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.
Series expansions from the corner transfer matrix renormalization group method: the hard squares model
Corner transfer matrix hard squares model series expansions
2011/9/30
Abstract: The corner transfer matrix renormalization group method is an efficient method for evaluating physical quantities in statistical mechanical models. It originates from Baxter's corner transfe...
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...
Self-energy effects in the Polchinski and Wick-ordered renormalization-group approaches
Self-energy effects Polchinski Wick-ordered renormalization-group approaches
2010/12/16
I consider treatment of the self-energy effects in the functional renormalization group (fRG) schemes, which do not rely on the one-particle irreducible functional.
Generalized Central Limit Theorem and Renormalization Group
Central Limit Theorems Stable Distributions Characteristic Functions
2010/12/7
We introduce a simple instance of the renormalization group transformation in the Banach space of probability densities. By changing the scaling of the renormalized variables we obtain, as fixed point...
Renormalization group structure for sums of variables generated by incipiently chaotic maps
Renormalization group chaotic maps
2010/4/7
We look at the limit distributions of sums of deterministic chaotic variables in unimodal maps and find a remarkable renormalization group (RG) structure associated to the operation of increment of su...
We study theoretically the physical origin of the proposed discrete scale invariance of earthquake processes, at the origin of the universal log-periodic corrections to scaling, recently discovered in...
Renormalization group method for Farley-Buneman fluctuations:basic results
Renormalization group method Farley-Buneman fluctuations basic results
2009/11/16
Sudan and Keskinen in [1979] derived a set of equations governing the nonlinear evolution of density fluctuations in a low-pressure weakly ionized plasma driven unstable by the E x B or gradient-drift...
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...
