Quantum Phase Transitions of Polar Molecules in Bilayer Systems
Quantum Phase Transitions of Polar Molecules in Bilayer Systems
We investigate the quantum phase transitions of bosonic polar molecules in a two-dimensional double layer system. We show that an interlayer bound state of dipoles (dimers) can be formed when the dipole strength is above a critical value, leading to a zero-energy resonance in the interlayer $s$-wave scattering channel.
