Scientists at the Lawrence Livermore National Laboratory have discovered a new melt curve of hydrogen, resulting in the possible existence of a novel superfluid – a brand new state of matter
As reported in the Oct. 7 edition of the journal Nature, the researchers present the results of ab initio calculations of the hydrogen melt curve at pressures up to 2 million atmospheres.
The measurement of the high-pressure phases of hydrogen has been the focus of numerous experiments
Tracking newly discovered asteroids and comets to identify their orbits is the work of a small number of observatories. Yet UK students, using the Faulkes Telescope North – a remotely operated research quality telescope dedicated for educational use – will now be swelling these ranks. The students have taken such accurate data of a number of asteroids that the telescope has been awarded an observatory code and can now submit official data to the international body that monitors asteroids and comets,
An asteroid 2.9 miles long and 1.5 miles wide zoomed past Earth Sept. 29 and came within 962,951 miles of the planet. While this might not seem like a near miss, technically it is relatively close – merely four times the distance between Earth and the moon.
But, it’s not likely that a large space rock like this one would actually hit Earth in our lifetime, says physics professor Perry Gerakines, Ph.D. “The odds that an asteroid of this magnitude would impact the Earth are in the millions t
A team of UK scientists has used, for the first time, an extremely short-pulse laser to accelerate high-energy electrons over an incredibly short distance. Current accelerators can be hundreds of metres long, this is just a millimetre long.
Earlier laser-driven accelerators were inefficient, accelerating the electrons to a wide range of energies. But scientists who wish to use these electron beams to research materials science – such as the structure of viruses and moon rock – nee
Scientists from the UK and the USA have successfully demonstrated a new technique that could help to shrink the size and cost of future particle accelerators for fundamental physics experiments and applications in materials and biomedicine.
Using the huge electric fields in laser-produced plasmas, they have accelerated beams of electrons close to the speed of light, in an important step towards the development of a working laser electron accelerator that could sit on a table top.
The electrons of a perfect metallic surface move like free waves in a plane. Nevertheless, if atomic barriers are inserted, this may restrict their movement in one dimension, forming stationary waves such as those on the water surface in a bucket.
The stationary or free behaviour of electron waves is, nevertheless, still something very intriguing, given that the barriers of atoms are very close to each other, there is no confinement, and that the electron recovers its free movement
