Experiments show signs of a material that conducts electricity in opposite directions along its edges through fractionally charged quasiparticles.

A new theory examines the various ways quasiparticles pair up in two-dimensional semiconductors under high magnetic fields.

Removing a mirror while a single photon is in the process of reflecting creates a quantum state of countless photons, theorists say.

A mineral physics interpretation of NASA seismic data hints that Mars has a chemically evolved crust.

A framework based on knot theory links the robustness of textiles to the way defects propagate through them.
