Tạp chất trung hòa trong ngưng tụ Bose-Einstein để mô phỏng polaron Fröhlich
Tóm tắt
Chúng tôi trình bày một hệ thống thí nghiệm để nghiên cứu polaron Bose bằng cách nhúng các tạp chất Cs trung hòa, có khả năng kiểm soát tốt, vào một ngưng tụ Bose-Einstein (BEC) của Rb. Chúng tôi chỉ ra rằng, bằng cách sử dụng các cái bẫy quang học thích hợp, việc kiểm soát độc lập đối với tạp chất và BEC cho phép định vị tương đối chính xác giữa hai hệ phụ này cũng như cho các nghiên cứu động lực học và đọc dữ liệu độc lập. Hơn nữa, chúng tôi ước tính rằng việc đo năng lượng liên kết polaron của các polaron Bose kiểu Fröhlich trong chế độ liên kết thấp và trung bình là khả thi với các ràng buộc và giới hạn thí nghiệm mà chúng tôi đã thảo luận, và chúng tôi chỉ ra cách mà một chế độ tham số có thể đạt được nhằm xác định sự khác biệt giữa polaron Fröhlich và polaron Bose trong chế độ liên kết mạnh.
