Numerical renormalization group integrated Hamiltonian truncation: Toward generic deformation of integrable lattice models
Xiaodong He, Xiao Wang, Jianda Wu
We present a hybrid lattice Hamiltonian truncation method that integrates the numerical renormalization group (NRG) with a truncated lattice integrable spectrum. The technique is t…

Berry connection and quantum geometry in time-dependent systems with instantaneous quantum integrable field theory
Xiao Wang, Xiaodong He, Jianda Wu
We study many-body quantum geometric effects in time-dependent system with emergent quantum integrable field theory instantaneously. We establish a theorem stating that the Berry c…
