dc.description.abstract (摘要) | We study the distribution of finite-size pseudocritical points in a one-dimensional random quantum magnet with a quantum phase transition described by an infinite randomness fixed point. Pseudocritical points are defined in three different ways: the position of the maximum of the average entanglement entropy, the scaling behavior of the surface magnetization, and the energy of a soft mode. All three lead to a log-normal distribution of the pseudocritical transverse fields, where the width scales as L−1/ν with ν=2 and the shift of the average value scales as L−1/νtyp with νtyp=1, which we related to the scaling of average and typical quantities in the critical region. | en_US |
