Real-time observation of Cooper pair splitting showing strong non-local correlations
Antti Ranni, Fredrik Brange, Elsa T. Mannila +2
Controlled generation and detection of quantum entanglement between spatially separated particles constitute an essential prerequisite both for testing the foundations of quantum m…
Determination of dynamical quantum phase transitions in strongly correlated many-body systems using Loschmidt cumulants
Sebastiano Peotta, Fredrik Brange, Aydin Deger +2
Dynamical phase transitions extend the notion of criticality to non-stationary settings and are characterized by sudden changes in the macroscopic properties of time-evolving quant…
Lee-Yang theory, high cumulants, and large-deviation statistics of the magnetization in the Ising model
Aydin Deger, Fredrik Brange, Christian Flindt
We investigate the Ising model in one, two, and three dimensions using a cumulant method that allows us to determine the Lee-Yang zeros from the magnetization fluctuations in small…
Controlled emission time statistics of a dynamic single-electron transistor
Fredrik Brange, Adrian Schmidt, Johannes C. Bayer +3
Quantum technologies involving qubit measurements based on electronic interferometers rely critically on accurate single-particle emission. However, achieving precisely timed opera…
Noise and full counting statistics of a Cooper pair splitter
Nicklas Walldorf, Fredrik Brange, Ciprian Padurariu +1
We investigate theoretically the noise and the full counting statistics of electrons that are emitted from a superconductor into two spatially separated quantum dots by the splitti…
