Generation of spin currents by a temperature gradient in a two-terminal device
R. E. Barfknecht, A. Foerster, N. T. Zinner +1
Theoretical and experimental studies of the interaction between spins and temperature are vital for the development of spin caloritronics, as they dictate the design of future devi…
Clusters in Separated Tubes of Tilted Dipoles
Jeremy R. Armstrong, Aksel S. Jensen, Artem G. Volosniev +1
A few-body cluster is a building block of a many-body system in a gas phase provided the temperature at most is of the order of the binding energy of this cluster. Here we illustra…
Quasi-One-Dimensional Few-Body Systems with Correlated Gaussians
M. Wallenius, D. V. Fedorov, A. S. Jensen +1
The theoretical study of ultracold few-body systems is often done using an idealized 1D model with zero range interactions. Here we study these systems using a more realistic 3D mo…
Super Hamiltonian in superspace for incommensurate superlattices and quasicrystals
Manuel Valiente, Callum W. Duncan, Nikolaj T. Zinner
Infinite quasiperiodic arrangements in space, such as quasicrystals, are typically described as projections of higher-dimensional periodic lattices onto the physical dimension. The…
Ion-induced interactions in a Tomonaga-Luttinger liquid
Andreas Bock Michelsen, Manuel Valiente, Nikolaj Zinner +1
We investigate the physics of a Tomonaga-Luttinger liquid of spin-polarized fermions superimposed on an ion chain. This compound system features (attractive) long-range interspecie…
Dynamics of spin and density fluctuations in strongly interacting few-body systems
Rafael Emilio Barfknecht, Angela Foerster, Nikolaj Thomas Zinner
The decoupling of spin and density dynamics is a remarkable feature of quantum one-dimensional many-body systems. In a few-body regime, however, little is known about this phenomen…
