Simulation of thin film flows with a moving mesh mixed finite element method

Hong Zhang, Paul A Zegeling

We present an efficient mixed finite element method to solve the fourth-order thin film flow equations using moving mesh refinement. The moving mesh strategy is based on harmonic m…

Density Distribution of a Bose-Einstein Condensate of Photons in a Dye-Filled Microcavity

S. Greveling, K. L. Perrier, D. van Oosten

The achievement of Bose-Einstein condensation of photons (phBEC) in a dye-filled microcavity has led to a renewed interest in the density distribution of the ideal Bose gas in a tw…

Homoclinic saddle to saddle-focus transitions in 4D systems

Manu Kalia, Yuri A. Kuznetsov, Hil G. E. Meijer

A saddle to saddle-focus homoclinic transition when the stable leading eigenspace is 3-dimensional (called the 3DL bifurcation) is analyzed. Here a pair of complex eigenvalues and…

Deep learning analysis of the myocardium in coronary CT angiography for identification of patients with functionally significant coronary artery stenosis

Majd Zreik, Nikolas Lessmann, Robbert W. van Hamersvelt +5

In patients with coronary artery stenoses of intermediate severity, the functional significance needs to be determined. Fractional flow reserve (FFR) measurement, performed during…

The Engel-Lutz twist and overtwisted Engel structures

Álvaro del Pino, Thomas Vogel

We introduce a modification procedure for Engel structures that is reminiscent of the Lutz twist in 3-dimensional Contact Topology. This notion allows us to define what an Engel ov…

Loose Engel structures

Roger Casals, Álvaro del Pino, Francisco Presas

This article introduces the notion of a loose family of Engel structures and shows that two such families are Engel homotopic if and only if they are formally homotopic. This impli…

Largest and Smallest Area Triangles on Imprecise Points

Vahideh Keikha, Maarten Löffler, Ali Mohades

Assume we are given a set of parallel line segments in the plane, and we wish to place a point on each line segment such that the resulting point set maximizes or minimizes the are…

Lattice models with exactly solvable topological hinge and corner states

Flore K. Kunst, Guido van Miert, Emil J. Bergholtz

We devise a generic recipe for constructing -dimensional lattice models whose -dimensional boundary states, located on surfaces, hinges, corners, and so forth, can be obtaine…

The Mid-Pleistocene Transition induced by delayed feedback and bistability

Courtney Quinn, Jan Sieber, Anna S. von der Heydt +1

The Mid-Pleistocene Transition, the shift from 41 kyr to 100 kyr glacial-interglacial cycles that occurred roughly 1 Myr ago, is often considered as a change in internal climate dy…

Zero-dimensional Donaldson-Thomas invariants of Calabi-Yau 4-folds

Yalong Cao, Martijn Kool

We study Hilbert schemes of points on a smooth projective Calabi-Yau 4-fold . We define invariants by integrating the Euler class of a tautological vector bundle…

Partially Massless Fields During Inflation

Daniel Baumann, Garrett Goon, Hayden Lee +1

The representation theory of de Sitter space allows for a category of partially massless particles which have no flat space analog, but could have existed during inflation. We stud…

A uniqueness theorem in potential theory with implications for tomography-assisted inversion

Karl Fabian, Lennart V. de Groot

Inversion of potential field data is a central technique of remote sensing in physics, geophysics, neuroscience and medical imaging. In spite of intense research, uniqueness theore…

Excitonic dispersion of the intermediate-spin state in LaCoO revealed by resonant inelastic X-ray scattering

Ru-Pan Wang, Atsushi Hariki, Andrii Sotnikov +9

More than 50 years ago the electron-hole attraction was proposed to drive narrow gap semiconductors or semimetals to a new phase, the excitonic insulator. The experimental proof of…
