Magnetic topological materials represent a class of compounds with properties that are
strongly influenced by the topology of their electronic wavefunctions coupled with the …

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

Topological electronic materials, such as topological insulators, are distinct from trivial
materials in the topology of their electronic band structures that lead to robust …

Topological semimetals (TSMs) are characterized by bulk band crossings in their electronic
structures, which are expected to give rise to gapless electronic excitations and topological …

The physics of quantum materials is dictated by many-body interactions and mathematical

Here we report the observation of bulk superconductivity in single crystals of the two-
dimensional kagome metal KV 3 Sb 5. Magnetic susceptibility, resistivity, and heat capacity …

As spins move through a chiral electric field, the resulting spin current can acquire chirality
through a spin–orbit interaction. Such spin currents are highly useful in creating spin–orbit …

A review is given on the foundations and applications of non-Hermitian classical and
quantum physics. First, key theorems and central concepts in non-Hermitian linear algebra …
