Dr. Bijit Mukherjee’s first NISER-affiliated publication explores a general method for tuning interactions between static-field-shielded ultracold molecules using microwave fields. The study demonstrates wide control over molecular interaction parameters while maintaining strong suppression of unwanted collisional losses.
🔹 𝗪𝗵𝘆 𝗧𝘂𝗻𝗲 𝗠𝗼𝗹𝗲𝗰𝘂𝗹𝗮𝗿 𝗜𝗻𝘁𝗲𝗿𝗮𝗰𝘁𝗶𝗼𝗻𝘀?
Precise control of molecular interactions is essential for exploring many-body quantum physics, quantum simulation, and strongly interacting ultracold systems.
🔹 𝗛𝗼𝘄 𝗗𝗼𝗲𝘀 𝘁𝗵𝗲 𝗠𝗲𝘁𝗵𝗼𝗱 𝗪𝗼𝗿𝗸?
The approach uses microwave fields to control interactions between ultracold polar molecules while suppressing destructive collisional losses under carefully controlled field conditions.
🔹 𝗪𝗵𝗮𝘁 𝗖𝗮𝗻 𝗕𝗲 𝗧𝘂𝗻𝗲𝗱?
The method enables wide tuning of both the s-wave scattering length and dipole length, providing flexible and precise control of molecular interactions.
🔹 𝗪𝗵𝗮𝘁 𝗠𝗮𝗸𝗲𝘀 𝗜𝘁 𝗦𝗶𝗴𝗻𝗶𝗳𝗶𝗰𝗮𝗻𝘁?
The work offers a general strategy for controlling interactions in static-field-shielded molecules while strongly suppressing loss, opening new possibilities for quantum simulations and the study of complex quantum systems.
