Manipulating Ferroelectric Topological Polar Structures with Twisted Light

Advanced Materials, EarlyView.
We demonstrate dynamic control of ferroelectric order in quasi‐2D CsBiNb2O7 using twisted ultraviolet light carrying orbital angular momentum. Our approach harnesses non‐resonant multiphoton absorption and induced strain to modulate topological of ferroelectric polarization textures.

Heterogeneous Nanopore Arrays – Selective Modification of Nanopores Embedded in a Membrane

Advanced Materials, EarlyView.
Biological processes rely on the concerted action of channels with different functionalities embedded in the same membrane. Inspired by nature, heterogeneous nanopore arrays are prepared where two nanopores are connected in parallel and function as two different elements of an ionic circuit: a diode and a resistor.

Unveiling a magnetized jet from a low-mass protostar

Nature Communications, 2018
The presence of magnetic fields in protostellar jets has been predicted theoretically, but its experimental confirmation has been elusive so far. Here, the authors report the detection of SiO line polarisation in the HH 211 protostellar jet, indicative ...

Einstein and Rastall theories of gravitation in comparison

European Physical Journal C: Particles and Fields, 2018
We profit by a recent paper of Visser claiming that Rastall gravity is equivalent to Einstein gravity to compare the two gravitational theories in a general way. Our conclusions are different from Visser’s ones.

Glaphene: A Hybridization of 2D Silica Glass and Graphene

Advanced Materials, EarlyView.
‘Glaphene’, a novel hybrid material combining 2D silica glass and graphene, is synthesized via a scalable liquid precursor‐based vapor‐phase growth. This study reveals interlayer hybridization beyond van der Waals interactions, leading to emergent semiconducting behavior.

Low‐Energy, Ultrafast Spin Reorientation at Competing Hybrid Interfaces with Tunable Operating Temperature

Advanced Materials, EarlyView.
A spin reorientation transition is generated at hybrid interfaces of Pt‐Co‐organic molecules in the vicinity of room temperature. This spin reorientation transition happens at an ultrafast scale and is controlled either through electrical current or fs laser pulse, introducing perpendicular magnetic anisotropy in formerly planar magnetised samples ...

Identification of subsurface cavities in urban environment

Scientific Reports
Gravimetry is the most suitable geophysical method for identifying subsurface cavities in urban or industrial environments, as it is unaffected by nearby electromagnetic disturbances.

Making the Most of Kepler Photometry: Characterizing Exoplanets through Phase Curve Analysis

EPJ Web of Conferences, 2015
The Kepler mission’s long-term monitoring of stars through high-precision photometry has not only revealed a plethora of exoplanet transits but also provided valuable data for characterizing a subset of these planets.
