A Uranium-Based UO2+-Mn2+ Single-Chain Magnet Assembled trough Cation-Cation Interactions

Marinella Mazzanti, Lucile Sylvie Danielle Chatelain

Single-chain magnets (SCMs) are materials composed of magnetically isolated one-dimensional (1D) units exhibiting slow relaxation of magnetization. The occurrence of SCM behavior requires the fulfillment of stringent conditions for exchange and anisotropy ...

Orbital occupancies and the putative j(eff)=1/2 ground state in Ba2IrO4: A combined oxygen K-edge XAS and RIXS study

Henrik Moodysson Rønnow

The nature of the electronic ground state of Ba2IrO4 has been addressed using soft x-ray absorption and inelastic scattering techniques in the vicinity of the oxygen K edge. From the polarization and angular dependence of x-ray absorption spectroscopy (XAS ...

Atomic and electronic structure of a Rashba p-n junction at the BiTeI surface

Marco Grioni, Oleg Yazyev, Helmuth Berger, Philippe Bugnon, Gabriel Albert Autes, Cédric Tournier-Colletta

The non-centro-symmetric semiconductor BiTeI exhibits two distinct surface terminations that support spin-split Rashba surface states. Their ambipolarity can be exploited for creating spin-polarized p-n junctions at the boundaries between domains with diff ...

Solving the infinite-horizon constrained LQR problem using splitting techniques

Colin Neil Jones, Milan Korda, Georgios Stathopoulos

This paper presents a method to solve the constrained infinite-time linear quadratic regulator (LQR) problem. We use an operator splitting technique, namely the alternating minimization algorithm (AMA), to split the problem into an unconstrained LQR proble ...

Spin Texture of Bi2Se3 Thin Films in the Quantum Tunneling Limit

Jan Hugo Dil, Stefan Peter Muff

By means of spin- and angle-resolved photoelectron spectroscopy we studied the spin structure of thin films of the topological insulator Bi2Se3 grown on InP(111). For thicknesses below six quintuple layers the spin- polarized metallic topological surface s ...

Electrical Transport Properties of Single-Layer WS2

Andras Kis, Dumitru Dumcenco, Dmitry Ovchinnikov, Adrien Victor Allain

We report on the fabrication of field-effect transistors based on single layers and bilayers of the semiconductor WS2 and the investigation of their electronic transport properties. We find that the doping level strongly depends on the device environment a ...

Hunting composite vector resonances at the LHC: naturalness facing data

Davide Greco, Da Liu

We introduce a simplified low-energy effective Lagrangian description of the phenomenology of heavy vector resonances in the minimal composite Higgs model, based on the coset SO(5)/SO(4), analysing in detail their interaction with lighter top partners. Our ...

The resonant substructure of B-s(0) -> (D) over bar K-0(-)pi(+) decays is studied using a data sample corresponding to an integrated luminosity of 3.0 fb(-1) of pp collision data recorded by the LHCb detector. An excess at m((D) over bar K-0(-)) approximat ...

Direct observation of the spin texture in SmB6 as evidence of the topological Kondo insulator

Jan Hugo Dil, Joël Mesot, Stefan Peter Muff, Kazimierz Conder

Topological Kondo insulators have been proposed as a new class of topological insulators in which non-trivial surface states reside in the bulk Kondo band gap at low temperature due to strong spin-orbit coupling. In contrast to other three-dimensional topo ...
