Tunable two-component ultracold molecular gases with vibrational shielding
Bijit Mukherjee, MichaÅ Tomza
We propose a method to realize stable, tunable two-component quantum mixtures of ultracold polar molecules. First, we show that a pair of polar molecules in two distinct rovibratio…
Tuning interactions between static-field-shielded polar molecules with microwaves
Christopher J. Ho, Joy Dutta, Bijit Mukherjee +2
The ability to tune interparticle interactions is one of the main advantages of using ultracold quantum gases for quantum simulation of many-body physics. Current experiments with…
Optical excitation and stabilization of ultracold field-linked tetratomic molecules
Bijit Mukherjee, MichaÅ Tomza
We propose a coherent optical population transfer of weakly bound field-linked (FL) tetratomic molecules (tetramers) to deeper FL bound states using stimulated Raman adiabatic pass…
Effective anisotropic interaction potentials for pairs of ultracold molecules shielded by a static electric field
Bijit Mukherjee, Luis Santos, Jeremy M. Hutson
Quantum gases of ultracold polar molecules have novel properties because of the strong dipolar forces between molecules. Current experiments shield the molecules from destructive c…
Universality in the microwave shielding of ultracold polar molecules
Joy Dutta, Bijit Mukherjee, Jeremy M. Hutson
Microwave shielding is an important technique that can suppress the losses that arise from collisions of ultracold polar molecules. It has been instrumental in achieving molecular…
SU() symmetry with ultracold alkali dimers: weak dependence of scattering properties on hyperfine state
Bijit Mukherjee, Jeremy M. Hutson
We investigate the prospect of using ultracold alkali diatomic molecules to implement many-body quantum systems with SU() symmetry. Experimentally accessible molecules offer lar…
