Phase diagram of Rydberg atoms in a two-leg rectangular ladder
Shu-Ao Liao, Jin Zhang, Li-Ping Yang
Using the density matrix renormalization group algorithm, we map the ground-state phase diagram of a two-leg Rydberg ladder array with lattice spacings . We identify vari…

Simplex tensor network renormalization group for boundary theory of 3+1D symTFT
Kaixin Ji, Lin Chen, Li-Ping Yang +1
Following the construction in arXiv:2210.12127, we develop a symmetry-preserving renormalization group (RG) flow for 3D symmetric theories. These theories are expressed as boundary…

New Angular Momentum Conservation Laws for Gauge Fields in QED
Farhad Khosravi, Li-Ping Yang, Pronoy Das +1
Quantum electrodynamics (QED) deals with the relativistic interaction of bosonic gauge fields and fermionic charged particles. In QED, global conservation laws of angular momentum…
