TetrisCNN for interpretable detection of phases of matter from experimental quantum simulator data

TetrisCNN is a convolutional neural network that uses parallel branches of differently shaped filters to learn sparse, interpretable latent representations directly from spin correlators. Applied to experimental snapshots of two-dimensional Ising and XY quantum simulators, it detects phase transitions and crossovers while expressing its decision boundaries as symbolic formulas built from measurable spin correlators. This approach bridges the gap between black‑box neural networks and physically interpretable models, enabling automated discovery of new phases of matter from realistic, noisy experimental data.

TetrisCNN for interpretable detection of phases of matter from experimental quantum simulator data

TetrisCNN is a convolutional neural network that uses parallel branches of differently shaped filters to learn sparse, interpretable latent representations directly in terms of spin correlators. Applied to experimental snapshots from two-dimensional Ising and XY quantum simulators measured in multiple bases, the network detects phase transitions and crossovers while expressing its decision boundaries as symbolic formulas built from experimentally measurable spin correlators. This approach bridges the gap between black‑box neural network methods and physically interpretable models, enabling automated detection of phases of matter from realistic, noisy experimental data.

Direct/adaptive-mixture phase-gradient learning for neural-network quantum states with complex phase structure

arXiv:2606. 13912v1 Announce Type: cross Abstract: Neural-network quantum states (NQS) are a leading variational tool for quantum many-body physics, yet their optimization is fragile whenever the ground state carries a non-trivial sign or complex phase structure, a situation generic to gauge fields, broken time-reversal symmetry, and fermionic statistics.

Computing stable configurations of confined smectic liquid crystals with a deep variational framework

The paper introduces a deep variational framework (DVF) for computing stable configurations of confined smectic liquid crystals using a modified Landau–de Gennes model. By representing orientational and positional order parameters on a regular reference domain and incorporating physical confinement through coordinate mappings, the DVF overcomes spectral bias with a warmup penalty, enabling robust recovery of oscillatory smectic states. The method reproduces known smectic‑A defect structures, predicts new layer morphologies in various confinement geometries, and even forecasts a chevron‑like smectic‑C state on a tangent‑anchored sphere.
