Gauge-invariant absolute quantification of electric and magnetic multipole densities in crystals
R. Winkler, U. Zülicke
Electric and magnetic multipole densities in crystalline solids, including the familiar electric dipole density in ferroelectrics and the magnetic dipole density in ferromagnets, a…
Time inversion symmetry in the Dirac and Schrödinger-Pauli theories
R. Winkler, U. Zülicke
The Schrödinger-Pauli theory is generally believed to give a faithful representation of the nonrelativistic and weakly relativistic limit of the Dirac theory. However, the Schrödin…
Andreev bound states at boundaries of polarized 2D Fermi superfluids with s-wave pairing and spin-orbit coupling
Kadin Thompson, Joachim Brand, Ulrich Zülicke
A topological superfluid phase characterized by an emergent chiral-p-wave pair potential is expected to form in a two-dimensional Fermi superfluid subject to s-wave pairing, spin-o…
Triplet character of 2D-fermion dimers arising from -wave attraction via spin-orbit coupling and Zeeman splitting
Ulrich Ebling, Ulrich Zülicke, Joachim Brand
We theoretically study spin- fermions confined to two spatial dimensions and experiencing isotropic short-range attraction in the presence of both spin-orbit coupling and Zeem…
Spherical topological-insulator nanoparticles: Quantum size effects and optical transitions
L. Gioia, M. G. Christie, U. Zülicke +2
We have investigated the interplay between band inversion and size quantization in spherically shaped nanoparticles made from topological-insulator (TI) materials. A general theore…
Chiral twodimensional p-wave superfluid from s-wave pairing in the BEC regime
K. Thompson, J. Brand, U. Zülicke
Twodimensional spin-orbit-coupled Fermi gases subject to s-wave pairing can be driven into a topological phase by increasing the Zeeman spin splitting beyond a critical value. In t…
