Galaxy clusters and structure formation in quintessence versus phantom dark energy universe
Zacharias Roupas, Minos Axenides, George Georgiou +1
The self-gravitating gas in the Newtonian limit is studied in the presence of dark energy with a linear and constant equation of state. Entropy extremization associates to the isot…
Large-Spin Expansions of GKP Strings
Emmanuel Floratos, George Georgiou, Georgios Linardopoulos
We demonstrate that the large-spin expansion of the energy of Gubser-Klebanov-Polyakov (GKP) strings that rotate in RxS2 and AdS3 can be expressed in terms of Lambert's W-function.…
Generalised cusp anomalous dimension in beta-deformed super Yang Mills theory
George Georgiou, Dimitrios Giataganas
In this work we study the cusp anomalous dimension of the marginally deformed N=4 sYM theory. We find the expression of the cusp anomalous dimension both at the weak and strong cou…
Gravothermal instability with a cosmological constant in the canonical ensemble
Minos Axenides, George Georgiou, Zacharias Roupas
We present here how the gravothermal or Antonov's instability, which was originally formulated in the microcanonical ensemble, is modified in the presence of a cosmological constan…
Gravitational instabilities of isothermal spheres in the presence of a cosmological constant
Minos Axenides, George Georgiou, Zacharias Roupas
Gravitational instabilities of isothermal spheres are studied in the presence of a positive or negative cosmological constant, in the Newtonian limit. In gravity, the statistical e…
Correlators of massive string states with conserved currents
George Georgiou, Bum-Hoon Lee, Chanyong Park
We calculate correlation functions of the R-current or the stress-energy tensor T_{μν} with two non-protected operators dual to generic massive string states with rotation in S^5,…
