I'm curious what the biggest size of Bosenova technically feasible. Is it possible to get into milligrams range?
Thx...

A bosenova or bose supernova is a very small, supernova-like explosion, which can be induced in a Bose–Einstein condensate(BEC) by changing the magnetic field in which the BEC (Bose-Einstein Condensate) is located so that the BEC quantum wavefunction's "self-scattering" interaction due to the Feshbach resonance transitions from repulsive to attractive, causing the BEC to "collapse and bounce" or "rebound."[1]
Although the total energy of the explosion is very small, the "collapse and bounce" scenario superficially and quite vaguely resembles (albeit is physically quite unrelated to) a tiny core-collapse supernova, hence the term 'bosenova'. (The nomenclature is also partly a play on the Brazilian music style, bossa nova.)
DrClaude said:I don't see any reason there would be some upper limit, apart from technical difficulties. It simply corresponds to changing the collisional properties of the atoms in a BEC through a Feshbach resonance, so it could in principle be as big as any BEC can be.
No. I think that current BECs can reach 108 to 109 atoms, and I don't think that this number can be increased that much in the near future. You have to remember that BEC represents a metastable state: at the low temperatures reached, these atoms should form a solid block, so the gases are quite dilute.stefanbanev said:Thanks for the answer ... does it mean that in your opinion to get into milligrams range is technically feasible?
I don't know what hoe big is the biggest, but probably in the 106-107 range. Scientifically, bosenovas are not that interesting, and I don't think anyone is trying to make large ones.stefanbanev said:What the biggest size Bosenova has been observed in the laboratory so far?

A Bosenova is a phenomenon that occurs when a Bose-Einstein condensate (BEC) undergoes a rapid expansion, causing it to release a burst of energy. This energy release is similar to a supernova in stars, hence the name "Bosenova".
A Biggest Bosenova in the milligram range would be a groundbreaking achievement as it would demonstrate the ability to create and control large BECs. This could have significant implications for quantum computing, precision measurement, and other areas of research.
Creating a Biggest Bosenova in the milligram range is challenging because it requires precise control and manipulation of a large number of atoms in a BEC. Additionally, the energy released during a Bosenova can cause the BEC to dissipate or collapse, making it difficult to maintain the necessary conditions for a Biggest Bosenova to occur.
Scientists use a variety of techniques, such as laser cooling and evaporative cooling, to create and manipulate BECs. They also use magnetic fields and other methods to control the expansion and energy release during a Bosenova. These techniques are constantly being refined and improved to achieve larger and more stable BECs.
Achieving a Biggest Bosenova in the milligram range could have various applications, such as improving the precision of atomic clocks, creating more accurate sensors, and advancing our understanding of fundamental physics. It could also lead to new technologies in quantum computing and communications.
