Summary

Story summary

Researchers introduce a tensor-network method to calculate momentum-resolved dispersion relations using imaginary-time evolution in the infinite projected entangled-pair states (iPEPS) framework.
The approach enables accurate dispersion relations for three-dimensional quantum lattice models with modest computational resources.
Benchmarking on the transverse-field Ising model shows strong agreement with series-expansion methods.
This method supports efficient 2D/3D state representation and informs quantum materials design.
