In this paper, we consider the following coupled nonlinear Schrödinger system

$ \left\{\begin{array}{ll} -\Delta u+(1+\delta a(x))u = \mu_1 u^3+\beta uv^2 &\mbox{in }\mathbb{R}^3,\\ -\Delta v+(1+\delta b(x))v = \mu_2 v^3+\beta u^2v &\mbox{in }\mathbb{R}^3,\\ u\to 0,\quad v\to 0, &\mbox{as } |x|\to\infty \end{array}\right. $

where

$ \mu_1>0 $

$ \mu_2>0 $

$ \beta\in\mathbb{R} $

$ \delta\in\mathbb{R} $

, and

$ a(x) $

and

$ b(x) $

are two

$ C^\alpha $

potentials with

$ 0<\alpha<1 $

, satisfying some slow decay assumptions, but do not need to fulfill any symmetry property. Using the Lyapunov–Schmidt reduction method and some variational techniques, we show that there exist

$ 0<\delta_0<1 $

and

$ 0<\beta_0<\min\{\mu_1,\mu_2\} $

such that the above system has infinitely many positive segregated solutions for any

$ 0<\delta<\delta_0 $

and

$ 0<\beta<\beta_0 $

Keywords: Schrödinger system, Lyapunov–Schmidt reduction, segregated solutions.
