Python library to solve spin chain Hamiltonians by exact diagonalization

A python toolbox for calculations on one dimensional quantum spin chains. Includes model Hamiltonians, operators, symmetries, spectrum analysis, entropy calculations, and examples.

Libraries for several quantum stuff.

Python implementations of Monte Carlo methods in Physics: From the Ising Model to Diffusion QMC and Stochastic Series Expansion (SSE).

Matlab code for quantum spin-1/2 networks. It provides code to analyse the geometry of such networks, and some basic quantum control and characterisation code.

Music from the dynamics of a simulated discrete time crystal, in real time, over MIDI & OSC.

Regime diagnostics for spatiotemporal kernels K(r,t), 1D-4D: transport × coherence classification, isotropic S(k,ω) via Hankel/spherical-Bessel, plus stateflow — a domain-agnostic trajectory layer. NumPy/SciPy only. pip install kernel-dynamics-viewer

A library to calculate the thermodynamic properties of a 1D Ising spin chain with beyond nearest-neighbor interactions.

Palindromic Liouvillian symmetry under dephasing: proven for any Heisenberg graph, verified N=2–8 (87,376 eigenvalues, zero exceptions). Absorption Theorem Re(λ) = −2γ⟨n_XY⟩, golden-ratio mirrors, noise that reads its own spectrum; 17 predictions confirmed on IBM hardware. A living research notebook, Thomas Wicht & Claude. R = CΨ²
