I read and talked to many ppl about these concepts, but you know how to intuitively build the picture. Hats off!

[edulab]

Every time I watch the lectures, I understand new things

[ronaypronayp]

Молодец, брат всё-таки наши специалисты наводят порядок в куче экспериментов по JJ

Electrons in the conduction band at low temperatures are combined into a Bose-Einstein gas, which has the property of superfluidity, therefore, the so-called superconductivity is actually superfluidity of an electron gas without the resistance of the crystal structure. The ability of a substance in a special state, which occurs at temperatures close to absolute zero, to flow through narrow slits and capillaries without friction. This is superfluidity.

[nickpenacl]

therefore, what's the difference between quantum tunneling and J. junction ?

[sundaijing]

Can I have the ppt file? The lecture is so nice.

[LydellAaron]

Would a semiconductor tunneling effect occur when using a difference amplifier op-amp to detect zero crossings of a sinusoidal signal?

[Max-eovx]

Good lecture but poor flow compared with lecture 13 which was excellent.

[salamatburj]

Can someone please elaborate more how in (30:56) magnetic field adjusts the phase? Aren't they in the same phase because it is one just one metal?

Thank you!
