Charge transfer in DNA*

In the past few decades, charge transfer in DNA has attracted considerable attention from researchers in a wide variety of fields ranging from bioscience and physical chemistry to nanotechnology. Charge transfer in DNA has been investigated using various techniques. Among them, time-resolved spectroscopic methods have provided information on chargetransfer dynamics in DNA, an important basis fo...

Revisiting the semiclassical gravity scenario for gravitational collapse

The existence of extremely dark and compact astronomical bodies is by now a well established observational fact. On the other hand, classical General Relativity predicts the existence of black holes which fit very well with the observations, but do lead to important conceptual problems. In this contribution we ask ourselves the straightforward question: Are the dark and compact objects that we ...

An effective stochastic semiclassical theory for the gravitational field

Assuming that the mechanism proposed by Gell-Mann and Hartle works as a mechanism for decoherence and classicalization of the metric field, we formally derive the form of an effective theory for the gravitational field in a semiclassical regime. This effective theory takes the form of the usual semiclassical theory of gravity, based on the semiclassical Einstein equation, plus a stochastic corr...
