- Scientists like to organize phenomena in schemes with simple rules but ample predicting power. The periodic table is one of the most successful examples of this: just by labeling the different possible orbitals of a hydrogen atom, we can predict with great accuracy the existence and properties of most elements and alloys. But in any good classification scheme, outliers become apparent and hint at a necessary refinement of physical laws. What is missing in the periodic table is that matter is not formed by one but by billions of billions of atoms together, and electrons in orbits around each atom can be fundamentally altered by their surroundings, altering their weight and spin, among other properties. In this talk, Dr. Raquel Queiroz will describe how we now understand that electrons behave as if they live in a curved space, where most physical properties are dictated by the geometry itself.
She will also introduce the new notion of quantum geometry in quantum materials and its crucial role in determining properties and phases of matter. She will discuss how quantum geometry is essential to protect emergent phases where interactions between electrons are strong and electrons behave in remarkable ways, such as those where electrons pair up and condense into a macroscopic quantum state or phases where electrons are broken into independent fractions with new quantum statistics.
Raquel Queiroz is an Assistant Professor of Physics at Columbia University and a Visiting Scholar at the Center for Computation Quantum Physics, Flatiron Institute in New York City. She received her PhD from the Max Planck Institute for Solid State Physics in Stuttgart, Germany, in 2015 and was a postdoctoral fellow at the Weizmann Institute of Science in Israel from 2016 until 2021. In 2022, she established her group at Columbia University, where she studied topological and geometric properties of solids, primarily how quantum geometry affects electronic response, collective phenomena, and behavior in the presence of disorder. Her work is deeply motivated by current experimental findings and a constant dialogue with experimental colleagues.

Great lecture by Dr.Queiroz. But man, she deserved better audio and video quality. Audio was terrible.
We are so sorry! We are working on upgrading our system. Thank you for the feedback.
With luck and more power to you.
hoping for more videos
I get the feeling that she is on to something deep and interesting, but I can't describe it. It would be helpful if she gave some examples in which her geometry is used to predict properties of a solid that can be confirmed by experiment.
Great lecture 👌
As cool as the qauntom physics key to the cosmos is I can't say I enjoyed growing up in its wake as our high schools were almost overreactionary about it maybe lol. Name & order ,grand myth & men teaching lol
I would've enjoyed Triangulating thermodynamical systems movement of thought era much more .less platonic...
I hope I live to see the end of this mathematical age I think I agree with newton on the paradoxical reality
In this 3rd and final frontier, we will be using a new tool of measure used to do so. Maybe the methodology is computational but it wont text or observational I don't think 🤔
More relational & total were we can ignore the prenticious views of scale or reluctant acceptance in the more testsble key within...❤🎉
hello beautiful presentation despite the technical difficulties , so what happens to the electrons field when it collides with the proton ,does it folds inside or vanishes in electromagnetic energy (waves )and if so what is the spectrum l ?is it correct to say that electrons interact with each other with the same force ;because they have the same charge, same electric field ,the only thing that is changing is their orbit aka different frequency so the h constant must derives from the electrons charge ,which in the first case applies all the way to the nucleus and some how when a neutron decays it spats it out with a subatomic mechanism that is effected by the neutrons state, in the cases of neutron decay , does the Heisenberg principle apply?
Really interesting. Condensed matter technology will be the latest frontier.
How is time and amplitude related? If the universe had a base frequency (space-time oscillating) then time would only exist between matter. Get time on the left hand side of the Schrodinger equation as a function of amplitude.
You manufactured the perfect sine waves of C and D which reminds me of photons presented to measuring apparatus especially coincident to an expected result.
Masses of photons or electrons behave across a probability distribution well mirrored by assuming a wave function that is a solution to a linear differential equation. I speculate a granular composition of space/time that slightly alters the path of individual particles.
Sorry guys - I gave up trying to follow this. The audio was awful, I really couldn't understand what she was getting at, so I stopped at 5 mins. If things get better later I apologise, but this presentation was terrible!
Yeah. It wouldnt be so bad if the CC closed caption didnt give incorrect text all the time. But, in her video she says moiré lattice and its rendered as 'mo latice' in the CC.

Change in geometry is power. Like a to a square or inverse squares. Related only through time. That's why quantum effects of numbers. Distribution of sequences within a number series.
The questions lol...pop sci ahh crowd
Another Utube science lecture proves the aether but remains ignorant of the fact.
all mass has the same geometry. just different frequencies. energy is mass moving through time plus it's momentum through space. momentum through space varies.
all mass moves from the past to the present at the same time. just at different speeds. time dialates accordingly. Light keeps a constant speed by changing wavelength.
pi is 1 plank length. mass needs 8pi to be 3d. Light needs 2.
Poor audio quality
