Revealing hidden spin: Unlocking new paths toward high-temperature superconductors

In the 1980s, the discovery of high-temperature superconductors known as cuprates upended a widely held theory that superconductor materials carry electrical current without resistance only at very low temperatures of around 30 Kelvin (or minus 406 degrees Fahrenheit). For decades since, researchers have been mystified by the ability of some cuprates to superconduct at temperatures of more than 100 Kelvin (minus 280 degrees Fahrenheit).

This is really fascinating!  And hopefully it will lead eventually to room-temperature superconductors.

Turning diamonds’ defects into long-term 3-D data storage

Turning diamonds’ defects into long-term 3-D data storage

With the amount of data storage required for our daily lives growing and growing, and currently available technology being almost saturated, we’re in desparate need of a new method of data storage. By Siddharth Dhomkar and Jacob Henshaw

The standard magnetic hard disk drive (HDD) – like what’s probably in your laptop computer – has reached its limit, holding a maximum of a few terabytes. Standard…

Spin-Magnetics

Magnetism is the result of subatomic particles spinning in sync. Electrons , charged particles have  a spin and there is two directions up or down.  When the spins align in opposite direction they cancel but when they are aligned they do not and a magnetic moment is formed and this results in magnetism.

Question: Heisenberg picture spin precession ([1] pr. 2.1)

For the spin Hamiltonian

\begin{equation}\label{eqn:heisenbergSpinPrecession:20} H = -\frac{e B}{m c} S_z = \omega S_z, \end{equation}

express and solve the Heisenberg equations of motion for \( S_x(t), S_y(t) \), and \( S_z(t) \).

Answer

The equations of motion are of the form
