The physics of quantum materials is dictated by many-body interactions and mathematical
concepts such as symmetry and topology that have transformed our understanding of matter …

Optical metamaterials have presented an innovative method of manipulating light.
Hyperbolic metamaterials have an extremely high anisotropy with a hyperbolic dispersion …

Flash sintering (FS) is an energy efficient sintering technique involving electrical Joule
heating, which allows very rapid densification (< 60 s) of particulate materials. Since the first …

This review focuses on the superconducting properties of MgB 2 that are relevant for power
applications. The reversible mixed state parameters are the most important, since they …

We report a significant enhancement of the upper critical field H c2 of different MgB 2
samples alloyed with nonmagnetic impurities. By studying films and bulk polycrystals with …

We review the current situation in the theory of superconducting and transport properties of
MgB2. First principle calculations of the electronic structure and electron–phonon coupling …

The layered lithium borocarbide LiBC, isovalent with and structurally similar to the
superconductor MgB 2, is an insulator due to the modulation within the hexagonal layers …

Abstract The Ginzburg-Landau functional for a two-gap superconductor is derived within the
weak-coupling BCS model. The interaction between the two condensates is described by a …

The two gaps in a two-band clean s-wave superconductor are evaluated self-consistently
within the quasiclassical Eilenberger weak-coupling formalism with two in-band and one …

A class of strongly anisotropic materials having their principal elements of dielectric
permittivity or magnetic permeability tensors of opposite signs, so-called indefinite or …
