Periodic Reporting for period 2 - QuStA (Quantum State Assembler)
Reporting period: 2018-10-01 to 2020-03-31
To test what is exactly the mechanism behind this phase transition, the researchers started to look into the correlations that might be responsible, for which they had to devise a new method to detect each and every single particle. To test this method, they used it on a system of noninteracting fermionic atoms, which obey the Pauli principle also known from chemistry. As of these particles only one can occupy a quantum state at a time. This is how they form what is called a Pauli crystal, even though there is literally no interaction between them. QuStA could for the first time observe such a crystal.
