Physicists at the University of Basel have shown for the first time how a single electron looks in an artificial atom. A newly developed method enables them to show the probability of an electron being present in a space. This allows improved control of electron spins, which could serve as the smallest information unit in a future quantum computer. The experiments were published in Physical Review Letters and the related theory in Physical Review B.

The results of a Russian-Japanese experiment explain the mechanism of electron photoemission by metallic nanostructures under ultrafast laser excitation. Metallic nanoparticle ensembles are capable of emitting short bunches of electrons when irradiated by powerful laser pulses of femtosecond (1 fs = 10-15 s) duration. Scientists at Lobachevsky University have long studied the plasmon effect—the excitation by light of collective electron oscillations in nanoparticles and the amplification of the light field associated with these oscillations in the vicinity of the nanoparticle, which plays the main role in this process. It is the plasmon amplification of the field that provides effective photoemission of electrons from a metal.

Author(s): K. Sekizawa and K. Hagino Creating new elements becomes increasingly difficult because the colliding nuclei must be sufficiently neutron-rich and heavy, and live long enough to be suitable as a target or beam. The authors develop a new hybrid model that combines two proven reaction techniques, time-dependent-Hartree-Fock and diffusion over a fusion barrier using the Langevin approach. By comparing different pairs of collision partners to form superheavy nuclei with Z=120, an initial, simplified version of the model already sheds some light on the way to synthesize the heaviest elements.

In conventional holography a photographic film can record the interference pattern of monochromatic light scattered from the object to be imaged with a reference beam of un-scattered light.

Holography was originally proposed by the physicist Dennis Gabor in 1948 to improve the resolution of an electron microscope, demonstrated using light optics. A hologram can be formed by capturing the phase and amplitude distribution of a signal by superimposing it with a known reference. The original concept was followed by holography with electrons, and after the invention of lasers optical holography became a popular technique for 3-D imaging macroscopic objects, information encryption and microscopy imaging.

Nanozymes are catalytic nanomaterials with enzyme-like characteristics that have attracted enormous recent research interest. The catalytic nanomaterials offer unique advantages of low cost, high stability, tunable catalytic activity and ease of mass production and storage. These properties are highly desirable for a wide range of applications in biosensing, tissue engineering therapeutics and environmental protection. However, conventional nanozyme technologies face critical challenges relative to their size, composition and facet-dependent catalysis, in addition to inherently low active site density.

15:45 Phys.orgPhysicists discover new type of spin waves

Current technologies for information transfer and processing are challenged by fundamental physical limits. The more powerful they become, the more energy they need, and the more heat is released to the environment. Also, there are physical limits on the smallness and efficiency of communication devices. The recent discovery by physicists at Martin Luther University Halle-Wittenberg (MLU) and Lanzhou University in China offers a new route for progress on these issues. In the latest edition of the scientific journal Nature Communications, they describe a novel type of spin wave that can be used to transmit and process information with considerably higher efficiency and lower energy consumption.
