Intertwined spin and charge dynamics in one-dimensional supersymmetric t-J model
Yunjing Gao, Jianda Wu
Following the Bethe ansatz we determine the dynamical spectra of the one-dimensional supersymmetric t-J model. A series of fractionalized excitations are identified through two set…
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…
Discrete time crystal and perfect many-body tunneling in a periodically driven Heisenberg spin chain
Xiaotong Chen, Jianda Wu
We investigate the non-equilibrium dynamics of a Heisenberg spin-1/2 chain driven by a periodic magnetic field. Based on its instantaneous integrability and inherent symmetry, we a…
Mesons in a quantum Ising ladder
Yunjing Gao, Yunfeng Jiang, Jianda Wu
When two transverse-field Ising chains (TFICs) with magnetic order are coupled, the original free excitations become confined, giving rise to meson-like bound states. In this work,…
Thermally activated detection of dark particles in a weakly coupled quantum Ising ladder
Yunjing Gao, Jiahao Yang, Huihang Lin +2
The Ising integrable field theory emerges when two quantum critical Ising chains are weakly coupled. This theory possesses eight types of relativistic particles, among which…
