A new experiment shows that entangled electron pairs can be spatially split into different arms of a carbon nanotube. Is a nanotube quantum teleporter on the horizon?

A method combining a traditional laser pump-probe experiment with the detection of high-frequency sound and thermal waves reveals the microscopically bumpy interface between two apparently smooth surfaces.

Calculations indicate that germanium telluride nanoplatelets above a certain size should exhibit a reversible toroidal spin ground state, control over which could be useful for computing applications.

Under certain conditions, nanowires that form when a metal is deposited on a surface are primarily made of the substrate.

A proposal for how to design a superconducting qubit solves the problem of decoherence caused by randomly charged impurities.

First-principles calculations explore how magnetic interactions impede the formation of atomically thin wires.

Researchers measured how the electrical conductance between two ${\text{C}}_{60}$ molecules depends on their distance and orientation.

A new approach to reduce spherical and chromatic aberration in electron microscopy allows for low-energy imaging of single-layer boron nitride, a novel 2D nanostructure that is analogous to graphene.

A theoretical analysis of recent experiments suggests that a key feature of a topological quantum computer—the unusual statistics of quasiparticles in the quantum Hall effect—may finally have been observed.

Rotating electric fields can power the flow of water along a nanochannel.

A microscopic study of magnetic nanoislands on a surface challenges the widely held view that all atoms in a relaxing nanoparticle flip their spins in unison.

Fullerenes enclosing a metallic complex are found to form an ordered array with preferred alignment on a copper surface.

Quantum states in disordered solids are characterized by wild spatial fluctuations. As a result, the behavior of a single typical wave function differs markedly from the ensemble average.

The complete geometry of ${\text{C}}_{60}$ molecules adsorbed on a silver surface has been determined for the first time with low-energy electron diffraction.

A molecular network on a copper surface serves as a template for growing nanowires of uniform size from a range of metals.

With a high-energy electron beam, it is possible to carve out atomically thin strands of carbon. Whether these carbon structures are conducting remains an open question.

First-principles calculations predict that a thin layer of VO2 sandwiched between TiO2 layers has electronic states that exhibit both linear and quadratic dispersion.

A critical thickness below which thin films of the metallic ferromagnet SrRuO3 become insulating and lose their ferromagnetic properties has been determined.

Coupling two electromechanical oscillators can extend the range over which each individual device is practically useful.

Collisions between nano-particles can sometimes result in more kinetic energy coming out than went in, new simulations show.
