Theory of Dynamic Stripe Induced Superconductivity
Annette Bussmann-Holder, K. Alex Muller, Roman Micnas +4
Since the recently reported giant isotope effect on T* [1] could be consistently explained within an anharmonic spin-charge-phonon interaction model, we consider here the role play…
On Construction of Recursion Operator and Algebra of Symmetries for Field and Lattice Systems
Maciej Blaszak
In the paper, developing the idea of V. Sokolov et all. (J.Math.Phys. 40 (1999)6473 we construct recursion operators and hereditary algebra of symmetries for many field and lattice…
Spin effects in ferromagnetic single-electron transistors
J. Barnas, J. Martinek, G. Michalek +2
Electron tunneling in ferromagnetic single-electron transistors is considered theoretically in the sequential tunneling regime. A new formalism is developed, which operates in a tw…
Trions in a periodic potential
Wojciech Florek
The group-theoretical classification of trion states is presented. It is based on considerations of products of irreducible representations of the 2D translation group. For a given…
Novel criticality in a model with absorbing states
Adam Lipowski
We study a one-dimensional model which undergoes a transition between an active and an absorbing phase. Monte Carlo simulations supported by some additional arguments prompted as t…
Experimental realization of a 2D fractional quantum spin liquid
R. Coldea, D. A. Tennant, A. M. Tsvelik +1
The ground-state ordering and dynamics of the two-dimensional (2D) S=1/2 frustrated Heisenberg antiferromagnet Cs_2CuCl_4 is explored using neutron scattering in high magnetic fiel…
