Repositorio: Docta Complutense
Aguirre Gamarra, Carlos Antonio

The concept of Socioemotional wealth has emerged as a promising theoretical framework which will help us to explain the particular aspects of family firms and to differentiate family firms from non-family firms (Dehlen, 2013). Similarly, the Socioemotional wealth approach is called to become the potential dominant paradigm in the family business field and the most important differentiator of the family firm as a unique entity (Berrone et al., 2012; Debicki et al., 2016; Hauck et al., 2016)....

Jannes, Gil|||0000-0002-1072-3267

We study selected aspects of quantum gravity phenomenology inspired by the gravitational analogy in Bose–Einstein condensates (BECs). We first review the basic ideas and formalism of analogue gravity in BECs, with particular emphasis on the possibility of simulating black holes. We stress that the dispersion relation in a BEC has a relativistic form in the hydrodynamic limit, and acquires non-relativistic, ‘superluminal’ modifications at high frequencies. This makes it a particularly...
