Quantum Boltzmann equation for spin-dependent reactions in the kinetic regime
Martin L. R. Fürst, Markus Kotulla, Christian B. Mendl +1
We derive and analyze an effective quantum Boltzmann equation in the kinetic regime for the interactions of four distinguishable types of fermionic spin- particles, st…
Current fluctuations for anharmonic chains in thermal equilibrium
Christian B. Mendl, Herbert Spohn
We study the total current correlations for anharmonic chains in thermal equilibrium, putting forward predictions based on the second moment sum rule and on nonlinear fluctuating h…
Efficient algorithm for many-electron angular momentum and spin diagonalization on atomic subshells
Christian B. Mendl
We devise an efficient algorithm for the symbolic calculation of irreducible angular momentum and spin (LS) eigenspaces within the -fold antisymmetrized tensor product $\wedge^n…
Numerical scheme for a spatially inhomogeneous matrix-valued quantum Boltzmann equation
Jianfeng Lu, Christian B. Mendl
We develop an efficient algorithm for a spatially inhomogeneous matrix-valued quantum Boltzmann equation derived from the Hubbard model. The distribution functions are …
Numerical methods for a Kohn-Sham density functional model based on optimal transport
Huajie Chen, Gero Friesecke, Christian B. Mendl
In this paper, we study numerical discretizations to solve density functional models in the "strictly correlated electrons" (SCE) framework. Unlike previous studies our work is not…
Numerical test of hydrodynamic fluctuation theory in the Fermi-Pasta-Ulam chain
Suman G. Das, Abhishek Dhar, Keiji Saito +2
Recent work has developed a nonlinear hydrodynamic fluctuation theory for a chain of coupled anharmonic oscillators governing the conserved fields, namely stretch, momentum, and en…
