Stress induces remodelling of yeast interaction and co-expression networks
Sonja Lehtinen, Francesc Xavier Marsellach, Sandra Codlin +6
Network analysis provides a powerful framework for the interpretation of genome-wide data. While static network approaches have proved fruitful, there is increasing interest in the…
Some remarks on the entropy for algebraic actions of amenable groups
Nhan-Phu Chung, Andreas Thom
In this short note we study the entropy for algebraic actions of certain amenable groups. The possible values for this entropy are studied. Various fundamental results about certai…
Intrinsic pinning and the critical current scaling of clean epitaxial Fe(Se,Te) thin films
Kazumasa Iida, Jens Haenisch, Elke Reich +11
We report on the transport properties of clean, epitaxial Fe(Se,Te) thin films prepared on Fe-buffered MgO (001) single crystalline substrates by pulsed laser deposition. Near Tc a…
Stacked topological insulator built from bismuth-based graphene sheet analogues
Bertold Rasche, Anna Isaeva, Michael Ruck +7
Commonly materials are classified as either electrical conductors or insulators. The theoretical discovery of topological insulators (TIs) in 2005 has fundamentally challenged this…
Pressure dependence of the charge density wave in 1T-TaS2 and its relation to superconductivity
T. Ritschel, J. Trinckauf, G. Garbarino +5
We present a state-of-the-art x-ray diffraction study of the charge density wave order in 1T-TaS2 as a function of temperature and pressure. Our results prove that the charge densi…
Magnetic state of pyrochlore Cd2Os2O7 emerging from strong competition of ligand distortions and longer-range crystalline anisotropy
Nikolay A. Bogdanov, Rémi Maurice, Ioannis Rousochatzakis +2
By many-body quantum-chemical calculations, we investigate the role of two structural effects - local ligand distortions and the anisotropic Cd-ion coordination - on the magnetic s…
