متن کاملBlack Hole Entropy and Entropy of Entanglement
We compare the one-loop corrections to the entropy of a black hole, from quantum fields of spin zero, one-half, and one, to the entropy of entanglement of the fields. For fields of spin zero and one-half the black hole entropy is identical to the entropy of entanglement. For spin one the two entropies differ by a contact interaction with the horizon which appears in the black hole entropy but n...
متن کاملClinical Pathology Teaching in Laboratory by Socratic Method
Introduction: In recent decades, a variety of teaching methods has been offered for teaching different fields of science, but the old method of questions and answer is still popular and in use. This teaching method, generally applicable to small groups, is based on questioning and finding answers by students which can increase active learning. This study evaluated students' viewpoints toward cl...
متن کاملOn Lagrangian Formulation for Half-integer HS Fields within Hamiltonian BRST Approach
A recent progress in a gauge-invariant Lagrangian description of massive and massless half-integer higher-spin fields in AdS and Minkowski spaces is presented. The procedure is based on a BFV-BRST operator, encoding the initial conditions realized by constraints in a Fock space and extracting the higher-spin fields from unitary irreducible representations of the AdS (Poincare) group. The constr...
متن کاملQuantum transport in nonuniform magnetic fields: Aharonov-Bohm ring as a spin switch.
We study spin-dependent magnetoconductance in mesoscopic rings subject to an inhomogeneous in-plane magnetic field. We show that the polarization direction of transmitted spin-polarized electrons can be controlled via an additional magnetic flux such that spin flips are induced at half a flux quantum. This quantum interference effect is independent of the strength of the nonuniform field applie...
