We study the dynamics of rogue wave excitations and quasi-transitions in one-dimensional quantum droplets, whose homogeneous-density flat top provides an applicable background wave for nonlinear excitation. Using a quenching technique and a localized s…
Ion-pair (IP) states are the superexcited states of the neutral molecule that dissociate as a pair of positive and negative ions. These states are generally present near the ionization continuum of the molecule. IP states can be accessed by using photo…
Graphene can be magnetized through nonlinear response of its orbital angular momentum to an intense circularly polarized light. This optomagnetic effect can be well exemplified by the inverse Faraday effect (IFE) where an optically-generated DC magneti…
The continuing improvement in the qualities of photon-number-resolving (PNR) detectors opens new possibilities for measuring quantum states of light. In this work we consider the question of what properties of an arbitrary multi-mode Gaussian state are…
We demonstrate double-peak spectral splitting in high-order harmonics generated in graphite plasma, which is mainly attributed to the propagation effects of high harmonics in the ionizing medium. The splitting of high harmonics can also be interpreted …
We employ two-dimensional electronic-vibrational (2DEV) spectroscopy to study the coherent dynamics of coupled vibrational modes in an excitonically-coupled dimer model. The advantage of separating excitation and detection in different frequency regime…
Detailed knowledge of the inner-shell atomic structure of lowly-ionised species is lacking for most elements along the sixth row of the periodic table, from hafnium to bismuth. This paper presents 4f-photoabsorption spectra of Pt+ to Pt4+ ions, recorde…
We present an approach to assess the survival of single-atom effects in the macroscopic high-harmonic generation (HHG) spectrum, by accounting for focal volume averaging. We apply this technique to R-matrix with time-dependence (RMT) studies, which are…

We investigate the steady-state quantum phases and associated collective phenomena of an open Tavis–Cummings (TC) model driven by a two-photon source. The standard (non-dissipative) TC model describes the quantum phases of an ensemble of Nq two-level q…
