Físicos criam primeira molécula ultrafria em formato de borboleta

Pesquisadores produziram uma molécula exótica que se assemelha a uma borboleta, com asas de elétrons, ao combinar átomos de rubídio gigantes e de tamanho normal. O feito conclui uma busca de duas décadas por uma família desses gigantes moleculares e pode permitir novos avanços na ciência quântica.

A molécula foi montada na Universidade RPTU Kaiserslautern-Landau, na Alemanha. Os cientistas resfriaram átomos de rubídio a alguns milionésimos de grau acima do zero absoluto e, em seguida, usaram lasers para ampliar drasticamente alguns átomos antes de ligar um elétron externo a um átomo vizinho. A estrutura resultante mede aproximadamente 25 nanômetros de diâmetro e responde a campos elétricos com muito mais intensidade do que moléculas comuns.
