We show that a double quantum-dot system made of diluted magnetic semiconductor behaves unlike usual molecules. In a semiconductor double quantum dot or in a diatomic molecule, the ground state of a single carrier is described by a symmetric orbital. In a magnetic material molecule, new ground states with broken symmetry can appear due the competition between the tunnelling and magnetic polaron...

The interpretation of optical spectra requires thorough comprehension quantum mechanics, especially understanding the concept angular momentum operators. Suppose now that a transformation from laboratory-fixed to molecule-attached coordinates, by invoking correspondence principle, induces reversed operator identities. However, foundations mechanics and mathematical implementation specific symme...

We theoretically study the ionization enhancement of diatomic molecular ion ${\mathrm{H}}_{2}{}^{+}$ at two critical internuclear distances $R$, using orthogonal two-color laser fields. The polarization fundamental infrared field and a weak second-harmonic is parallel perpendicular to axis, respectively. It observed that adding raises slightly first peak smaller whereas it enhances second one l...

the main diatomic structure-forming species of the zayandehrud reservoir was investigated by collecting samples from the surface, five, seven and 10 m depths from january 2011 to october 2012 along four linear transects. asterionella formosa hassall, cyclotella ocellata pantocsek and fragilaria crotonensis kitton were revealed as the three structure-forming species among diatomic algae in the r...

The doublet and quartet potential energy surfaces for the P + SO → PO S reaction are explored using highly accurate explicit correlation multireference configuration interaction method, is found to be thermodynamically favorable, with an exothermicity value of 70.5 kJ mol−1. electronic structure, spectra, bond dissociation energies intermediates involved in reaction, such as SPO, PSO, SOP, calc...

We explore the quantum dynamics of heteronuclear atomic collisions in waveguides and demonstrate the existence of a novel mechanism for the resonant formation of polar molecules. The molecular formation probabilities can be tuned by changing the trap frequencies characterizing the transverse modes of the atomic species. The origin of this effect is the confinement-induced mixing of the relative...
