Toward spectral engineering of squeezed light in high-gain parametric down-conversion

Anonymous, Aleksa Krstić, Sina Saravi, Frank Setzpfandt

We investigated the spectral properties of squeezed light generated via parametric down-conversion in the high-gain regime, considering both unapodized and apodized dispersion-engineered waveguides. The gain-dependent evolution of these states is examined starting from the low-gain regime, which includes both highly correlated and …

Energy estimates for wave amplification in quasiperiodic Fibonacci time-modulated media

Anonymous, Bryn Davies

We show that Fibonacci time quasicrystals can be approximated by temporal supercells, which capture the nonperiodic but self-similar modulation in an analytically tractable form. This reveals a fractal hierarchy of instability gaps, indexed by the wave number k , in which wave …

Learning spectral density functions in open quantum systems

Anonymous, João Victor Shiguetsugo Kawanami Lima, Pedro Marcelo Prado, F. F. Fanchini et autres

Spectral density functions quantify how environmental modes couple to quantum systems and govern their open dynamics. Inferring such frequency-dependent functions from time-domain measurements is an ill-conditioned inverse problem. Here, we use exactly solvable spin-boson models with pure-dephasing and amplitude-damping channels to reconstruct …
