The last few years have seen an explosion of interest in hydrodynamic effects in interacting
electron systems in ultra-pure materials. One such material, graphene, is not only an …

Extraordinary electron systems can be generated at well-defined interfaces between
complex oxides. In recent years, progress has been achieved in exploring and making use …

Three-dimensional (3D) Dirac point, where two Weyl points overlap in momentum space, is
usually unstable and hard to realize. Here we show, based on the first-principles …

External control of the conductivity of correlated oxides is one of the most promising
schemes for realizing energy-efficient electronic devices. Vanadium dioxide (VO2), an …

Inspired by the great development of graphene, more and more research has been
conducted to seek new two-dimensional (2D) materials with Dirac cones. Although 2D Dirac …

Although phase transitions have long been a centerpiece of condensed matter materials
science studies, a number of recent efforts focus on potentially exploiting the resulting …

Computer simulations within the framework of density functional theory are performed to
study the electronic, dynamic, elastic, magnetic, and thermoelectric properties of a newly …

We report the observation of highly anisotropic Dirac fermions in a Bi square net of SrMnBi
2, based on a first-principles calculation, angle-resolved photoemission spectroscopy, and …

A great obstacle for practical applications of the quantum anomalous Hall (QAH) effect is the
lack of suitable QAH materials (Chern insulators) with a large non-trivial band gap, room …

We develop a tight-binding model description of semi-Dirac electronic spectra, with highly
anisotropic dispersion around point Fermi surfaces, recently discovered in electronic …
