Quantum sensing on a chip / techxplore

@vzn For some strange reasons, I suddenly believed to have more time again, and a friend (or two) tried to motivate me to write a blog post about the logic of "union closed sets" / the logic of "formal contexts". Well, I decided to try with an easier topic first, an idea for how to construct a concrete non-standard model of some weak axiom system for the natural numbers. That took me from beginning of March till mid August, and took totally unexpected turns.

At least the idea that writing a blog post would be a good motivation to spend time working on a subject proved to be true. You are always nearly finished, when in fact would are still months away from finishing it, you just don't know.

@ThomasKlimpel hi, youre talking about this one? gentzen.wordpress.com/2019/08/17/… wow what an epic... do you have any time for QM these days? there have been so many developments since we last discussed it at length... went and looked and Neumaier more closely... alas have nobody to discuss it with :( (initially very dynamic+promising+energetic) new face MA already disappeared also, lol :(

@vzn "new face MA already disappeared also" well, I waited a bit till he took a pause...

@ThomasKlimpel lol dont feel its nec to wait a few days... you seem to be in a different time realm over there... (alas) looks like he "paused" all the way to oblivion :( o_O

"do you have any time for QM these days" yes, read papers and books, was at a conference, watched Bernays lectures

@ThomasKlimpel which conference? do you still work on QM as part of your job?

Thinking harder about "interpretation of experimental observations" these days. Even quantum mechanics itself is emergent from quantum mechanics, but that is not how one calls this. Not sure whether there is a proper name for it.

microscopy-conference.de

cool, do you work with microscopes? worked with nikon/ zeiss rigs many years ago.

QM is still part of my job. But my recent experiences made me question whether my understanding is appropriate enough. One can do some math, but experiment can reveal many different aspects. Maybe I will dive deeper into arxiv.org/pdf/1807.11710.pdf now, to see whether the gap to the experimental data will get smaller.

@ThomasKlimpel seem to recall youre working in chip fabircation? for a major corp? are you looking at electron dynamics in small gate widths? or electron microscope dynamics? etc

Well, our customers and partners show me their clean room and (electron) microscopes when I visit, but I never operated one myself. But I do get to see their measurement data, detector signals, and can compare simulation against reality.

Do you see the blue flag (offensive/spam)? Here is my favorite episode of that comic: existentialcomics.com/comic/287

I look at electron dynamics and charging dynamics, mainly just the interaction between electrons and matter. The electric field in the electron microscope (as a whole) is part of the simulation, because it impacts the charging dynamics in the sample, and it influences which signals can be detected, and which image distortions are caused by charging.

@ThomasKlimpel are you talking about in chat? lol comic reminds me of a Lovecraft graphic novel read recently...

yes, I am "talking about in chat"

@ThomasKlimpel are you working for a corp? research scientist?

@ThomasKlimpel did you get a flag notice? think those are somewhat randomly issued across users...

No idea why it got flagged, but it was talking about existentialcomics.com/comic/45

@ThomasKlimpel some flags are spurious/ near random. aka "boy who cried wolf"

The only corporation that I worked for was Synopsys (today ~10.200 employees, was at 7000-8000 employees in my time). Now I work for a small company (< 50 employees).

have heard of synopsys. so you tune electron microscopes or something like that?

I develop a simulator. You wonder what the simulator is used for, I guess.

@ThomasKlimpel is the main product of your company a simulator? yes ofc wonder what its for ... electron microscopes apparently...

Well, I mean you wonder why one wants to simulate an electron microscope, i.e. what our partners and customers do with the simulator. The main product of my company is not that simulator, but a product used for ebeam lithography data preparation.

In a certain sense, your idea to "tune electron microscopes" might be not too far off, even so the electron microscope itself is not really modified. But it might be used differently, and the data it produces might be interpreted differently. Say you use the electron microscope to find defect. Are you sure there are none, just because the image seems to show none?

cool stuff TK! theoretical + applied physics! not a common combination! still fervently wish you would apply all your mathematical prowess to QM revision prj at least occasionally! :)
