Our work removes the motivation for supersymmetry: there are no divergences

›
UPDATE May 13, 2022: We made an elementary error by assuming that the Higgs particle is free. It is not free: its lifetime is very short. Th...

Elastic time crystal: a model of superconductivity

›
In our blog post on April 22, 2022 we tried to explain a superconducting current in a linear wire which forms a loop with an ordinary wire. ...

Electron movement in a wire: some crude numbers

›
Let us have a 1 cm thick and 1 meter long wire made of a metal. Its weight is roughly 1 kg, and it contains some 10²⁵ atoms. There are      ...

Problems with time crystals and superconductivity: a perpetuum mobile is created?

›
In an ordinary crystal, the lowest energy state is static, except of zero-point vibrations of the atoms. In a time crystal, the lowest energ...

Resistivity and phonons

›
Let us look at how phonons cause resistivity in a metal. Then we can try to figure out how this resistance disappears in a superconductor. h...

Magnetic flux quantization through a superconducting loop

›
In 1961 two independent research groups discovered that a small superconducting loop of a size ~ 1 micrometer only allows a magnetic flux   ...

Orbital angular momentum can be any fraction of reduced Planck constant in a coil

›
We use the particle-in-a-box model. We make a "coil" from a tube so that the ends of the tube are joined. The particle is inside t...
