Open boundary conditions in stochastic transport processes with pair-factorized steady states
Hannes Nagel, D. Labavic, Hildegard Meyer-Ortmanns +1
Using numerical methods we discuss the effects of open boundary conditions on condensation phenomena in the zero-range process (ZRP) and transport processes with pair-factorized st…
Stochastic Description of a Bistable Frustrated Unit
Ashok Garai, Bartlomiej Waclaw, Hannes Nagel +1
Mixed positive and negative feedback loops are often found in biological systems which support oscillations. In this work we consider a prototype of such systems, which has been re…
Tuning the shape of the condensate in spontaneous symmetry breaking
B. Waclaw, J. Sopik, W. Janke +1
We investigate what determines the shape of a particle condensate in situations when it emerges as a result of spontaneous breaking of translational symmetry. We consider a model w…
Dynamical Linked Cluster Expansions: A Novel Expansion Scheme for Point-Link-Point-Interactions
H. Meyer-Ortmanns, T. Reisz
Dynamical linked cluster expansions are linked cluster expansions with hopping parameter terms endowed with their own dynamics. This amounts to a generalization from 2-point to poi…
How sharp is the chiral crossover phenomenon for realistic meson masses?
Hildegard Meyer-Ortmanns, Bernd-Jochen Schaefer
The mass dependence of the chiral phase transition is studied in the linear sigma-model to leading order in a -expansion, denoting the number of fl…
Chiral Symmetry Restoration at Finite Temperature in the Linear Sigma--Model
D. Metzger, H. Meyer--Ortmanns, H. --J. Pirner
The temperature behaviour of meson condensates and is calculated in the -linear sigma model. The couplings of the Lagrangian are fitted to the ph…
