Possible origin of fermion generations

In the model with the spontaneous breaking of chiral gauge symmetry, the vacuum structure for the pair of Higgs fields can cause the appearance of two generations of fermions. Two generations of fermions, say, electron and muon, have identical properties with respect to a gauge interaction and differ by the mass values yet. In the Standard Model [1] the masses are caused by the spontaneous brea...

Introducing the SARS-CoV-2 and discussing the possible origin of the virus

The emergence of the dangerous and deadly COVID-19 disease in late 2019 in Wuhan, China, and its rapid spread has had a profound global impact on health, mental security, the economy, culture and politics of various countries, drawing the attention of the medical community and related sciences for identification and treatment of this disease. Various studies on the disease have identified a new...

Origin of Jahn-Teller distortion and orbital order in LaMnO3.

The origin of the cooperative Jahn-Teller distortion and orbital order in LaMnO3 is central to the physics of the manganites. The question is complicated by the simultaneous presence of tetragonal and GdFeO3-type distortions and the strong Hund's rule coupling between e{g} and t{2g} electrons. To clarify the situation we calculate the transition temperature for the Kugel-Khomskii superexchange ...

A Possible Origin of Dark Energy

We discuss the possibility that the existence of dark energy may be due to the presence of a spin zero field φ(x), either elementary or composite. In the presence of other matter field, the transformation φ(x) → φ(x) + constant can generate a negative pressure, like the cosmological constant. In this picture, our universe can be thought as a very large bag, similar to the much smaller MIT bag m...
