Formation of brine channels in sea-ice
K. Morawetz, S. Thoms, B. Kutschan
Liquid salty micro-channels (brine) between growing ice platelets in sea ice are an important habitat for - binding microalgaea with great impact on polar ecosystems. The st…
Phase-field theory of brine entrapment in sea ice: Short-time frozen microstructures
Silke Thoms, Bernd Kutschan, Klaus Morawetz
We analyze the early phase of brine entrapment in sea ice, using a phase field model. This model for a first-order phase transition couples non-conserved order parameter kinetics t…
Stability of 3D Cubic Fixed Point in Two-Coupling-Constant ϕ^4-Theory
H. Kleinert, S. Thoms, V. Schulte-Frohlinde
For an anisotropic euclidean -theory with two interactions $[u (\sum_{i=1^M ϕ_i^2)^2+v \sum_{i=1}^M ϕ_i^4]$ the -functions are calculated from five-loop perturbation expans…
Resummation of anisotropic quartic oscillator. Crossover from anisotropic to isotropic large-order behavior
H. Kleinert, S. Thoms
We present an approximative calculation of the ground-state energy for the anisotropic anharmonic oscillator Using an instanton solution of the isotropic action , we obtain t…
Large-Order Behavior of Two-coupling Constant -Theory with Cubic Anisotropy
H. Kleinert, S. Thoms
For the anisotropic $[u (\sum_{i=1^N ϕ_i^2)^2+v \sum_{i=1^N ϕ_i^4]$-theory with {} we calculate the imaginary parts of the renormalization-group functions in the form of a s…
