Biggest Bosenova: Milligram Range Feasible?

In summary, the conversation revolved around the topic of bosenovas and their potential size in the milligrams range. The speaker was curious about the technical feasibility of achieving such a size and the largest size observed in the laboratory so far. However, the expert summarizer stated that there is no upper limit to the size of bosenovas, as it depends on technical capabilities. The largest observed size is estimated to be in the 106-107 range, but the expert also mentioned that bosenovas are not considered scientifically interesting and there is no current effort to create larger ones.

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

While I don't know the answer to your questions, others might wonder what a bosenova is:

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.)

It was the reason I posted this question to "Quantum Physics" but it was moved to "General Physics". Any question related to BEC apparently belongs to "Quantum Physics".. anyway thx...

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.

Thanks for the answer ... does it mean that in your opinion to get into milligrams range is technically feasible? My question was not about if it is possible in principle; my question is - if it is technically feasible... What the biggest size Bosenova has been observed in the laboratory so far? Pls provide the link to the source... Thx...

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.

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.

>"Scientifically, bosenovas are not that interesting..."

From what I read about bosenova, there are still some unanswered intriguing observations... anyway, probably because I do not claim to be a scientist it is interesting for me... ;o)

Thx...
 

FAQ: Biggest Bosenova: Milligram Range Feasible?

What is a Bosenova?

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".

What is the significance of a Biggest Bosenova in the milligram range?

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.

Why is it difficult to achieve a Biggest Bosenova in the milligram range?

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.

What techniques are used to achieve a Biggest Bosenova in the milligram range?

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.

What are the potential applications of a Biggest Bosenova in the milligram range?

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.
