Asymptotic aspects of the Teichmüller TQFT

Jørgen Ellegaard Andersen, Jens-Jakob Kratmann Nissen

We calculate the knot invariant coming from the Teichmüller TQFT [AK1]. Specifically we calculate the knot invariant for the complement of the knot both in the original [AK1]…

A Type II Supernova Hubble diagram from the CSP-I, SDSS-II, and SNLS surveys

T. de Jaeger, S. González-Gaitán, M. Hamuy +15

The coming era of large photometric wide-field surveys will increase the detection rate of supernovae by orders of magnitude. Such numbers will restrict spectroscopic follow-up in…

High-order harmonic generation from gapped graphene: perturbative response and transition to non-perturbative regime

Darko Dimitrovski, Lars Bojer Madsen, Thomas Garm Pedersen

We consider the interaction of gapped graphene in the two-band approximation using an explicit time-dependent approach. In addition to the full high-order harmonic generation (HHG)…

A New Method for the Asteroseismic Determination of the Evolutionary State of Red-Giant Stars

Yvonne Elsworth, Saskia Hekker, Sarbani Basu +1

Determining the ages of red-giant stars is a key problem in stellar astrophysics. One of the difficulties in this determination is to know the evolutionary state of the individual…

Do A-type stars flare?

M. G. Pedersen, V. Antoci, H. Korhonen +5

For flares to be generated, stars have to have a sufficiently deep outer convection zone (F5 and later), strong large--scale magnetic fields (Ap/Bp-type stars) or strong, radiative…

Time-dependent restricted-active-space self-consistent-field theory for bosonic many-body systems

Camille Lévêque, Lars Bojer Madsen

We describe the time-dependent restricted-active-space self-consistent-field (TD-RASSCF) method for a system of interacting bosons. We provide the theory of the method and discuss…

Optical photometry and spectroscopy of the low-luminosity, broad-lined Ic supernova iPTF15dld

E. Pian, L. Tomasella, E. Cappellaro +37

Core-collapse stripped-envelope supernova (SN) explosions reflect the diversity of physical parameters and evolutionary paths of their massive star progenitors. We have observed th…

Non-Sequential Double Recombination High Harmonic Generation in Molecular-like Systems

Kenneth K. Hansen, Lars Bojer Madsen

We present a study of non-sequential double recombination (NSDR) high harmonic generation (HHG) in a molecular-like system. Using a Coulomb-corrected three-step model we are able t…

How structure sculpts function: unveiling the contribution of anatomical connectivity to the brain's spontaneous correlation structure

Ruggero G. Bettinardi, Gustavo Deco, Vasilis M. Karlaftis +5

Intrinsic brain activity is characterized by highly structured co-activations between different regions, whose origin is still under debate. In this paper, we address the question…

A Mathematical Analysis of Dressed Photon in Ground State of Generalized Quantum Rabi Model Using Pair Theory

Masao Hirokawa, Jacob Schach Moller, Itaru Sasaki

We consider the generalized quantum Rabi model with the so-called -term in the light of the Hepp-Lieb-Preparata quantum phase transition. We investigate the dressed photon i…

Laser-induced dissociative ionization of H from the near-infrared to the mid-infrared regime

Qingli Jing, Lars Bojer Madsen

We apply the Monte Carlo Wave Packet (MCWP) approach to investigate the kinetic energy release (KER) spectra of the protons following double ionization in H when interacting…

Ages of 70 dwarfs of three populations in the solar neighborhood: considering O and C abundances in stellar models

Z. S. Ge, S. L. Bi, Y. Q. Chen +5

Oxygen and carbon are important elements in stellar populations. Their behavior refers to the formation history of the stellar populations. C and O abundances would also obviously…

Gaia's view of the Boo star puzzle

Simon J. Murphy, Ernst Paunzen

The evolutionary status of the chemically peculiar class of Boo stars has been intensely debated. It is now agreed that the Boo phenomenon affects A stars of all ages, from…

Standing on the shoulders of Dwarfs: the Kepler asteroseismic LEGACY sample II - radii, masses, and ages

Victor Silva Aguirre, Mikkel N. Lund, H. M. Antia +21

We use asteroseismic data from the Kepler satellite to determine fundamental stellar properties of the 66 main-sequence targets observed for at least one full year by the mission.…

Non-local thermodynamic equilibrium stellar spectroscopy with 1D and 3D models - II. Chemical properties of the Galactic metal-poor disc and the halo

Maria Bergemann, Remo Collet, Ralph Schoenrich +5

From exploratory studies and theoretical expectations it is known that simplifying approximations in spectroscopic analysis (LTE, 1D) lead to systematic biases of stellar parameter…

An empirical and theoretical critique of the Euclidean index

Jens Peter Andersen

The recently proposed Euclidean index offers a novel approach to measure the citation impact of academic authors, in particular as an alternative to the h-index. We test if the ind…
