Graphene drum: A new phonon laser design

Professor Konstantin Arutyunov of the HSE Tikhonov Moscow Institute of Electronics and Mathematics (MIEM HSE), together with Chinese researchers, has developed a graphene-based mechanical resonator, in which coherent emission ...

Light-controlled reactions at the nanoscale

Controlling strong electromagnetic fields on nanoparticles is the key to triggering targeted molecular reactions on their surfaces. Such control over strong fields is achieved via laser light. Although laser-induced formation ...

Lens trick doubles odds for quantum interaction

It's not easy to bounce a single particle of light off a single atom that is less than a billionth of a metre wide. However, researchers at the Centre for Quantum Technologies at the National University of Singapore have ...

Light tsunami in a superconductor

Superconductors are materials which conduct electric currents without any resistance. At the Helmholtz-Zentrum Dresden-Rossendorf, an international research team headed by Professor Andrea Cavalleri from the Max Planck Institute ...

Researchers develop new method for detecting superfluid motion

Researchers at Rochester Institute of Technology are part of a new study that could help unlock the potential of superfluids—essentially frictionless special substances capable of unstopped motion once initiated. A team ...

Laser beams with a 'twist'

(University of the Witwatersrand) Using geometric phase inside lasers for the first time, researchers find a way to change the orbital angular momentum of laser beams.

Optical tweezer technology tweaked to overcome dangers of heat

Three years ago, Arthur Ashkin won the Nobel Prize for inventing optical tweezers, which use light in the form of a high-powered laser beam to capture and manipulate particles. Despite being created decades ago, optical tweezers ...

Manipulating Lorentz and Fano spectral line shapes

(Phys.org) —It is widely known that the optical properties of certain materials can be modified by using lasers to control the quantum states of their optical electrons. Lasers that can generate ultra-short pulses in the ...
