Electronic nature of charge density wave and electron-phonon coupling in kagome superconductor KV3Sb5

Nature Communications, 2022
The impact of the charge density wave (CDW) state to the electronic structure in the Kagome superconductors AV3Sb5 remains unclear. Here, the authors observe CDW-induced Fermi surface reconstruction with a strongly anisotropic CDW gap and signatures of ...

Counting Rules of Nambu-Goldstone Modes [PDF]

, 1956
When global continuous symmetries are spontaneously broken, there appear gapless collective excitations called Nambu-Goldstone modes (NGMs) that govern the low-energy property of the system. The application of this famous theorem ranges from high-energy,

A robust and tunable Luttinger liquid in correlated edge of transition-metal second-order topological insulator Ta2Pd3Te5

Nature Communications, 2023
The interplay between topology and interaction always plays an important role in condensed matter physics and induces many exotic quantum phases, while rare transition metal layered material (TMLM) has been proved to possess both.

Notes on topological insulators [PDF]

, 2016
This paper is a survey of the $\mathbb{Z}_2$-valued invariant of topological insulators used in condensed matter physics. The $\mathbb{Z}$-valued topological invariant, which was originally called the TKNN invariant in physics, has now been fully ...

Phase diagram of Bi2Sr2CaCu2O8+δ revisited

Nature Communications, 2018
The doping level of cuprate superconductors is usually difficult to determine. Here, Drozdov et al. report spectroscopic studies of in-situ modified Bi2Sr2CaCu2O8+δ , exploring not only the superconducting dome but also the previously inaccessible, non ...
