... Across Physics and Astronomy
Session 2 - March 2023#
Panel discussion - Using Data to answer scientific question#
Speakers
Dr Charanjit Kaur
Dr Pierre Ghesquierre
Cat
Astra
Andrew Cassidy
**Chair**: Amber
Variability of data processing between disciplines
Hard, we don’t speak the same language
Data from different sources, how to compare
Amber - Building a molecular Nitrogen clock#
Searches for dark matter
Are fundamental constants constant?
Standard model says yes but standard model
QSNET consortium
µ (proton - electron mass ratio) vs alpha
Quantum clock#
clock:
oscilator
reference
counter
same with quantum - laser interacting with molecule oscillating from state 1 to state 2
Natasha - Sussex#
Note
Very cool explanation of what BEC is and nice results
Bose Einstein condensates - quantum phase
condensed matter and quantum information
Bose einstein condensates#
rubidium
Low T: de Briglie wavelength
T = Tcrit: Bose Einstein condensation
Qauntum phase#
Radio frquency dressing#
Matter wave interference
Is it coherent splitting
Timothy Leese Scalable Quantum computing#
Note
Cool introduction to quantume sensing, Great diagram
Qubits -> Quantume sensors (ex quantum clocks)
Qubit lose information through decay & dephasing
How can we reduce the information that we loose
Great diagram
Siobhan Patrick Quantum computing#
Note
Very comprehensive, nice work
cold neutral atoms manipulated by light
qubits
How can you trap atoms ?
Optical
Quantume gates#
NOT (1 qbit)
CNOT (2 qbit)
Rydberg atom
Laser cooling: Magneto optical trap (MOT)
3 pairs of beams
Dipole traps: trap small groups or indiv atoms
Measuring Temperature#
Gas expansion
Discussion Panel: Open Dialogue in Physics#
How did the dialogue kept open during covid#
Opening Keynote: Catxere Casacio#
Note
On December 10, 2008 Osamu Shimomura, Martin Chalfie and Roger Tsien were awarded the Nobel Prize in Chemistry for “the discovery and development of the green fluorescent protein, GFP
Life on the edge (John templeton foundation) - Surrey university
5 groups - Cat is: Experimental quantum biology in the lab
Coherence: ripple - interference (classical but quantum correspondance)
Decoherence: : big waves,
Edge means understanding the processes at the interface of quantum and classic (between femto and pico second processes)
Sample: Green fluorescent protein - 3 aminoacides (chromophore)
Absorption 10-15 s
Emission 10-9 s
What happen in between ?
Dimers protein, energy interaction, coherency
Attach cysteine allow attachement of protein to DNA
Absorption/Emission same -> Attachment to DNA doesn’t modify physical properties of GFP
Anisotropy (What does it mean in that context)
Transient Absorption spectroscopy
Session 1 - September 2022#
What a delightfull parentheses that was on this early September 2022 in Southampton at the student conference Open Dialogues across Physics and Astronomy. Wonderfully chaired by Astra Sword who invited students and accademics from phyics, astronomy and related fields, to welcome interdisciplinary talk and open dialogues around underlooked issue in Physics and Accademia. This conference was a perfect example of kindness …
My contribution#
Poster that I presented
Conference highligts#
Mes “coups de coeur”
Diversity and inclusion#
Great representation
Conference dinner (of course)#
It’s been a while since I haven’t done a Conference, the reason being that since two years, they are mostly online. I mean, what is the point if you can’t have a chat with your
Note Catxere
I couldn’t finished my sentence during our discussion so here it is.
When I imagine a new world, I think about it as a planetary scaled Communist organisation, in the sense of global collection , organisation and distribution of the Earth ressources. As such, the whole humanity can ensure that we don’t extract more than what we actually need and can perform those tasks in the most possible efficient way (energy saving). Of course, I don’t see the Earth governed by a single human and deep in my heart, I also like my country and it’s borders.
