Lie symmetries of semi-linear Schrödinger equations and applications
Stoimen Stoimenov, Malte Henkel
Conditional Lie symmetries of semi-linear 1D Schrödinger and diffusion equations are studied if the mass (or the diffusion constant) is considered as an additional variable. In thi…
Supersymmetric extensions of Schrödinger-invariance
Malte Henkel, Jeremie Unterberger
The set of dynamic symmetries of the scalar free Schrödinger equation in d space dimensions gives a realization of the Schrödinger algebra that may be extended into a representatio…
On the dynamical symmetric algebra of ageing: Lie structure, representations and Appell systems
Malte Henkel, Rene Schott, Stoimen Stoimenov +1
The study of ageing phenomena leads to the investigation of a maximal parabolic subalgebra of conf_3 which we call alt. We investigate its Lie structure, prove some results concern…
Local scale-invariances in the bosonic contact and pair-contact processes
Florian Baumann, Stoimen Stoimenov, Malte Henkel
Local scale-invariance for ageing systems without detailed balance is tested through studying the dynamical symmetries of the critical bosonic contact process and the critical boso…
Reply to "Comment on 'Scaling of the linear response in simple ageing systems without disorder' "
Malte Henkel, Michel Pleimling
The value of the non-equilibrium exponent is measured in the two-dimensional (2D) Ising model quenched to below criticality from the dynamical scaling of the zero-field-cooled…
Persistent current and Drude weight in mesoscopic rings
F. Carvalho Dias, I. R. Pimentel, M. Henkel
We study the persistent current and the Drude weight of a system of spinless fermions, with repulsive interactions and a hopping impurity, on a mesoscopic ring pierced by a magneti…
Dynamical symmetries of semi-linear Schrödinger and diffusion equations
Stoimen Stoimenov, Malte Henkel
Conditional and Lie symmetries of semi-linear 1D Schrödinger and diffusion equations are studied if the mass (or the diffusion constant) is considered as an additional variable. In…
Ageing without detailed balance in the bosonic contact and pair-contact processes: exact results
Florian Baumann, Malte Henkel, Michel Pleimling +1
Ageing in systems without detailed balance is studied in the exactly solvable bosonic contact process and the critical bosonic pair-contact process. The two-time correlation functi…
Phase-ordering kinetics: ageing and local scale-invariance
Malte Henkel
Dynamical scaling in ageing systems, notably in phase-ordering kinetics, is well-established. New evidence in favour of Galilei-invariance in phase-ordering kinetics is reviewed.
