Searching for light dark matter by tracking its direction with quantum sensors

Dark matter is an elusive type of matter that does not emit, absorb or reflect light, interacting very weakly with ordinary matter. These characteristics make it impossible to detect using conventional technologies used by physicists to study matter particles.

As it has never been observed before, the exact composition of dark matter remains unknown. One proposed theory is that this elusive type of matter is comprised of light particles with very small masses, below 1 eV (electronvolt), which behave more like waves than particles.

Researchers at the University of Tokyo and Chuo University recently explored the possibility of searching for sub-GeV dark matter using quantum sensors, advanced systems that rely on quantum mechanical effects to detect extremely weak signals.

🌕 Einstein “is the Moon there when no one looks?” 🌖

Einstein never liked the idea that nature is uncertain and he once said “does that mean the Moon is not there when I am not looking at it”. He believed we live in an orderly Universe which is fundamentally rational and that there should always be a reason why thing happen. But there is a way to have the objective Universe of Einstein and the uncertainty of quantum physics and that is by explaining quantum mechanics as the physics of ‘time’ with the future as an emergent property.

In this radical theory the mathematics of quantum mechanics represents the physics of ‘time’ as a physical process with classical physics representing process over a period of time as in Newton’s differential equations. This is a process formed by the spontaneous absorption and emission of light photon energy. This forms a continuous process of energy exchange that forms the ever changing world of our everyday life.

The Universe is a continuum with the future coming into existence photon by photon with each new photon electron coupling or dipole moment. This forms the movement of positive and negative charge with the continuous flow of electromagnetic fields.

Consciousness in the form of electrical activity in the brain is the most advanced part of this process and can therefore comprehend this process as ‘time’. With a past that has gone forever and a future that is always uncertain in the form of a probability function or quantum wave particle function that is explained mathematically by Schrödinger’s wave equation Κ. Therefore each individual is in the centre of their own reference frame as an interactive part of this process. With their own time line from the past into the future being able to look back in time in all directions at the beauty of the stars! It is this personalization of the brain being in ‘the moment of now’ in the center of its own reference frame that gives us the concept of ‘mind’ with each one of us having our own personal view of the beauty and uncertainty of life.

It is not that there is uncertainty if the Moon is there or not if nobody looks. It is that the physical act of looking will form new light photon oscillations or vibrations relative to the actions of the observer in a continuous flow of cause and effect. The wave particle duality of light is acting like the bits or zeros and ones of a computer. This forms an interactive process continuously forming a blank canvas that we can interact with turning the possible into the actual! Any observation of the Moon will be over a period of time with the wave nature of light explaining diffraction, interference, reflection and refraction. But the particle nature of light the ‘photon’ will only come into existence when the light comes in contact with the lenses and mirrors of the telescope being used. And finally with new photons be formed in the eye of the observer the uncertainty of the observation will be completed using both the wave and particle nature of light!

What we see in our everyday life as an uncertain future is formed by a physical process that at the smallest scale is represented mathematically by Heisenberg’s Uncertainty Principle ∆×∆p×≄h/4π with the Planck constant ħ=h/2π being a constant of action in the dynamics geometry of space and time! This theory takes quantum potential, electrical potential and gravitational potential and combines them into one universal process. That explains why we all have a potential future in our everyday life that is always uncertain. This is done by making the future an emergent property energy ∆E slows the rate that time ∆t flows creating a future relative to the energy and momentum of each object or life form. For in this theory creation is truly in the hand and eye of the beholder with an objective reality in the form of a dynamic interactive process that forms an infinity of possibilities.

Real-life experiment shows Niels Bohr was right in a theoretical debate with Einstein

Scientists in China have performed an experiment first proposed by Albert Einstein almost a century ago when he sought to disprove the quantum mechanical principle of complementarity put forth by Niels Bohr and his school of physicists. Bohr claimed there are properties of particles that cannot simultaneously be measured. The new result backs up the Copenhagen school yet again, with the potential to shed light on other, less settled questions in quantum mechanics.

