| 1 | On Thermodynamics of AdS Black Holes in Arbitrary Dimensions显示文摘Considering the cosmological constantΛas a thermodynamic pressure and its conjugate quantity as a thermodynamic volume as proposed by Kubiznak and Mann[J.High Energy Phys.1207(2012)033],we discuss the critical behavior of charged AdS black hole in arbitrary dimensions d.In particular,we present a comparative study in terms of the spacetime dimension d and the displacement of critical points controlling the transition between the small and the large black holes.Such behaviors vary nicely in terms of d.Our result shows that the equation of state for a charged Reissner–Nordstrom AdS black hole predicts an universal number given by(2d-5)/(4d-8).The three-dimensional solution is also discussed. | A.Belhaj M.Chabab El Moumni M.B.Sedra | 2012 | Chinese Physics Letters2012，29，10： | 1 |
| 2 | Qubit Systems from Colored Toric Geometry and Hypercube Graph Theory显示文摘We develop a new geometric approach to deal with qubit information systems using colored graph theory.More precisely, we present a one to one correspondence between graph theory, and qubit systems, which may be explored to attack qubit information problems using toric geometry considered as a powerful tool to understand modern physics including string theory. Concretely, we examine in some details the cases of one, two, and three qubits, and we find that they are associated with CP^1, CP^1× CP^1 and CP^1× CP^1× CP^1 toric varieties respectively. Using a geometric procedure referred to as a colored toric geometry, we show that the qubit physics can be converted into a scenario handling toric data of such manifolds by help of hypercube graph theory. Operations on toric information can produce universal quantum gates. | Y.Aadel A.Belhaj M.Bensed Z.Benslimane M.B.Sedra A.Segui | 2017 | Communications in Theoretical Physics2017，67，9： | 1 |
| 3 | The Thermodynamical Behaviors of Kerr–Newman AdS Black Holes显示文摘We reconsider the study of critical behaviors of Kerr—Newman Anti-de Sitter(AdS)black holes in four dimensions.The study is made in terms of the moduli space parameterized by the charge Q and the rotation parameter a,relating the mass M of the black hole and its angular momentum J via the relation a=J/M.Specifically,we discuss such thermodynamical behaviors in the presence of a positive cosmological constant considered as a thermodynamic pressure and its conjugate quantity as a thermodynamic volume.The equation of state for a charged Reissner—Nordstrom AdS black hole predicts a critical universal number depending on the(Q,a)moduli space.In the vanishing limit of the a parameter,this prediction recovers the usual universal number in four dimensions.Then,we find the bounded region of the moduli space allowing the consistency of the model with real thermodynamical variables. | A.Belhaj M.Chabab H.El Moumni L.Medari M.B.Sedra | 2013 | Chinese Physics Letters2013，30，9： | 0 |
