We review the recent, mainly theoretical, progress in the study of topological nodal line
semimetals in three dimensions. In these semimetals, the conduction and the valence bands …

The realization of Dirac and Weyl physics in solids has made topological materials one of
the main focuses of condensed matter physics. Recently, the topic of topological nodal line …

We revisit the possibility that the stochastic common-spectrum process recently detected by
the NANOGrav pulsar timing array experiment could be due to primordial gravitational …

Over the past decade, topological materials—in which the topology of electron bands in the
bulk material leads to robust, unconventional surface states and electromagnetism—have …

Topological electronic materials such as bismuth selenide, tantalum arsenide and sodium
bismuthide show unconventional linear response in the bulk, as well as anomalous gapless …

Nowadays, it is recognized that semiconductors are prospective candidates for promising
thermoelectric materials and the gapless topological phonon modes can result in a high …

Recently, a new “type-II” Weyl fermion, which exhibits exotic phenomena, such as an angle-
dependent chiral anomaly, was discovered in a new phase of matter where electron and …

Precise measurements of the cosmic microwave background (CMB) power spectrum are in
excellent agreement with the predictions of the standard Λ CDM cosmological model …

We study the band topology and the associated linking structure of topological semimetals
with nodal lines carrying Z 2 monopole charges, which can be realized in three-dimensional …

The direct detection of gravitational waves (GWs) from merging binary black holes and
neutron stars marks the beginning of a new era in gravitational physics, and it brings forth …
