Operadores de Ativação Espectral e Tempo Próprio Efetivo em Circuitos: Derivação pelo Protocolo Ação--Fase do Fator \(G(K)\)

Operadores de Ativação Espectral e Tempo Próprio Efetivo em Circuitos: Derivação pelo Protocolo Ação--Fase do Fator \(G(K)\)

Abstract

Este trabalho apresenta uma derivação variacional e espectral do fator geométrico \(G(K)\), associado à renormalização de tempo próprio efetivo em interfaces eletromagnéticas, circuitais e geométricas. No contexto do Protocolo Ação--Fase, parte-se da identificação\[ \phi_{\rm eff}=\frac{S_{\rm eff}}{\hbar},\]com uma ação efetiva única\[ S_{\rm eff} = S_{\rm padrao} + S_{\rm espectral} + S_{\rm int}.\]O operador de ativação é definido como o Hessiano variacional da ação,\[ K=\delta^2S_{\rm eff}\big|_{\mathcal C},\]evitando sua introdução como parâmetro fenomenológico. No regime regular, \(K\) admite decomposição espectral,\[ K=\int_{\sigma(K)}\lambda\,dE_K(\lambda),\]e, para uma excitação \(\psi\), define-se a medida\[ d\mu_\psi^K(\lambda) = d\langle\psi,E_K(\lambda)\psi\rangle.\]A ativação relevante é a parte filtrada que se afasta do fundo estacionário, descrita pelo funcional\[ \mathcal A_K[\psi] = \int_{\sigma(K)} a(\lambda)\,d\mu_{\psi,{\rm ativo}}^K(\lambda), \qquad a(\lambda)\geq0.\]Dessa construção deriva-se a resposta geométrica regular de menor ordem,\[ G(K)=1-C\alpha\mathcal A_K[\psi]+O(\mathcal A_K^2),\]ou, no truncamento linear,\[ G(K)=1-C\alpha\mathcal A_K[\psi].\] Com \(00.\]
