The quest for a final theory - loop quantum gravity vs superstring theory

A classical solution of a supergravity theory is a bosonic field configuration which satisfies the equations of motion of the theory once the auxiliary fields have been removed and

The acoustic peak in the matter correlation function in linear theory (solid), 1-loop perturbation theory (dashed), and simulation.. seen that the perturbative treatment has

The embedding tensor approach provides a systematic way to study the most general gaugings of a Supergravity theory and is a powerful technique to construct gauged Supergravity

Lacking a detailed theory for non-equilibrium polariton condensates, we test the validity of both atomic theories comparing the behavior of the temperature dependence

As we have seen, even though the addition of a cosmological constant to Einstein’s eld equations may be the simplest way to obtain acceleration, it has its caveats. For this rea-

In other words, different supercritical string theories living in different spacetime dimensions are connected to each other via a process of tachyon condensation.. Tachyon

This non- trivial response of the phase under gauge transformations causes a deformation of the corresponding Lie-algebra commutators and leads to the appearance of central
