Computing topological invariants without inversion symmetry
We consider the problem of calculating the weak and strong topological indices in noncentrosymmetric time-reversal (T ) invariant insulators. In 2D we use a gauge corresponding to hybrid Wannier functions that are maximally localized in one dimension. Although this gauge is not smoothly defined on the two torus, it respects the T symmetry of the system and allows for a definition of the Z2 inva...
متن کاملSuperconductivity in ferromagnetic metals and in compounds without inversion centre
The symmetry properties and the general overview of the superconductivity theory in the itinerant ferromagnets and in materials without space parity are presented. The basic notions of unconventional superconductivity are introduced in broad context of multiband superconductivity which is inherent property of ferromanetic metals or metals without centre of inversion.
متن کاملParamagnetic limit of superconductivity in a crystal without inversion center
The theory of paramagnetic limit of superconductivity in metals without inversion center is developed. There is in general the paramagnetic suppression of superconducting state. The effect is strongly dependent on field orientation in respect to crystal axes. The reason for this is that the degeneracy of electronic states with opposite momenta k and −k forming of Cooper pairs is lifted by magne...
متن کاملElectron Spin Dynamics in Semiconductors without Inversion Symmetry
Recent consideration of spin based quantum computation, optical switches, magnetic memory cells, etc. [1] mandates an improved understanding of spin dynamics and, in particular, the spin relaxation rate [2]. The most promising materials for device purposes, III-V and II-VI compounds, have been shown [3] to have spin relaxation rates dominated by the D’yakonov-Perel’ (DP) mechanism at moderate t...
متن کاملLearning from data to design functional materials without inversion symmetry
Accelerating the search for functional materials is a challenging problem. Here we develop an informatics-guided ab initio approach to accelerate the design and discovery of noncentrosymmetric materials. The workflow integrates group theory, informatics and density-functional theory to uncover design guidelines for predicting noncentrosymmetric compounds, which we apply to layered Ruddlesden-Po...
