In this work we evaluate quantum Fisher information (QFI) of the Ising-XXZ diamond structure at finite temperatures, which is applied to demonstrate the quantum criticality and quantum phase transition in this model. The results show that QFI around quantum critical points decreases or increases...

We develop and estimate a dynamic model to study the impact of student debt on education, career, and marriage market choices of young female lawyers. Our model accounts for several important institutional features of the labor market for lawyers, including differences in the work hours across...
