A dynamical inflaton coupled to strongly interacting matter
Christian Ecker, Elias Kiritsis, Wilke van der Schee
According to the inflationary theory of cosmology, most elementary particles in the current universe were created during a period of reheating after inflation. In this work we self…
Holographic Evolution with Dynamical Boundary Gravity
Christian Ecker, Wilke van der Schee, David Mateos +1
Holography has provided valuable insights into the time evolution of strongly coupled gauge theories in a fixed spacetime. However, this framework is insufficient if this spacetime…
Saturation of the Quantum Null Energy Condition in Far-From-Equilibrium Systems
Christian Ecker, Daniel Grumiller, Wilke van der Schee +1
The Quantum Null Energy Condition (QNEC) is a new local energy condition that a general Quantum Field Theory (QFT) is believed to satisfy, relating the classical null energy condit…
Exploring nonlocal observables in shock wave collisions
Christian Ecker, Daniel Grumiller, Philipp Stanzer +2
We study the time evolution of 2-point functions and entanglement entropy in strongly anisotropic, inhomogeneous and time-dependent N=4 super Yang-Mills theory in the large N and l…
Coupling constant corrections in a holographic model of heavy ion collisions
Sašo Grozdanov, Wilke van der Schee
We initiate a holographic study of coupling-dependent heavy ion collisions by analysing for the first time the effects of leading-order, inverse coupling constant corrections. In t…
Holographic heavy ion collisions with baryon charge
Jorge Casalderrey-Solana, David Mateos, Wilke van der Schee +1
We numerically simulate collisions of charged shockwaves in Einstein-Maxwell theory in anti-de Sitter space as a toy model of heavy ion collisions with non-zero baryon charge. The…
A new dynamical instability in Anti-de-Sitter spacetime
Umut Gürsoy, Aron Jansen, Wilke van der Schee
We present fully dynamical solutions to Einstein-scalar theory in asymptotically Anti-de-Sitter spacetime with a scalar potential containing particularly rich physics. Depending on…
Weak and strong coupling equilibration in nonabelian gauge theories
Liam Keegan, Aleksi Kurkela, Paul Romatschke +2
We present a direct comparison studying equilibration through kinetic theory at weak coupling and through holography at strong coupling in the same set-up. The set-up starts with a…
Universal hydrodynamic flow in holographic planar shock collisions
Paul M. Chesler, Niki Kilbertus, Wilke van der Schee
We study the collision of planar shock waves in AdS as a function of shock profile. In the dual field theory the shock waves describe planar sheets of energy whose collision re…
Complexified boost invariance and holographic heavy ion collisions
Steven S. Gubser, Wilke van der Schee
At strong coupling holographic studies have shown that heavy ion collisions do not obey normal boost invariance. Here we study a modified boost invariance through a complex shift i…
Absence of a local rest frame in far from equilibrium quantum matter
Peter Arnold, Paul Romatschke, Wilke van der Schee
In a collision of strongly coupled quantum matter we find that the dynamics of the collision produces regions where a local rest frame cannot be defined because the energy-momentum…
Gravitational collisions and the quark-gluon plasma
Wilke van der Schee
This thesis addresses the thermalisation of heavy-ion collisions within the context of the AdS/CFT duality. The first part clarifies the numerical set-up and studies the relaxation…
Longitudinal Coherence in a Holographic Model of p-Pb Collisions
Jorge Casalderrey-Solana, Michal P. Heller, David Mateos +1
As a model of the longitudinal structure in heavy ion collisions, we simulate gravitational shock wave collisions in anti-de Sitter space in which each shock is composed of multipl…
From full stopping to transparency in a holographic model of heavy ion collisions
Jorge Casalderrey-Solana, Michal P. Heller, David Mateos +1
We numerically simulate planar shock wave collisions in anti-de Sitter space as a model for heavy ion collisions of large nuclei. We uncover a cross-over between two different dyna…
Holographic isotropization linearized
Michal P. Heller, David Mateos, Wilke van der Schee +1
The holographic isotropization of a highly anisotropic, homogeneous, strongly coupled, non-Abelian plasma was simplified in arXiv:1202.0981 by linearizing Einstein's equations arou…
Strong coupling isotropization of non-Abelian plasmas simplified
Michal P. Heller, David Mateos, Wilke van der Schee +1
We study the isotropization of a homogeneous, strongly coupled, non-Abelian plasma by means of its gravity dual. We compare the time evolution of a large number of initially anisot…
