I thought this was a hilarious comment, for what it's worth.
Pretty funny. Having taught low-temperature condensed matter labs, a big part of the grade is figuring out what went wrong, and either correcting for it, or at least acknowledging that it went wrong. The student needed…
ET Jaynes has a book "Probability Theory: The Logic of Science". It's a nice book, and I was wondering if you had any thoughts on it.
Do you disagree with ET Jaynes then?
They won't, but MoS_2 very well could be.
Superconductivity in TBG was originally sold as "unconventional". This article reaffirms that claim by showing how it cannot be a BCS superconductor, and more. Very interesting. It's worth reiterating that while…
The other problem with this approach is that it is limited to 50% efficiency long-term. They claim "up to 90%", but it is only 90% efficient immediately after switching directions. The efficiency then drops to 0% before…
Matt Yankowitz' "Tuning superconductivity in magic-angle graphene" shows how hydrostatic pressure affects TBG magic.
I was measuring a delicate electronic device at MagLab in Tallahassee. They warned me that the best data would be had at night, because of reduced noise from a nearby radio station. Precisely at 8 PM every night my data…
Particle physics does not include that. There is no evidence that superconductivity requires any physics outside of the standard model.
You can probe different areas of the same device by adding many electrical probes, usually in a geometry called a Hall bar. In the old days of TBG, the different regions of the same device would do wildly different…
The mechanical tearing imparts the strain. Probably. Nobody really knows that for sure. These days, common practice is to cut the graphene with an AFM or laser prior to stacking.

Lovely article. > Creating a working device typically takes them dozens of tries. And even then, each device behaves differently, so specific experiments are almost impossible to repeat. This is frustrating. You can…
The article is from 2016, before she started her YouTube channel.
I'm probably misreading this, but I see "In this study, age ≥65 years, immunosuppression, diabetes, and chronic kidney, cardiac, pulmonary, neurologic, and liver disease were associated with higher odds for severe…
I have comcast internet with my own modem/router. Comcast will not give me a static IP unless I use their rental modem/router, which costs quite a bit monthly. I use ddns to work around this issue, and it mostly works…
It's sad that a great scientist got caught up in politics here. I suspect that if he had received money from any other country then he would have received a mere slap on the wrist. Of course what he did was mega illegal…
I felt like this book was incredibly clever, but at times it felt like the pacing was infuriatingly slow. Especially near the start, it feels like there are too many chapters of world building per chapter of story.…
> The new particle contains two charm quarks and an up and a down antiquark. Several tetraquarks have been discovered in recent years (including one with two charm quarks and two charm antiquarks), but this is the first…
I used to play a real-time version of this called Kung-Fu Chess. Each piece takes time to move to its destination, and when it arrives, a timer ticks down before that specific piece can be moved again. Very fun game.…
I don't understand what you are saying. The parent comment said that quantum allows a few types of operations to get faster, and your response was "No," followed by a specific algorithm that is faster. Where do you…
Nice article! Many of the cool excitonic properties that he describes were recently (last 10 years ish) seen in a class of materials known as TMDCs: https://en.wikipedia.org/wiki/Transition_metal_dichalcogenid...…
I personally think that the Hofstadter butterfly stuff is absolutely gorgeous, and it was a large part of why I started working on 2D materials in the first place. https://en.wikipedia.org/wiki/Hofstadter%27s_butterfly…
I think CVD graphene (grown, production-scale stuff) has gotten to decent quality these days. There's much more to these devices than graphene, however. You may have noticed that literally every experimental paper on…
