Spectroscopy instead of scattering: particle experimentation in AdS spacetime
Oleg Evnin
Particle experiments are difficult at weak coupling because interactions are rare and a huge number of collision attempts are needed to attain significant precision. One often hear…
A Graceful Exit for the Cosmological Constant Damping Scenario
Oleg Evnin, Kévin Nguyen
We present a broad and simple class of scalar-tensor scenarios that successfully realize dynamical damping of the effective cosmological constant, therefore providing a viable dyna…
A nonrelativistic limit for AdS perturbations
Piotr Bizon, Oleg Evnin, Filip Ficek
The familiar nonrelativistic limit converts the Klein-Gordon equation in Minkowski spacetime to the free Schroedinger equation, and the Einstein-massive-scala…
Energy returns in global AdS_4
Anxo Biasi, Ben Craps, Oleg Evnin
Recent studies of the weakly nonlinear dynamics of probe fields in global AdS (and of the nonrelativistic limit of AdS resulting in the Gross-Pitaevskii equation) have revealed…
Melonic Turbulence
Stéphane Dartois, Oleg Evnin, Luca Lionni +2
We propose a new application of random tensor theory to studies of non-linear random flows in many variables. Our focus is on non-linear resonant systems which often emerge as weak…
Quantum resonant systems, integrable and chaotic
Oleg Evnin, Worapat Piensuk
Resonant systems emerge as weakly nonlinear approximations to problems with highly resonant linearized perturbations. Examples include nonlinear Schroedinger equations in harmonic…
