The quantum Hall (QH) effect, quantized Hall resistance combined with zero longitudinal
resistance, is the characteristic experimental fingerprint of Chern insulators—topologically …

Magnetic skyrmions have attracted enormous research interest since their discovery a
decade ago. The non-trivial real-space topology of these nano-whirls leads to fundamentally …

Quantum geometric properties of Bloch wave functions in solids, that is, Berry curvature and
the quantum metric, are known to significantly influence the ground-and excited-state …

The accuracy and efficiency of electronic-structure methods to understand, predict and
design the properties of materials has driven a new paradigm in research. Simulations can …

Over the past twenty-five years, mathematical concepts associated with geometric phases
have come to occupy a central place in our modern understanding of the physics of …

Abstract The Dirac and Weyl semimetals are unusual materials in which the nodes of the
bulk states are protected against gap formation by crystalline symmetry,,,. The chiral …

The interplay between chirality and topology nurtures many exotic electronic properties. For
instance, topological chiral semimetals display multifold chiral fermions that manifest …

Topological Hall effect (THE) and its inverse effect (skyrmion Hall effect) generally occurs in
magnetic materials with topological properties, as a consequence of nonuniform and …

Q uantum ESPRESSO is an integrated suite of open-source computer codes for quantum
simulations of materials using state-of-the-art electronic-structure techniques, based on …

The advent of visible-infrared laser pulses carrying a substantial fraction of their energy in a
single field oscillation cycle has opened a new era in the experimental investigation of …
