Strong Violation of Critical Phenomena Universality Under Quenched Bond Randomness
The empirically long-established principle of universality states that, along a second-order phase boundary between any two given phases, the critical exponents are invariant. We find that this universality is strongly violated under quenched bond randomness, in the sense that the critical exponents abruptly change their values between two segments of the same second-order phase boundary.
