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...

Although the adverse labor market effects of economic recessions have been well documented, a notable omission in the literature is how recessions impact workers’ job match quality. This paper considers the short and longer-term losses in productivity associated with the job changing brought...

Purpose: The purpose of this paper is to investigate the mechanism how the platform obtains and uses undisclosed information to determine individual borrowers’ credit score and to examine the effectiveness of credit scoring in predicting default. The motivation stems from the fact that there...
