New Theory and Space X-Rays – What Does It Entail?

  • High-energy-density physics (HEDP) is a relatively new subfield of physics intersecting condensed matter physics, nuclear physics, astrophysics and plasma physics.
  • The new theory is going to be tested using a laser structure.
  • If the experiment is successful the physics textbooks will be rewritten.

There is a group of physicists specifically dedicating their work to the physics of high energy densities. High-energy-density physics (HEDP) is a relatively new subfield of physics intersecting condensed matter physics, nuclear physics, astrophysics and plasma physics. It has been defined as the physics of matter and radiation at energy densities in excess of about 100 GJ/m^3.

High energy density physics studies the collective properties of matter under extreme conditions of temperature and density. Not surprisingly, this study of extreme science has considerable overlap with astrophysics and nuclear weapons physics, as well as inertial confinement fusion research. It is a highly specialized and narrow subfield.

In addition, the entire field of relativistic HED physics, also known as high-field physics, was enabled by the invention in the early 1980s of so-called chirped-pulse amplification of laser light, a technique that generated laser electromagnetic fields of unprecedented intensities.

The physicists in this unique sub field of physics are extremely passionate about the matter inside planets and one of the main component of this subfield is highly classified nuclear weapons work and research, which is part of the defense spectrum.

A new work has become available by a very distinguished physicist Suxing HU, who works in the Laboratory for Laser Energetics, University of Rochester in New York. His latest work, in collaboration with French physicists, is titled “Interspecies radiative transition in warm and superdense plasma mixtures.”

The work includes the new theoretical idea that interatomic radiation transitions can occur at the high pressure.  A radiation transition is simply a jump of an electron into the orbit of a neighboring electron within a single atom. Hu’s idea is that interatomic radiation transitions can occur at high pressures.

The new proposed theory by Hu brings complexity to the spectral method of identifying substances from the cosmic depths. When atoms come together the electron shells overlap due to high pressure. Electrons become “shared.” You can’t tell which is which. According to Hu, under these conditions, radiation transitions between the electron orbits of not one, but different, atoms are possible. The energy of the emitted or absorbed photon is different from what it would be at the transition inside the native atom.

Three cases are calculated for Fe-only, Zn-only, and Fe–Zn mixture having 1s vacancy at ρ = 1000 g cm−3 and kT = 50 eV, using density-functional theory (DFT) with ABINIT.

Some electrons fly in a circular orbit, others in a dumbbell-shaped orbit and that there are also hybrid orbitals. Inside the atom, transitions are possible only to the orbit whose shape differs from the one from which the electron jumps. When pressure mixes atoms into an incomprehensible heap, transitions between identical orbits, according to Hu’s theory, become possible. As a result of the new allowed jumps of electrons between atoms, new lines should appear in the spectrum of x-ray radiation coming from astronomical objects,

As a result of the new allowed jumps of electrons between atoms, new lines corresponding to previously unknown radiation transitions should appear in the spectrum of x-ray radiation coming from astronomical objects. These lines must be interpreted correctly.

The physicists that are part of this project plan to test the new theory by using a laser installation, while transferring the substance to an exotic state.  In 2018, NASA created a rare, exotic state of matter in space. NASA was able to cool a cloud of rubidium atoms to ten-millionth of a degree above absolute zero, producing the fifth exotic state of matter in space. The experiment also now holds the record for the coldest object we know of in space.

Hu’s experiment will be done on our planet, hence an exotic state can only be held at best for a couple of nanoseconds. If the test is successful it would lead to a completely different approach for physicists and amendments would have to be made in the academic world.
