A diagonalization-free Krylov (bi-Lanczos/Arnoldi) construction yields exact or truncated adiabatic gauge potentials for non-Hermitian STA, reducing them to sparse matrix equations that suppress nonadiabatic excitations and detect PT/EP transitions.

Bloch oscillations emerge in continuum interacting quantum gases via strong interactions and are captured by generalized hydrodynamics in the Yang-Gaudin model, with finite-density renormalization from bound states.
A quantum Zeno dynamics protocol confines the evolution of a finite-time Otto-cycle quantum heat engine to a subspace that preserves instantaneous energy populations, recovering quasistatic efficiency with added thermodynamic costs from monitoring and switching.
Perfect displacement of superconducting resonators is achieved via fast-forward scaling of drive amplitude or detuning, enabling high-speed R_ZZ gates in Kerr-cat qubits.
