Landau quantization of high-fold fermions in honeycomb lattices
Luisa Madail, Joaquín Fernández-Rossier
We present the theory of the Landau levels of high-fold fermions in honeycomb lattices. These fermions arise as a generalization of the tight-binding model in a honeycomb lat…
A Fully Analytic Expression for the 2PN N-Body Hamiltonian
Felix M. Heinze, Gerhard Schäfer, Bernd Brügmann
We present a complete analytic expression for the -body Hamiltonian of nonspinning point particles at second post-Newtonian (2PN) order in the Arnowitt-Deser-Misner (ADM) gauge.…
The N-Body 2PN Hamiltonian and Numerical Integration of the Equations of Motion
Felix M. Heinze, Gerhard Schäfer, Bernd Brügmann
To date, the second-order post-Newtonian (2PN) Hamiltonian has been known in closed analytic form only for systems of up to three point masses. In this paper, we present an analyti…
Exploring the Dynamics of General Relativistic Binary-Single and Binary-Binary Encounters of Black Holes
Felix M. Heinze, Bernd Brügmann, Tim Dietrich +1
In this exploratory study, we demonstrate the capability of the numerical-relativity code BAM to simulate fully relativistic black-hole binary-single and binary-binary encounters.…
Detecting low-mass haloes with strong gravitational lensing II: constraints on the density profiles of two detected subhaloes
Giulia Despali, Felix M. Heinze, Christopher D. Fassnacht +3
Strong gravitational lensing can detect the presence of low-mass haloes and subhaloes through their effect on the surface brightness of lensed arcs. We carry out an extended analys…
Gravitational lenses in hydrodynamical simulations
Giulia Despali, Felix M. Heinze, Claudio Mastromarino
The gravitational lensing signal produced by a galaxy or a galaxy cluster is determined by its total matter distribution, providing us with a way to directly constrain their dark m…
Not All Subhaloes Are Created Equal: Modelling the Diversity of Subhalo Density Profiles in TNG50
Felix M. Heinze, Giulia Despali, Ralf S. Klessen
In this work, we analyse the density profiles of subhaloes with masses M in the TNG50 simulation, with the aim of including baryonic ef…
