Systematic interpolatory ansatz for one-dimensional polaron systems
E. J. Lindgren, R. E. Barfknecht, N. T. Zinner
We explore a new variational principle for studying one-dimensional quantum systems in a trapping potential. We focus on the Fermi polaron problem, where a single distinguishable i…
An interpolatory ansatz captures the physics of one-dimensional confined Fermi systems
M. E. S. Andersen, A. S. Dehkharghani, A. G. Volosniev +2
Interacting one-dimensional quantum systems play a pivotal role in physics. Exact solutions can be obtained for the homogeneous case using the Bethe ansatz and bosonisation techniq…
Black hole formation from point-like particles in three-dimensional anti-de Sitter space
E. J. Lindgren
We study collisions of many point-like particles in three-dimensional anti-de Sitter space, generalizing the known result with two particles. We show how to construct exact solutio…
Holographic thermalization in a top-down confining model
B. Craps, E. J. Lindgren, A. Taliotis
It is interesting to ask how a confinement scale affects the thermalization of strongly coupled gauge theories with gravity duals. We study this question for the AdS soliton model,…
Gravitational infall in the hard wall model
B. Craps, E. J. Lindgren, A. Taliotis +2
An infalling shell in the hard wall model provides a simple holographic model for energy injection in a confining gauge theory. Depending on its parameters, a scalar shell either c…
Fermionization of two-component few-fermion systems in a one-dimensional harmonic trap
E. J. Lindgren, J. Rotureau, C. Forssén +2
The nature of strongly interacting Fermi gases and magnetism is one of the most important and studied topics in condensed-matter physics. Still, there are many open questions. A ce…
