Einstein-Cartan Gravity: This looks real cool! It seems to solve a few problems, though the wiki page seems a little biased, perhaps? It combines classical spin with GR through affine torsion. In doing so it makes finite extent fermions and produces the correct intrinsic-orbital coupling. http://en.wikipedia.org/wiki/Einstein%E2%80%93Cartan_theory

Gravitomagnetic charge: From wiki, it looks like it’s just mass density…which is unexciting. Gravitomagnetism is cute though! Important “While Maxwell’s equations are invariant under Lorentz transformations, the GEM equations were not” also crazy “The analogy and equations differing only by some small factors were first published in 1893, before general relativity, by Oliver Heaviside as a separate theory expanding Newton’s law.[1]” Wiki
Relevant paper here: Acceleration of particles by black hole with gravitomagnetic charge immersed in magnetic field. It is worth noting from the abstract:
“The presence of the external magnetic field decreases the innermost stable circular orbits (ISCO) radii of charged particles.”

Stückelberg Portal:
The Stückelberg mechanism allows for U(1) symmetries to eat Axion-Like-Particles (ALPs) that arise in extensions of the SM. If you have couplings between Abelian fields and associated ALPs you need cancellations to occur or else there are anomalies in the low energy theory. There are several theories of DM that involve a totally different sector of particle physics and these particles would likely have U(1) connections. This is something I should look into more since it reminds me of the little I know about Kinetic Mixing. More: here and another similarly named paper.

Woods-Saxon interaction:
Pertaining to the Woods-Saxon potential, a radial potential of a slightly ugly form relevant in shell models of nuclear physics.
Bethe-Salpeter Equation:
Bound state equation for two-body particles, relativistically covariant….Nambu found it first, fun fact. Relevant to calculation things like positronium properties, excitons, quark-antiquark bound-states. Large mass difference? Treat light particle as a Dirac particle in the potential of the heavy particle. Derived with the poles of the S-matrix and related to the Green’s function and scattering processes.

Next is “A simplified differential equations approach for Master Integrals.”

Snowmass Papers I need to read:
Chapter 1, Chapter 6, Chapter 3,

Chromomagnetic Vortex:
This is going to be a mess. In some “popular” models the QCD vacuum is composed of entangled ‘chromomagnetic vortices’ which divide the vacuum into domain-like structures [wording stolen from paper sourced below]. The domains are so named because all vortices in a domain are oriented in space and in color, like how magnetic domains are or ordered by spin. Large scale randomization allows for Lorentz and color symmetries to be recovered in the IR regime [how?]. It’s called a ‘spaghetti vacuum’ for unclear reasons…there’s nothing stringy about these domains from the intro…Confinement comes from the infinite free energy of an isolated quark, this energy comes from the random phase variation across domains and the averaging over this phase.
The intro to the relevant paper is awesome and I’ll definitely read the rest to get to the spaghetti part later 🙂 Paper’s called: Fermion zero modes in a chromomagnetic vortex lattice 8 pages of awesome from what I can see…I’ll get around to Zero Mode Fermions later.

ST: 1 hour in, I think I’ll break for a little then continue for another hour. The progress made is almost all computational and I should really work on something more interesting for a bit.
X11 is mostly conquered for Cygwin using:

I’ve also reached some conclusions about languages. I’m going to start Scheme then move into Clojure after I get into SICP some.

HEP:
CalcHEP is *definitely* broken on this machine…I’ll need to do something about that later. Luckily the X11 support makes it visible when it breaks?
Organizing papers/reference material. References for original paper all together…I’ll look for a few more now!
I need to look at this… http://arxiv.org/find/all/1/all:+CalcHEP/0/1/0/all/0/1
I want to go to CKM 2014…
Photran now installed via Eclipse

ST:
UGHHHasfjkahsdf 1.5 hours sunk…another .5 up trying to tie up some mess. UGH all that work and now mathematica mess.
A couple weeks back I put git on my list of things to learn more seriously…I’m beginning to regret not having done that sooner. Long story short Kranc wasn’t working and I had to fix some files by hand -.-‘
UGHH akjjhfjawf I reduced precision and now suddenly the code works ;-; What the actual ffffff alkjfhlksfhlsf 3 hours in today and I guess I got a thing or two productive done 😐 meh

HEP:
CF calculations are not working out well…I have worked out quite a bit, though. I think I’ll put about ~1 hr more into it later tonight to get up to about 4 hours. I think I may have found the problem but I need a working copy of X11 with Cygwin or another machine in order to check -.-‘ …not fun, not fun at all.

