Graviton laser

Posted by in category: quantum physics

A gravity laser :DDD.


We consider the possibility of creating a graviton laser. The lasing medium would be a system of contained, ultra cold neutrons. Ultra cold neutrons are a quantum mechanical system that interacts with gravitational fields and with the phonons of the container walls. It is possible to create a population inversion by pumping the system using the phonons. We compute the rate of spontaneous emission of gravitons and the rate of the subsequent stimulated emission of gravitons. The gain obtainable is directly proportional to the density of the lasing medium and the fraction of the population inversion. The applications of a graviton laser would be interesting.

Higgs Boson Creation in Laser-Boosted Lepton Collisions

Posted by in categories: particle physics, quantum physics

Higgs boson laser.


Electroweak processes in high-energy lepton collisions are considered in a situation where the incident center-of-mass energy lies below the reaction threshold, but is boosted to the required level by subsequent laser acceleration. Within the framework of laser-dressed quantum field theory, we study the laser-boosted process $\ell^+ \ell^- \to HZ^0$ in detail and specify the technical demands needed for its experimental realization. Further, we outline possible qualitative differences to field-free processes regarding the detection of the produced Higgs bosons.

New form of matter discovered that has only ever been seen in sci-fi

Posted by in categories: particle physics, weapons

Scientists have accidentally discovered a completely new form of matter that works in the same way as the lightsabers used in Star Wars.

A team of physicists were messing around with photons when they managed to get the particles to stick together and form a molecule.

The molecule behaves, they claim, just like a lightsaber by moving the light particles around in a solid mass and is unlike any matter seen before.

Newsom: More than half of California projected to contract COVID-19

Posted by in category: biotech/medical

More than half of Californians are projected to contract the novel coronavirus, Gov. Gavin Newsom said in a letter to President Donald Trump asking for more resources.

“We project that roughly 56 percent of our population — 25.5 million people — will be infected with the virus over an eight-week period,” Newsom said in the letter.

The U.S. wants smartphone location data to fight coronavirus. Privacy advocates are worried

Posted by in categories: biotech/medical, government, health, mobile phones, surveillance

The White House and the Centers for Disease Control and Prevention are asking Facebook, Google and other tech giants to give them greater access to Americans’ smartphone location data in order to help them combat the spread of the coronavirus, according to four people at companies involved in the discussions who are not authorized to speak about them publicly.

Federal health officials say they could use anonymous, aggregated user data collected by the tech companies to map the spread of the virus — a practice known as “syndromic surveillance” — and prevent further infections. They could also use the data to see whether people were practicing “social distancing.”

Some sources stressed that the effort would be anonymized and that government would not have access to specific individuals’ locations. They noted that users would be required to opt-in to the effort.

$20 trillion lawsuit against China! US group says coronavirus is bioweapon

Posted by in categories: biotech/medical, terrorism

The plaintiffs have sought $20 trillion, which is a bigger amount than China’s GDP, claiming coronavirus is the result of a biological weapon prepared by the Chinese authorities.

They have accused China of aiding and abetting death, provision of material support to terrorists, conspiracy to cause injury and death of US citizens, negligence, wrongful death, and assault and battery.

Visibility of the amplitude (Higgs) mode in condensed matter

Posted by in categories: energy, quantum physics

The amplitude mode is a ubiquitous collective excitation in condensed-matter systems with broken continuous symmetry. It is expected in antiferromagnets, short coherence length superconductors, charge density waves, and lattice Bose condensates. Its detection is a valuable test of the corresponding field theory, and its mass gap measures the proximity to a quantum critical point. However, since the amplitude mode can decay into low-energy Goldstone modes, its experimental visibility has been questioned. Here we show that the visibility depends on the symmetry of the measured susceptibility. The longitudinal susceptibility diverges at low frequency as Im χ σ σ ∼ ω − 1 (d = 2) or log (1 / | ω |) (d = 3), which can completely obscure the amplitude peak. In contrast, the scalar susceptibility is suppressed by four extra powers of frequency, exposing the amplitude peak throughout the ordered phase. We discuss experimental setups for measuring the scalar susceptibility. The conductivity of the O (2 ) theory (relativistic superfluid) is a scalar response and therefore exhibits suppressed absorption below the Higgs mass threshold, σ ∼ ω 2 d + 1. In layered, short coherence length superconductors, (relevant, e.g., to cuprates) this threshold is raised by the interlayer plasma frequency.
