Universal critical behavior in ideal Bose-Einstein condensation
Arturo Camacho-Guardian, Leon Kleebank, Frank Vewinger +4
Ideal Bose-Einstein condensation (BEC) remains a paradigmatic example of a continuous phase transition and a cornerstone for understanding quantum degenerate bosonic matter. We dem…
Dimensional Crossover in a Quantum Gas of Light
Kirankumar Karkihalli Umesh, Julian Schulz, Julian Schmitt +3
The dimensionality of a system profoundly influences its physical behaviour, leading to the emergence of different states of matter in many-body quantum systems. In lower dimension…
Observation of critical scaling in the Bose gas universality class
Leon Kleebank, Frank Vewinger, Arturo Camacho-Guardian +4
Critical exponents characterize the divergent scaling of thermodynamic quantities near phase transitions and allow for the classification of physical systems into universality clas…
Thermodynamics and State Preparation in a Two-State System of Light
Christian Kurtscheid, Andreas Redmann, Frank Vewinger +2
The coupling of two-level quantum systems to the thermal environment is a fundamental problem, with applications ranging from qubit state preparation to spin models. However, for t…
Time-periodic driving of a bath-coupled open quantum gas of light
Andris Erglis, Alexander Sazhin, Frank Vewinger +3
We study the frequency-resolved density response of a photon Bose-Einstein condensate coupled to a bath of dye molecules by time-periodic driving. By monitoring the photon number d…
