The effect of a confining boundary on the spatial variations in granular temperature of a driven quasi-2d layer of particles is investigated experimentally. The radial drop in the relative granular temperature ?T/T, exhibits a maximum at intermediate... Read More about Boundary effects in a quasi-two-dimensional driven granular fluid.

At the beginning of the previous century, Newtonian mechanics was advanced by two new revolutionary theories, Quantum Mechanics (QM) and General Relativity (GR). Both theories have transformed our view of physical phenomena, with QM accurately predic... Read More about Gravity in the quantum lab.

Gravitational mechanisms to self-tune the cosmological constant: obstructions and ways forward (2017)
Journal Article
Niedermann, F., & Padilla, A. (2017). Gravitational mechanisms to self-tune the cosmological constant: obstructions and ways forward. Physical Review Letters, 119(25), Article 251306. https://doi.org/10.1103/PhysRevLett.119.251306

Gravitational models of self-tuning are those in which vacuum energy has no observable effect on spacetime curvature, even though it is a priori unsuppressed below the cut-off. We complement Weinberg's no go theorem by studying field theoretic comple... Read More about Gravitational mechanisms to self-tune the cosmological constant: obstructions and ways forward.

Phonon spectroscopy with chirped shear and compressive acoustic pulses (2017)

Picosecond duration compressive and shear phonon wave packets injected into (311) GaAs slabs transform after propagation through ?1??mm into chirped acoustic pulses with a frequency increasing in time due to phonon dispersion. By probing the temporal... Read More about Phonon spectroscopy with chirped shear and compressive acoustic pulses.

Neural circuitry underlying sustained attention in healthy adolescents and in ADHD symptomatology (2017)
Journal Article

Moment-to-moment reaction time variability on tasks of attention, often quantified by intra-individual response variability (IRV), provides a good indication of the degree to which an individual is vulnerable to lapses in sustained attention. Increa... Read More about Neural circuitry underlying sustained attention in healthy adolescents and in ADHD symptomatology.

Coupling a mesoscopic conductor to a microwave cavity can lead to fascinating feedback effects which generate strong correlations between the dynamics of photons and charges. We explore the connection between cavity dynamics and charge transport in... Read More about Noise switching at a dynamical critical point in a cavity-conductor hybrid.
