Supernova Siblings and their Parent Galaxies in the Zwicky Transient Facility Bright Transient Surve

M. L. Graham, C. Fremling, D. A. Perley +19

Supernova (SN) siblings -- two or more SNe in the same parent galaxy -- are useful tools for exploring progenitor stellar populations as well as properties of the host galaxies suc…

Observation of coherent coupling between super- and subradiant states of an ensemble of cold atoms collectively coupled to a single propagating optical mode

Riccardo Pennetta, Daniel Lechner, Martin Blaha +3

We discuss the evolution of the quantum state of an ensemble of atoms that are coupled via a single propagating optical mode. We theoretically show that the quantum state of N atom…

Basin sizes depend on stable eigenvalues in the Kuramoto model

Antonio Mihara, Michael Zaks, Elbert E. N. Macau +1

We show that for the Kuramoto model (with identical phase oscillators equally coupled) its global statistics and size of the basins of attraction can be estimated through the eigen…

Revisiting the no-boundary proposal with a scalar field

Caroline Jonas, Jean-Luc Lehners, Vincent Meyer

Recent works have suggested that the no-boundary proposal should be defined as a sum over regular, not necessarily compact, metrics. We show that such a prescription can be impleme…

Chirality of Valley Excitons in Monolayer Transition-Metal Dichalcogenides

Fabio Caruso, Maximilian Schebek, Yiming Pan +2

By enabling control of valley degrees of freedom in transition-metal dichalcogenides, valley-selective circular dichroism has become a key concept in valleytronics. In this manuscr…

Combinatorial Solution of the Eclectic Spin Chain

Changrim Ahn, Luke Corcoran, Matthias Staudacher

The one-loop dilatation operator in the holomorphic 3-scalar sector of the dynamical fishnet theory is studied. Due to the non-unitary nature of the underlying field theory this op…

The higher-dimensional origin of five-dimensional gauged supergravities

Gregoire Josse, Emanuel Malek, Michela Petrini +1

Using exceptional generalised geometry, we classify which five-dimensional gauged supergravities can arise as a consistent truncation of 10-/11-dimensional supergravit…

Rashba and Dresselhaus effects in 2D Pb-I-based perovskites

Benedikt Maurer, Christian Vorwerk, Claudia Draxl

Bulk hybride halide perovskites are governed by significant Rashba and Dresselhaus splitting. This indicates that such effects will not only affect their optoelectronic properties…

Chromo-electric screening length in 2+1 flavor QCD

Peter Petreczky, Sebastian Steinbeißer, Johannes Heinrich Weber

We study Polyakov loop as well as correlators of real and imaginary parts of the Polyakov loop in 2+1 flavor QCD at finite temperature. We use hypercubic (HYP) smearing to improve…

Wading through the void: Exploring quantum friction and nonequilibrium fluctuations

Daniel Reiche, Francesco Intravaia, Kurt Busch

When two or more objects move relative to one another in vacuum, they experience a drag force which, at zero temperature, usually goes under the name of quantum friction. This cont…

Holographic Evidence for Non-Supersymmetric Conformal Manifolds

Alfredo Giambrone, Adolfo Guarino, Emanuel Malek +3

We provide the first holographic evidence for the existence of a non-supersymmetric conformal manifold arising from exactly marginal but supersymmetry-breaking deformations of a su…

Track reconstruction and matching between emulsion and silicon pixel detectors for the SHiP-charm experiment

SHiP Collaboration

In July 2018 an optimization run for the proposed charm cross section measurement for SHiP was performed at the CERN SPS. A heavy, moving target instrumented with nuclear emulsion…

The seeds of EFT double copy

Quentin Bonnefoy, Gauthier Durieux, Christophe Grojean +2

We explore the double copy of effective field theories (EFTs), in the recently proposed generalized color-kinematics and Kawai-Lewellen-Tye (KLT) approaches. In the former, we syst…

Ab initio simulation of laser-induced electronic and vibrational coherence

Jannis Krumland, Matheus Jacobs, Caterina Cocchi

The atomistic resolution recently achieved by ultrafast spectroscopies demands corresponding theoretical advances. Real-time time-dependent density-functional theory (RT-TDDFT) wit…

Multipoint correlators on the supersymmetric Wilson line defect CFT

Julien Barrat, Pedro Liendo, Giulia Peveri +1

We study multipoint correlators of protected scalars on the Maldacena-Wilson line in SYM. Working at weak coupling in the planar limit, we derive an explicit recurs…

Measuring the stability of fundamental constants with a network of clocks

G. Barontini, L. Blackburn, V. Boyer +41

The detection of variations of fundamental constants of the Standard Model would provide us with compelling evidence of new physics, and could lift the veil on the nature of dark m…

Role of Spin-Orbit Coupling in High-order Harmonic Generation Revealed by Super-Cycle Rydberg Trajectories

Nicola Mayer, Samuel Beaulieu, Alvaro Jimenez-Galan +7

High-harmonic generation is typically thought of as a sub-laser-cycle process, with the electron's excursion in the continuum lasting a fraction of the optical cycle. However, it w…

Imprinting chirality on atoms using synthetic chiral light fields
