Physics in the Global Monopole Spacetime
In this paper we review some important aspects of the global monopole spacetime and present how this manifold modifies, at classical and quantum points of view, the movement of a charged particle. The explicit calculations of the renormalized vacuum expectation values of the energy-momentum tensors, <FONT FACE=Symbol>á</FONT>T<FONT FACE=Symbol>mn</FONT>(x)<FONT FACE=Symbol>ñ</FONT>Ren., associated with massless bosonic and fermionic fields are also presented. Moreover the effect of the nonzero temperature in this previous formalism is analyzed. Finally, we briefly present other applications of this manifold in the topological inflation and condensed matter system.
