Would a course in condensed matter physics be useful for stuff like neutron stars?

Yeah, probably. I think principles of condensed matter are used in studying the internal structure of neutron stars.

when I am anxious, time passes slower than I imagine. In the past two weeks, when it was Wednesday, I considered it's Friday the next day. Then when I checked calendar, finding it's only Thursday the next day, I felt gratified because I felt like I earned an extra day to do things.

@CaptainBohemian Good thing that it doesn't pass faster than you imagine! ;)

"most of this material cannot be assimilated by reading books. You need to take courses following an appropriate Master program and pass exams."

Well so much for that

The notion of oneness is so out of date

and these pseudoscientists sure never tired to paste the word "quantum" in anything they can find

Which one is the good Lee on manifolds

There's like 4 books by a Lee on manifolds

ACuriousMind

12:20 PM

I think it depends on what sort of manifolds you're interested in? E.g. one is mainly about smooth manifolds, iirc

Mats Granvik

$$f(t)=\frac{\text{sgn}
(Z(t))\left|\sum\limits_{n=1}^{n=k} \frac{1}{n} \zeta(1/2+i \cdot t)\sum\limits_{d|n}\frac{\mu(d)}{d^{(1/2+i \cdot t-1)}}\right|}{g(t)+H_{\text{k}}}$$

$$g(t)=\frac{\partial \vartheta (t)}{\partial t}$$

Slereah

@ACuriousMind Spacetimes, obviously

Which one had the tangent bundle at chapter 6

I remember that part

12:56 PM

hello

there is a formula that I don't understand

here is the photo

and here is the formula phoro

it is supposed to be the formula of the moment of the rotational joint

but I have no idea where it's come from

there are a bunch of 1/2 and negatives and positives that I don't get

the formula that I know for moment is F * (distance) which in here is W*L

parvin

1:20 PM

I found the answer

@Slereah yikes

Slereah

odd stance considering he probably didn't learn string theory in school himself

coniferous_smellerULPBG-W8ZgjR

does anyone knows the difference between a thermopile and a thermoelectric generator?

google returns a blank stares at me when I ask him the question

bolbteppa

Was the SM and QFT on your transcript

I guess it's no loss

The York thing looks more up your alley as well

The 19-20 list is already filling up edpif.org/en/recrutement/prop.php

coniferous_smellerULPBG-W8ZgjR

nvm I got it, thanks

bolbteppa

There are like 14 gravity related ones in the 18-19 list, some with a green light, but you could check those names personal pages to see if there are any comments on applying

'Le premier volet de la thèse concerne les théories alternatives à la relativité générale motivées par le souhait d'interpréter les observations cosmologiques, conduisant dans le cadre du modèle standard de la cosmologie à supposer l'existence de matière ou d'énergie noire, d'une façon différente: via des modifications à grande distance de l'interaction gravitationnelle.

Le deuxième volet de cette thèse concerne la théorie des ondes gravitationnelles, motivée par les détections récentes LIGO/Virgo. L'étudiant s'insèrera dans notre programme du calcul du champ d'ondes gravitationnelles émis par un système de deux objets compacts (étoiles à neutrons ou trous noirs) à l'approximation 4PN de la relativité générale.'

Thx man

Gonna send a bunch more applications tomorrow

Man York isn't nearby

"The mathematics involved in my work ranges across functional analysis, Lorentzian geometry and category theory."

Noooooo

bolbteppa

Did he say that

Doing a phd pretty much usually involves going to a new country/state/region, just a harsh fact of this whole thing one doesn't even question hah

Slereah

yeah but I've got this real estate tied up right here :V

Which is annoying

bolbteppa

I'd say that French list will get pretty big soon and you have the 2018-19 list as well

Slereah

4:05 PM

yeah I am keeping an eye on it

Gotta do this before the Brexit!

bolbteppa

ipht.fr/en/Phocea-SPhT/ast_visu_spht.php?id_ast=267 as well

Slereah

Already got that one

Applied to "Non-Unitary Quantum Field Theory" so far

So far no answer!

bolbteppa

Ah no stay away from that hah

haha

Slereah

Why

bolbteppa

Let me read it

' The Advanced ERC grant project NuQFT focusses on the understanding of the physical and mathematical aspects of non-unitary quantum field theories in 1+1 dimensions. Subtopics of interest include Logarithmic conformal field theory, sigma models on supergroups, Liouville theory, the Bethe-ansatz for super spin chains, lattice models for the Integer quantum Hall plateau transition (and other classes of topological insulators), and statistical loop models.'

It's a real integrability/cft project

Slereah

4:08 PM

Not too bad

If I only applied to GR thesis I wouldn't go very far unfortunately

I mean so far 100% just answered "no"

bolbteppa

Yeah, all you have to do is get 1 though hah

Slereah

yeah

Hence the broad net

I mean if in the end

I have two to chose from

Then I can be picky

Q: A possibility of the theoretical derivation of Pauli's Exclusion Principle

Pauli's exclusion principle tells us (in an informal language) that each and every electron in an atom is unique. When I searched for a derivation , I got nil everywhere (even the wiki site says only that it's equivalent to anti-symmetry of wave functions with respect to exchange). However the c...

Should we merge this duplicate?

Slereah

Also saw Lyon yeah

Plus I got friends in Lyon

Which is nice

Q: What does a photon emitted by an atom "look" like?

Consider the emission of a photon when an atom decays from an excited state to its ground state. In most cases, this emitted photon is depicted as a small wave-packet being expelled by the atom in a well-defined direction. However, quantum optics tell us that photons are essentially associated wi...

isn't it nice that a question like this can exist for a substantial length of time without attracting crackpot answers?

@JohnRennie there's a high likelihood that I'll be in Chester in mid-August of next year. I'll ping you closer to the date to see if you're up for a pint.

(drop me an email at my easy-to-find address if you'd rather I contact you elsewhere.)
