Degree of the divisor of solutions of a differential equation on a projective variety [PDF]
Using the data schemes developed by Arrondo-Sols-Speiser, we give a rigorous definition of algebraic differential equations on the complex projective space $P^n$.

Pipeline model of a Fermi-sea electron pump [PDF]
The use of a band offset between the two leads of an electron pump driven by a local oscillating voltage is shown to increase the pump current dramatically.

Coherent ratchets in driven Bose-Einstein condensates [PDF]
We study the response of a Bose-Einstein condensate to an unbiased periodic driving potential. By controlling the space and time symmetries of the driving we show how a directed current can be induced, producing a coherent quantum ratchet.

Racionalidad de la inducción como minimización entrópica
Rationality of induction as entropic minimizationIn favour of a fundamental aspect of the epistemology of Mariano Artigas –his commitment to the quest for truth on the part of the scientific theory– I argue about the rationality of the process of ...

Generation of uniform synthetic magnetic fields by split driving of an optical lattice [PDF]
We describe a method to generate a synthetic gauge potential for ultracold atoms held in an optical lattice. Our approach uses a time-periodic driving potential based on two quickly alternating signals to engineer the appropriate Aharonov-Bohm phases ...

Controlled generation of coherent matter-currents using a periodic driving field [PDF]
We study the effect of a strong, oscillating driving field on the dynamics of ultracold bosons held in an optical lattice. Modeling the system as a Bose-Hubbard model, we show how the driving field can be used to produce and maintain a coherent atomic ...

Artificialisation des sols et érosion hydrique dans la ville de Daloa, centre-ouest de la Côte d’Ivoire [PDF]
Résumé : L’artificialisation des sols induite par l’étalement de la tache urbaine de Daloa pose le problème de l’exposition des sols au risque d’érosion hydrique.

Perturbative analysis of coherent quantum ratchets in cold atom systems [PDF]
We present a perturbative study of the response of cold atoms in an optical lattice to a weak time- and space-asymmetric periodic driving signal. In the noninteracting limit, and for a finite set of resonant frequencies, we show how a coherent, long ...

Certeza razonable en ciencia y filosofía
Reasonable certainty in science and philosophyIt is argued that, as forms of knowledge, neither science is so safe nor philosophy is as arbitrary as often claimed.
