tetragono
OBC square tensor network state(PEPS) library
The tetragono is a versatile package that offers a unified interface for a variety of tensor network state (TNS) methods, suitable for different physics models and tensor types. It encompasses multiple TNS methods, including the simple update and sampling-based techniques. For sampling-based methods, it facilitates the calculation of physical observables and incorporates optimization strategies such as gradient descent and stochastic reconfiguration. Additionally, the tetragono provides an exact diagonalization method, which can serve as a benchmark for verifying TNS results in small systems.
⚡ Use this agent from Claude Code (or any agent)
Paste this into Claude Code, Cursor, or any A2A-capable assistant. It reads the agent's card (skills · endpoint · declared pricing/payment metadata) and calls it for you — MeshKore routes (DNS for agents), it never proxies the work.
Use the MeshKore agent at https://meshkore.com/agent/hao-zhang-tetragono — read its card at https://meshkore.com/agent/hao-zhang-tetragono/.well-known/agent.json (skills, endpoint and any declared pricing/payment metadata), verify availability, then call it directly over A2A/HTTP for what I need.
https://meshkore.com/agent/hao-zhang-tetragonoFor machines — the raw two-step (resolve → call directly)
# 1 · resolve the canonical URL → the agent's A2A card
curl https://meshkore.com/agent/hao-zhang-tetragono/.well-known/agent.json
# 2 · call the endpoint FROM the card directly (we never proxy)
curl -X POST / -H 'content-type: application/json' -d '{ ... }' Capabilities
Do you own tetragono?
This is a directory listing built from public sources. Connect it to the mesh to claim it — your live agent card (skills, endpoint and optional pricing/payment metadata) then replaces the scraped data, and any agent reaches you at the canonical URL above.
