Generalized pulsating strings
In this paper we consider new solutions for pulsating strings. For this purpose we use the idea of the generalized ansatz for folded and circular strings in hep-th/0311004. We find the solutions to the resulting Neumann-Rosochatius integralbe system and the corrections to the energy. To do that we use the approach developed by Minahan in hep-th/0209047 and find that the corrections are quite di...
متن کاملGeometric entropy of nonrelativistic fermions and two-dimensional strings.
We consider the geometric entropy of free nonrelativistic fermions in two dimensions and show that it is ultraviolet finite for finite fermi energies, but divergent in the infrared. In terms of the corresponding collective field theory this is a nonperturbative effect and is related to the soft behaviour of the usual thermodynamic entropy at high temperatures. We then show that thermodynamic en...
متن کاملOn the pulsating strings in AdS 4 × CP 3
We study the class of pulsating strings on AdS4 × CP . Using a generalized ansatz for pulsating string configurations we find new solutions of this class. Further we quasi-classically quantize the theory and obtain the first corrections to the energy. The latter, due to AdS/CFT correspondence, is supposed to give the anomalous dimensions of operators of the gauge theory dual N = 6 Chern-Simons ...
متن کاملN ov 2 00 4 Pulsating strings in warped AdS 6 × S 4 geometry
In this paper we consider pulsating strings in warped AdS 6 × S 4 background, which is a vacuum solution of massive type IIA super-string. The case of rotating strings in this background was considered in hep-th/0402202 and it was found that the results significantly differs from those considered in AdS 5 ×S 5. Motivated by this results we study pulsating strings in the warped spherical part of...
متن کاملNonrelativistic effective Lagrangians.
Chiral perturbation theory is extended to nonrelativistic systems with spontaneously broken symmetry. In the effective Lagrangian, order parameters associated with the generators of the group manifest themselves as effective coupling constants of a topological term, which is gauge invariant only up to a total derivative. In the case of the ferromagnet, a term connected with the Brouwer degree d...
