Finite temperature dopant-induced spin reorganization explored via tensor networks in the two-dimensional - model
Yintai Zhang, Aritra Sinha, Marek M. Rams +1
We study the two-dimensional -- model at finite temperature directly in the thermodynamic limit using purification represented by an infinite projected entangled-pair state (…
Truncating loopy tensor networks by zero-mode gauge fixing
Ihor Sokolov, Yintai Zhang, Jacek Dziarmaga
Loopy tensor networks have internal correlations that often make their compression inefficient. We show that even local bond optimization can make better use of the insight it has…
Kibble-Zurek dynamical scaling hypothesis in the Google analog-digital quantum simulator of the model
Yintai Zhang, Francis A. Bayocboc, Jacek Dziarmaga
State-of-the-art tensor networks are employed to simulate the Hamiltonian ramp in the analog-digital quantum simulation of the quantum phase transition to the quasi-long-range orde…
Bang-bang preparation of a quantum many-body ground state in a finite lattice: optimization of the algorithm with a tensor network
Ihor Sokolov, Jacek Dziarmaga
A bang-bang (BB) algorithm prepares the ground state of a lattice quantum many-body Hamiltonian by evolving an initial product state alternating between and …
Comment on: "Dynamics of disordered quantum systems with two- and three-dimensional tensor networks" arXiv:2503.05693
Andrew D. King, Alberto Nocera, Marek M. Rams +8
In a recent preprint [1] (arXiv:2503.05693), Tindall et al. presented impressive classical simulations of quantum dynamics using tensor networks. Their methods represent a signific…
