Spin order, spin excitations, and RIXS spectra of spin-1/2 tetramer chains
Junli Li, Jun-Qing Cheng, Trinanjan Datta +1
We investigate the spin dynamics of a 1D spin-1/2 Heisenberg tetramer chain. Employing a combination of Density Matrix Renormalization Group, quantum renormalization group, and per…
Resonant inelastic x-ray scattering spectra of spinon, doublon, and quarton excitations of a spin- antiferromagnetic Heisenberg trimer chain
Junli Li, Jun-Qing Cheng, Trinanjan Datta +1
We investigate the excitation spectra of a spin-1/2 antiferromagnetic Heisenberg trimer spin chain by employing a combination of numerical and theoretical techniques. Utilizing the…
Quantum phase transitions and composite excitations of antiferromagnetic spin trimer chains in a magnetic field
Jun-Qing Cheng, Zhi-Yao Ning, Han-Qing Wu +1
Motivated by recent advancements in theoretical and experimental studies of the high-energy excitations on an antiferromagnetic trimer chain, we numerically investigate the quantum…
Magnon, doublon and quarton excitations in 2D S=1/2 trimerized Heisenberg models
Yue-Yue Chang, Jun-Qing Cheng, Hui Shao +2
We investigate the magnetic excitations of the trimerized Heisenberg models with intra-trimer interaction and inter-trimer interaction on four different two-dimensional…
Dynamical localization transition in the non-Hermitian lattice gauge theory
Jun-Qing Cheng, Shuai Yin, Dao-Xin Yao
Local constraint in the lattice gauge theory provides an exotic mechanism that facilitates the disorder-free localization. However, the understanding of nonequilibrium dynamics in…
