Quantum spin liquids may be considered'quantum disordered'ground states of spin systems,
in which zero-point fluctuations are so strong that they prevent conventional magnetic long …

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 …

Electron correlation and topology are two central threads of modern condensed matter
physics. Semiconductor moiré materials provide a highly tuneable platform for studies of …

For over 100 years, the group-theoretic characterization of crystalline solids has provided
the foundational language for diverse problems in physics and chemistry. However, the …

Since the early 1980s, most electronics have relied on the use of complementary metal–
oxide–semiconductor (CMOS) transistors. However, the principles of CMOS operation …

The discovery of the quantum spin Hall effect and topological insulators more than a decade
ago has revolutionized modern condensed matter physics. Today, the field of topological …

Electronic flat-band materials host quantum states characterized by a quenched kinetic
energy. These flat bands are often conducive to enhanced electron correlation effects and …

Topological insulators represent a new quantum state of matter which is characterized by
peculiar edge or surface states that show up due to a topological character of the bulk wave …

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 …

We analyze a two-dimensional Kondo lattice model with special emphasis on non-Hermitian
properties of the single-particle spectrum, following a recent proposal by Kozii and Fu. Our …
