New Universality Class Describes Vicsek’s Flocking Phase in Physical Dimensions Open
The Vicsek simulation model of flocking together with its theoretical treatment by Toner and Tu in 1995 were two foundational cornerstones of active matter physics. However, despite the field’s tremendous progress, the actual universality …
A new universality class describes Vicsek's flocking phase in physical dimensions Open

Can exact scaling exponents be obtained using the renormalization group? Affirmative evidence from incompressible polar active fluids Open
In active matter systems, non-Gaussian, exact scaling exponents have been claimed in a range of systems using perturbative renormalization group (RG) methods. This is unusual compared to equilibrium systems where non-Gaussian exponents can…
Critical phenomena in compressible polar active fluids: Dynamical and functional renormalization group studies Open
Active matter is not only relevant to living matter and diverse nonequilibrium systems, but also constitutes a fertile ground for novel physics. Indeed, dynamic renormalization group (DRG) analyses have uncovered many new universality clas…

Physical properties of the massive Schwinger model from the nonperturbative functional renormalization group Open
We investigate the massive Schwinger model in $d=1+1$ dimensions using bosonization and the nonperturbative functional renormalization group. In agreement with previous studies we find that the phase transition, driven by a change of the r…

From Text to Data Open
This article outlines our practical approach to digitizing historical text sources via Optical Character Recognition (OCR) for subsequent Natural Language Processing (NLP) and corpus analysis. For this purpose we developed two processing p…
