Earliest twenty-seventh named storm. Caused damage in the Southeast United States. Brought snow to New England.
Earliest twenty-eight named storm. Became a powerful Category 4 hurricane. Struck Central America, Cuba, and Florida.
On November 10, Subtropical Storm Theta formed, making the 2020 Atlantic hurricane season the busiest Atlantic hurricane season on record. The next day, the storm transitioned into a tropical storm, as it peaked with winds of 70 mph (110 km/h). The storm then weakened, but restrengthened to reach 65 mph (105 km/h), before weakening, and eventually dissipating on July 15.
Hurricane Iota was a deadly and damaging storm that hit Central America on November 17. Forming in the Caribbean Sea, the storm strengthened a lot rapidly, becoming one of the latest Category 4 storms to form, reaching Category 4 status on November 16.
This is a table of all the storms that have formed in the 2020 Atlantic hurricane season. It includes their duration, names, landfall(s), denoted in parentheses, damages, and death totals. Deaths in parentheses are additional and indirect (an example of an indirect death would be a traffic accident), but were still related to that storm. Damage and deaths include totals while the storm was extratropical, a tropical wave, or a low, and all the damage figures are in USD. Potential tropical cyclones are not included in this table.
Majorana fermion
A Majorana fermion(), also referred to as a Majorana particle, is a fermion that has the same properties as its antiparticle. Ettore Majorana, an Italian physicist, thought they would exist, in 1937. Majorana disappeared in 1938, and the particles are named after him. As Majorana fermionns are thought to have the same properties as their antiparticles, they cannot have an electric charge. Today, atomic particles with an electric charge are called Dirac fermions. An example for Dirac fermions are electrons, and positrons; they have the same properties, but their electric charge is different.
Neutrinos do not have an electric charge, and might be Majorana fermions, but their status is unclear
The concept goes back to Majorana's suggestion of 1937. Majorana suggested that neutral spin- particles can be described by a real wave equation (the Majorana equation). The wave functions of particle and antiparticle are related by complex conjugation. For this reason, they would be identical to their antiparticle.
The difference between Majorana fermions and Dirac fermions can be expressed mathematically in terms of the creation and annihilation operators of second quantization: The creation operator formula_1 creates a fermion in quantum state formula_2 (described by a "real" wave function), whereas the annihilation operator formula_3 annihilates it (or, equivalently, creates the corresponding antiparticle). For a Dirac fermion the operators formula_1 and formula_3 are distinct, whereas for a Majorana fermion they are identical. The ordinary fermionic annihilation and creation operators formula_6 and formula_7 can be written in terms of two Majorana operators formula_8 and formula_9 by
In supersymmetry models, neutralinos—superpartners of gauge bosons and Higgs bosons—are Majorana.
The standard model of physics has no Majorana fermions, all particles are Dirac fermions. There are neutrinos, and anti-neutrinos. In the standard model, neutrinos have no mass, though. The question how to differentiate between neutrinos and anti-neutrinos is not settled yet.
There are different extensions of the standard model. One of them is called Minimal Supersymmetric Standard Model. It allows for supersymmetry, and can transform one kind of particle, the bosons, into the other, the fermions. In condensed matter physics, bound Majorana fermions can appear as quasiparticle excitations—the collective movement of several individual particles, not a single one, and they are governed by non-abelian statistics.
