The coherent bunching of anyons and their dissociation was observed in an interference experiment. 

An interferometer design allows systematic investigation of the anyonic statistics of bulk fractional quantum Hall states.

Dynamic nuclear polarization is the transfer of electronic angular momentum to nuclear spins and is a potential route for coherently manipulating spin in quantum information. Here, the authors show that spin–orbit coupling can quench dynamic nuclear polarization in a gallium arsenide quantum dot.

The accepted picture of transport in the fractional quantum Hall effect regime is that neutral modes are present only in hole-conjugate fractional states. Inoue et al.show the presence of upstream neutral modes and energy transport through the bulk in all tested non-hole-conjugate fractional states.

In two-dimensional systems, swapping the position of two indistinguishable particles twice—braiding them—reveals their exchange statistics. Now, a Mach–Zehnder interferometer accomplishes this for anyonic fractional quantum Hall states.

The boundaries of fractional quantum Hall states can host multiple, interacting one-dimensional edge modes, which test our understanding of strongly interacting systems. Here the authors observe the edge-mode equilibration transition that was predicted for the ν=2/3 fractional quantum Hall state.

Helical modes are induced in a high-mobility two-dimensional electron gas without strong spin–orbit coupling. This platform provides a versatile playground for investigating compounded quantum Hall edge states.

Understanding the transfer of heat currents, specifically, neutral heat modes which do not carry net charge, is of great interest. Here, the authors study the transmission of upstream neutral modes through a quantum point contact in order to render the relative spatial distribution of these chargeless modes.

Two challenging questions related to the quantum Hall effect (QHE) are how edge reconstruction works and where the current flows. A new model now gives the answer for two types of QHE states — two separate downstream chiral edge channels are involved.

The spin state of two electrons in a double well is a promising qubit. Now, such qubits can be arbitrarily rotated around two different axes by applying a magnetic field of different magnitude to each electron. This can be done in nanoseconds, before the stored information is lost.

The lipid transporter FATP2 reprograms neutrophils to polymorphonuclear myeloid-derived suppressor cells by mediating the uptake of arachidonic acid and promoting the synthesis of prostaglandin E₂.

Electron spins in semiconductor structures are quantum bits with good prospects, but the information stored in the spin states tends to degrade quickly owing to interactions with nuclei in the host material. A study of GaAs quantum dots now provides a fuller understanding of this memory loss and how it can be suppressed. Quantum-memory times exceeding 200 μs are demonstrated, two orders of magnitude longer than previously reported for this system.

An extremely large, negative refractive index is produced in a two-dimensional electron gas by exploiting its kinetic inductance, which is a manifestation of acceleration of the electrons by electromagnetic fields.

Measuring quantum entanglement remains a demanding task. The authors introduce two functions to quantify entanglement induced by fermionic or bosonic statistics, in transport experiments. Both functions, in theory and experiment, are remarkably resilient against the nonuniversal effects of interactions.

A simple experimental method identifies the statistical phase of highly diluted abelian anyons weakly partitioned in fractional quantum Hall states and reveals their braiding statistics.

Wigner molecules, or correlated localized electron states, has been reported in semiconductor quantum dots, but their interaction with environment has been less explored. Here the authors use the spin multiplet structure of a three-electron Wigner molecule to enhance and control dynamic nuclear polarization.

Shot noise has traditionally been used to measure the charge of quasiparticles in a variety of mesoscopic systems. However, at sufficiently low temperatures, this usual notion tends to break down for fractional quantum Hall effect states.

The transport behaviour of counter-propagating edge modes in the hole-conjugate fractional quantum Hall state is not fully understood. Here, by combining local noise thermometry and thermal conductance measurements, the authors show the absence of thermal equilibration on the edge at macroscopic distances.

We measure efficient heat conductance through the electrically insulating quantum Hall bulk and propose a theoretical model based on the role played by the localized states.

Measurements of the thermal Hall conductance in the first excited Landau level of the quantum Hall effect show the existence of a state with non-Abelian excitations.

Careful thermal transport measurements identify the topological nature of transverse thermal conductance in the fractional quantum Hall regime.

Quasiparticles in strongly interacting fractional quantum Hall systems carry heat according to the same quantization of thermal conductance as for particles in non-interacting systems.
