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,

Accurate Semilocal Density Functional for Condensed-Matter Physics and Quantum Chemistry. [PDF]
Physical Review Letters, 2016 Most density functionals have been developed by imposing the known exact constraints on the exchange-correlation energy, or by a fit to a set of properties of selected systems, or by both.

Nematic Fermi Fluids in Condensed Matter Physics [PDF]
, 2010 Correlated electron fluids can exhibit a startling array of complex phases, among which one of the more surprising is the electron nematic, a translationally invariant metallic phase with a spontaneously generated spatial anisotropy.

Para-hydrodynamics from weak surface scattering in ultraclean thin flakes
Nature Communications, 2023 Electron hydrodynamics typically emerges in electron fluids with a high electron–electron collision rate. However, new experiments with thin flakes of WTe2 have revealed that other momentum-conserving scattering processes can replace the role of the ...

Searches for light dark matter using condensed matter systems [PDF]
Reports on progress in physics. Physical Society, 2021 Identifying the nature of dark matter (DM) has long been a pressing question for particle physics. In the face of ever-more-powerful exclusions and null results from large-exposure searches for TeV-scale DM interacting with nuclei, a significant amount ...

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 ...
