The necessity of dark matter in MOND within galactic scales
Ignacio Ferreras, Mairi Sakellariadou, Muhammad Furqaan Yusaf
To further test MOdified Newtonian Dynamics (MOND) on galactic scales -- originally proposed to explain the rotation curves of disk galaxies without dark matter -- we study a sampl…
On the possibility of Dark Energy from corrections to the Wheeler-De Witt equation
William Nelson, Mairi Sakellariadou
We present a method for approximating the effective consequence of generic quantum gravity corrections to the Wheeler-DeWitt equation. We show that in many cases these corrections…
Lattice Refining LQC and the Matter Hamiltonian
William Nelson, Mairi Sakellariadou
In the context of loop quantum cosmology, we parametrise the lattice refinement by a parameter, , and the matter Hamiltonian by a parameter, . We then solve the Hamiltonian c…
Lattice Refining Loop Quantum Cosmology and Inflation
William Nelson, Mairi Sakellariadou
We study the importance of lattice refinement in achieving a successful inflationary era. We solve, in the continuum limit, the second order difference equation governing the quant…
Numerical experiments with p F- and q D-strings: the formation of (p,q) bound states
Arttu Rajantie, Mairi Sakellariadou, Horace Stoica
We investigate the behaviour of (p,q) string networks, focusing on two aspects: (1) modelling more realistic (p,q) string networks than the Z_N networks used so far and (2) investi…
Relativistic Modified Newtonian Dynamics from String Theory?
Nick Mavromatos, Mairi Sakellariadou
We argue that TeVeS-like vector fields appear naturally in certain string theory backgrounds involving D0-branes, as a result of the recoil velocity field, expressing the interacti…