Math?:

Other:
Human After All is a decent album…too lazy/unknowledgable to critically expand on this. Read some, that was nice too.

Arxiv:
This is only going to be a list of the titles I read and found of interest from the past month or so. Tomorrow I’ll start cutting by abstract. After that introductions / conclusions. Hopefully I’ll get down to the interesting stuff by Friday afternoon. The image below is, clearly, just Hep-Ph. I’m also combing through Gr-Qc as well.

Progressing through the new year...I'm a bit behind.

Day starts at ~11 -.- oops. Free food is good, though!

ST:
Plan for progress first. First thing is to finish reading the paper’s Laguna sent me today. Next, evaluate some recent runs. Draft new potentials. I need to know [from thin wall approx] how much energy to pump into the bubble. Once I get some things running, computational stuff. Arxiv should be checked at some point and I should review the papers in my queue.
Mendeley+Dropbox is on my agenda, ReadCube will be up next if Mendeley is bad. Invite 4 dropbox to get up to ~5 gigs

HEP:
Nothing has really changed in the highest energy neutrino research…woo?
Organizing documents to better determine where to spend time and solve problems for later.

Of note:

Also, this is cute: http://en.wikipedia.org/wiki/Crystal_field_theory

Return to Complex Analysis on Tuesday?

1/25/2014

Oh my Saturday is mostly gone D:

6-8 pm mostly focused on organizing CLC this semester.

8-10 pm dinner and shopping for stuff

10-11 Mathy stuff [little bit of dance stuff snuck in]

An odd polynomial has at least one real root, an even one may not though. . .sad that it had never occurred to me in those terms before .-. read: “19. Complex numbers” from Predrag’s link.
Looking at HW9. 3a was silly :3 onto 3b…also not bad, reminded me that I need complex algebra practice, though! 3c…looks fine? Except the twist they talk about…

11-12 Daily show :3 and some integration bee planning

Yesterday:

Starting way late today 6:30-7:30 looking for music 🙂 Downloading some stuff then looking for ballroom music :O

ST:
More people need to use ScholarPedia
http://www.scholarpedia.org/article/Cosmological_constant
and people should see this, too:

+.5 on Coleman De Lucca. Interesting ending
1hr in, GDB day? Maybe? Waiting on responses, still NaN-ing.

The possibility that we are living in a false vacuum has never been a cheering one to contemplate. Vacuum decay is the ultimate ecological catastrophe; in the new vacuum there are new constants of nature; after vacuum decay, not only is life as we know it impossible, so is chemistry as we know it. However, one could always draw stoic comfort from the possibility that perhaps in the course of time the new vacuum would sustain, if not life as we know it, at least some structures capable of knowing joy. This possibility has now been eliminated.

Learning some pipe…

2>/dev/null is cute for redirecting to a blackhole~
I should look into using xargs more, limiting the number of things it passes is nice. -n etc Also, I could use stdin for something, probably?

HEP:
Algebra is a bitch…found what I thought was a missing term…turns out it was just a nice cancellation -.-‘

Assumption: -uel = -tg and -uel=-tu..check this. Also need to check power on alpha when I put the Ac in properly.

Fixed a sign error in C1 in Mathetmatica that was pretty blatant…then fixed it universally.

Done with NLO elastic part, will do elastic part next ~4:45 (1.5 hours down)

5-6:30 Planning for the contest

6:30-9:30…waste 😦
