Localization-constrained sparse quantum dictionaries trained on baker-map eigenstates spontaneously recover scar-like atoms aligned with classical periodic orbits.
Ising models after symmetry-breaking quenches show temporal collapse of order-parameter fluctuations, implying a new dynamical critical exponent above a lower critical effective dimension.
fTDHF extends time-dependent Hartree-Fock to fermionized spin-1/2 Hamiltonians, remaining exact for free fermions while handling non-local strings via non-orthogonal Slater determinant transitions and reproducing qualitative dynamics in three benchmark models.
Spin-adapted neural-network backflow (SA-NNBF) enforces total spin, removes spin contamination, and matches large-DMRG FeMoco energies with far fewer parameters.
An algorithm leveraging the Clifford group and graph representation to find symmetries in many-body Hamiltonians, demonstrated on random and physical instances up to 1000 qubits.
A statistical mixture of Tanh and Swish activations with critical mixing fraction p_c induces a continuous phase transition to scale-invariant signal propagation in deep networks while preserving smoothness.
Neural wave functions uncover FFLO, polarized superfluid, phase-separated, and crystalline Cooper-pair phases in the 2D spin-imbalanced Fermi gas.
Quantum spin glasses show an intermittent eigen-spectrum with alternating bands of z-type (classical spin-glass inheriting) and x-type (x-magnetization conserving) non-ergodic extended states.
DMRG calculations on the two-leg Lieb ladder Hubbard model identify a ferrimagnetic insulator at half filling and a narrow superconducting Luther-Emery phase near filling 2/3.
