Time dependence of entanglement for steady state formation in AdS/CFT
Mario Flory, Johanna Erdmenger, Daniel Fernandez +3
We consider a holographic model of two 1+1-dimensional heat baths at different temperatures joined at time , such that a steady state heat-current region forms and expands in…
On integrable boundaries in the 2 dimensional -models
Ines Aniceto, Zoltan Bajnok, Tamas Gombor +2
We make an attempt to map the integrable boundary conditions for 2 dimensional non-linear O(N) -models. We do it at various levels: classically, by demanding the existence of in…
Could the primordial radiation be responsible for vanishing of topological defects?
Tomasz Romańczukiewicz
We study the motion of topological defects in 1+1 and 2+1 d relativistic model with three equal vacua in the presence of radiation. We show that even small fluctuations can t…
Oscillons in the presence of external potential
Tomasz Romańczukiewicz, Yakov Shnir
We discuss similarity between oscillons and oscillational mode in perturbed . For small depths of the perturbing potential it is difficult to distinguish between oscillons and…
Four-dimensional CDT with toroidal topology
Jan Ambjørn, Jakub Gizbert-Studnicki, Andrzej Görlich +2
3+1 dimensional Causal Dynamical Triangulations (CDT) describe a quantum theory of fluctuating geometries without the introduction of a background geometry. If the topology of spac…
