Method for the nmr based determination of the affinity of drugs for a target protein

Geoffrey Bodenhausen, Aurélien Bornet, Nicola Salvi, Roberto Buratto

The document relates to a method for the determination of the binding properties of at least one first chemical compound to at least one second chemical compound between a free essentially dissociated state and a bound essentially associated state by using ...

Persistent Bidirectional Optical Switching in the 2D High-Spin Polymer {[Fe(bbtr)3](BF4)2}∞

Philip Pattison, Pradip Chakraborty

In the covalently linked 2D coordination network {Fe(bbtr)32}∞, bbtr = 1,4-di(1,2,3-triazol-1-yl)butane, the iron(II) centers stay in the high-spin (HS) state down to 10 K. They can, however, be quantitatively converted to the low-spin (LS) state by ...

Experimental investigation of the low-temperature features of a random Heisenberg spin chain

Joël Mesot, Krunoslav Prsa

Low-dimensional spin systems, consisting of arrays of spins arranged in chains or ladders, have been investigated intensively in recent years using both exactly solvable theoretical models as well as a variety of experimental techniques. In case of random ...

Dissociation dynamics of singly charged vortices into half-quantum vortex pairs

Benoît Marie Joseph Deveaud, Vincenzo Savona, Timothy Chi Hin Liew, Konstantinos Lagoudakis, Francesco Manni

The quest for identification and understanding of fractional vorticity is a major subject of research in the quantum fluids domain, ranging from superconductors, superfluid Helium-3 to cold atoms. In a two-dimensional Bose degenerate gas with a spin degree ...

Observation of New Resonant Structures in gamma gamma -> omega phi, phi phi, and omega omega

Olivier Schneider, Yiming Li, Chao Wang, Tagir Aushev, Jun Yong Kim, Remi Léandre Albert Louvot, Ji Hyun Kim, Xiao Wang, Jing Li, Xuan Li

The processes gamma gamma -> omega phi,phi phi, and omega omega are measured using an 870 fb(-1) data sample collected with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. Production of vector meson pairs is clearly observed and their c ...

Theory of inelastic light scattering in spin-1 systems: Resonant regimes and detection of quadrupolar order

Frédéric Mila, Frédéric Alexis Michaud, François Vernay

Motivated by the lack of an obvious spectroscopic probe to investigate nonconventional order such as quadrupolar orders in spin S > 1/2 systems, we present a theoretical approach to inelastic light scattering for spin-1 quantum magnets in the context of a ...

Polaritonic devices

Timothy Chi Hin Liew

We review the current hopes for applications of exciton-polaritons in semiconductor microcavities. These quasi-particles have become distinguished in recent years for a variety of different effects including Bose-Einstein condensation, ballistic spin curre ...

Magnetization and specific heat of the dimer system CuTe2O5

Helmuth Berger, Zheng Wang

We report on magnetization and specific heat measurements on single-crystalline CuTe2O5. The experimental data are directly compared to theoretical results for two different spin structures, namely an alternating spin-chain and a two-dimensional (2D) coupl ...

Formation of magnetic domains and domain walls in epitaxial Fe3O4(100) elements (invited)

Magnetic domains and domain walls in epitaxial Fe3O4(100) elements (rings and wires) are imaged using magnetic force microscopy and photoemission electron microscopy. We show that the interplay between the four-fold magnetocrystalline anisotropy and the sh ...

Deep inelastic scattering in conformal QCD

We consider the Regge limit of a CFT correlation function of two vector and two scalar operators, as appropriate to study small-x deep inelastic scattering in N = 4 SYM or in QCD assuming approximate conformal symmetry. After clarifying the nature of the R ...
