论文摘要

在这封信中,我们在实验中验证了非遗传性统计场理论,这是一种新的一般现场理论方法,该方法最近在文献中引入了。通过这样的方法,我们能够计算经过连续相变的非xtxentive系统的关键属性,该系统属于新的通用O($ n $)$ _ {q} $通用类。我们比较了从理论中评估的无Xtentimentive临界指数值与通过实验在文献中已经获得的各种不同的锰矿所获得的值进行了比较。该协议是令人满意的,其相对错误的$ <5 \%$对所使用的大多数锰含量,并且与$ | 1- Q |更好。 <1 $这是理论有效性的极限。我们通过对$ Q $参数的一般物理解释对实验结果和理论的物理解释进行了解释。

In this Letter we validate experimentally the nonextensive statistical field theory, a new general field-theoretic approach introduced recently in the literature. With such an approach, we are capable of computing the critical properties of nonextensive systems undergoing continuous phase transitions, belonging to the new generalized O($N$)$_{q}$ universality class. We compare the nonextensive critical indices values evaluated from the theory with those already obtained in literature through experiments for various distinct manganites presenting nonconventional critical behavior. The agreement is satisfactory, whose relative errors are $< 5\%$ for the most of manganites employed and as better as $|1 - q| < 1$ which is the limit of validity of the theory. We present the physical interpretation of the experimental results and of the theory through the general physical interpretation of the $q$-parameter.
