AdS boson stars in string theory
Alex Buchel
Boson stars are stationary soliton-like gravitational configurations supported by a complex scalar field charged under the global symmetry. We discuss properties of boson st…
Universality of small black hole instability in AdS/CFT
Alex Buchel
type IIb supergravity compactifications on five-dimensional Einstein manifolds realize holographic duals to four-dimensional conformal field theories. Black ho…
On stability of nonthermal states in strongly coupled gauge theories
Alex Buchel, Michael Buchel
Low-energy thermal equilibrium states of strongly coupled supersymmetric Yang-Mills (SYM) theory on a three-sphere are unstable with respect to fluctuations breaking t…
Universal relaxation in quark-gluon plasma at strong coupling
Alex Buchel, Andrew Day
We use top-down gauge theory/string theory correspondence to compute relaxation rates in strongly coupled nonconformal gauge theory plasma. We compare models with difference mechan…
Equilibration rates in a strongly coupled nonconformal quark-gluon plasma
Alex Buchel, Michal P. Heller, Robert C. Myers
We initiate the study of equilibration rates of strongly coupled quark-gluon plasmas in the absence of conformal symmetry. We primarily consider a supersymmetric mass deformation w…
Small black holes in
Alex Buchel, Luis Lehner
We consider small black holes in , smeared on . We compute the spectrum of -quasinormal modes corresponding to fluctuations leading to…
Black hole spectra in holography: consequences for equilibration of dual gauge theories
Alex Buchel
For a closed system to equilibrate from a given initial condition there must exist an equilibrium state with the energy equal to the initial one. Equilibrium states of a strongly c…
