FlowPy - a numerical solver for functional renormalization group equations
FlowPy numerical solver functional renormalization group equations
2012/2/29
FlowPy is a numerical toolbox for the solution of partial differential equations encountered in Functional Renormalization Group equations. This toolbox compiles flow equations to fast machine code an...
Exact density functional theory with the density matrix renormalization group
density functional theory density matrix renormalization group electronic structure models
2011/8/17
Abstract: Combining density functional theory with controlled numerical methods for strongly correlated systems could greatly extend the range of both. We use the density matrix renormalization group ...
The Similarity Renormalization Group with Novel Generators
Novel Generators Renormalization Group
2011/7/20
The choice of generator in the Similarity Renormalization Group (SRG) flow equation determines the evolution pattern of the Hamiltonian.
Non-equilibrium time evolution of bosons from the functional renormalization group
Non-equilibrium time evolution of bosons functional renormalization group
2010/11/25
We develop a functional renormalization group approach to obtain the time evolution of the
momentum distribution function of interacting bosons out of equilibrium. Using an external outscattering rat...
Evolving Nuclear Many-Body Forces with the Similarity Renormalization Group
Nuclear Many-Body Forces Similarity Renormalization Group
2011/1/6
In recent years, the Similarity Renormalization Group has provided a powerful and versatile
means to soften interactions for ab initio nuclear calculations. The substantial contribution of both induc...
Convergence of a renormalization group approach to dimer-dimer scattering
Convergence of a renormalization group dimer-dimer scattering
2011/1/10
We study the convergence of a functional renormalisation group technique by looking at the ratio between the fermion-fermion scattering length and the dimer-dimer scattering length for a system of non...
Functional renormalization group for quantized anharmonic oscillator
Functional renormalization group quantized anharmonic oscillator
2010/10/27
Functional renormalization group methods formulated in the real-time formalism are applied to
the O(N) symmetric quantum anharmonic oscillator, considered as a 0 + 1 dimensional quantum
field-theori...
A simple way to avoid metastable configurations in the density-matrix renormalization-group algorithms
spin model DMRG spin-1
2010/7/8
We use the spin-1 Heisenberg chain with periodic boundary conditions to ilustrate that the systems get stuck in metastable configurations only when the density-matrix renormalization-group algorithm s...

The Renormalization-Group Microscope: The Local Statistical Mechanics of Heterogeneous Systems
Renormalization-Group Microscope Heterogeneous Systems Local Statistical Mechanics
2010/4/16
Renormalization-group theory is developed to yield all local microscopic thermodynamic densities in heterogeneous systems. Local energy densities and local magnetizations are thus obtained for random-...
