Black Holes and Five-brane Thermodynamics [PDF]

open access: yes, 1999
The phase diagram for Dp-branes in M-theory compactified on $T^4$, $T^4/Z_2$, $T^5$, and $T^6$ is constructed. As for the lower-dimensional tori considered in our previous work (hep-th/9810224), the black brane phase at high entropy connects onto matrix ...

Do charged-pions condense in a magnetic field with rotation?

open access: yesJournal of High Energy Physics
We revisit the condensation scenario of charged pions in external magnetic field and rotation, which was first considered by Y. Liu and I. Zahed. Based on the Ginzburg-Landau analysis of the Nambu-Jona-Lasinio model, we find that the charged-pion ...

Ground State Phase Diagram of Generic XY Pyrochlore Magnets with Quantum Fluctuations

open access: yes, 2013
Motivated by recent experimental and theoretical progress on the Er2Ti2O7 pyrochlore XY antiferromagnet, we study the problem of quantum order-by-disorder in pyrochlore XY systems. We consider the most general nearest-neighbor pseudo spin-1/2 Hamiltonian

Dynamic critical behavior of the chiral phase transition from the real-time functional renormalization group

open access: yesJournal of High Energy Physics
The collective dynamics around the second-order O(4) chiral phase transition in QCD with two massless quark flavors can be understood by appealing to universality.

Thermodynamics from the S-matrix reloaded, with applications to QCD and the confining Flux Tube

open access: yesJournal of High Energy Physics
Over the past decade and more, S-matrix-based calculational methods have experienced a resurgence, proving to be both an elegant and powerful tool for extracting physical quantities without the need for an underlying Lagrangian formulation. In this work,

Baryogenesis and first-order QCD transition with gravitational waves from a large lepton asymmetry

open access: yesJournal of High Energy Physics
A large primordial lepton asymmetry can lead to successful baryogenesis by preventing the restoration of electroweak symmetry at high temperatures, thereby suppressing the sphaleron rate.

Metal-insulator transition in a weakly interacting many-electron system with localized single-particle states

open access: yes, 2005
We consider low-temperature behavior of weakly interacting electrons in disordered conductors in the regime when all single-particle eigenstates are localized by the quenched disorder.

The underlying black hole phase transitions in an Einstein-Maxwell-dilaton model with a holographic critical point

open access: yesJournal of High Energy Physics
The Einstein-Maxwell-dilaton model exhibits a first-order phase transition curve that terminates at a holographic critical endpoint, offering intriguing insights into the phase diagram of the dual system living on the boundary.

Cosmological evolution of a complex scalar field with repulsive or attractive self-interaction

open access: yes, 2017
We study the cosmological evolution of a complex scalar field with a self-interaction potential $V(|\varphi|^2)$, possibly describing self-gravitating Bose-Einstein condensates, using a fully general relativistic treatment. We generalize the hydrodynamic

The imprint of conservation laws on correlated particle production

open access: yesJournal of High Energy Physics
The study of event-by-event fluctuations of net-baryon number in a subspace of full phase space is a promising direction for deciphering the structure of strongly interacting matter created in collisions of relativistic heavy nuclei.
