Improved decay estimates and -asymptotic stability of solutions to the Einstein-scalar field system in spherical symmetry
João L. Costa, Rodrigo Duarte, Filipe C. Mena
We investigate the asymptotic stability of solutions to the characteristic initial value problem for the Einstein (massless) scalar field system with a positive cosmological consta…
Spectral and steady-state properties of fermionic random quadratic Liouvillians
João Costa, Pedro Ribeiro, Andrea de Luca +2
We study spectral and steady-state properties of generic Markovian dissipative systems described by quadratic fermionic Liouvillian operators of the Lindblad form. The Hamiltonian…
Semilinear wave equations on accelerated expanding FLRW spacetimes
João L. Costa, Anne T. Franzen, Jesús Oliver
We identify a large class of systems of semilinear wave equations, on fixed accelerated expanding FLRW spacetimes, with nearly at spatial slices, for which we prove small data futu…
