Query: Quantum Bose-Bose droplets at a dimensional crossover   We study a liquid quantum droplets in a mixture of two-component
Bose-Einstein condensates under a variable confinement introduced along one or
two spatial dimensions. Despite the atom-atom scattering has a
three-dimensional character, discreetness of the available modes in the reduced
dimension(s) strongly influences the zero-point energy -- the Lee-Huang-Yang
term. In a weakly interaction limit, it is the leading correction to the
mean-field energy at the crossover from three to two dimensions, or from three
to one dimension. We analyze the properties of the droplets at the dimensional
crossovers, and provide the demanding conditions for accessing quasi-low
dimensions. We predict new kinds of droplets which are formed only due to the
quantum fluctuations when the mean-field interaction vanishes. Our results pave
the way for exploring new states of quantum matter, and are important for
experiments with liquid quantum droplets in reduced dimensions.
