The discovery of the quantum Hall effect (QHE) marked a turning point in condensed-matter
physics. The measurement of the Hall resistance showed that electronic resistance could be …

The discovery of the quantized and fractional Quantum Hall Effect phenomena is among the
most important physics findings in the latter half of this century. The precise quantization of …

Abstract The Quantum Hall Effect (QHE) is one of the most remarkable condensed-matter
phenomena discovered in the second half of the 20 th century. It rivals superconductivity in …

The quantum anomalous Hall (QAH) effect has attracted extensive attention due to time-
reversal symmetry broken by a staggered magnetic flux emerging from ferromagnetic …

Quantum anomalous Hall (QAH) insulator is a topological phase which exhibits chiral edge
states in the absence of magnetic field. The celebrated Haldane model is the first example of …

Today, more than 20 years after the discovery of the quantum Hall effect, the number of
publications in this field, at more than one paper per day, is still increasing. This remarkable …

The quantum anomalous Hall effect is defined as a quantized Hall effect realized in a system
without an external magnetic field. The quantum anomalous Hall effect is a novel …

Physicists looking for challenging problems with practical implications should try materials
science, which starts where conventional solid-state physics stops. Many important physical …

The quantum Hall effect (QHE), and devices reliant on it, will continue to serve as the
foundation of the ohm while also expanding its territory into other SI derived units. The …

A study of the temperature evolution of the recently discovered reflection symmetry of the
diagonal resistivity, ϱxx, near quantum Hall-to-insulator transitions, is presented. The data is …
