Is there a method like the described below in virology?

My specialty is quantum physics but because of the pandemium I was interested in physical methods applied to virology. Today's physics is at nanolevel manufacturing so I suppose it can solve...

Does the energy of the photon change in Beth 1936 experiment?

When a left (right) polarized photon reflects from a birefringent plate it changes its polarization to right (left). The internal orbital momentum of the photon thus changes by 2hbar. The orbital...

Is it possible to recombine an electron with the ion of an atom and receive the atom in the basic (lowest) energy level in around 90 % of the cases?

What are the conditions to achieve this? Is it sufficient that the relative velocity between ion and electron and hence the subsequent kinetic energy is below excitation energy to next energy...

Is diffraction of a particle a case of an action without a cause breaking by way of the first law of Newton?

Suppose a single particle (photon or electron) passes through a slit. It doesn't interact with anything. Nevertheless it changes direction because of diffraction of it's wave function. But the...

Double slit with a clock

We have the simple arrangement of the double slit, but with the addition of a precise clock. The screen is also substituted by a CCD camera, so one can check when there is an event (hitting of the...

Holography question (interference visibility)

For the double slit interference (Thomas Young 1901) the distance between the peaks b on the screen is derived by the well known formula b=H.l /D where H is the distance ftom the slits to the...
