Integrability on the master space

Abstract

It has been recently shown that every SCFT living on D3 branes at a toric Calabi-Yau singularity surprisingly also describes a complete integrable system. In this paper we use the Master Space as a bridge between the integrable system and the underlying field theory and we reinterpret the Poisson manifold of the integrable system in term of the geometry of the field theory moduli space.

Electromagnetic properties of viscous charged fluids

“…In Ref. [20], the existence of multiple electromagnetic waves with the same frequency was addressed. In Ref.…”

Electromagnetic response of strongly coupled plasmas

“…In the present paper we investigated the electromagnetic linear response of the neutral plasma beyond the hydrodynamical regime and we have proven that globally neutral, strongly coupled plasmas can support modes with negative refraction too. Moreover, in [25], the presence of multiple electromagnetic modes was shown to be generic for the hydrodynamical regime of charged plasmas. Here we perform a similar analysis which however entails the non-hydrodynamical modes of the neutral plasma.…”

“…Inspired by the amazing developments obtained on metamaterials, in [23][24][25] it was first discovered that charged fluids which admit a hydrodynamical description present exotic electromagnetic properties as a general feature. The negative refraction phenomenon (in a certain range of frequencies) and the presence of additional light-waves are shown respectively in [23,24] and [25].…”

“…Inspired by the amazing developments obtained on metamaterials, in [23][24][25] it was first discovered that charged fluids which admit a hydrodynamical description present exotic electromagnetic properties as a general feature. The negative refraction phenomenon (in a certain range of frequencies) and the presence of additional light-waves are shown respectively in [23,24] and [25]. The former implies that the electromagnetic energy flux and the phase velocity of an electromagnetic wave through the medium propagate in opposite directions [6,[12][13][14][15][16][17][18][19][20][21][22]; the latter means that, even if isotropic, a medium supports multiple electromagnetic waves with the same frequency but different wave-vectors [7][8][9][10][11].…”

Refractive index of light and the quark-gluon plasma

“…[12][13][14][15]. Furthermore, it was proven to be a possible generic phenomenon in charged hydrodynamical systems and the non-magnetizable QGP [16]. The NRI is a very exotic electromagnetic phenomenon of materials, in which the phase velocity of the light propagating in it is in the opposite direction to the energy flow.…”
