100 amps of electricity crackle in a vacuum chamber, creating a spark that transforms carbon vapor into tiny structures. Depending on the conditions, these structures can be shaped like little, 60-atom soccer balls, or like rolled-up tubes of atoms, arranged in a chicken-wire pattern, with rounded ends. These tiny, carbon nanotubes, discovered by Sumio Iijima at NEC labs in 1991, have amazing properties. They are 100 times stronger than steel, but weigh only one-sixth as much. They are incredibly resilient under physical stress; even when kinked to a 120-degree angle, they will bounce back to their original form, undamaged. And they can carry electrical current at levels that would vaporize ordinary copper wires.

IWCN 2021: A Practical Peierls Phase Recipe for Periodic Atomistic Systems Under Magnetic Fields
14 Jul 2021 | | Contributor(s):: Alessandro Cresti
In this contribution I will provide general ready-to-use formulas to determine Peierls phase factors that preserve the translation symmetry of any periodic quasi-one-dimensional or two-dimensional system under a homogeneous magnetic field.
Carbon Nanotube Fracture
27 May 2021 | | Contributor(s):: Christine M Aikens, George C. Schatz, Marcelo Carignano
Due to their mechanical properties, carbon nanotubes (CNTs) hold promise as nanoreinforcements in a variety of composites. As a result, numerous theoretical and experimental studies have been performed in order to understand the behavior of CNTs under axial tension. Whereas quantum mechanical...

Covalent Defects of Carbon Nanotubes: New Class of High Purity, Indistinguishable Quantum Light Sources
02 Jan 2020 | | Contributor(s):: Han Htoon
Finally, I will report our most recent Hong-Ou-Mandel quantum optic experiment performed on quantum defects coupled to plasmonic cavities. We were able to realize indistinguishable single photon generation by exploiting the Purcell enhancement of the radiative decay rate of individual...
