Time-resolved observation of a dynamical phase transition with atoms in a cavity Open
The transparence of a laser-driven optical resonator containing an ensemble\nof cold atoms can have two distinct, robust states. Atoms in their initially\nprepared pure state blockade the transmission by detuning the cavity mode from\nthe …

Collective self-trapping of atoms in a cavity Open
We study experimentally the optical dipole trapping of a cloud of cold atoms in a high-finesse cavity in the parameter regime where the atomic back-action on the cavity mode is significant. Back-action based effects lead to state selective…

Finite-size scaling of the photon-blockade breakdown dissipative quantum phase transition Open
We prove that the observable telegraph signal accompanying the bistability in the photon-blockade-breakdown regime of the driven and lossy Jaynes–Cummings model is the finite-size precursor of what in the thermodynamic limit is a genuine f…

New Insights on the Simultaneous Removal by Adsorption on Organoclays of Humic Acid and Phenol Open
The exploitation of thermal water as a heat source in houses and apartments (during winter) is a widely used alternative to natural gas. However, this type of water may contain organic contaminants, which must be removed before releasing t…

Comparison of various advanced oxidation processes for the degradation of phenylurea herbicides Open
Various types of advanced oxidation processes (AOPs), such as UV photolysis, ozonation, heterogeneous photocatalysis and their combinations were comparatively examined at the same energy input in a home-made reactor. The oxidative transfor…

Toxicology Aspects of the Decomposition of Diuron by advanced Oxidation Processes Open
Diuron is a phenylurea-based residual herbicide with toxic and endocrine disrupting effects. The aims of the present work were the comparison of the efficiency of various advanced oxidation processes, such as direct ultraviolet photolysis,…

“Crystallographic” holes: new insights for a beneficial structural feature for photocatalytic applications Open
The “crystallographic” holes obtained by simple hydrothermal crystallization/calcination can enhance the photocatalytic activity of TiO2 microcrystals with exposed {001} facets.

Visible light driven photocatalytic elimination of organic- and microbial pollution by rutile-phase titanium dioxides: new insights on the dynamic relationship between morpho-structural parameters and photocatalytic performance Open
For the visible light driven photocatalytic performance of rutile the presence of Ti–O–O– entities is more preferable than Ti3+.
