spin-chains

QRC on disordered XXZ spin chains — temporal benchmarks, memory capacity, Pauli readout, Ridge regression, spintronic gate set.

Libraries for several quantum stuff.

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

Python library to solve spin chain Hamiltonians by exact diagonalization

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

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

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.

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

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

Reproducible numerical comparison of fixed open-chain and closed-ring four-qubit dynamics, including local responses, two-body connected correlations, eigenspace-pair decomposition, and numerical audits.

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
