Statistical features of quantum chaos using the Krylov operator complexity
Zhuoran Li, Wei Fan
We study the statistical properties of Lanczos coefficients over an ensemble of random initial operators generating the Krylov space. We propose two statistical quantities that are…

Unify the effect of anharmonicity in double-wells and anharmonic oscillators
Wei Fan, Huipen Zhang, Zhuoran Li
We study the effect of anharmonicity in quantum anharmonic oscillators, by computing the energy gap between the ground and the 1st excited state using the numerical bootstrap metho…
