We investigate the Teukolsky equations in horizon-penetrating coordinates to study the behavior of perturbation waves crossing the outer horizon. For this purpose, we use the null ingoing/outgoing Eddington-Finkelstein coordinates. We find that the radial equation is a confluent form of Heun’s differential equation in both ingoing/outgoing coordinates, with three singularities. The radial...

I put forward a novel variation method for calculating the mass and PDF of hadrons in 1+1D models. The template functions in our method minimize a Free Energy functional composed of free partons kinetic energy and Renyi entropy of all pairs of partons. Our results suggest hadrons in these models minimize this Free Energy functional. I will comment on extending our calculation to confining...

Primordial black holes (PBHs) within the mass range $10^{17} - 10^{22}$ g are a favorable candidate for describing all of the dark matter content. Towards the lower end of this mass range, the Hawking temperature, $T_H$, of these PBHs is $T_H > 100$ keV, allowing for the creation of electron-positron pairs, thus making their Hawking radiation a useful constraint for most current and future...

In canonical quantum mechanics (QM), energy eigenstates can be thought of as evolving in the phase space of a classical harmonic oscillator. Nambu quantum mechanics is a particular generalization of canonical QM whereby this phase space is extended to that of an asymmetric top, introducing two “deformation parameters”. Canonical QM can then be interpreted as the limiting case where both of...

The Randall-Sundrum model has been a great source of interest to theorists

and phenomenologists for over two decades, both for its novel solution to the hierarchy problem, and its phenomenological consequences. The modulus field associated with the warped extra dimension of this model requires stabilization. In this talk I will present ongoing work to investigate the feasibility of...

We analyze the UV breakdown of sub-GeV Dark Matter Models that live in a new, dark U(1) sector. Many of these models include a scalar field, which is either the Dark Matter itself or a dark Higgs field that generates mass terms for the Dark Matter particle via Spontaneous Symmetry Breaking. A quartic self coupling of this scalar field is generically allowed, and we show that its running is...
