Conservative-dissipative approximation schemes for a generalized Kramers equation
Manh Hong Duong, Mark A. Peletier, Johannes Zimmer
We propose three new discrete variational schemes that capture the conservative-dissipative structure of a generalized Kramers equation. The first two schemes are single-step minim…
Subsonic phase transition waves in bistable lattice models with small spinodal region
Michael Herrmann, Karsten Matthies, Hartmut Schwetlick +1
Phase transitions waves in atomic chains with double-well potential play a fundamental role in materials science, but very little is known about their mathematical properties. In p…
Ion beam synthesis of nanothermochromic diffraction gratings with giant switching contrast at telecom wavelengths
Johannes Zimmer, Achim Wixforth, Helmut Karl +1
Nanothermochromic diffraction gratings based on the metal-insulator transition of are fabricated by site-selective ion beam implantation in a matri…
Large deviations and gradient flows
Stefan Adams, Nicolas Dirr, Mark A. Peletier +1
In recent work [1] we uncovered intriguing connections between Otto's characterisation of diffusion as entropic gradient flow [16] on one hand and large-deviation principles descri…
