Axion/Hidden-Photon Dark Matter Conversion into Condensed Matter Axion [PDF]

, 2021
The QCD axion or axion-like particles are candidates of dark matter of the universe. On the other hand, axion-like excitations exist in certain condensed matter systems, which implies that there can be interactions of dark matter particles with condensed matter axions. We discuss the relationship between the condensed matter axion and a collective spin-

Exciton diffusion in two-dimensional metal-halide perovskites

Nature Communications, 2020
The so-called two-dimensional (2D) layered perovskites possess distinct optoelectronic properties from their 3D counterparts due to their reduced dimensionality. Here Seitz et al. investigate the exciton transport dynamics in 2D perovskites and highlight

Observation of magnetic adatom-induced Majorana vortex and its hybridization with field-induced Majorana vortex in an iron-based superconductor

Nature Communications, 2021
Braiding Majorana modes is essential for topological quantum computing, but it remains difficult to find a suitable platform. Here, the authors report the evidence of hybridization between field-induced and magnetic adatom induced Majorana modes in an ...

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.

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,
