Metaphysical Thoughts - Making Quantum Mechanics Logical

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      ...

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...

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...

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

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...

In our previous blog post we analyzed Anthony J. Leggett's claim that a circulating superconducting current in a loop cannot decay to a ...

UPDATE April 19, 2022: If we have a closed electric circuit where a part of the circuit is superconducting, and there is a potential wall wh...
