Spin-glass: the quantum physics behind the discovery that won Frisee the Nobel

  • One response
The Nobel Prize in Physics was awarded this year to Giorgio LaFerrisi for his scientific contribution in understanding complex systems alongside climate researchers. The prize committee decided to focus on the solution he proposed to the spin-glass problem on the grounds that this model is able to explain many phenomena outside the physics of materials. What is a spin-glass phase and what is Frizi's contribution to the theory?

Researching the origin of uranium ingots from Nazi Germany

Before Nazi Germany got hold of it, the Allies disrupted this plan and seized the uranium ingots that were at the heart of the plan. The fate of most of these ingots is unknown, but some of them ended up in the hands of the US and European countries. American chemists have developed a method to identify the mine from which the uranium came
Simulating the collision as it could have been if the detector was more accurate (in the top image), allows the computer to be taught to analyze the collision more accurately and efficiently (in the bottom image). The red lines indicate the trajectory of the particles after the collision

Does consciousness arise from quantum mechanics?

  • 20 תגובות
In 1990 Penrose and Moroff hypothesized that the source of consciousness is in the fractal structure of the microtubules. The movement of the particles on the fractal is apparently explained with the help of the laws of quantum mechanics but this has never been proven. Now evidence of similar systems in the laboratory strengthens the hypothesis that the fractal forces the particles moving on it to obey the laws of quantum mechanics, but is this the cause of consciousness?

A device that will make it possible to answer one of the central questions in physics that remain unanswered

  • One response
More than 70 years ago, scientists in the field of physics came up with an idea to use magnetic fields and an atomic property called spin in order to put a body in two places at the same time. Now, a research group from Ben-Gurion University of the Negev has succeeded in implementing the idea and has even proposed an advanced version of the device that will provide future answers to one of the central questions in physics: Is there a connection between quantum theory and gravitation?

Basic concepts in quantum physics: wave-particle duality

  • 16 תגובות
Every week we will delve deeper into a physical idea known in popular literature and bridge the gap between what is shown in the media and what science really states. This time we will start with wave-particle duality, an elusive concept that sometimes raises more questions than answers, but in truth has long ceased to worry scientists

Dramatic improvement in the resolutions of static and dynamic photography

  • One response
The technology developed by the researchers is based on the innovative SPI (Single-pixel imaging) concept - imaging using a single-pixel sensor. This concept, which enables photography without a camera, has extensive potential in diverse applications such as the development of components in autonomous vehicle alert systems and improving the ability of microscopes to see deep into biological tissues

A visual illustration of one of the collisions observed in the Atlas detector, and is an example of the type of processes we are looking for, and the signature they leave in our detectors. In this case a Higgs boson is created, together with another massive boson called Z (the carrier of the weak force). The blue cones and the yellow rectangles adjacent to them represent the pair of quarks into which the Higgs decayed, in this case they are of the magic type. The Z decays into two particles called muons, which can be identified by the red lines in the image. From the CERN website

For the first time, the Higgs boson was characterized by its decay into a pair of "magic" quarks

  • One response
Researchers from Tel Aviv University were able to describe for the first time a rare physical process that begins with the Higgs boson - the "divine particle" that was first observed about a decade ago - and eventually decays into a pair of rare elementary particles * New observations from the Sarn particle accelerator in Switzerland helped researchers understand the process more clearly

The Technion researchers sent laser bursts (pulses) to the edges of the model (the two-dimensional structure) that created the hybrid waves in the material. The researchers discovered that these waves travel at a speed almost 1,000 times slower than the speed of light in free air (and almost 1,000 times faster than the speed of sound in free air).
