In interacting many-body systems with chemical reactions, a key question is about how two-body decay depends on quantum correlations in interacting many-body systems. Here, we present a number of universal relations that directly connect two-body losses to other physical observables, including the momentum distribution and density correlation functions. These relations, which are valid for...
The Gailitis-Damburg oscillations are the near threshold singularities of cross-sections of reactive scattering predicted to exist in some atomic systems [1, 2, 3]. Namely, above the threshold of excited state of neutrally charged atom an infinite series of logarithmically spaced maxima and minima of cross-section can arise. Although this phenomenon was predicted in the early 1960s, there is...
We present a theoretical study of resonance lifetimes in a two-component three-body system, specifically examining the decay of three-body resonances into a deep dimer and an unbound particle. Utilising the Gaussian expansion method together with the complex scaling method, we obtain the widths of these resonances from first principles. We focus on mass ratios in the typical range for mixtures...
An investigation considering the emergence of Rayleigh-Taylor (RT) and Kelvin-Helmholtz (KH) instabilities, which occur in initially immiscible configuration of homogeneous Bose-Einstein condensates confined in a two-dimensional circular box, will be reported. For the binary mixture, it has been considered the rubidium isotopes $^{85}$Rb and $^{87}$Rb. As verified, more sound wave generations...

In the standard Big Bang Nucleosynthesis (BBN) framework, the primitive ${^6{Li}}$ abundance is mainly determined by two nuclear reactions: the
$d(\alpha,\gamma ){^6{Li}}$ reaction, where deuteron reacts with an alpha particle to produce ${^6{Li}}$. This reaction leads to the formation of ${^6{Li}}$ during the primordial nucleosynthesis process. Conversely, ${^6{Li}}(p,\alpha ){^3{He}}$, can...
