Optical levitation of fluorescent silicon carbide nanoparticles in vacuum

Seyed Khalil Alavi, Cheng-I Ho, Iuliia Neumann +4

Levitated optomechanics is an emerging field in quantum science that explores the quantum motion of mesoscopic particles levitated in a vacuum. Expanding this approach to particles…

Strong and Weak Three-Dimensional Topological Insulators Probed by Surface Science Methods

Markus Morgenstern, Christian Pauly, Jens Kellner +12

We review the contributions of surface science methods to discover and improve 3D topological insulator materials, while illustrating with examples from our own work. In particular…

Electronic Structure of the Dark Surface of the Weak Topological Insulator Bi14Rh3I9

Christian Pauly, Bertold Rasche, Klaus Koepernik +6

The compound Bi14Rh3I9 consists of ionic stacks of intermetallic [(Bi4Rh)3I]2+ and insulating [Bi2I8]2- layers and has been identified to be a weak topological insulator. Scanning…

Correlation between topological band character and chemical bonding in a -based family of insulators

Bertold Rasche, Anna Isaeva, Michael Ruck +3

Recently the presence of topologically protected edge-states in BiRhI was confirmed by scanning tunnelling microscopy consolidating this compound as a weak 3D topolo…

Sub-nm wide electron channels protected by topology

Christian Pauly, Bertold Rasche, Klaus Koepernik +11

Helical locking of spin and momentum and prohibited backscattering are the key properties of topologically protected states. They are expected to enable novel types of information…

Stacked topological insulator built from bismuth-based graphene sheet analogues

Bertold Rasche, Anna Isaeva, Michael Ruck +7

Commonly materials are classified as either electrical conductors or insulators. The theoretical discovery of topological insulators (TIs) in 2005 has fundamentally challenged this…
