“I wanted to find answers to fundamental questions, and I wanted to know what holds the world together. Minimal electrical voltage is used to slip a single atom between a silver and a platinum pad, causing a digital signal to be emitted. To begin its work, the Centre of Atomic Scale Technologies is using initial Foundation funding to create 14 positions for PhD candidates and postdocs, and to purchase additional equipment to analyse and optimise nano-components. Hubble’s discovery was the first observational support for Georges Lemaître’s Big Bang theory of the universe, proposed in 1927. Lemaître proposed that the universe expanded explosively from an extremely dense and hot state, and continues to expand today. Subsequent calculations have dated this Big Bang to approximately 13.7 billion years ago.

Atoms Cooling With Laser

The detection of this particle is difficult because it decays quickly. Pions decay so quickly that most of the particles have transformed in other particles by the time they reach the surface of the Earth. We are interested in controlling and measuring single electron charge transfer between molecules and ultimately within molecule–metal networks on surfaces. Recently we measured the reorganization energy upon charging a single molecule on an insulator. By showing entanglement between light and vibration in a crystal that one could hold in their finger during the experiment, the new study creates a bridge between our daily experience and the fascinating realm of quantum mechanics. The researchers used a very short laser-pulse to trigger a specific pattern of vibration inside a diamond crystal.

  • “We first used silver, because it was the easiest way to realise the single-atom transistor,” Schimmel explains.
  • This new experiment requires a lower density target to

Now researchers at ETH have found a way to apply this measurement principle to individual atoms. One can attach and detach single electron charges to molecules and atoms using the microscope tip . Using Kelvin probe force microscopy, we detect atomic charge states and molecular charge distributions . Imaging the structure of molecules with atomic resolution was achieved by noncontact atomic force microscopy (NC-AFM).

This workshop follows the submission of a community letter, which outlined the intention to organise a community workshop is to discuss options for a quantum technology development programme coordinated at the Europe-wide level. An even more mysterious form of energy called “dark energy” accounts for about 70% of the mass-energy content of the universe. This idea stems from the observation that all galaxies seems to be receding from each other at an accelerating pace, implying that some invisible extra energy is at work. Phillips, “Laser cooling … Read More

Green Light On Gold Atoms

Green Light On Gold Atoms

Our research combines experiment with theory, employing techniques of atomic physics, quantum optics and optomechanics. A common goal of our activities is to investigate quantum physics in systems of increasing size and complexity. In the laboratories of modern physics the elementary components of matter are studied. To do this, scientists sometimes build artificial atoms to help them understand the laws of matter. A research team at the Paul Scherrer Institute (Villigen/AG) uses a specifically modified helium atom to determine the exact mass and other properties of pions. Pions could help to understand more precisely where atomic nuclei get their mass from.
