Popcorn in the sky: Identifying primordial black holes in the gravitational-wave background

Primordial black holes (PBHs) are possible sources of a gravitational-wave background (GWB), detectable with the next observing runs of LIGO--Virgo--KAGRA. In case of a detection, it will be crucial to distinguish the possible sources of this GWB. One under-explored possibility is to exploit the duty cycle that quantifies the number...

Phase transition, phase separation and mode softening of a two-component Bose-Einstein condensate in an optical cavity

We investigate the superradiant phase transition in a two-component Bose-Einstein condensate with distinct atomic detunings, confined in an optical cavity and driven by a transverse pump laser. By combining perturbation theory and numerical simulations, we demonstrate that the phase transition is dominated by the red-detuned...

Spacetime Quasicrystals

Self-similar quasicrystals (like the famous Penrose and Ammann-Beenker tilings) are exceptional geometric structures in which long-range order, quasiperiodicity, non-crystallographic orientational symmetry, and discrete scale invariance are tightly interwoven in a beautiful way. In this paper, we show how such structures may be...

Single Production of a Vector-Like Top as a Probe of Charged Higgs Bosons at a Muon-Proton Collider

We investigate the discovery prospects for a vector-like top partner ($T$) within the Type-II Two-Higgs-Doublet Model (2HDM-II) at future high-energy $μp$ colliders. The analysis focuses on the charged Higgs decay mode $μ^+ p \to ν_μ\, \bar{b}T \to ν_μ\, \bar{b}H^+b$, with the subsequent decay $H^+\to t\bar{b}$ yielding a final state...

Learning to bin: differentiable and Bayesian optimization for multi-dimensional discriminants in high-energy physics

Categorizing events using discriminant observables is central to many high-energy physics analyses. Yet, bin boundaries are often chosen by hand. A simple, popular choice is to apply argmax projections of multi-class scores and equidistant binning of one-dimensional discriminants. We propose a binning optimization for signal...

PFT: Phonon Fine-tuning for Machine Learned Interatomic Potentials

We introduce phonon fine-tuning (PFT),...
