The phase diagram of the massive Gross-Neveu model, revisited

open access: yes, 2005
The massive Gross-Neveu model is solved in the large N limit at finite temperature and chemical potential. The phase diagram features a kink-antikink crystal phase which was missed in previous works.

Antiprotonic helium atomcules

open access: yesEPJ Web of Conferences, 2012
About 3% of antiprotons () stopped in helium are long-lived with microsecond lifetimes, against picoseconds in all other materials. This unusual longevity has been ascribed to the trapping of on metastable bound states in He+ helium atom-molecules thus ...

Cis‐unsaturated sphingolipids support growth of sphingoid base‐deficient yeast but impair plasma membrane integrity

open access: yesFEBS Open Bio, EarlyView.
Sphingoid base structures, the sphingolipid backbones, vary among species. We established yeast cells in which the native sphingoid base was replaced with plant‐type bases containing cis or trans double bonds. This is, to our knowledge, the first eukaryotic model mostly composed of sphingolipids containing cis‐unsaturated sphingoid base, providing a ...

Ultracold atoms in optical lattices with random on-site interactions

open access: yes, 2005
We consider the physics of lattice bosons affected by disordered on-site interparticle interactions. Characteristic qualitative changes in the zero temperature phase diagram are observed when compared to the case of randomness in the chemical potential ...

Statins induce monocytic differentiation in acute myeloid leukemia cells through the KLF4/DPYSL2A axis

open access: yesFEBS Open Bio, EarlyView.
Statins, identified via the Comparative Toxicogenomics Database, promote monocytic differentiation and apoptosis in non‐APL AML cells by upregulating DPYSL2A through a KLF4‐dependent pathway. Mevalonate supplementation reversed these effects, indicating involvement of the mevalonate pathway.

Ab initio determination of exchange integrals and Neel temperature in the chain cuprates

open access: yes, 1998
We report ab initio quantum chemical cluster calculations of the chain (J_a) and the largest interchain (J_b) Heisenberg exchange of the chain cuprates Ca_2CuO_3 and Sr_2CuO_3.
