#### 3π个莫比乌斯带上的超导量子悬浮

Superconducting Quantum Levitation on a 3π Möbius Strip

A simple loop has two sides.

You can’t get

from the red side to the green side without

crossing the edge.

If you cut the loop,

twist one end by 180 degrees, or π radians, and

connect them again, you will have a Möbiusstrip: a mathematically non-orientable surface

with only one boundary. Now,

you can travel

along the red side to the green without going over the edge.

If you twist the end again for a

total of 360 degrees, or 2π radians,

you will have a twisted loop.

You again can’t get from the red side to the green side.

If you twist the end a third time for a total of 540 degrees,

or 3π radians, you will

again have a Möbius strip.

Our demonstration is a 3π Möbius strip track.

By the time the superconductor has gone around

the loop once, it has rotated 540 degrees about its own axis.

This animation shows you how to twist a

loop 540 degrees to get a 3π Möbius strip track.
