Jacobsen also explains that fear should not prevent you from learning quantum mechanics.

Jacobsen now tells us that the spin accumulation can have a 2000+ times greater effect than the non-superconducting counterpart, and also shows us that there are Nano-Squids as well.

Jacobsen shows us basic matrix algebra

But! Using these equations she has found a peak in the density of states, the density of the triplets they love so much.

Jacobsen also wants to model her work. This requires very tough mathematics!

DOS in this case does not refer to the infamous Disk Operating System, but rather the famous Density Of States.

The problem is to find methods experimentally to find out if you have triplets or not

And now Jacobsen wants to know how to control them. Both herself and her team have worked hard on this research.

Spin triplet; two half-spin particles (electrons). We then have three allowed values of the spin component; ms = 0,1,-1

Now Jacobsen comes with some amazing details: If we have a triplet of electrons with equal spin, the decay time is independent of the magnetism.

Now comes an explanation of superconductivity, a concept known to have caused headaches worldwide.

the world record high-temperature superconductor is at 203 K, but the pressure is insane!! No gain in the higher temperature, some would argue!

Some of the metals surrounding it also has some superconducting properties but reaching this regime is tough as you need temperatures down to 10 K.

that is materials for superconductors

The materials used are typically Fe, Co, Ni and some heavy metals

Jacobsen now shows a photo of a superconductor material floating in a magnetic field. Smart people tend to use the term "quantum locking" when referring to this

Jacobsen works for QuSpin, a leader internationally within spintronics.

I wonder if they're able to do room temperature superconductors too?

And the lifetime of the spin is surprisingly short; less than a nanosecond. That's like a nanometer in time.

Spin-transfer torque has a limitation in that the current needs to be very high meaning that stuff gets warm.

Jacobsen is able to split the spins using spin-orbit coupling .

We can utilize this in spin imbalance materials; f.ex. in ferromagnetic materials which is used amongst others in memory applications

The spin is a quantum property and exists in two different half integer quanta; spin up and spin down. Plus minus 0.5.

Spintronics: Spin-electronics; an extra degree of freedom.

Another "Scotish" contribution

We have now begun with Sol Jacobsen who will speak about the future of information technology.
