We propose a scheme to generate pairs of time-reversal invariant parafermions. Our setup
consists of two quantum wires with Rashba spin-orbit interactions coupled to an s-wave …

Here we review recent progress in cooling micro-/nanoelectronic devices significantly below
10 mK. A number of groups worldwide are working to produce sub-millikelvin on-chip …

We propose a scheme to induce Z 3 parafermion modes, exotic zero-energy bound states
that possess non-Abelian statistics. We consider a minimal setup consisting of a bundle of …

Spin–momentum locking in a semiconductor device with strong spin–orbit coupling (SOC) is
thought to be an important prerequisite for the formation of Majorana bound states,,. Such a …

We investigate the influence of nuclear spins on the resistance of helical edge states of two-
dimensional topological insulators (2DTIs). Via the hyperfine interaction, nuclear spins allow …

The electrons in the edge channels of two-dimensional topological insulators can be
described as a helical Tomonaga-Luttinger liquid. They couple to nuclear spins embedded …

We present a simple on-chip electronic thermometer with the potential to operate down to 1
mK. It is based on transport through a single normal-metal–superconductor tunnel junction …

Non-Abelian quasiparticles have been predicted to exist in a variety of condensed matter
systems. Their defining property is that an adiabatic braid between two of them results in a …

We present measurements of the electron temperature using gate-defined quantum dots
formed in a GaAs 2D electron gas in both direct transport and charge sensing mode. Decent …

We present silver-epoxy filters combining excellent microwave attenuation with efficient wire
thermalization, suitable for low temperature quantum transport experiments. Upon …
