S… Speaker 1 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

Physicists love particles,

0:02

S… Speaker 1 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

and with good reason.

0:04

S… Speaker 1 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

Almost everything in the universe is made up of particles,

0:06

S… Speaker 1 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

so the physicist's approach to understanding the universe is to understand the particles that make it up.

0:10

S… Speaker 1 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

If you want to discover and catalog new particles,

0:13

S… Speaker 1 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

which physicists do,

0:14

S… Speaker 1 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

here are three approaches you can take.

0:16

S… Speaker 2 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

First,

0:17

S… Speaker 1 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

you can take old particles we already know stuff about and just stick them together to build new

0:21

S… Speaker 1 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

composite particles.

0:22

S… Speaker 1 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

That's what chemists and molecular biologists spend a lot of their time doing,

0:25

S… Speaker 1 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

and it's kind of like figuring out what you can build with Legos.

0:29

S… Speaker 1 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

Second, you can smash old particles together with ever -increasing violence,

0:32

S… Speaker 1 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

either hoping to break an old particle apart into previously unknown constituents,

0:36

S… Speaker 1 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

or to excite a new particle into existence from the quantum fields that underlie

0:40

S… Speaker 1 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

all reality.

0:41

S… Speaker 1 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

Sometimes this works,

0:42

S… Speaker 1 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

and the smashing reveals an entirely new,

0:44

S… Speaker 1 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

fundamental building block of the universe,

0:46

S… Speaker 1 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

like quarks,

0:47

S… Speaker 1 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

or the Higgs boson.

0:48

S… Speaker 1 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

But most of the time it just makes a big mess,

0:51

S… Speaker 1 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

an explosion of old particles we already know about.

0:53

S… Speaker 2 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

Third,

0:54

S… Speaker 1 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

you can put old particles in new environments,

0:56

S… Speaker 1 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

so that they behave differently.

0:58

S… Speaker 1 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

or put old particles together in new ways so that new particle -like behaviors emerge

1:02

S… Speaker 1 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

through their collective quantum interactions.

1:04

S… Speaker 2 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

For example,

1:05

S… Speaker 1 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

in certain crystals,

1:06

S… Speaker 1 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

the particles that move around are not electrons themselves,

1:09

S… Speaker 1 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

but in fact holes or gaps in a densely packed sea of electrons.

1:12

S… Speaker 1 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

Or when you make certain materials really,

1:14

S… Speaker 1 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

really cold,

1:15

S… Speaker 1 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

free electrons in them stop acting like electrons and team up in pairs to

1:19

S… Speaker 1 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

act like weird electron -only atoms that move around with essentially no resistance.

1:24

S… Speaker 1 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

Or, when you make certain metals really cold,

1:26

S… Speaker 1 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

electrons in them start acting as if they were a thousand times heavier than normal.

1:30

S… Speaker 1 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

Or, if you make a super thin,

1:31

S… Speaker 1 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

essentially two -dimensional sheet of gallium arsenide with a perpendicular magnetic field

1:35

S… Speaker 1 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

and a parallel electric field and make it really cold,

1:38

S… Speaker 1 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

electrons start behaving as if they had an electric charge that's a fraction of what they normally

1:42

S… Speaker 1 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

do. Or,

1:43

S… Speaker 1 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

if you force electrons into a special one -dimensional line,

1:46

S… Speaker 1 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

particles that move back and forth along that line look like electrons,

1:49

S… Speaker 1 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

except separated so that some of them have the charge of an electron but no spin,

1:53

S… Speaker 1 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

while others have the spin but no charge.

1:55

S… Speaker 2 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

Or,

1:56

S… Speaker 1 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

if you cool helium down super super cold,

1:58

S… Speaker 1 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

you'll find emergent particles that behave like Higgs bosons.

2:02

S… Speaker 1 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

These emergent Higgs bosons were first discovered in 1973,

2:06

S… Speaker 1 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

40 years before the Higgs boson fundamental particle was discovered at the

2:10

S… Speaker 1 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

Large Hadron Collider by violently smashing together protons.

2:13

S… Speaker 1 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

Of course, these particles that emerge when you put collections of electrons together in materials

2:17

S… Speaker 1 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

are not fundamental constituents of the universe,

2:19

S… Speaker 1 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

but they're far more diverse and bizarre and weird and cool.

2:23

S… Speaker 1 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

And unlike searching for fundamental particles where you just have to wait and see what nature

2:27

S… Speaker 1 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

has in store, we can actively find and curate new emergent particles

2:31

S… Speaker 1 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

simply by making different weird materials that allow their emergent properties to come

2:36

S… Speaker 1 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

to life.

2:36

S… Speaker 2 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

Plus,

2:37

S… Speaker 1 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

materials with emergent particles have real and far -reaching practical technological use.

2:41

S… Speaker 1 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

in electronics,

2:42

S… Speaker 1 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

computer chips,

2:43

S… Speaker 1 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

levitating high -speed trains,

2:45

S… Speaker 1 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

and even the magnets and detectors used to discover the Higgs boson at the

2:49

S… Speaker 1 (How To Discover Weird New Particles - Emergent Quantum Quasiparticles)

Large Hadron Collider.
