If i calculate band structure of Sr2Nb2O7 instead of SrNbO3.5 with Quantum Espresso, is same result that i get?

i actually want to calculate band structure of SrNbO3.5 with quantum espresso, but i have some trouble with its atomic position. my colleague advice me to use Sr2Nb2O7, but i doubt with the result...

1. If I can quantize the atom using this hyperbolic spiral and classical physics, could nature do the same?

If we map as a continuous motion an ionising electron (beginning its journey at n=1) in an H atom, a specific hyperbolic spiral appears (see animation). When we solve this spiral formula, we find...

How are iso-frequency contours plotted?

Let's say we have a standard, regular hexagonal honeycomb with a 3-arm primitive unit cell (something like the figure attached; the figure is only representative and not drawn to scale). The...

Could dyes amplify the spectrum of light to a specific wavelength?

I am interested to know the behavior of dyes toward light. Specifically, Blue dyes re-emit the spectrum, especially from the green zone (known as principal in LED lamps, and blue dyes are known...

Is the zero-zero component of the metric tensor equal to 1 for accelerating reference frames?

Consider the case of negligible gravity but there is an accelerating reference frame. Its origin traces out a trajectory, or world line, seen in some inertial reference frame. The Lorentz metric...

Why can't I detect the plasmon resonance angle with water?

I am trying to measure the plasmon resonance angle of gold film and pure water using the Kretschmann configuration and a 633nm laser. Without flowing water over the gold, I can detect a clear...
