Theories of Everything with Curt Jaimungal · Roger Penrose and Ivette Fuentes: A Bold New Test of Gravity · 25 Nov 2025 podcast

But one of the atoms, he um well, one of the arms of the interferometer is such that the atoms are at rest.

So he basically uh acts with uh fields on on the atoms such that he uh cancels gravity and the atom is just levitating there.

And in the other arm he uses again uh fields

To kick

the other uh branch of the interferometer and let then uh this atom go in in free fall.

So this is done with what we call an atom chip.

So this is a chip where you can build like a little experiment inbuilt in the chip that produces you do like wires and they produce uh magnetic fields.

And the whole system is controlled by this uh by this chip through the magnetic fields.

So you use a magnetic field to make one of the branches

levitate and the other one to give a kick to the atom.

So the magnetic fields sort of change the internal

um uh states of the atoms to some states that are C magnetic fields and uh others that are uh um that don't to to produce this sort of hybrid interferometer where one of the atoms is um uh addressed in the lab and the other one is in free flow and then he interferes them and he sees uh the fringes.

And what he

finds in the fringes is that there is an oscillation which has a very special type of oscillation because uh well oscillations obviously always depend on time but this uh type of oscillation depends on the cube

Of time.

Okay.

Then maybe Roger ha can explain the significance of that.

Uh okay, so so let me uh like clarify a few things and talk about the experiments that are taking place by other groups and so to put like the whole thing in in in context.

I mean the the the reason why uh Roger says that Ron is uh ex experiment is very far away is because effectively the experiment of Ron is with one atom.

And um well maybe it's good to also d make the distinguish between
