Role of long-range interaction in critical quantum metrology
Zhen-Xia Niu, Qian Wang
Long-range interacting quantum systems are useful for improving the performance of various applications of quantum technologies. In this work, we carry out a detailed analysis of h…
Multifractality and excited-state quantum phase transition in ferromagnetic spin- Bose-Einstein condensates
Zhen-Xia Niu, Qian Wang
Multifractality of quantum states plays an important role for understanding numerous complex phenomena observed in different branches of physics. The multifractal properties of the…
Excited stated quantum phase transitions and the entropy of the work distribution in the anharmonic Lipkin-Meshkov-Glick model
Haiting Zhang, Yifan Qian, Zhen-Xia Niu +1
Studying the implications and characterizations of the excited state quantum phase transitions (ESQPTs) would enable us to understand various phenomena observed in quantum many bod…
Precision magnetometry exploiting excited state quantum phase transitions
Qian Wang, Ugo Marzolino
Critical behaviour in phase transitions is a resource for enhanced precision metrology. The reason is that the function, known as Fisher information, is superextensive at critical…
