Chirality Definition and 66 Threads

[SIZE="4"]Hi. I need some information about chirality and Helicity basic information it's application in Dirac equation and quantum field any notes or presentation good reference I'm still Beginner in these subject

Homework Statement How are my hands not constitutional isomers? The Attempt at a Solution I read this in a book today (Organic Chemistry for Dummies - good book actually), and I was covering chirality. Now, I am a bit shaky on it and need to go over it, but I got stuck on this for...

Is is right to say that the two dirac cones are described by two bi-spinors of different chirality?... Is it right to say that each of the dirac cones contains quasi-particles of different helicity (electrons of positive elicity and of holes negative elicity for one dirac cone and the...

As far as I remember, I heard from someone that the matrix \gamma^5=i\gamma^0\gamma^1\gamma^2\gamma^3 also known as the chirality operator in 3+1 dimension is not defined in odd dimensions. I do not understand why that should be the case. Suppose I am in the 4+1 dimension and I choose one...

What is the difference between chirality and helicity? I know, that helicity shows the handedness of the particle. For example, we have a right-handed electron if its spin is aligned in the direction of its propagation. The concept of chirality is a bit similar to that of helicity, but something...

I really don't understand any of this. I already know the answers to these, but I don't know why they are chiral or achiral. Any help is appreciated. http://i57.photobucket.com/albums/g231/Paylardo/Chriality.jpg The "HO" on the far left was cut off. It is just another hydroxyl group.

One difference between GR and LQG is that LQG is chiral, whereas GR is not. In order to break the electroweak symmetry, a higgs field needs to be introduced by hand. Einstein's understanding of inertia implies a strong EP as gravitational mass and inertia are identical, while a higgs...

My difficultly is in trying to visualize what chirality physically means. In solid state system, people usually ascribed electron of one chirality to be electron in the conduction band while the opposite chirality belongs to an unoccupied state (hole) in the valence band. Can I then say the...

1) How do one describe particles with chirality? Dirac and Weyl equation? 2) Are particles of different chirality interacts? 3) Does electron have chirality?

What results in Chirality? And what is the physical implication of chirality in Dirac equation?

When it was in the news about neutrinos having mass, I wondered what that meant about left-handed only-ness. You could catch up to one and pass it, or slow one down. More recently, I read that the helicity of the neutrino is invariant but the chirality can still change. What is the...

I had to answer true or false for the following five questions. If they were false, I had to explain why. 1. In some cases, constitutional isomers are chiral. TRUE 2. Every chiral compound has a diastereomer. TRUE 3. Some diastereomers have mirror-image relationship. FALSE...

I just read a book by Davies and Brown entitled "_Superstrings:_A_Theory_of_Everything_?" They dismiss 11D theory as having a fatal flaw: -"A distinctive element of the weak interaction is that it breaks left-right mirror symmetry. This implies that elementary particles must be endowed with a...

I'm trying to get my head around part of my course in string theory from last term, specifically the nature of Neveu-Schwarz (NS) and Ramond (R) sectors. When constructing states in NS you start with a groundstate |0,p\rangle and use the bosonic and fermionic operators \alpha_{-n}^{i} and...
