Past and Ongoing projects

A New Horizon in the Randall-Sundrum Phase Transition

We explore inflating solutions and dynamic cosmologies in Randall-Sundrum geometries in the presence of a Rindler Horizon in the bulk

Saturation effects in Ultra-peripheral collisions at the LHC

We perform fits to data of electron-proton and proton-heavy ion collisions from HERA and the LHC using versions of the color Dipole model with and without saturation effects

Simulating Open Quantum Systems

We come up with, and implement algorithms to simulate Open Quantum Systems such as Field theories at complex couplings

Smallest eigenvalue density and entanglement

We obtain exact expressions for the smallest eigenvalue density of a Wishart-Laguerre ensemble, and apply it to study entanglement in Coupled Kicked tops
