Higgs Mode in Superconductors

Posted by in categories: computing, particle physics, quantum physics

This could usher in higgs exotic physics computing that is beyond even quantum computers.


When a continuous symmetry of a physical system is spontaneously broken, two types of collective modes typically emerge: the amplitude and phase modes of the order-parameter fluctuation. For superconductors, the amplitude mode is recently referred to as the ‘’Higgs mode’’ as it is a condensed-matter analogue of a Higgs boson in particle physics. Higgs mode is a scalar excitation of the order parameter, distinct from charge or spin fluctuations, and thus does not couple to electromagnetic fields linearly. This is why the Higgs mode in superconductors has evaded experimental observations over a half century after the initial theoretical prediction, except for a charge-density-wave coexisting system.

Heat energy leaps through empty space, thanks to quantum weirdness

Posted by in categories: particle physics, quantum physics

If you use a vacuum-insulated thermos to help keep your coffee hot, you may know it’s a good insulator because heat energy has a hard time moving through empty space. Vibrations of atoms or molecules, which carry thermal energy, simply can’t travel if there are no atoms or molecules around.

But a new study by researchers at the University of California, Berkeley, shows how the weirdness of quantum mechanics can turn even this basic tenet of classical physics on its head.

The study, appearing this week in the journal Nature, shows that can leap across a few hundred nanometers of a complete vacuum, thanks to a quantum mechanical phenomenon called the Casimir interaction.

Recordings reveal that plants make ultrasonic squeals when stressed

Posted by in categories: biological, quantum physics

Plants do have sentience they just need less to survive. Just look at the sci fi character groot. They may not seem like they are sentient but they show it in different ways because they are plants, not humans. Essentially they even give off radiation aswell their biology is so advanced that even today there are still mysteries unsolved. Many energy-sensitive people can feel their energy they emit and can intuitively know their needs. Even native Americans have even learned that they are superorganisms on earth and have found ways to bring their rain through a series of metaphysical triggers. The native Americans advanced wetware and spirit binds to the plants then allows for even a psychic link talking to the plant even on their level. The earth itself is said to be a superorganism. A lot of times on plant can be a psychic link between their vast universe of understanding but it takes plant intuitive people. Many legends have risen from plants being sentient even in modern-day. In my opinion, plants are just as complex as human beings because they require less energy to function. There is a comic in the series poison ivy that even made plant children in humanoid beings. I think this is a definite possibility just it is advanced wetware. But as we learn more about the quantum mechanical realm we will discover that plants may be more advanced than even our own biology. That why often we need to respect nature because it is actually sentient and we evolve with it. Someday we really could be tree people just it would take a long time to eventually make real. But it is a very real possibility.


For the first time plants have been recorded making sounds when stressed. The sounds differed when they were injured or thirsty, a finding that could help farmers.

The new particle tested as a possible Higgs boson[edit]

Posted by in categories: particle physics, quantum physics

The Higgs boson is an elementary particle in the Standard Model of particle physics, produced by the quantum excitation of the Higgs field,[8][9] one of the fields in particle physics theory.[9] It is named after physicist Peter Higgs, who in 1964, along with five other scientists, proposed the Higgs mechanism to explain why particles have mass. This mechanism implies the existence of the Higgs boson. The boson’s existence was confirmed in 2012 by the ATLAS and CMS collaborations based on collisions in the LHC at CERN.

On December 10, 2013, two of the physicists, Peter Higgs and François Englert, were awarded the Nobel Prize in Physics for their theoretical predictions. Although Higgs’s name has come to be associated with this theory (the Higgs mechanism), several researchers between about 1960 and 1972 independently developed different parts of it.

In mainstream media the Higgs boson has often been called the “God particle”, from a 1993 book on the topic,[10] although the nickname is strongly disliked by many physicists, including Higgs himself, who regard it as sensationalism.[11][12].

New laser technique images quantum world in a trillionth of a second

Posted by in categories: biotech/medical, quantum physics

For the first time, researchers have been able to record, frame-by-frame, how an electron interacts with certain atomic vibrations in a solid. The technique captures a process that commonly causes electrical resistance in materials while, in others, can cause the exact opposite—the absence of resistance, or superconductivity.

“The way electrons interact with each other and their microscopic environment determines the properties of all solids,” said MengXing Na, a University of British Columbia (UBC) Ph.D. student and co-lead author of the study, published last week in Science. “Once we identify the dominant microscopic interactions that define a material’s properties, we can find ways to ‘turn up’ or ‘down’ the interaction to elicit useful electronic properties.”

Controlling these interactions is important for the technological exploitation of quantum materials, including superconductors, which are used in MRI machines, high-speed magnetic levitation trains, and could one day revolutionize how energy is transported.

Quantum field theory: “An unholy crossbreed between quantum physics in a bad mood and every button you never push on a calculator”

Posted by in categories: particle physics, quantum physics

Quantum field theory doesn’t get much coverage in popular science and if you open any textbook on the subject you’ll see why. It looks like an unholy crossbreed between quantum physics in a bad mood and every button you never push on a calculator. The idea of summarising it in 1,500 words or less for this article sounded daunting at first (it took a whole chapter to cover it in my recent book) but then again if I really did have to present it to a jury of aliens I wouldn’t have a choice.

Therefore, your honour, I request that you give me five minutes of your intergalactic attention. My presentation may not feature Jason Statham roundhouse kicking a shark in the eyeball, but I am going to try and justify the continued existence of the human race. Here goes…

In surprise breakthrough, scientists create quantum states in everyday electronics

Posted by in categories: computing, engineering, mobile phones, particle physics, quantum physics, transportation

After decades of miniaturization, the electronic components we’ve relied on for computers and modern technologies are now starting to reach fundamental limits. Faced with this challenge, engineers and scientists around the world are turning toward a radically new paradigm: quantum information technologies.

Quantum technology, which harnesses the strange rules that govern particles at the , is normally thought of as much too delicate to coexist with the electronics we use every day in phones, laptops and cars. However, scientists with the University of Chicago’s Pritzker School of Molecular Engineering announced a significant breakthrough: Quantum states can be integrated and controlled in commonly used made from silicon carbide.

“The ability to create and control high-performance quantum bits in commercial electronics was a surprise,” said lead investigator David Awschalom, the Liew Family Professor in Molecular Engineering at UChicago and a pioneer in quantum technology. “These discoveries have changed the way we think about developing quantum technologies—perhaps we can find a way to use today’s electronics to build quantum devices.”

Liquid flow is influenced by a quantum effect in water

Posted by in categories: biotech/medical, quantum physics

Researchers at EPFL have discovered that the viscosity of solutions of electrically charged polymers dissolved in water is influenced by a quantum effect. This tiny quantum effect influences the way water molecules interact with one another. Yet, it can lead to drastic changes in large-scale observations. This effect could change the way scientists understand the properties and behavior of solutions of biomolecules in water, and lead to a better understanding of biological systems.

Water is the basis of all life on earth. Its structure is simple—two bound to one —yet its behavior is unique among liquids, and scientists still do not fully understand the origins of its distinctive properties.

When charged polymers are dissolved in water the aqueous becomes more viscous than expected. This high viscosity is used by nature in the human body. The lubricating and shock-absorbing properties of the synovial fluid—a solution of water and charged biopolymers—is what allows us to bend, stretch and compress our joints over our entire lives without damage.
