Unified non-Markovian, nonsecular microscopic theory of collisional redistribution of radiation in strong resonant laser fields
Finite-N validity of the large-N structured-phase coarsening exponents in the N-component Ginzburg–Landau model of self-assembled fluids, and the asymptotic growth law of the single-component Swift–Hohenberg equation
Atomic Fabry-Perot interferometer in a gravitational cavity: a coherent multi-round-trip matter-wave resonator with observable quantum modes
Completing the microscopic theory of inversionless gain at the central resonance of the Mollow absorption spectrum: strong-coupling amplification conditions, the proposed collisional and two-photon-pumped laser schemes, and convergence of the diagrammatic series
Mode-resolved atomic gravitational cavity: realistic mirror potentials, loss budgets, non-paraxial modes, and mode-selective loading
Origin of the near-zero-momentum behavior of the momentum distribution in subrecoil laser cooling: the weak deviation from Lévy-statistics predictions at $\zeta\simeq5$ in the nonergodic cooling of metastable helium
