Latent heat in the chiral phase transition
نویسنده
چکیده
A many-particle system in general possesses two or more different forms of existence called phases. Conversions between these phases are called phase transitions. There are mainly two kinds of phase transitions. One is the first-order phase transition, the other is the secondorder one. In the first-order phase transition, as in the conversion from vapor to liquid, the entropy of the system changes discontinuously and a certain amount of heat may be generated as a result. This kind of heat has been called latent heat since named by Joseph Black (17281799). On the other hand, in the second-order phase transition, the entropy changes continuously and the latent heat is not given off.

Chiral phase transition from string theory.
The low energy dynamics of a certain D-brane configuration in string theory is described at weak t'Hooft coupling by a nonlocal version of the Nambu-Jona-Lasinio model. We study this system at finite temperature and strong t'Hooft coupling, using the string theory dual. We show that for sufficiently low temperatures chiral symmetry is broken, while for temperatures larger then the critical valu...

High-resolution calorimetry has been used to determine the heat capacity and latent heat associated with phase transitions in the homologous series of chiral liquid crystals nF2BTFOIM7 (3-fluoro-4(1-methylheptyloxy)4'-(4"-alkoxy-2",3"-difluorobenzoyloxy)tolane]. These compounds exhibit smectic-C* (SmC*), twist-grain-boundary (TGBA for n = 10, TGBC for n = ii, 12) and cholesteric (N*) phases. Al...

Abstract Energy crisis is a major challenge in the current world. Latent heat thermal energy storage (LHTES) systems are known as equipment with promising performance by which thermal energy can be recovered. In the present study a comprehensive theoretical and experimental investigation is performed on a LHTES system containing PEG1000 as phase change material (PCM). Discussed topics can be ca...
متن کاملReheating after Supercooling in the Chiral Phase Transition
We study the conversion of the latent heat of a supercooled quark-gluon plasma into excitations of the pion field. Supercooling is predicted to occur in the late stages of the evolution of a quark-gluon plasma produced in energetic heavy-ion collisions, if the QCD phase transition is of first order. The supercooled, chirally symmetric state, which contains potential energy associated with an en...
متن کاملTwist-grain-boundary transitions in a chiral tolane compound
High resolution calorimetric studies have been carried out on the chiral compound methylheptyloxydi ̄ uorooctyloxybenzoyloxytolane (8BTF2O1M7 ). The tilt tendency is greater in this compound than in several other structurally similar ̄ uorinated tolane liquid crystals, and it exhibits tilted chiral smectic C (SmC*) and tilted twist-grain-boundary (TGBC) phases but not the untilted SmA or TGBA pha...
