“…These can be first or second order phase transition as a function of the detailed form of the holographic theory. 24 The first attempt towards finding a superconducting dome from holography has been done in the Abelian-Higgs model [18] by introducing a modulating chemical potential [89]. It was shown that there is a critical modulation wave number above which the critical temperature will vanish or nearly vanish.…”

We use a holographic theory to model and study the competition of four phases: an antiferromagnetic phase, a superconducting phase, a metallic phase and a striped phase, using as control parameters temperature and a doping-like parameter. We analyse the various instabilities and determine the possible phases. One class of phase diagrams, that we analyse in detail, is similar to that of high-temperature superconductors as well as other strange metal materials.

“…Introducing a spatially modulated source, such as a periodic chemical potential, can be interpreted as modeling an underlying lattice [8][9][10][11][12][13][14][15][16][17] or disorder [18,19], while a single localized source represents a defect [20][21][22]. Linearly varying scalar fields cause the weakest breaking, yielding a homogeneous stress tensor and allowing a more tractable analysis [23][24][25][26][27][28][29][30][31].…”

Holographic sliding stripes

Holographic models provide unique laboratories to investigate non-linear physics of transport in inhomogeneous systems. We provide a detailed account of both DC and AC conductivities in a defect CFT with spontaneous stripe order. The spatial symmetry is broken at large chemical potential and the resulting ground state is a combination of a spin and charge density wave. An infinitesimal applied electric field across the stripes will cause the stripes to slide over the underlying density of smeared impurities, a phenomenon which can be associated with the Goldstone mode for the spontaneously broken translation symmetry. We show that the presence of a spatially modulated background magnetization current thwarts the expression of some DC conductivities in terms of horizon data.Comment: 37 pages, 8 figures; v2: minor clarifications, published versio

“…tories, R, can de facto be disregarded compared to the P exchange). Setting s 1 ≈ s 2 , M ≈ 1 GeV, and √ s = 7 TeV and using the relation s 1 s 2 ≈ M 2 s (which holds for processes in the central region [192][193][194]), we obtain √ s 1 ≈ √ s 2 ≈ 84 GeV. Thus, the dominance of the PP exchange in LHC experiments is a very good approximation.…”

“…Only resonances with positive C-parity and the isotopic spin I = 0 can be produced in a two-pomeron collision. The cross sections of processes driven by that mechanism do not decrease as a power of energy [24,173,[192][193][194]. Therefore, the observation of resonances in X 0 states with I = 1 is a signal that they are produced or decay with isotopic invariance violation.…”

“…It should be kept in mind that a similar way to check the consistency of the results of measurements for the decays f 1 (1285) → π + π − π 0 and f 1 (1285) → KKπ was discussed in Section 5.2. Formulas relating σ(PP → X 0 ; m) to the experimentally measured cross section of the reaction pp → p(X 0 )p can be found, e.g., in [192][193][194].…”

Siberian Branch of the Russian Academy of Sciences, prosp. Akademika Koptyuga 4, 630090 Novosibirsk, Russian FederationIsospin symmetry breaking is discussed as a tool for studying the nature and production mechanisms of light scalar mesons. We are concerned with isospin breaking effects with an amplitude ∼ √ m d − mu (instead of the usual ∼ m d − mu), where mu and m d are the u and d quark masses, whose magnitude and phase vary with energy in a resonance-like way characteristic of the KK threshold region. We consider a variety of reactions that can experimentally reveal (or have revealed) the mixing of a 0 0 (980) and f0 (980) resonances that breaks the isotopic invariance due to the mass difference between K + and K 0 mesons. Experimental results on the search for a 0 0 (980) − f0(980) mixing in f1(1285) → f0(980)π 0 → π + π − π 0 and η(1405) → f0(980)π 0 → π + π − π 0 decays suggest a broader perspective on the isotopic symmetry breaking effects due to the K + and K 0 mass difference. It has become clear that not only the a 0 0 (980) − f0(980) mixing but also any mechanism producing KK pairs with a definite isospin in an S wave gives rise to such effects, thus suggesting a new tool for studying the nature and production mechanisms of light scalars. Of particular interest is the case of a large isotopic symmetry breaking in the η(1405) → f0(980)π 0 → π + π − π 0 decay due to the occurrence of anomalous Landau thresholds (logarithmic triangle singularities), i.e., due to the η(1405) → (K * K +K * K) → (K + K − + K 0K 0 )π 0 → f0(980)π 0 → π + π − π 0 transition (where it is of fundamental importance that the K * meson has a finite width).
