Tetrads and q-theory

Understand

As the microscopic structure of the deep relativistic quantum vacuum is unknown, a phenomenological approach ($q$-theory) has been proposed to describe the vacuum degrees of freedom and the dynamics of the vacuum energy after the Big Bang.

• The original $q$-theory was based on a four-form field strength from a three-form gauge potential.
• However, this realization of $q$-theory, just as others suggested so far, is rather artificial and does not take into account the fermionic nature of the vacuum.
• We now propose a more physical realization of the $q$-variable.
