Weak measurement og the composite Goo-Haenchen shift in the critical region / Santana, Octavio J S ; Carvalho, Silvania A ; De Leo, Stefano ; de Araujo, Luis E E
By using a weak measurement technique, we investigated the interplay between the angular and lateral Goos-Haenchen shift of a focused He-Ne laser beam for incidence near the critical angle. We verified that this interplay dramatically affects the composite Goos-Haenchen shift of the propagated beam. [...]

Evidence of light guiding in ion-implanted diamond / Lagomarsino, S ; Olivero, P ; Bosia, F ; Vannoni, M ; Calusi, S ; Giuntini, L ; Massi, M
We demonstrate the feasibility of fabricating light-waveguiding microstructures in bulk single-crystal diamond by means of direct ion implantation with a scanning microbeam, resulting in the modulation of the refractive index of the ion-beam damaged crystal. Direct evidence of waveguiding through such buried microchannels is obtained with a phase-shift micro-interferometric method allowing the study of the multi-modal structure of the propagating electromagnetic field.

SUSY Method for the Three-Dimensional Schr\"odinger Equation with Effective Mass / Ioffe, M V ; Kolevatova, E V ; Nishnianidze, D N
The three-dimensional Schr\"odinger equation with a position-dependent (effective) mass is studied in the framework of Supersymmetrical (SUSY) Quantum Mechanics. The general solution of SUSY intertwining relations with first order supercharges is obtained without any preliminary constraints. [...]

Solution of Second Order Supersymmetrical Intertwining Relations in Minkowski Plane / Ioffe, M V ; Kolevatova, E V ; Nishnianidze, D N
Supersymmetrical (SUSY) intertwining relations are generalized to the case of quantum Hamiltonians in Minkowski space. For intertwining operators (supercharges) of second order in derivatives the intertwined Hamiltonians correspond to completely integrable systems with the symmetry operators of fourth order in momenta.

Directed flow in heavy-ion collisions at NICA: what is interesting to measure? / Bravina, L V ; Zabrodin, E E
We study the formation of the directed flow of hadrons in nuclear collisions at energies between AGS and SPS in Monte Carlo cascade model. The slope of the proton flow at midrapidity tends to zero (softening) with increasing impact parameter of the collision. [...]

Studying the $\rho$ resonance parameters with staggered fermions / Fu, Ziwen ; Wang, Lingyun
We deliver a lattice study of $\rho$ resonance parameters with p-wave $\pi\pi$ scattering phases, which are extracted by finite-size methods at one center-of-mass frame and four moving frames for six MILC lattice ensembles with pion masses ranging from $346$ to $ 176$ MeV. The effective range formula is applied to describe the scattering phases as a function of the energy covering the resonance region, this allows us to extract $\rho$ resonance parameters and to investigate the quark-mass dependence.

Radiation Hardness of 30 cm Long CsI(Tl) Crystals / Longo, Savino ; Roney, John Michael
Measurements of the degradation in performance of 30 cm long CsI(Tl) scintillation crystals exposed to 1 MeV photon doses of 2, 10, 35, 100 and 1000 Gy are presented. The light yield, light yield longitudinal non-uniformity, scintillation decay times, energy resolution and timing resolution of a set of spare crystals from the BABAR and Belle experiments are studied as a function of these doses. [...]

A 3-dimensional interdigitated electrode geometry for the enhancement of charge collection efficiency in diamond detectors / Forneris, J ; Giudice, A Lo ; Olivero, P ; Picollo, F ; Re, A ; Marinelli, M ; Pompili, F ; Verona, C ; Rinati, G Verona ; Benetti, M et al.
In this work, a single crystal CVD diamond film with a novel three-dimensional (3D) interdigitated electrode geometry has been fabricated with the Reactive Ion Etching (RIE) technique in order to increase the charge collection efficiency (CCE) with respect to that obtained by standard superficial electrodes. The geometrical arrangement of the electric field lines due to the 3D patterning of the electrodes results in a shorter travel path for the excess charge carriers, thus contributing to a more efficient charge collection mech-anism.

Microelectrode arrays of diamond-insulated graphitic channels for real time detection of exocytotic events from cultured chromaffin cells and slices of adrenal glands / Picollo, F ; Battiato, A ; Bernardi, E ; Marcantoni, A ; Pasquarelli, A ; Carbone, E ; Olivero, P ; Carabelli, V
A microstructured graphitic 4x4 multielectrode array was embedded in a single crystal diamond substrate (4x4 {uG-SCD MEA) for real-time monitoring of exocytotic events from cultured chromaffin cells and adrenal slices. The current approach relies on the development of a parallel ion beam lithographic technique, which assures the time effective fabrication of extended arrays with reproducible electrode dimensions.
