How can we calculate entropy produced by plastic deformation in this example?
Suppose we have a massless spring of spring constant $k$ attached to a mass $m$ at equilibrium position $x_{0}$ at temperature $T$. The mass may oscillate in one dimension only for simplicity. We ...

Could a transparent frequency-altering material be possible?
I would imagine a material that is transparent but a electromagnetic wave going out will have a lower frequency than when going in (and maintaining it's direction). You could build glasses to see UV-...

Structure factor correct calculation
I have a set of 2D points and wish to test it for hyperuniformity.
As I've learned from papers, the good idea is to calculate structure factor $S(\mathbf {q})$ and test it for
$$\lim _{\mathbf {q} \to ...
