“…One is holography which relates theories living in spaces with different dimensionality. In high energy physics, the holography is introduced as the statement: quantum gravity in some region may be described in terms of a non gravitational theory living in its boundary [5]. Another important idea is that the nonabelian gauge theory might have a dual description in terms of strings [6].…”

“…In order to study thermal gauge theories, we may take the imaginary time analysis 5 . We analytically continue to Euclidean spacetime and compactify the time direction with the thermal period 1/T with 4 In [18], it has been shown that the theory develops a mass gap.…”

“…We analytically continue to Euclidean spacetime and compactify the time direction with the thermal period 1/T with 4 In [18], it has been shown that the theory develops a mass gap. In the regime λ 5 1/M KK , the scale of the mass gap is exponentially suppressed compared to M KK . Then the gauge theory is effectively 4D pure Yang-Mills.…”

Abstract. As a part of the attempt to address dense baryonic matter, we first review holographic approaches to QCD. The big advantage of the holographic approaches is that they render strongly coupled 4D gauge theories as duals of certain weakly coupled string/supergravity that are well understood. Its relevance to real QCD is one of the central problems in hadron/nuclear physics as well as in the context of applied string theory. None of the models based on these holographic approaches presently available can adequately describe the system we are interested in, namely dense baryonic matter. Nevertheless, some aspects of the holographic approach are found to describe certain processes both in vacuum and in medium. In this talk we only present the structure of a model that appears to be closest to QCD, and has the potential to address the problem.

“…The center vortex theory of confinement [1][2][3][4][5][6] is motivated by the fact that the asymptotic string tension associated with Wilson loops in group representation r, in a pure SU(N) gauge theory, depends only on the N-ality of that representation, i.e. on the transformation properties of the Wilson loop holonomy with respect to the Z N center subgroup.…”

“…String tensions computed on the center-projected lattice, in SU(2) lattice gauge theory, are known to have excellent scaling properties, and agree fairly well with the asymptotic string tensions computed on the unprojected lattice, a feature known as "center dominance." 1 The excitations on the projected Z N lattice are known as "P-vortices." We define a Pplaquette as a plaquette on the projected lattice whose value is an element of the Z N group different from unity.…”

Scaling properties of Wilson loops pierced by P-vortices

P-vortices, in an SU(N) lattice gauge theory, are excitations on the center-projected Z N lattice. We study the ratio of expectation values of SU(2) Wilson loops, on the unprojected lattice, linked to a single P-vortex, to that of Wilson loops which are not linked to any P-vortices. When these ratios are plotted versus loop area in physical units, for a range of lattice couplings, it is found that the points fall approximately on a single curve, consistent with scaling. We also find that the ratios are rather insensitive to the point where the minimal area of the loop is pierced by the P-vortex.

Physical microscopic free‐choice model in the framework of a Darwinian approach to quantum mechanics

A compatibilistic model of free choice for a fundamental particle is built within a general framework that explores the possibility that quantum mechanics be the emergent result of generalised Darwinian evolution acting on the abstract landscape of possible physical theories. The central element in this approach is a probabilistic classical Turing machine –basically an information processor plus a randomiser– methodologically associated with every fundamental particle. In this scheme every system acts not under a general law, but as a consequence of the command of a particular, evolved algorithm. This evolved programme enables the particle to algorithmically anticipate possible future world configurations in information space, and as a consequence, without altering the natural forward causal order in physical space, to incorporate elements to the decision making procedure that are neither purely random nor strictly in the past, but in a possible future.
