Lee-Yang zeros at and deconfined quantum critical points
Jonathan D'Emidio
Lee-Yang theory, based on the study of zeros of the partition function, is widely regarded as a powerful and complimentary approach to the study of critical phenomena and forms a f…

Stable computation of entanglement entropy for 2D interacting fermion systems
Gaopei Pan, Yuan Da Liao, Weilun Jiang +3
There is no doubt that the information hidden in entanglement entropy (EE), for example, the -th order Rényi EE, i.e., $S^{A}_n=\frac{1}{1-n}\ln \Tr (ρ_A^n)$ where $ρ_A=\mathrm{…
