SU(N) magnetism with ultracold molecules (2025)
Journal Article
Mukherjee, B., Hutson, J. M., & Hazzard, K. R. A. (2025). SU(N) magnetism with ultracold molecules. New Journal of Physics, 27(1), Article 013013. https://doi.org/10.1088/1367-2630/ad89f2

Quantum systems with SU(N) symmetry are paradigmatic settings for quantum many-body physics. They have been studied for the insights they provide into complex materials and their ability to stabilize exotic ground states. Ultracold alkaline-earth ato...

Controlling collisional loss and scattering lengths of ultracold dipolar molecules with static electric fields (2024)
Journal Article
Mukherjee, B., & Hutson, J. M. (2024). Controlling collisional loss and scattering lengths of ultracold dipolar molecules with static electric fields. Physical Review Research, 6(1), Article 013145. https://doi.org/10.1103/physrevresearch.6.013145

Trapped samples of ultracold molecules are often short-lived because close collisions between them result in trap loss. We investigate the use of shielding with static electric fields to create repulsive barriers between polar molecules to prevent su...

Shielding collisions of ultracold CaF molecules with static electric fields (2023)
Journal Article
Mukherjee, B., Frye, M. D., Le Sueur, C. R., Tarbutt, M. R., & Hutson, J. M. (2023). Shielding collisions of ultracold CaF molecules with static electric fields. Physical Review Research, 5(3), Article 033097. https://doi.org/10.1103/physrevresearch.5.033097

We study collisions of ultracold CaF molecules in strong static electric fields. These fields allow the creation of long-range barriers in the interaction potential, effectively preventing the molecules from reaching the short-range region where inel...

Magnetic Feshbach resonances between atoms in $^2$S and $^3$P$_0$ states: mechanisms and dependence on atomic properties (2023)
Journal Article
Mukherjee, B., Frye, M. D., & Hutson, J. M. (2023). Magnetic Feshbach resonances between atoms in $^2$S and $^3$P$_0$ states: mechanisms and dependence on atomic properties. Physical Review Research, 5, Article 013102. https://doi.org/10.1103/physrevresearch.5.013102

Magnetically tunable Feshbach resonances exist in ultracold collisions between atoms in 2 S and 3 P 0 states, such as an alkali-metal atom colliding with Yb or Sr in a clock state. We investigate the mechanisms of these resonances and identify the te...

Feshbach resonances and molecule formation in ultracold mixtures of Rb and Yb(3P) atoms (2022)
Journal Article
Mukherjee, B., Frye, M. D., & Hutson, J. M. (2022). Feshbach resonances and molecule formation in ultracold mixtures of Rb and Yb(3P) atoms. Physical Review A, 105(2), Article 023306. https://doi.org/10.1103/physreva.105.023306

We have investigated magnetically tunable Feshbach resonances in ultracold collisions of Rb with Yb in its metastable 3P2 and 3P0 states, using coupled-channel scattering and bound-state calculations. For the 3P2 state, we find sharp resonances when... Read More about Feshbach resonances and molecule formation in ultracold mixtures of Rb and Yb(3P) atoms.
