Novel approach to coherent control of a three-level quantum system
Novel approach to coherent control of a three-level quantum system
For the first time, researchers were able to study quantum interference in a three-level quantum system and thereby control the behavior of individual electron spins. To this end, they used a novel nanostructure, in which a quantum system is integrated into a nanoscale mechanical oscillator in form of a diamond cantilever.

EPFL uses excitons to take electronics into the future
EPFL uses excitons to take electronics into the future
EPFL researchers have developed a transistor based on excitons - a type of particle most people have not heard of - that is able to function at room temperature. This breakthrough could lead to a new breed of faster, more energy efficient and smaller electronics. Excitons could revolutionize the way engineers approach electronics.

Material from PSI helps to check inconsistencies in the Big Bang theory
Material from PSI helps to check inconsistencies in the Big Bang theory
Shortly after the Big Bang, radioactive atoms of the type beryllium-7, among others, came into being. Today, throughout the universe, they have long since decayed and do not occur naturally, in contrast to their decay product lithium. Now researchers at the Paul Scherrer Institute PSI have helped to better understand the first minutes of the universe: They collected artificially produced beryllium-7 and made it into a sample that could be investigated.

Electrical contact to molecules in semiconductor structures established for the first time
Electrical contact to molecules in semiconductor structures established for the first time
Electrical circuits are constantly being scaled down and extended with specific functions. A new method now allows electrical contact to be established with simple molecules on a conventional silicon chip. The technique promises to bring advances in sensor technology and medicine, as reported by chemists from the University of Basel and researchers from IBM Research - Zurich in Rüschlikon.

On the path to new high-performance transistors
X-rays aid better understanding of electron mobility in a modern transistor The electronics industry expects a novel high-performance transistor made of gallium nitride to offer considerable advantages over present-day high-frequency transistors. Yet many fundamental properties of the material remain unknown.

A step closer to single-atom data storage
A step closer to single-atom data storage
Physicists at EPFL used Scanning Tunneling Microscopy to successfully test the stability of a magnet made up of a single atom. Despite the rise of solid-state drives, magnetic storage devices such as conventional hard drives and magnetic tapes are still very common. But as our data-storage needs are increasing at a rate of almost 15 million gigabytes per day, scientists are turning to alternative storage devices.

Making opaque materials totally transparent
Making opaque materials totally transparent
EPFL researchers have found a way to make materials that are normally opaque to sound waves completely transparent. Their system involves placing acoustic relays at strategic locations so that sound waves can propagate at a constant amplitude - regardless of what may lie in their path. This method could eventually be used to make it possible to hide objects like submarines.

Tracking down the smallest particles
Tracking down the smallest particles
Nanomaterials consist of tiny particles of different composition. They are used, for example, in textiles and can enter aquatic systems directly from the factory, while being worn or disposed of. For years, research groups at Eawag have been investigating the effects of artificially manufactured nanoparticles on human beings and the environment.

Diamond watch components
Diamond watch components
Researchers have developed a new technique for carving materials to create micromechanical systems. In particular, they have created a miniscule watch component out of synthetic single-crystal diamond. Diamond is very hard and elastic, a very good thermal conductor and highly transparent, which makes it ideal for many mechanical and optical applications.

Biological light sensor filmed in action
Film shows one of the fastest processes in biology Using X-ray laser technology, a team led by researchers of the Paul Scherrer Institute PSI has recorded one of the fastest processes in biology. In doing so, they produced a molecular movie that reveals how the light sensor retinal is activated in a protein molecule.

Tracking down the mystery of entangled particles of light
Tracking down the mystery of entangled particles of light
Bernese researchers have taken an important step towards new measurement methods such as quantum spectroscopy. In an experiment, they succeeded in uncovering part of the mystery surrounding the so-called "entangled photons" and gaining fine control on the measured correlations. Quantum technologies hold the promise to go beyond the capabilities of classical present technologies by making use of pure quantum phenomenon, such as "entangled particles".

A nanotech sensor turns molecular fingerprints into bar codes
A new system developed at EPFL can detect and analyze molecules with very high precision and without needing bulky equipment. It opens the door to large-scale, image-based detection of materials aided by artificial intelligence. Infrared spectroscopy is the benchmark method for detecting and analyzing organic compounds.

Direct Coupling of the Higgs Boson to the Top Quark Observed
Direct Coupling of the Higgs Boson to the Top Quark Observed
On 4 July 2012, two of the experiments at the CERN's Large Hadron Collider (LHC), ATLAS (A Toroidal LHC ApparatuS) and CMS (Compact Muon Solenoid), reported independently the discovery of the Higgs boson. The discovery confirmed the existence of the last missing elementary particle of the Standard Model, half a century after the Higgs boson was predicted theoretically.

Hollywood in the Würenlingen woods
With the X-ray laser SwissFEL, researchers at PSI want to produce movies of biomolecules in action. This can reveal how our eyes function or how new drugs work. Luc Patthey stands next to a complicated arrangement of optical lenses, measuring instruments, countless cables, and a thin steel pipe. We're in Hollywood here.

Deciphering the language of cells using observation chambers
EPFL researchers have developed an innovative label-free method for studying the behavior of single cells continuously and in real time. By placing a cell in a small chamber containing nanosensors and observing it over many hours, it is possible to identify the cell's unique personality and understand how it communicates.

Observing cellular activity, one molecule at a time
Using a new mode of atomic force microscopy, researchers at EPFL have found a way to see and measure protein assembly in real time and with unprecedented detail. Proteins and molecules assemble and disassemble naturally as part of many essential biological processes. It is very difficult to observe these mechanisms, which are often complex and take place at the nanometer scale, far smaller than the normal visible range.
