Freezing of Nonlinear Bloch Oscillations in the Generalized Discrete Nonlinear Schrodinger Equation
The dynamics in a nonlinear Schrodinger chain in an homogeneous electric
field is studied. We show that discrete translational invariant
integrability-breaking terms can freeze the Bloch nonlinear oscillations and
introduce new faster frequencies in their dynamics. These phenomena are studied
by direct numerical integration and through an adiabatic approximation. The
adiabatic approximation allows a description in terms of an effective potential
that greatly clarifies the phenomenon.Comment: LaTeX, 7 pages, 6 figures. Improved version to appear in Phys. Rev.

Quantum estimation of the Schwarzschild space-time parameters of the Earth
We propose a quantum experiment to measure with high precision the
Schwarzschild space-time parameters of the Earth. The scheme can also be
applied to measure distances by taking into account the curvature of the
Earth's space-time. As a wave-packet of (entangled) light is sent from the
Earth to a satellite it is red-shifted and deformed due to the curvature of
space-time. Measurements after the propagation enable the estimation of the
space-time parameters. We compare our results with the state of the art, which
involves classical measurement methods, and discuss what developments are
required in space-based quantum experiments to improve on the current
measurement of the Schwarzschild radius of the Earth.Comment: 11 pages, no figures. Ivette Fuentes previously published as Ivette

Design and experimental assessment of a novel damper with high endurance to seismic loads
The study presents the design and the experimental characterization of a new energy dissipation device aimed at providing improved resistance to repeated seismic loads. Differently from conventional steel hysteretic dampers, which dissipate energy by yielding of a mild steel core and are noted to suffer low-cycle fatigue, the new damper provides energy dissipation by the friction that is activated between a moving shaft and a lead core prestressed within a tube. The prestress level is controlled during the assembling process, allowing to adjust the axial strength of the damper. Thanks to the ability of lead to restore its properties by static recrystallization taking place immediately after deformation, repeated cycles of loading do not produce damages that may accrue and eventually lead to failure of the device. Moreover, prestressing of the lead core allows to achieve high specific strength (i.e., high force to volume ratio), thereby providing low dimensions which help to reduce the architectural invasiveness. Prototypes of the damper were subjected to the test procedure established in the European standard EN 15129 for Displacement Dependent Devices, fulfilling the relevant requirements. The damper provides a robust and stable response over repeated cycles, characterized by essentially rectangular hysteresis loops with an equivalent viscous damping ratio ξeff of about 55%. Moreover, it shows low sensitivity of mechanical properties on the loading rate and the ability to withstand multiple cycles of motion at the design earthquake displacement without deterioration of performance, demonstrating maintenance-free operation in presence of repeated ground shakes. Its ability to survive several strong motions without being damaged, and its high damping capability coupled to a
compact design and low manufacturing cost, are the distinctive features that make it suitable for social housing
