Fluorescent stand-alone laser particles that are implantable into biological tissues have the
potential to enable novel optical imaging, diagnosis, and therapy. Here we demonstrate …

Topology has an increasingly important role in the physics of condensed matter, quantum
systems, material science, photonics and biology, with spectacular realizations of …
