Single-atom Bit Forms Smallest Memory In The World
2013-11-18 12:09:44

Karlsruhe Institute of Technology Control of the Magnetic Moment of Single Atoms Is the Key to Compact Data Memories and Quantum Computers One atom equals one bit: According to this design principle, we would like to construct magnetic data memories in the future. Presently, a compound of several million atoms is needed to stabilize a magnetic bit in a way that hard disk data are secure for several years. However, researchers from KIT have just made a big step towards a single-atom...

Wireless Data Transmission At 100 Gigabits Per Second
2013-10-14 10:19:53

Karlsruhe Institute of Technology Extension of cable-based telecommunication networks requires high investments in both conurbations and rural areas. Broadband data transmission via radio relay links might help to cross rivers, motorways or nature protection areas at strategic node points, and to make network extension economically feasible. In the current issue of the Nature Photonics magazine, researchers present a method for wireless data transmission at a world-record rate of 100...

Extragalactic Ankle And Galactic Knee
2013-06-03 17:42:35

Karlsruhe Institute of Technology It is obvious from the data of the KASCADE-Grande experiment at the Karlsruhe Institute of Technology (KIT) that the so-called “knee” of the cosmic rays, a bend in the energy spectrum at high energies, is located at different energies for light and heavy particles. As regards light particles, the scientists have now found that the energy spectrum flattens again beyond the knee and forms a type of “ankle”. This structure indicates...

X-ray Tomography On An Embryo Of A Living Frog
2013-05-16 14:51:20

Karlsruhe Institute of Technology Classical X-ray radiographs provide information about internal, absorptive structures of organisms such as bones. Alternatively, X-rays can also image soft tissues throughout early embryonic development of vertebrates. Related to this, a new X-ray method was presented recently in a Nature article published by a German-American-Russian research team led by KIT. For periods of about two hours, time-lapse sequences of cellular resolution were obtained of...

Invisibility Cloak For Thermal Flow Constructed By Researchers
2013-05-08 15:09:27

Karlsruhe Institute of Technology By means of special metamaterials, light and sound can be passed around objects. KIT researchers now succeeded in demonstrating that the same materials can also be used to specifically influence the propagation of heat. A structured plate of copper and silicon conducts heat around a central area without the edge being affected. The results are presented in the Physical Review Letters journal. “For the thermal invisibility cloak, both materials...

Emmy Noether Research Group Leader Wolfram Pernice Achieves Breakthrough at KIT in Building an Efficient Single-photon Detector Ultrafast, efficient, and reliable single-photon detectors are among the most sought-after components in photonics and quantum communication, which have not yet reached maturity for practical application. Physicist Dr. Wolfram Pernice of the Karlsruhe Institute of Technology (KIT), in cooperation with colleagues at Yale University, Boston University, and Moscow...

Big Uncertainties For The Global Water Budget
2012-06-13 16:31:13

Results of Latest Models for Regional Precipitation and Temperature Distribution Deviate Strongly / Number of Measurement Stations Worldwide Is Decreasing Dramatically No life without water. Catastrophes like droughts or strong rains reflect our dependence on the water cycle and climate system. Hence, it is important to understand details of the water cycle among the atmosphere, oceans, and land. A study in the Journal of Hydrometeorology now outlines significant differences of global...

New Superconducting Materials Improve the Efficiency and Reliability of Grids and Systems For the first time, a superconducting current limiter based on YBCO strip conductors has now been installed at a power plant. At the Boxberg power plant of Vattenfall, the current limiter protects the grid for own consumption that is designed for 12 000 volts and 800 amperes against damage due to short circuits and voltage peaks. The new technology co-developed by Karlsruhe Institute of Technology and...

Researchers Transfer Concept Of Optical Invisibility Cloak To Sound Waves
2011-12-20 09:08:49

Progress of metamaterials in nanotechnologies has made the invisibility cloak, a subject of mythology and science fiction, become reality: Light waves can be guided around an object to be hidden, in such a way that this object appears to be non-existent. This concept applied to electromagnetic light waves may also be transferred to other types of waves, such as sound waves. Researchers from Karlsruhe Institute of Technology (KIT) have now succeeded in demonstrating for the first time an...

Word of the Day
  • The navel or umbilicus.
  • In Greek archaeology: A central boss, as on a shield, a bowl, etc.
  • A sacred stone in the temple of Apollo at Delphi, believed by the Greeks to mark the 'navel' or exact center-point of the earth.
'Omphalos' comes from the ancient Greek.
