Sound waves in strongly coupled non-conformal gauge theory plasma
Using gauge theory/gravity duality we study sound wave propagation in strongly coupled non-conformal gauge theory plasma. We compute the speed of sound and the bulk viscosity of N = 2∗ supersymmetric SU(Nc) Yang-Mills plasma at a temperature much larger than the mass scale of the theory in the limit of large Nc and large ’t Hooft coupling. The speed of sound is computed both from the equation o...
متن کاملBlack hole thermodynamics from calculations in strongly coupled gauge theory.
We develop an approximation scheme for the quantum mechanics of N D0-branes at finite temperature in the 't Hooft large- N limit. The entropy of the quantum mechanics calculated using this approximation agrees well with the Bekenstein-Hawking entropy of a ten-dimensional nonextremal black hole with 0-brane charge. This result is in accordance with the duality conjectured by Itzhaki, Maldacena, ...
متن کاملSupersymmetry and Strongly Coupled Gauge Theories
Unlike many of the other talks at this symposium, this one will not take supersymmetry “seriously”: instead of being concerned with how or if supersymmetry enters physics beyond the Standard Model, this talk will treat supersymmetry merely as a technical tool to shed light on the strong coupling behavior of gauge field theories in general. Supersymmetric field theories are especially simple and...
متن کاملStrongly coupled quantum field theory
We analyze numerically a two-dimensional λφ theory showing that in the limit of a strong coupling λ → ∞ just the homogeneous solutions for time evolution are relevant in agreement with the duality principle in perturbation theory as presented in [M.Frasca, Phys. Rev. A 58, 3439 (1998)], being negligible the contribution of the spatial varying parts of the dynamical equations. A consequence is t...
متن کاملStrongly coupled lattice gauge theory with dynamical fermion mass generation in three dimensions
We investigate the critical behaviour of a three-dimensional lattice χUφ3 model in the chiral limit. The model consists of a staggered fermion field, a U(1) gauge field (with coupling parameter β) and a complex scalar field (with hopping parameter κ). Two different methods are used: 1) fits of the chiral condensate and the mass of the neutral unconfined composite fermion to an equation of state...
