Thermodynamic topology of black holes and an invariant of spacetime
Cao H. Nam
We present a formalism for exploring the thermodynamic topology of black holes, without introducing the auxiliary variable employed in previous studies. The formalism i…
Prediction of non-SUSY AdS conjecture on the lightest neutrino mass revisited

We study the constraint of the non-SUSY AdS conjecture on the three-dimensional vacua obtained from the compactification of the Standard Model coupled to Einstein gravity on a circ…

Cao H. Nam
We aim to provide a microscopic explanation of observed 4D black holes based on the compactification of 5D Einstein gravity plus a positive cosmological constant on a circle. The f…

Cao H. Nam
In order for string theory to be made compatible with the low-energy observations of a positive cosmological constant, there have been attempts to construct dS vacua in string theo…
Probing dark gauge boson via Einstein-Cartan portal
Cao H. Nam
Einstein-Cartan gravity which is an alternative formulation of general relativity introduces new degrees of freedom contained in the torsion field which encodes the torsion feature…
Holographic model with power-law Maxwell field for color superconductivity
Cao H. Nam
Studying the color superconductivity (CSC) phase is essential to understand the physics in the core of the neutron stars which is the only known context where the CSC phase might a…
