Universal analytic dependence of the stress-energy tensor at thermodynamic equilibrium in curved space-time
F. Becattini, F. Palli
The mean value of the stress-energy tensor of a given quantum field theory at global thermodynamic equilibrium in a curved space-time can be expressed in terms of the derivatives o…
Entanglement C-functions of defects and interfaces in supersymmetric Yang-Mills theory
Niko Jokela, Jani Kastikainen, José Manuel Penín +2
We consider planar codimension-one defects and interfaces in supersymmetric Yang-Mills (SYM) theory, realized by the D3/D5-brane intersection. Working in the probe…
Vacuum configuration of winding superstrings from non-standard semiclassical quantization
Tommaso Canneti, Federico Castellani, Wolfgang Mück
Semiclassical quantization techniques are unreliable, if the magnitude of the quantum fluctuations becomes comparable with a classical background scale. This is the case, for examp…
Thermal response of the Nieh-Yan term
Carlos Hoyos, Niko Jokela, José Manuel Penin
We reinterpret the Nieh-Yan (NY) anomaly using holography, finding that the U(1) axial symmetry remains unbroken and the axial current coupling to an external gauge field is conser…
Holographic Hagedorn Temperature: Strong Coupling, Flavor and -angle Effects
Francesco Bigazzi, Tommaso Canneti, Aldo L. Cotrone +1
We study the Hagedorn temperature of strongly coupled quantum field theories admitting a holographic string or M-theory description in various regimes and scenarios. In the f…
Hagedorn temperature in holography: world-sheet and effective approaches
Francesco Bigazzi, Tommaso Canneti, Federico Castellani +2
We provide general results on the Hagedorn temperature of planar, strongly coupled confining gauge theories holographically dual to type II superstring models on curved backgrounds…
