The physics of quantum materials is dictated by many-body interactions and mathematical
concepts such as symmetry and topology that have transformed our understanding of matter …

The Kitaev model is an exactly solvable S= 1/2 spin model on a 2D honeycomb lattice, in
which the spins fractionalize into Majorana fermions and form a topological quantum spin …

The first-principles band theory paradigm has been a key player not only in the process of
discovering new classes of topologically interesting materials, but also for identifying salient …

The exactly solvable Kitaev model on the honeycomb lattice has recently received
enormous attention linked to the hope of achieving novel spin-liquid states with …

Geometrical constraints to the electronic degrees of freedom within condensed-matter
systems often give rise to topological quantum states of matter such as fractional quantum …

Doping mobile carriers into ordinary semiconductors such as Si, GaAs, and ZnO was the
enabling step in the electronic and optoelectronic revolutions. The recent emergence of a …

Materials composed of two dimensional layers bonded to one another through weak van der
Waals interactions often exhibit strongly anisotropic behaviors and can be cleaved into very …

Recently, the effects of spin-orbit coupling (SOC) in correlated materials have become one
of the most actively studied subjects in condensed matter physics, as correlations and SOC …

Describing all aspects of the physics of transition metal compounds, this book provides a
comprehensive overview of this unique and diverse class of solids. Beginning with the basic …

We examine the role of spin-orbit coupling in the electronic structure of α-RuCl 3, in which
Ru ions in 4 d 5 configuration form a honeycomb lattice. Our x-ray absorption spectroscopy …
