A time-tested photon interferometry technique is used to study the statistics of photons emitted by current fluctuations in a quantum conductor.

Microwave illumination of a high-mobility two-dimensional electron gas reveals quantum magneto-oscillations in both absorption coefficient and dc resistance.

Highly doped graphene can become superconducting.

The band structure of iron-based superconductors gives rise to yet another scenario for the appearance of Dirac fermions.

The race for realizing Majorana fermions—elusive particles that act as their own antiparticles—heats up, but we still await ideal materials to work with.

Transport characteristics of graphene nanoribbons have implications for nanodevices.

LaAlO3/SrTiO3 interfaces grown by different methods all show a metal-insulator transition, but the observed interfacial electric field strength is not consistent with a widely studied model.

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?

Due to unusual spinlike properties, electrons in graphene—despite scattering—exhibit a small increase in their conductivity.

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

Defects—in the form of vortices in superconductors or “strings” in the fabric of the universe—can reveal the state of a system at the time it was cooled.

Photoelectron spectroscopy reveals how carbon atoms aggregate to form domelike graphene structures on iridium surfaces.

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.

By generalizing the idea of a moveable mirror, it may be possible to observe the dynamical Casimir effect.

Can quantum electronic devices offer an experimental system that mimics the behavior of black holes?

In integer quantum Hall systems, do theory and experiment agree for the wrong reasons?

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.

Can a patterned semiconducting heterostructure yield a better “graphene”?

By exploiting the concept of particle-hole duality, one can realize a point junction between integer and fractional quantum Hall phases, which constitutes a crucial building block towards possible applications of the quantum Hall effect.

The fractional quantum Hall effect, thought to be special to two dimensions, may also flourish in three, providing a possible explanation for anomalies observed in certain 3D materials in high magnetic fields.
