An optical n-body gravitational lens analogy
Markus Selmke
Raised menisci around small discs positioned to pull up a water-air interface provide a well controllable experimental setup capable of reproducing much of the rich phenomenology o…
Bubble optics
Markus Selmke
Starting from a peculiar image observed below a bubble floating at a water-air interface, the article analyzes several optical properties of these special types of refracting objec…
Revisiting the round bottom flask rainbow experiment
Markus Selmke, Sarah Selmke
A popular demonstration experiment in optics uses a round-bottom flask filled with water to project a circular rainbow on a screen with a hole through which the flask is illuminate…
Artificial circumzenithal and circumhorizontal arcs
Markus Selmke, Sarah Selmke
We revisit a water glass experiment often used to demonstrate a rainbow. On a closer look, it also turns out to be a rather close analogy of a different kind of atmospheric optics…
The physics of the photothermal detection of single absorbing nano-objects: A review
Markus Selmke, Frank Cichos
The literature on the theory of the photothermal imaging of single nano objects is reviewed. Several models have been devised to describe the signals magnitude, phase and shape in…
