Cooling atomic gases to a quantum regime often involves time-consuming steps. Electromagnetically induced transparency now achieves quantum degeneracy with high efficiency.<\/p>\n\n\n\n

Quantum gas is a novel, non-classical state of matter, alongside gas, liquid, solid, and plasma states. In recent years, quantum gases have played a crucial role in the development of quantum science and technology, with many breakthroughs relying on experimental advancements in quantum gas studies. <\/p>\n\n\n\n

The condition for a regular gas to transition into a quantum gas is when the de Broglie wavelength of individual atoms exceeds the atomic spacing, a transition that can be facilitated by cooling, which increases the wavelength of matter waves. <\/p>\n\n\n\n

Since Nobel laureates Prof. Eric Cornell and Carl Wieman first experimentally observed quantum gases in 1995, their creation has largely depended on evaporative cooling, a process akin to cooling hot water by letting it evaporate at room temperature. However, this cooling method is inefficient and requires time for atomic collisions to occur.<\/p>\n\n\n\n

In a recent study published in Nature <\/a>Physics, a quantum science research team led by Associate Professor Shau-Yu Lan at National Taiwan University\u2019s Department of Physics demonstrated an exceptionally efficient method for producing quantum gases.<\/p>\n\n\n\n

This method involves trapping atoms in a three-dimensional optical lattice created by laser interference and employing electromagnetically induced transparency (EIT) along with adiabatic expansion to rapidly cool the atoms, achieving nearly 100% efficiency with a speed roughly 100 times faster than conventional methods. This innovative technique has significant potential to enhance applications of cold atom platforms in quantum sensing and quantum computing.<\/p>\n\n\n\n

Additionally, Professor Lan\u2019s team observed a phenomenon in the generated quantum gas resembling a supernova explosion, termed a \u201cBosenova\u201d explosion. This holds substantial implications for quantum simulation and many-body physics research. <\/p>\n\n\n\n

The image above illustrates the \u201cBosenova\u201d collapse of the quantum gas, where the central part represents the quantum gas formed within a three-dimensional optical lattice via electromagnetically induced transparency and adiabatic expansion techniques. After the \u201cBosenova\u201d collapse, atoms collide and emit a large quantity of atomic jets, forming a shell-like structure.<\/p>\n","protected":false},"excerpt":{"rendered":"
