在这篇文章中,我简要总结了DMFT方程的一种经典推导方法,即Martin-Siggia-Rose-de Dominicis-Janssen (MSRDJ) formalism。这篇小总结里我主要参考的是最近的两本关于神经网络统计物理的书[2][3]。由于有些词不好翻译,所以直接用英文写了... Network Architecture...
In deriving the theory, this chapter also presents the extension of the model to stochastic dynamics due to additive uncorrelated Gaussian white noise (Schuecker et al., Phys Rev X 8:041029, 2018).doi:10.1007/978-3-030-46444-8_10Moritz Helias...
Within dynamic mean field theory I have investigated two situations in which the validity of such an ansatz can be controlled or is not made. In both cases I find only a trivial form of ultrametricity. Especially for an adiabatically cooled SK-spin glass in a small external field a single ...
We investigate the attractive Hubbard model in infinite spatial dimensions by combining dynamical mean-field theory with a strong-coupling continuous-time ... A Koga,P Werner - 《Physical Review A》 被引量: 41发表: 2011年 Thermal Conductivity of a Heavy Fermion Superconductor UPd_2Al_3 Single ...
Application of mean-field theory in PP/ EVA blends by focusing on dynamic mechanical properties in correlation with miscibility analysis. Compo Part B-Eng 2015;79:74e82.Aghjeh, M.R.; Khonakdar, H.A.; Jafari, S.H. Application of mean-field theory in PP/EVA blends by focusing on ...
(…) spontaneous pattern formation is exactly what we mean byself-organization: the system organizes itself, but there is no ‘self’, no agent inside the system doing the organizing.” Thus, the individual parts of the system together make up a larger, more complex, and coherent whole. ...
By developing a mean-field theory, which we verify by simulations, we find coupled collective phenomena, including multistability, regions of coexistence, and macroscopic chaos. In interdependent dynamics, in particular, we observe hysteretic behaviours with abrupt (hybrid and explosive) transitions, ...
A relaxation-function theory for the dynamic spin susceptibility in the$t$--$J$ model is presented. By a sum-rule-conserving generalized mean-fieldapproxim... AA Vladimirov,D Ihle,NM Plakida - 《Physical Review B》 被引量: 0发表: 2009年 Evolution of the resonance and incommensurate spin...
which can describe the phenomena of local contacts and moving contacts in real life.Then we construct a SIR transmission model on the proposed network on the basis of mean-field theory.Simulations and analysis show that,with the increase of inter-community long range jump probabilities,the ...
6a, b, we found that neutral items encoded during high-valence music (i.e., more positive emotions) were statistically significantly better remembered as a function of increasing arousal (1 SD above the mean = 0.073; β = 0.08, p < 0.001, 95% CI = [0.03, 0.14])...
