Kants Konzeption kosmologischer Freiheit – ein metaphysischer Rest?
2017
Die deutschen Idealisten waren der Auffassung, Kant habe mit seiner transzendentalen Umwälzung der Begründungsproblematik eine Revolution in der philosophischen Denkungsart in Gang gesetzt, die es weniger aufzuhalten als vielmehr dadurch zu vollbringen gelte, daß die Voraussetzungen oder ‚Fundamente‘ der Kantischen Philosophie selbst kritisch in den Blick genommen würden. Zu diesen Voraussetzungen gehört zweifelsohne Kants Architektonik der Vernunft im allgemeinen und die Stellung, die dem Freiheitsbegriff dabei zukommt, im besonderen. Es wird gezeigt, daß Kants Bestimmung kosmologischer oder transzendentaler Freiheit nicht so sehr einen sicheren Ausgangspunkt für Erkundungen im Rahmen der …
Towards a new conception of metaphysics: Lambert’s criticism on Wolff’s mathematical method
2017
This paper discusses Lambert’s criticism of Wolff’s mathematical method. I take this criticism to consist of two main aspects. Lambert tries on the one hand to revise Wolff’s idea of fundamental concepts by providing what he takes to be a more profound theory of concepts. On the other hand, Lambert introduces postulates that regulate the connection between fundamental concepts and account for their application to experience. Both transformations allow Lambert to put forward a novel approach to metaphysics which is essentially oriented towards experience.
Libertad, responsabilidad y razones morales
1997
Not available<br><br>Sila elección está causada por factores ajenos a la voluntad del agente, la libertad y la responsabilidad moral parecen perder su base. Pero si la elección carece de causas, se convierte en un acto irracional y, con ello, irresponsable. La salida de este dilema consiste en advertir la importancia de las razones morales en la deliberación práctica. De acuerdo con la tesis central del presente trabajo, la sensibilidad hacia las razones morales es una condición necesaria de la libertad y la responsabilidad moral. La inconmensurabilidad de tales razones con las razones no morales concede a la elección el lugar central que demanda la responsabilidad moral, pero, …

Generation of Frames
2004
It is well known that, given a generic frame, there exists a unique frame operator which satisfies, together with its adjoint, a double operator inequality. In this paper we start considering the inverse problem, that is how to associate a frame to certain operators satisfying the same kind of inequality. The main motivation of our analysis is the possibility of using frame theory in the discussion of some aspects of the quantum time evolution, both for open and for closed physical systems.
$$\mathscr {D}{-}$$ D - Deformed and SUSY-Deformed Graphene: First Results
2016
We discuss some mathematical aspects of two particular deformed versions of the Dirac Hamiltonian for graphene close to the Dirac points, one involving \(\mathscr {D}\)-pseudo bosons and the other supersymmetric quantum mechanics. In particular, in connection with \(\mathscr {D}\)-pseudo bosons, we show how biorthogonal sets arise, and we discuss when these sets are bases for the Hilbert space where the model is defined, and when they are not. For the SUSY extension of the model we show how this can be achieved and which results can be obtained.
Implications of the Semigeostrophic Nature of Rossby Waves for Rossby Wave Packet Detection
2015
Abstract Upper-tropospheric Rossby wave packets have received increased attention recently. In most previous studies wave packets have been detected by computing the envelope of the meridional wind field using either complex demodulation or a Hilbert transform. The latter requires fewer choices to be made and appears, therefore, preferable. However, the Hilbert transform is fraught with a significant problem, namely, a tendency that fragments a single wave packet into several parts. The problem arises because Rossby wave packets show substantial deviations from the almost-plane wave paradigm, a feature that is well represented by semigeostrophic dynamics. As a consequence, higher harmonics …
Phonon-to-spin mapping in a system of a trapped ion via optimal control
2015
We propose a protocol for measurement of the phonon number distribution of a harmonic oscillator based on selective mapping to a discrete spin-1/2 degree of freedom. We consider a system of a harmonically trapped ion, where a transition between two long-lived states can be driven with resolved motional sidebands. The required unitary transforms are generated by amplitude-modulated polychromatic radiation fields, where the time-domain ramps are obtained from numerical optimization by application of the chopped random basis algorithm (CRAB). We provide a detailed analysis of the scaling behavior of the attainable fidelities and required times for the mapping transform with respect to the size…
