A recent study demonstrates the rapid control of phase-changes in resonantly bonded materials
Rewritable CDs, DVDs and Blu-Ray discs owe their existence to phase-change materials, those materials that change their internal order when heated and whose structures can be switched back and forth between their crystalline and amorphous phases. Phase-change materials have even more exciting ...
In a recent study published in Physical Review Letters and highlighted by the magazine Science News, the research group led by ICREA Prof at ICFO Morgan Mitchell has detected, for the first time, entanglement among individual photon pairs in a beam of squeezed light.Quantum entanglement is always ...
Graphene combined with the insulting power of boron nitride enables light control in tiny circuits with dramatically reduced energy loss
Squeezing light into tiny circuits and controlling its flow electrically is a holy grail that has become a realistic scenario thanks to the discovery of graphene. This tantalizing achievement is realized by exploiting so-called plasmons, in which electrons and light move together as one coherent ...
Researchers at ICFO have invented nano-optical tweezers capable of trapping and moving an individual nano-object in 3 dimensions using only the force of light
As science and technology go nano, scientists search for new tools to manipulate, observe and modify the "building blocks" of matter at the nanometer scale. With this in mind, the recent publication in Nature Nanotechnology in which ICFO researchers demonstrate for the first time the ability to ...
In a recent study published in Science researchers have been able to observed, for the first time, the collective spin dynamics of ultra-cold fermions with large spins
Understanding collective behavior of ultra-cold quantum gases is of great interest since it is intimately related to many encountered systems in nature such as human behavior, swarms of birds, traffic jam, sand dunes, neutron stars, fundamental magnetic properties of solids, or even ...
High power conversion of new solar cells that are thin, flexible, and transparent makes them ideal for a wealth of new applications
Imagine buildings in which the windows allow the sun's light to enter, and at the same time capture the energy from the sun needed to meet all their energy needs. In this seemingly futuristic scenario, the windows become productive solar cells that help us decrease our reliance on fossil fuels ...
ICFO scientists have shown that a nano-size diamond at room temperature can act as an efficient optical switch controllable with light
A recent study led by researchers of the ICFO (Institute of Photonic Sciences) demonstrates that a single nano-diamond can be operated as an ultrafast single-emitter optical switch operating at room temperature. Electronic transistors have become a key component to modern electronics, drastically ...
ICFO scientists show that graphene is highly efficient in converting light to electricity
Bottles, packaging, furniture, car parts... all made of plastic. Today we find it difficult to imagine our lives without this key material that revolutionized technology over the last century. There is wide-spread optimism in the scientific community that graphene will provide similar paradigm ...
