An archetypical layered topological insulator Bi _2 Se _3 becomes superconductive upon doping with Sr, Nb or Cu. Superconducting properties of these materials in the presence of in-plane magnetic field demonstrate spontaneous symmetry breaking: 180 ^

The structure of the layered SrxBi2Se3 crystals characterized by the nematic superconductivity has been studied. It is shown that the higher the degree of the superconducting and structural nematicity, the stronger the deviation of the block boundary

A structural reason for superconductivity in a Cu-, Sr-, or Nb-atom-doped Bi2Se3 topological insulator is still unclear. To understand this reason, a codoping approach has been developed and BaySrxBi2Se3 single crystals with different x and y values
We have studied spectral evolution of the $E_u^1$ phonon line of a topological insulator Bi$_{2-x}$Sr$_x$Se$_3$ with temperature. Unlike the Raman-active phonons, the $E_u^1$ mode demonstrates softening upon cooling the crystal, and the corresponding

Nematic superconductors are characterized by an apparent crystal symmetry breaking that results in the anisotropy of the in-plane upper critical magnetic field $H_{c2}$. The symmetry breaking is usually attributed to the strain of the crystal lattice

Topological superconductivity is an exotic phase of matter in which the fully gapped superconducting bulk hosts gapless Majorana surface states protected by topology. Intercalation of copper, strontium, or niobium between the quintuple layers of the

Selective excitation of coherent high-amplitude vibrations of atoms in a solid can induce exotic nonequilibrium states, in which the character of interactions between electronic, magnetic and lattice degrees of freedom is considerably altered and the

In this paper, we present novel experimental evidence for the odd-parity nematic superconductivity in high-quality single crystals of doped topological insulator ${\mathrm{Sr}}_{x}{\mathrm{Bi}}_{2}{\mathrm{Se}}_{3}$. The x-ray diffraction shows that

The magnetotransport in Bi2Se3 thin films with magnetic Eu dopants is studied within the range of low applied magnetic fields. With the increase in the doping level, the saturation of the dephasing length on cooling is observed. This can be related t
