Does the structure constant of Yang-Mills field change sign under time reversal?

The time reversal of Abelian (electromagnetic) field strength is pretty straight forward. The electric field $F_{0i}$ is even under time reversion. The magnetic field $F_{ij}$ is odd under...

Non-orthogonal transformations of the inertia tensor

The inertia tensor for a point is given by$$ I_{ij} = m(delta_{ij} ||x||^2-x_i x_j)$$where $m$ is the mass of the point and $x_{i}$ are the...

Different results for torque in inertial and non-inertial frames of reference

I have a right handed coordinate system with origin O. On the plane yz there's a triangular-shaped plate with sides lying on the axes, both of length a. The plate...

If a polarized light wave is indistinguishable from its original self after being flipped 180°, why doesn't a photon have a spin of two?

The spin of a photon has a counterpart in classical physics, it's polarization, right? And if you spin a polarized light wave by 180°, (or pi radians), it is now...

Can we define the concept of temperature for a system in non-equilibrium steady state?

I would like to define the temperature for a system in a non-equilibrium steady-state. The standard textbooks show that the temperature is estimated by equating the internal energy of the...

How to model RNA-DNA and DNA-DNA binding as a “string matching" problem in statistical physics?

I am trying to model the binding of a guide-RNA molecule with a target-DNA strand as it occurs before the CRISPR-Cas9 protein cuts the DNA. Both the RNA (...
