Ultra-low-temperature cooling is essential in many applications, such as superconductivity, quantum computing, and fundamental research like Bose-Einstein condensation. Several techniques are used to reach low temperatures, such as thermodynamic cycles, laser cooling, and dilution refrigerators. This seminar will discuss the working principles of some techniques, their limitations, and the most used techniques in certain applications.

Ion beam analysis is a highly sensitive analytical method to determine the composition of a sample. It can give information about the concentration of elements in a sample and the depth at which they are located. This seminar will give an overview of RBS and MEIS, as well as experimental data acquired with these techniques to compare them.

The quantum measurement problem is a problem at the foundations of quantum mechanics and is considered to be one of the most important open problems in physics to this day. Unlike classical mechanics where we have a deterministic equation like Newton’s equation and a deterministic outcome at the point of measurement, in quantum mechanics the Schr¨odinger equation is deterministic in the sense of being able to predict the evolution of the wavefunction over time given the initial state of the system, but there is a discrepancy at the time of measurement that instead of having the different probabilities predicted by the theory, these probabilities collapse into one random outcome at the point of measurement which is known as the collapse of the wavefunction. This seminar will talk about the different interpretations of quantum physics and the experiments related to them 

 

All faculty, researchers and students are invited to attend.
