A universal theory of spin squeezing and the experimental realization
Abstract: Quantum metrology makes use of many-body entangled states to perform measurements with greater precision than would be possible using only classically correlated particles. Discerning state...

Eigenvalue relation of the Heisenberg chain with various boundary conditions for the ground state
Abstract: We propose a new parametrization of the eigenvalues of transfer matrix in a quantum integrable model. Based on it, we obtain the exact solution of the system. By studying the distribution o...