When they met at physics conferences, Albert Einstein and Niels Bohr liked to kick back and debate about quantum mechanics. Einstein, always skeptical of the standard picture of quantum mechanics then being developed, liked to claim he had found holes and inconsistencies in Bohr’s interpretation, and Bohr was always up for the challenge.

At the 1927 Solvay conference in Brussels, the two Nobel Laureates had perhaps their most famous parley, with Einstein famously proclaiming, “God does not play dice with the universe.” In particular, Einstein proposed an experiment he thought would reveal the essential contradiction in the principle of complementarity, which held that pairs of properties of particles, such as position and momentum, and frequency and lifetime, cannot be measured at the same time. Complementarity undergirds the concepts of wave-particle duality and Heisenberg’s uncertainty principle.

Hunting for dark matter axions with a quantum-powered haloscope

Axions are hypothetical light particles that could solve two different physics problems, as they could explain why some nuclear interactions don’t violate time symmetry and are also promising dark matter candidates. Dark matter is a type of matter that does not emit, reflect or absorb light, and has never been directly observed before.

Axions are very light particles theorized to have been produced in the early universe but that would still be present today. These particles are expected to interact very weakly with ordinary matter and sometimes convert into photons (i.e., light particles), particularly in the presence of a strong magnetic field.

The QUAX (Quest for Axions/QUaerere AXion) collaboration is a large group of researchers based at different institutes in Italy, which was established to search for axions using two haloscopes located in Italy at Laboratori Nazionali di Legnaro (LNL) and Laboratori Nazionali di Frascati (LNF), respectively.

This Quantum Gas Refuses To Follow the Rules of Classical Physics

Researchers at TU Wien have developed a one-dimensional “quantum wire” using a gas of ultracold atoms. In this system, both mass and energy can move freely without friction or energy loss. In everyday physics, transport refers to the movement of something from one place to another. This can inclu

Sharp Diffraction Pattern Produced by Atoms Passing Through Graphene

Researchers have generated high-quality atom diffraction data from graphene, which could lead to new ways to measure surface interactions.

A beam of neutral atoms striking a material can produce a diffraction pattern that is sensitive to short-range interactions between the atoms and the surface. Building on recent developments, Pierre Guichard from the University of Strasbourg in France and collaborators have now used a fast hydrogen beam to probe single-layer graphene, producing the sharpest graphene diffraction patterns to date [1].

Early atom diffraction experiments predominantly looked at reflection, because atoms transmitted through a material tend to lose their wave-like coherence. Recently, however, transmitted atoms were shown to produce a diffraction pattern from single-layer graphene [2]. The trick was to use fast atoms that traverse the target quickly, minimizing coherence-destroying interactions.

Twisted light-matter systems unlock unusual topological phenomena

Properties that remain unchanged when materials are stretched or bent, which are broadly referred to as topological properties, can contribute to the emergence of unusual physical effects in specific systems.

Over the past few years, many physicists have been investigating the physical effects emerging from the topology of non-Hermitian systems, open systems that exchange energy with their surroundings.

Researchers at Nanyang Technological University and the Australian National University set out to probe non-Hermitian topological phenomena in systems comprised of light and matter particles that strongly interact with each other.

Researchers discover a new superfluid phase in non-Hermitian quantum systems

A stable “exceptional fermionic superfluid,” a new quantum phase that intrinsically hosts singularities known as exceptional points, has been discovered by researchers at the Institute of Science Tokyo.

Their analysis of a non-Hermitian quantum model with spin depairing shows that dissipation can actively stabilize a superfluid with these singularities embedded within it. The work reveals how lattice geometry dictates the phase’s stability and provides a path to realizing it in experiments with ultracold atoms.

In the quantum world, open quantum systems are those where particle loss and directional asymmetry are fundamental features. These systems can no longer be described by conventional mathematics.
