Nettet13. jul. 2011 · 1. Introduction. Key concepts of contemporary theoretical physics such as universality, self-similarity, scaling, data collapse and asymptotic freedom are directly associated with the development of the renormalization group (RG) ideas [1–3].The RG method consists of ‘thinning down’ the degrees of freedom in problems involving a … Nettet16. apr. 2024 · Scaling dimensions from linearized tensor renormalization group transf ormations Xinliang Lyu , 1 , * RuQing G.

NettetOne class, called real space renormalization group (RSRG), eliminates local lattice-based degrees of freedom at each step in the RG process. The second class, called momentum space renormalization group (MSRG), is implemented by systematically lowering the cutoff Λ in the wavevector integrals. It turns out that the RSRG process, for … Nettet19. sep. 2007 · We describe a simple real space renormalization group technique for two-dimensional classical lattice models. The approach is similar in spirit to block spin methods, but at the same time it is fundamentally based on the theory of quantum entanglement. In this sense, the technique can be thought of as a classical analogue of … Nettet6. des. 2016 · Linearized tensor renormalization group (LTRG) [21, 22] can compute infinitelength system and thus provide an accurate access to the full-temperature range … the dj fnaf
