I am going to give presentation on our developed automatic robotic device ALSA for crystal coalignment for #neutrons. Come to see my talk at #APSMarch today from 12:30 PM in the room M100C. @Mecademic @PhotonicL

@josephpalbanese It is an abbreviation of the chemical composition: Pb10-xCux(P(O1-ySy)4)6O1-zSz --> PCPOSOS

🧵Thread on the talk:
1) at the beginning Dr. Hyun-Tak Kim also mentioned other collaborators, see slide.

Talk on #LK99 doped with sulfur at #apsmarch is going to start. The small room is full and the team seems very confident https://t.co/gwc4a8ThEa
People in the auditorium remain very sceptical. Do you have some questions to ask the Dr. Kim Hyun-tak?

[Petr Čermák @petrscience]

@ASM65617010 Maybe @vikmez stayed in the session?

[Petr Čermák @petrscience]

@ASM65617010 No and no, I switched to a machine learning session so I can't report on that.

[Petr Čermák @petrscience]

@andrewmccalip I fully agree.

8) The talk did not bring so much new information 😞. I was expecting that the presenter will bring the magnet 🧲 and the sample to show it to the audience live. The whole thing remains highly speculative and imo improbable.

[Petr Čermák @petrscience]

7) Conclusions... Thanks Dr. Kim Hyun-Tak for presentation!

[Petr Čermák @petrscience]

@JV_today_ I remain sceptical as before. If there is an SC phase, even if it is very small, it should be possible to cut it out of the sample and measure precisely. And sure, there is still no peer reviewed publication.

[Petr Čermák @petrscience]

@mformanek88 Imo not anything new, they are confident that the sample is a superconductor, but it is clearly a multiphase sample which could also explain shown behavior.

@fawwest I will post photos from the slides with my comment.

[Petr Čermák @petrscience]

@rider_nimbus Neither question answered fully. A non-conclusive video of the sample behavior above the magnet was shown. A sample "suddenly" falls down on the edge which was explained by reaching a critical field.

[Petr Čermák @petrscience]

@rider_nimbus There were two questions: 1) how partially levitated sample behaves when moving from center to edge of the magnet 2) my question: how reproducible is your procedure of sample preparation.

@DZakutna Thanks for a great talk, let's hope the community will grow in the future ✌️
