Laser-Driven Implosion

Authors: George Rajna
Comments: 24 Pages.

Scientists at Osaka University discovered a novel particle acceleration mechanism they describe as a micro-bubble implosion, in which super-high energy hydrogen ions (relativistic protons) are emitted at the moment when bubbles shrink to atomic size through the irradiation of hydrides with micron-sized spherical bubbles by ultraintense laser pulses [13] Conventional electron accelerators have become an indispensable tool in modern research. [12] An outstanding conundrum on what happens to the laser energy after beams are fired into plasma has been solved in newly-published research at the University of Strathclyde. [11] Researchers at Lund University and Louisiana State University have developed a tool that makes it possible to control extreme UV light-light with much shorter wavelengths than visible light. [10] Tiny micro-and nanoscale structures within a material's surface are invisible to the naked eye, but play a big role in determining a material's physical, chemical, and biomedical properties. [9] A team of researchers led by Leo Kouwenhoven at TU Delft has demonstrated an on-chip microwave laser based on a fundamental property of superconductivity, the ac Josephson effect. They embedded a small section of an interrupted superconductor, a Josephson junction, in a carefully engineered on-chip cavity. Such a device opens the door to many applications in which microwave radiation with minimal dissipation is key, for example in controlling qubits in a scalable quantum computer. [8]

Universal Pattern Leading to Proton Radius Puzzle Solved

Authors: J. Gielen
Comments: 14 Pages.

A unique pattern found in stockmarket graphs is found in all other graphs too. For instance at earthquake graphs, maybe able to predict earlier a break-out. Also leading to the proton, it's movement and even the solvent of the proton radius puzzle! Alpha, pi and proton get connected!

Outlines of Rutherford’s α-Particles Scattering Experiment

Authors: Arjun Dahal, Nikita Parajuli
Comments: 6 Pages. ©2017-2018 Journal of St. Xavier's Physics Council

Rutherford’s α-particles scattering experiment was one of the milestone for the physics community as it provided an insight to an atom thus discarding the previously prevailed Thomson’s model. Through this article we shall examine the theoretical formulation of Rutherford’s experiment and how it helped to shape the modern physics.

Photons and the Diverse Nature of Light

Authors: David Johnson
Comments: 4 Pages.

Electromagnetic radiation (EMR) can be produced by a range of large-scale events (nuclear reactions, galaxy collisions, the Big Bang etc.) or by smaller scale events such as the excitement of a gas or a chemical reaction. This short article focuses on the nature of photons and their transmission as ‘normal’ light, plane and circularly polarised light and transverse mode light.

Material-Aging Process

Authors: George Rajna
Comments: 55 Pages.

According to the researchers, aging originates at the atomic and molecular levels. [21] The most surprising result from beta decay is that nature is not ambidextrous, but is "left-handed." [20] This week, a group of scientists working on the MiniBooNE experiment at the Department of Energy's Fermilab reported a breakthrough: They were able to identify exactly-known-energy muon neutrinos hitting the atoms at the heart of their particle detector. [19] In a study published in Physical Review Letters, collaborators of the MAJORANA DEMONSTRATOR, an experiment led by the Department of Energy's Oak Ridge National Laboratory, have shown they can shield a sensitive, scalable 44-kilogram germanium detector array from background radioactivity. [18] The study has put the most stringent limits on the probability of a rare event—a neutrinoless double beta decay of tellurium-130 nuclei. This event can only occur if a neutrino can be its own antiparticle. [17] While these experiments seem miniature in comparison to others, they could reveal answers about neutrinos that have been hiding from physicists for decades. [16] In a paper published today in the European Physical Journal C, the ATLAS Collaboration reports the first high-precision measurement at the Large Hadron Collider (LHC) of the mass of the W boson. [15] A team of researchers at the University of Michigan has conducted a thought experiment regarding the nature of a universe that could support life without the weak force. [14] The international T2K Collaboration announces a first indication that the dominance of matter over antimatter may originate from the fact that neutrinos and antineutrinos behave differently during those oscillations. [13] Neutrinos are a challenge to study because their interactions with matter are so rare. Particularly elusive has been what's known as coherent elastic neutrino-nucleus scattering, which occurs when a neutrino bumps off the nucleus of an atom. [12] Lately, neutrinos – the tiny, nearly massless particles that many scientists study to better understand the fundamental workings of the universe – have been posing a problem for physicists. [11]

Magic Numbers of Nuclei

Authors: George Rajna
Comments: 36 Pages.

The identification of the magic number of six provides an avenue to investigate the origin of spin–orbit splittings in atomic nuclei. [25] Now, physicists are working toward getting their first CT scans of the inner workings of the nucleus. [24] The process of the sticking together of quarks, called hadronisation, is still poorly understood. [23] In experimental campaigns using the OMEGA EP laser at (MIT) researchers took radiographs of the shock front, similar to the X-ray radiology in hospitals with protons instead of X-rays. [22] Researchers generate proton beams using a combination of nanoparticles and laser light. [21] Devices based on light, rather than electrons, could revolutionize the speed and security of our future computers. However, one of the major challenges in today's physics is the design of photonic devices, able to transport and switch light through circuits in a stable way. [20] Researchers characterize the rotational jiggling of an optically levitated nanoparticle, showing how this motion could be cooled to its quantum ground state. [19] Researchers have created quantum states of light whose noise level has been " squeezed " to a record low. [18] An elliptical light beam in a nonlinear optical medium pumped by " twisted light " can rotate like an electron around a magnetic field. [17] Physicists from Trinity College Dublin's School of Physics and the CRANN Institute, Trinity College, have discovered a new form of light, which will impact our understanding of the fundamental nature of light. [16] Light from an optical fiber illuminates the metasurface, is scattered in four different directions, and the intensities are measured by the four detectors. From this measurement the state of polarization of light is detected. [15]

The Golden Section in Physics (in English)

Authors: Dezso Sarkadi
Comments: 4 Pages.

The physical constants play important role in physics. It is fact that the accuracy of the physical constants grows year by year. Special attention is paying to the dimensionless constants; the most familiars among them are the fine structure constant, the electron/proton and electron/muon mass-ratios, the ratio of the gravitational/electromagnetic interaction, the Weinberg angle in the electro-weak interaction theory, etc. The one of the most important questions is for a long time: are there any physical and/or mathematical relations between the fundamental physical constants. The paper gives a recently explored simple math relation between them. The precise theoretical explanation of this amazing finding need more detailed investigations related to the physical background. Keywords: exponential relations between physical constants, Titius-Bode rule, new atomic mass formula.
