Many materials crystallize in structure types that feature a square net of atoms. While these
compounds can exhibit many different properties, some members of this family are …

We present a systematic study of the low-energy electrodynamics of the magnetic FeSn
kagome metal, which hosts both topological (Dirac) and non-trivial states. Our results reveal …

We report our investigations on the effects of pressure on the electronic and magnetic
properties of magnetic Dirac semimetal EuMnBi 2 by using electrical transport, synchrotron x …

We investigate the physical properties of massive Dirac fermions in SrMnSb 2 using
transport, specific heat, electronic structure calculations, and Shubnikov-de Haas (SdH) …

Photoexcited carriers in three-dimensional topological insulators (3D TIs) decay rapidly
through the electron-electron and electron-phonon scattering. While most studies focus on …

We report the growth of La2O2Bi epitaxial thin films for the first time by utilizing multilayer
solid-phase epitaxy. The films were grown only on a MgO (001) substrate among several …

We have investigated the temperature-and field-variation of electronic state for the Dirac
semimetal of EuMnBi 2 by means of optical spectroscopy and theoretical calculation. The …

The newly designed A MnBi 2 (A= alkaline as well as rare-earth atom) materials based on
quasi-two-dimensional bismuth layers provide a suitable playground to address the physics …

We investigate the temperature-dependent infrared spectroscopy of SrMnSb 2, which is a
semimetal with multiple Fermi surfaces. A notable blue shift of the plasma minimum in …

Correlated Dirac semimetal phases emerge in lightly doped (Tb-or La-doped) Mott insulator
Sr 2 Ir O 4, where ad-wave symmetry-breaking order underlying a pseudogap plays a crucial …
