A Cluster Algorithm for the Z 2 Kalb - Ramond Model
نویسنده
چکیده
A cluster algorithm is presented for the Z 2 Kalb-Ramond plaquette model in four dimensions which dramatically reduces critical slowing. The critical exponent z is reduced from z > 2 (standard Metropolis algorithm) to z = 0.32 ± 0.06. The Cluster algorithm updates the monopole configuration known to be responsible for the second order phase transition.

Topological mass term in effective Brane-World scenario with torsion
In this work we investigate a braneworld scenario where a Kalb-Ramond field propagates, together with gravity, in a five dimensional AdS slice. The rank-2 Kalb-Ramond field is associated with torsion. We study the compactification of the Kalb-Ramond field to four dimensional space-time without gauge fixing, focusing on the effects of torsion. On the brane the Kalb-Ramond field interacts with Aμ...
متن کاملDuality and an Operator Realization for the Fermi-Bose Transmutation in 3+1 Dimensions
We consider the Maxwell-Higgs system in the broken phase, described in terms of a Kalb-Ramond field interacting with the electromagnetic field through a topological coupling. We then study the creation operators of states which respectively carry a point charge and a closed magnetic string in the electromagnetic language or a point topological charge and a closed Kalb-Ramond charged string in t...
متن کاملExistence of Wormholes in Einstein-kalb-ramond Space Time
In recent, Kar.S et.al [ Phys Rev D 67,044005 (2003) ] have obtained static spherically symmetric solutions of the Einstein-Kalb-Ramond field equations. We have shown that their solutions, indeed, represent Wormholes. In Einstein-Cartan theory, the symmetric Christoffel connection is modified with the introduction of an anti-symmetric tensorial term,known as space time torsion, which is presume...
متن کاملRandall-Sundrum with Kalb-Ramond field: return of the hierarchy problem?
We show that when the antisymmetric Kalb-Ramond field is included in the Randall-Sundrum scenario, although the hierarchy problem can be solved, it requires an extreme fine tuning of the Kalb-Ramond field (about 1 part in 10). We interpret this as the return of the problem in disguise. Further, we show that the Kalb-Ramond field induces a small negative cosmological constant on the visible brane.
متن کاملBouncing cosmology from Kalb-Ramond Braneworld
We consider a 3-brane embedded in a warped 5-dimensional background with a dilaton and a Kalb-Ramond 2-form. We show that it is possible to find static solutions of the form of charged dS/AdS-like black hole with horizon which could have a negative mass parameter. The motion of the 3-brane in this bulk generates an effective 4dimensional bouncing cosmology induced by the negative dark radiation...
