Touring the Hagedorn ridge

  title={Touring the Hagedorn ridge},

  journal={arXiv: High Energy Physics - Theory},
We review aspects of the Hagedorn regime in critical string theories, from basic facts about the ideal gas approximation to the proposal of a global picture inspired by general ideas of holography. It was suggested that the condensation of thermal winding modes triggers a first-order phase transition. We propose, by an Euclidean analogue of the string/black hole correspondence principle, that the transition is actually related to a topology change in spacetime. Similar phase transitions induced… 

Deconstructing the Little Hagedorn holography

We study aspects of the thermodynamics of Little String Theory, using its geometrical definition in critical ten‐dimensional string theory. We find that bulk radiation effects tend to screen the

Fine structure of Hagedorn transitions

We study non-perturbative aspects of the Hagedorn transition for IIB string theory in an anti-de Sitter spacetime in the limit that the string length goes to infinity. The theory has a holographic

Random walks and the Hagedorn transition

We study details of the approach to the Hagedorn temperature in string theory in various static spacetime backgrounds. We show that the partition function for a single string at finite temperature is

Hagedorn divergences and tachyon potential

We consider the critical behavior for a string theory near the Hagedorn temperature. We use the factorization of the worldsheet to isolate the Hagedorn divergences at all genera. We show that the

Random walks in Rindler spacetime and string theory at the tip of the cigar

In this paper, we discuss Rindler space string thermodynamics from a thermal scalar point of view as an explicit example of the results obtained in [1]. We discuss the critical behavior of the string

Effective field theory for closed strings near the Hagedorn temperature

We discuss interacting, closed, bosonic and superstrings in thermal equilibrium at temperatures close to the Hagedorn temperature in flat space. We calculate S-matrix elements of the strings at the

Random walks in Rindler spacetime and string theory at the tip of the cigar

A bstractIn this paper, we discuss Rindler space string thermodynamics from a thermal scalar point of view as an explicit example of the results obtained in [1]. We discuss the critical behavior of

Can the Hagedorn phase transition be explained from matrix model for strings

The partition function of BFSS matrix model is studied for two different classical backgrounds up to 1-loop level. One of the backgrounds correspond to a membrane wrapped around a compact direction

Near-Hagedorn thermodynamics and random walks — extensions and examples

This paper elaborate on the random walk picture in these spacetimes and how it is modified and analyzes a previously studied toroidally compactified background where the Hagedorn temperature is determined and a flat space orbifold model.



Thermal Duality Confronts Entropy: A New Approach to String Thermodynamics?

One of the most intriguing features of string thermodynamics is thermal duality, which relates the physics at temperature T to the physics at inverse temperature 1/T. Unfortunately, the traditional

Topology change in general relativity, and the black-hole black-string transition

In the presence of compact dimensions massive solutions of General Relativity may take one of several forms including the black-hole and the black-string, the simplest relevant background being 3+1 ×

Thermal Duality and the Canonical String Ensemble

We give a first principles formulation of equilibrium string thermodynamics in the canonical ensemble, compatible with the Euclidean timelike T-duality transformations that link the six

Localized Tachyons and RG Flows

We study condensation of closed string tachyons living on defects, such as orbifold fixed planes and Neveu-Schwarz fivebranes. We argue that the high energy density of localized states decreases in

A Critique of Pure String Theory: Heterodox Opinions of Diverse Dimensions

I present a point of view about what M Theory is and how it is related to the real world that departs in certain crucial respects from conventional wisdom. I argue against the possibility of a

Black-hole–black-string phase transitions in thermal (1 + 1)-dimensional supersymmetric Yang–Mills theory on a circle

We review and extend earlier work that uses the AdS/CFT correspondence to relate the black-hole–black-string transition of gravitational theories on a circle to a phase transition in maximally

Dimensional Reduction in Quantum Gravity

The requirement that physical phenomena associated with gravitational collapse should be duly reconciled with the postulates of quantum mechanics implies that at a Planckian scale our world is not

Non-BPS States and Branes in String Theory

We review the recent developments in our understanding of non-BPS states and branes in string theory. The topics include 1) construction of unstable non-BPS D-branes in type IIA and type IIB string
