Ab initio Complex Langevin computation of the roton gap for a dipolar Bose condensate
Philipp Heinen, Wyatt Kirkby, Lauriane Chomaz +1
We compute from first principles the dispersion relation of a dipolar Bose gas of erbium atoms close to the roton instability by employing the Complex Langevin (CL) algorith…
Simulation of ultracold Bose gases with the complex Langevin method
Philipp Heinen
This PhD thesis gives a comprehensive treatment of ab initio lattice Monte Carlo simulations of ultracold Bose gases by means of the complex Langevin algorithm. Since the field-the…
Universal Dynamics at the Lowest Temperatures
Ido Siovitz, Philipp Heinen, Niklas Rasch +5
High-performance graphical processing units (GPU) are used for the repeated parallelised propagation of non-linear partial differential equations on large spatio-temporal grids. Th…
Simulating the Berezinskii-Kosterlitz-Thouless Transition with Complex Langevin
Philipp Heinen, Thomas Gasenzer
Numerical simulations of the full quantum properties of interacting many-body systems by means of field-theoretic Monte-Carlo techniques are often limited due to a sign problem. He…
Non-thermal fixed points of universal sine-Gordon coarsening dynamics
Philipp Heinen, Aleksandr N. Mikheev, Christian-Marcel Schmied +1
We examine coarsening of field-excitation patterns of the sine-Gordon (SG) model, in two and three spatial dimensions, identifying it as universal dynamics near non-thermal fixed p…
Anomalous scaling at non-thermal fixed points of the sine-Gordon model
Philipp Heinen, Aleksandr N. Mikheev, Thomas Gasenzer
We extend the theory of non-thermal fixed points to the case of anomalously slow universal scaling dynamics according to the sine-Gordon model. This entails the derivation of a kin…
