Why Is There Universal Macro-Behavior?Renormalization Group Explanation As Non-causal Explanation
explanation non-causal explanation renormalization group explanation universality
2016/6/15
Renormalization group (RG) methods are an established strategy to explain how it is possible that microscopically different systems exhibit virtually the same macro behavior when undergoing phase-tran...
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 ...

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...
