Nanotube-based terahertz polarizer nears perfection

(PhysOrg.com) -- Researchers at Rice University are using carbon nanotubes as the critical component of a robust terahertz polarizer that could accelerate the development of new security and communication devices, sensors ...

Nano antenna concentrates light: Intensity increases 1,000-fold

(PhysOrg.com) -- Everybody who's ever used a TV, radio or cell phone knows what an antenna does: It captures the aerial signals that make those devices practical. A lab at Rice University has built an antenna that captures ...

Counting the 'Holes' in High-Temperature Superconductors

(PhysOrg.com) -- As part of the effort to better understand how superconductors transport electricity with zero resistance, a team of researchers has demonstrated a new way to count the number of a material's "holes" - locations ...

Creating a quantum gas

(PhysOrg.com) -- "One of the many reasons people study ultracold gases is for their potential as model quantum systems," Deborah Jin tells PhysOrg.com. "There is a need to model quantum many-body systems because a lot of ...

Quantum materials: A new state of matter with chiral properties

An international research group has discovered a new state of matter characterized by the existence of a quantum phenomenon called chiral current. These currents are generated on an atomic scale by a cooperative movement ...
