Another Lesson from the Coupled Oscillator: Fano Lineshape

Every once in a while, I read a paper that exhibits a rather odd spectral signature. This odd spectral signature is asymmetric and looks something like this (taken from Wikipedia): 446 more words

Lessons from the Coupled Oscillator

In studying solid state physics, one of the first problems encountered is that of phonons. In the usual textbooks (such as Ashcroft and Mermin or Kittel), the physics is buried underneath formalism. 324 more words


The Quantum-Mechanical Gas Law

In my previous posts, it was mentioned repeatedly that the kinetic theory of gases is not quite correct: the experimentally measured values of the so-called… 2,150 more words


The Bathroom Scale in Orbit

When being on the International Space Station (ISS), you cannot just go grocery shopping if the food is running out – the reasons for that are mainly of logistical nature, logically. 930 more words


The harmony of being at the minimum

I am always amazed by the idea of being at the minimum. Because every physical system near the minimum is an harmonic oscillator, and we love harmonic oscillator ! 296 more words
