In this paper, we discuss thermodynamics for spherically symmetric and static traversable wormholes which include Morris–Thorne wormholes and charged wormholes in the background of f(R,T) gravity. The local coordinates have been used to find trapping horizons of these objects and generalized surface gravity has been worked out on the trapping horizons. The expression for the unified first law has also been derived from the gradient of Misner–Sharp energy with the help of gravitational field equations and from this law the first law of wormhole dynamics has been obtained. We have done this analysis for the simplest case of f(R,T) gravity where f(R,T) = R + 2λ1T, R and T being the traces of the Ricci and stress–energy tensors. Also, we have extended these thermodynamic results to non-minimal curvature-matter coupling.

f(R,T)重力下可穿越虫洞的热力学

在本文中，我们讨论了球对称和静态可穿越虫洞的热力学，包括莫里斯-索恩虫洞和带电虫洞。F(R,吨)重力。局部坐标已被用于寻找这些物体的圈闭层位，并在圈闭层位上计算出广义表面重力。统一第一定律的表达式也是借助引力场方程从米斯纳-夏普能量梯度推导出来的，并由此得到了虫洞动力学第一定律。我们已经对最简单的情况进行了分析F(R,吨)重力在哪里F(R,吨) = R + 2λ1吨,R和吨是里奇和应力-能量张量的痕迹。此外，我们将这些热力学结果扩展到非最小曲率物质耦合。
