Inorg Chem. 2014 Oct 06;53(19):10708-15. doi: 10.1021/ic501854g. Epub 2014 Sep 22.

This work reports an X-ray diffraction, X-ray absorption, and Raman spectroscopy study of [(CH₃)₄N]₂MnX₄ (X = Cl, Br) under pressure. We show that both compounds share a similar phase diagram with pressure. A P2₁/c monoclinic structure describes precisely the...

ac Josephson effect in finite-length nanowire junctions with Majorana modes.

Physical review letters

PMID: 23004641
Phys Rev Lett. 2012 Jun 22;108(25):257001. doi: 10.1103/PhysRevLett.108.257001. Epub 2012 Jun 18.

It has been predicted that superconducting junctions made with topological nanowires hosting Majorana bound states (MBS) exhibit an anomalous 4π-periodic Josephson effect. Finding an experimental setup with these unconventional properties poses, however, a serious challenge: for finite-length wires, the...

CONTEXT: Barnard B1b has revealed as one of the most interesting globules from the chemical and dynamical point of view. It presents a rich molecular chemistry characterized by large abundances of deuterated and complex molecules. Furthermore, it hosts an...

A Pt/Al2O3-supported metal-organic framework film as the size-selective core-shell hydrogenation catalyst.

Chemical communications (Cambridge, England)

Aguado S, El-Jamal S, Meunier F, Canivet J, Farrusseng D.

Chem Commun (Camb). 2016 Jun 04;52(44):7161-3. doi: 10.1039/c6cc03096c. Epub 2016 May 12.

The substituted imidazolate-based MOF (SIM-1) easily forms a homogeneous layer at the surface of millimetric platinum-loaded alumina beads. This new core-shell SIM-1@Pt/Al2O3 catalyst shows the fine molecular sieving effect for the Pt-catalyzed hydrogenation of carbon-carbon double bonds.

The Photodissociation of HCN and HNC: Effects on the HNC/HCN Abundance Ratio in the Interstellar Medium.

The Astrophysical journal

Astrophys J. 2017 Mar 20;838(1). doi: 10.3847/1538-4357/aa63ee. Epub 2017 Mar 21.

The impact of the photodissociation of HCN and HNC isomers is analyzed in different astrophysical environments. For this purpose, the individual photodissociation cross section of HCN and HNC isomers have been calculated in the 7-13.6 eV photon energy range...

Magnetically-driven colossal supercurrent enhancement in InAs nanowire Josephson junctions.

PMID: 28401951
Nat Commun. 2017 Apr 12;8:14984. doi: 10.1038/ncomms14984.

The Josephson effect is a fundamental quantum phenomenon where a dissipationless supercurrent is introduced in a weak link between two superconducting electrodes by Andreev reflections. The physical details and topology of the junction drastically modify the properties of the...

Majorana bound states from exceptional points in non-topological superconductors.

Recent experimental efforts towards the detection of Majorana bound states have focused on creating the conditions for topological superconductivity. Here we demonstrate an alternative route, which achieves fully localised zero-energy Majorana bound states when a topologically trivial superconductor is...

Phys Rev Lett. 2000 Feb 28;84(9):1986-9. doi: 10.1103/PhysRevLett.84.1986.

We propose a measurement setup for detecting quantum noise over a wide frequency range using inelastic transitions in a tunable two-level system as a detector. The frequency-resolving detector consists of a double quantum dot which is capacitively coupled to...

Coupled diabatic potential energy surfaces for studying the nonadiabatic dynamics at conical intersections in angular resolved photodetachment simulations of OHF--->OHF+e-.

PMID: 17092087
J Chem Phys. 2006 Oct 28;125(16):164321. doi: 10.1063/1.2363988.

An energy-based method is proposed for the diabatization of the OH(2Pi)+F(2P)-->O(3P)+HF(1Sigma+) reaction. It is demonstrated that the diabatic representation obtained is regularized, i.e., the residual derivative couplings do not present singularities at the conical intersections appearing along the reaction...
