Description
Short-range correlations in bosonic Helium clusters, composed of $^4$He atoms, are studied utilizing the generalized contact formalism. The emergence of universal $n$-body short-range correlations, associated with the repulsive $1/r^{12}$ part of the Lennard-Jones potential, is formulated and demonstrated numerically via Monte Carlo simulations. The values of the $n$-particle contacts are evaluated for $n\le5$. In the thermodynamic limit, the two-body contact is extracted from available experimental measurements of the static structure factor of liquid $^4$He at high momenta, and found in a good agreement with the value extracted from our calculations.
