Chiral non-Abelian domain walls in dense QCD
In this paper, we study chiral non-Abelian domain walls in a phase of unconventional vacua of dense QCD. The phase is characterized by asymmetric vacuum-expectation values (VEVs), for example with the left scalar field, corresponding to the left quark-quark condensate, having a nonvanishing VEV and the right field having a vanishing one. The domain wall soliton interpolates between this vacuum and another where the left and right scalar fields switch roles. We contemplate that such vacua could …

Turing complete Navier-Stokes steady states via cosymplectic geometry
In this article, we construct stationary solutions to the Navier-Stokes equations on certain Riemannian $3$-manifolds that exhibit Turing completeness, in the sense that they are capable of performing universal computation. This universality arises on manifolds admitting nonvanishing harmonic 1-forms, thus showing that computational universality is not obstructed by viscosity, provided the underlying geometry satisfies a mild cohomological condition. The proof makes use of a correspondence betw…

Dense matter in a holographic hard-wall model of QCD
A deeper understanding of QCD matter at strong coupling remains challenging due to its non-perturbative nature. To this end, we study a two-flavor holographic hard-wall model to investigate the properties of QCD at finite-density and zero temperature with a nonvanishing quark mass. A dense matter phase is described by a classical solution of the equations of motion in a homogeneous Ansatz. We apply holographic renormalization to formulate the holographic dictionary that relates UV boundary data…

Florian Kohfeldt hat Darmstadt 98 übernommen – seine größte Aufgabe bislang? Der Ex-Bremer bringt Erfahrung und das Versprechen von 'dominantem Ballbesitzfußball'. Ob die Lilien nach der etwas verkorksten Rückrunde tatsächlich aufblühen, ist die Frage. Der Verein setzt auf Neuanfang, aber Wunsch und Wirklichkeit liegen selten auf demselben Rasen.

Laser micromachining of arbitrarily complex and overhang-free SiN nanomechanical resonators
Research on silicon nitride (SiN) nanomechanical resonators produces an exceptionally rich variety of resonator geometries, for which there is currently no available rapid prototyping solution. Experimental advances in nanobeam, trampoline, phononic bandgap, and soft-clamping structures all rely on conventional nanofabrication involving e-beam or photolithography, followed by various etching steps. These techniques are typically time-consuming, relatively inflexible, and often result in spuriou…
