Asteroseismic Inversions for Internal Sound Speed Profiles of Main-sequence Stars with Radiative Cores
Lynn Buchele, Earl P. Bellinger, Saskia Hekker +3
The theoretical oscillation frequencies of even the best asteroseismic models of solar-like oscillators show significant differences from observed oscillation frequencies. Structur…
Communication protocol for a satellite-swarm interferometer
Oliver Nagy, Manish Pandey, Georgios Exarchakos +2
Orbiting low frequency antennas for radio astronomy (OLFAR) that capture cosmic signals in the frequency range below 30MHz could provide valuable insights on our Universe. These wi…
Loss it right: Euclidean and Riemannian Metrics in Learning-based Visual Odometry
Olaya Álvarez-Tuñón, Yury Brodskiy, Erdal Kayacan
This paper overviews different pose representations and metric functions in visual odometry (VO) networks. The performance of VO networks heavily relies on how their architecture e…
Study of cognitive component of auditory attention to natural speech events
Nhan D. T. Nguyen, Kaare Mikkelsen, Preben Kidmose
Event-related potentials (ERP) have been used to address a wide range of research questions in neuroscience and cognitive psychology including selective auditory attention. The rec…
Seismic and spectroscopic analysis of 9 bright red giants observed by Kepler
H. R. Coelho, A. Miglio, T. Morel +21
Photometric time series gathered by space telescopes such as CoRoT and Kepler allow to detect solar-like oscillations in red-giant stars and to measure their global seismic constra…
Edge Laplacians and Edge Poisson Transforms for Graphs
Christian Arends, Jan Frahm, Joachim Hilgert
For a finite graph, we establish natural isomorphisms between eigenspaces of a Laplace operator acting on functions on the edges and eigenspaces of a transfer operator acting on fu…
Electron-correlation induced nonclassicallity of light from high-harmonic generation
Christian Saugbjerg Lange, Thomas Hansen, Lars Bojer Madsen
We study the effect of electron-electron correlations on the quantum state of the light emitted from high-harmonic generation (HHG). The quantum state of the emitted light is obtai…
Active Learning approach to simulations of Strongly Correlated Matter with the Ghost Gutzwiller Approximation
Marius S. Frank, Denis G. Artiukhin, Tsung-Han Lee +4
Quantum embedding (QE) methods such as the Ghost Gutzwiller Approximation (gGA) offer a powerful approach to simulating strongly-correlated systems, but come with the computational…
Parametric Amplification of a Quantum Pulse
Offek Tziperman, Victor Rueskov Christiansen, Ido Kaminer +1
Creating and manipulating quantum states of light requires nonlinear interactions, but while nonlinear optics is inherently multi-mode, quantum optical analyses are often done with…
Quantum Optics with Rydberg Superatoms
Jan Kumlin, Christoph Braun, Christoph Tresp +3
Quantum optics based on highly excited atoms, also known as Rydberg atoms, has cemented itself as a powerful platform for the manipulation of light at the few-photon level. The Ryd…
The uniqueness of the Wiener-Hopf factorisation of Lévy processes and random walks
Leif Döring, Mladen Savov, Lukas Trottner +1
We prove that the spatial Wiener-Hopf factorisation of a Lévy process or random walk without killing is unique.
Squeeze film absolute pressure sensors with sub-millipascal sensitivity
Mohsen Salimi, Robin V. Nielsen, Henrik B. Pedersen +1
We report on the realization of ultrasensitive absolute pressure sensors based on silicon nitride membrane sandwiches. These sandwiches consist in a pair of highly-pretensioned, ul…
Determination and correction of spectral phase from principal component analysis of coherent phonons
Emmanuel B. Amuah, Khalid M. Siddiqui, Maurizio Monti +2
Measuring the spectral phase of a pulse is key for performing wavelength resolved ultrafast measurements in the few femtosecond regime. However, accurate measurements in real exper…
Efficient and robust second-harmonic generation in thin-film lithium niobate using modal phase matching
Mikkel T. Hansen, Emil Z. Ulsig, Fabien Labbe +4
A double-ridge waveguide is designed for efficient and robust second-harmonic generation (SHG) using the thin-film lithium-niobate-on-insulator (LNOI) platform. Perfect phase match…
Poisson approximation of fixed-degree nodes in weighted random connection models
Christian Hirsch, Benedikt Jahnel, Sanjoy Kumar Jhawar +1
We present a process-level Poisson-approximation result for the degree-k vertices in a high-density weighted random connection model with preferential-attachment kernel in the unit…
Data-driven rules for multidimensional reflection problems
Sören Christensen, Asbjørn Holk Thomsen, Lukas Trottner
Over the recent past data-driven algorithms for solving stochastic optimal control problems in face of model uncertainty have become an increasingly active area of research. Howeve…
Exploring beyond-mean-field logarithmic divergences in Fermi-polaron energy
Ragheed Alhyder, Frédéric Chevy, Xavier Leyronas
We perform a diagrammatic analysis of the energy of a mobile impurity immersed in a strongly interacting two component Fermi gas to second order in the impurity-bath interaction. T…
Testing Continuous Spontaneous Localization model with charged macro-molecules
Emil Lenler-Eriksen, Michael Drewsen, Matteo Carlesso
In the last decade, a growing interest has been devoted to models of spontaneous collapse of the wavefunction, known also as collapse models. They coherently solve the well-known q…
Euclid preparation. Modelling spectroscopic clustering on mildly nonlinear scales in beyond-CDM models
Euclid Collaboration, B. Bose, P. Carrilho +229
We investigate the approximations needed to efficiently predict the large-scale clustering of matter and dark matter halos in beyond-CDM scenarios. We examine the normal branch…
A resolution theorem for extriangulated categories with applications to the index
Yasuaki Ogawa, Amit Shah
Quillen's Resolution Theorem in algebraic -theory provides a powerful computational tool for calculating -groups of exact categories. At the level of , this result goes…
The NFA Acceptance Hypothesis: Non-Combinatorial and Dynamic Lower Bounds
Karl Bringmann, Allan Grønlund, Marvin Künnemann +1
We pose the fine-grained hardness hypothesis that the textbook algorithm for the NFA Acceptance problem is optimal up to subpolynomial factors, even for dense NFAs and fixed alphab…
Polynomially Over-Parameterized Convolutional Neural Networks Contain Structured Strong Winning Lottery Tickets
Arthur da Cunha, Francesco d'Amore, Emanuele Natale
The Strong Lottery Ticket Hypothesis (SLTH) states that randomly-initialised neural networks likely contain subnetworks that perform well without any training. Although unstructure…
