Spin modulations in the Rashba-Hubbard chain -- a tensor network study
Jozef Genzor, Roman KrÄmár, Andrej Gendiar +2
Uniform spin-orbit coupling in an open single-band Hubbard chain is an exactly removable \(SU(2)\) gauge field at the Hamiltonian level, but not at the level of laboratory-frame sp…

Solving the Gross-Pitaevskii Equation with Quantic Tensor Trains: Ground States and Nonlinear Dynamics
Qian-Can Chen, I-Kang Liu, Jheng-Wei Li +1
We develop a tensor network framework based on the quantic tensor train (QTT) format to efficiently solve the Gross-Pitaevskii equation (GPE), which governs Bose-Einstein condensat…
