Inspired by recent advances in observational astrophysics and continued explorations the field of analog gravity, we discuss prospect simulating models cosmology within context synthetic mechanical lattice experiments. We focus on physics expanding universe scenarios described Friedmann-Lemaître-Robertson-Walker (FLRW) metric. Specifically, quantizing scalar fluctuations a background FLRW spacetime leads to quadratic bosonic Hamiltonian with temporally varying pair production terms. Here...
Inspired by investigations of Bose-Einstein condensates (BECs) produced in the Cold Atom Laboratory (CAL) aboard International Space Station, we present a study thermodynamic properties shell-shaped BECs. Within context spherically symmetric ``bubble trap'' potential, evolution system from small filled spheres to hollow, large, thin shells via tuning trap parameters. We analyze bubble spectrum and states track distinct changes spectra between radial angular modes across evolution. This...
