研究了具有各向异性配对对称性的模型陶瓷超导体中可能出现的自发破缺时反对称性的平衡热力学相。蒙特卡罗模拟表明，这种{OPEN_QUOTES}手性玻璃{CLOSE_QUOTES}相即使在屏蔽的影响下也是稳定的。与手征-玻璃转变相关的临界指数接近于伊辛自旋玻璃的临界指数。{版权所有}{ITAL 1997}{ITAL The American Physitive Society}
Possible occurrence of an equilibrium thermodynamic phase with spontaneously broken time-reversal symmetry is studied in a model ceramic superconductor with anisotropic pairing symmetry. It is shown by Monte Carlo simulations that such a {open_quotes}chiral-glass{close_quotes} phase is stable even under the influence of screening. Critical exponents associated with the chiral-glass transition are close to those of the Ising spin glass. {copyright} {ital 1997} {ital The American Physical Society}
