La carrera por el cero absoluto: el enfriamiento por láser

The video tutorial discusses the scientific pursuit of reaching absolute zero, a temperature where atomic motion ceases. Initially, scientists used liquefied gases to achieve temperatures close to absolute zero. In the early 1990s, advancements in laser cooling allowed for even lower temperatures. Evaporative cooling techniques further reduced temperatures, leading to a competitive race between teams from Colorado and MIT. In 1995, the Colorado team succeeded in cooling rubidium to a record low temperature, earning a Nobel Prize. Despite these achievements, scientists like Ketterly continue to strive for even lower temperatures.
