I genuinely don’t understand how people feel so at ease to take away artistic freedom and creativity from the people who have it and practice it, just to make themselves feel better for having art/owning art for free
Lovely to meet someone physically and getting to know the person who has been "following you".
Thank you Sarthak for taking time out to discuss and interact after the talk. I am enjoying @tvmiiser campus and my interactions with students and faculty here. I wish you the best!
do y’all know any good places to organize a group project’s research?
currently trying to do a project where a few of us are contributing on different ends that have to be integrated later on.
any platform, place, app you could recommend?
heyy
i’m here after a while again but i think i might use this again now that i’m finally stabler than the past few years. I’m definitely trying to reach out to research twitter back again and have good discussions.
anyways hii i’m a theoretical physics student! hmu
Dec 8 - EFT / model building and the anomalous perihelion of mercury
https://t.co/zlszMKwDH2
Wells explores how a model building / EFT approach to explaining Mercury's orbit would have worked. He introduces 3 ideas that all can work, and are realized in GR in different gauges.
Dec 9 - Axion-electron coupling limit from 47 Tucanae
https://t.co/uSoXeb0SnA
From white dwarf cooling in this globular cluster, Hansen et al. bound the axion coupling g_ae < 8.4E-14. This excludes the hint of axion cooling seen in previous studies (eg https://t.co/WY5nJX8Lpf)
Dec 10 - Detectors and Rindler Particles
https://t.co/NOou7WdlY5
Unruh and Wald give a fantastically clear explanation of why accelerating observers see a thermal spectrum of particles: the particles are created from the energy you put into the detector to accelerate it.
Dec 7 - The Age of the Universe
https://t.co/E3JsVx4Kph
Combining data from CBI, DASI, BOOMERANG ++, Seivers et al. measure the age to be 13.7 +/- 0.2 billion years in near perfect agreement the modern value. This is when cosmology becomes a precision subject.
Dec 6 - Coherent Phase Argument for Inflation
https://t.co/5C6gLsXWFj
The horizon problem in the era of precision CMB is better understood in terms of the fact that all sound waves have the same phase. Dodelson provides a simple and powerful explanation of this modern argument.
This is just a paper I have always enjoyed reading for the clarity of the physics of micro-causality and its proxies in terms of analytic properties of correlators. I have always felt there were nice ideas that they articulated in a way that I haven't encountered elsewhere.
Dec 5 - Microcausality in Curved Space-Time
https://t.co/DVIF0m6fhb
Causality is a central principle in physics, but how it manifests itself in quantum mechanical observables can be opaque. This paper provides a careful treatment of (some of) what it does and does not imply.
This paper is has 10 citations, yet it connects NR EFT in curved space with relativistic QFT, and inflation with holography. They show explicitly how to go between QFT and the physics in curved / dynamical backgrounds. There are 100+ cite papers on this subject that do much less
