Query: Strongly Interacting Holes in Ge/Si Nanowires   We consider holes confined to Ge/Si core/shell nanowires subject to strong
Rashba spin-orbit interaction and screened Coulomb interaction. Such wires can,
for instance, serve as host systems for Majorana bound states. Starting from a
microscopic model, we find that the Coulomb interaction strongly influences the
properties of experimentally realistic wires. To show this, a Luttinger liquid
description is derived based on a renormalization group analysis. This
description in turn allows to calculate the scaling exponents of various
correlation functions as a function of the microscopic system parameters. It
furthermore permits to investigate the effect of Coulomb interaction on a small
magnetic field, which opens a strongly anisotropic partial gap.
