Towards a Digital Twin of Noisy Quantum Computers: Calibration-Driven Emulation of Transmon Qubits

Kavli Affiliate: Elise Jennings | First 5 Authors: Ronny Müller, Maximilian Zanner, Mika Schielein, Martin Rüfenacht, Elise Jennings | Summary: We develop a parametric error model to construct a digital twin of a superconducting transmon qubit device. The model parameters are extracted from hardware calibration data and supplementary benchmarking circuits, providing a dynamic, system-specific representation […]

The DECam MAGIC Survey: A Wide-field Photometric Metallicity Study of the Sculptor Dwarf Spheroidal Galaxy

Kavli Affiliate: Alexander Ji | First 5 Authors: Fabrícia O. Barbosa, Anirudh Chiti, Guilherme Limberg, Andrew Pace, William Cerny | Summary: The metallicity distribution function and internal chemical variations of a galaxy are fundamental to understand its formation and assembly history. In this work, we analyze photometric metallicities for 3883 stars over seven half-light radii […]

Self Consistent Thermal Resummation: A Case Study of the Phase Transition in 2HDM

Kavli Affiliate: Carlos E. M. Wagner | First 5 Authors: Pedro Bittar, Subhojit Roy, Carlos E. M. Wagner, , | Summary: An accurate description of the scalar potential at finite temperature is crucial for studying cosmological first-order phase transitions (FOPT) in the early Universe. At finite temperatures, a precise treatment of thermal resummations is essential, […]

Interference with Gravitational Instability: Hot and Fuzzy Dark Matter

Kavli Affiliate: Wayne Hu | First 5 Authors: Rayne Liu, Wayne Hu, Huangyu Xiao, , | Summary: Wave or fuzzy dark matter produced with high momenta behaves in many ways like hot particle dark matter while also possessing seemingly different phenomenology due to wave interference. We develop wave perturbation theory to show that white noise […]

Wave Interference in Self-Interacting Fuzzy Dark Matter

Kavli Affiliate: Wayne Hu | First 5 Authors: Christian Capanelli, Wayne Hu, Evan McDonough, , | Summary: In the Fuzzy Dark Matter (FDM) scenario, the dark matter is composed of an ultra-light scalar field with coherence length and wave interference on astrophysical scales. Scalar fields generically have quartic self-interactions that modify their dispersion relation and […]

Flipping of the tidal tails of the Ophiuchus stream due to the decelerating Galactic bar

Kavli Affiliate: Alexander P. Ji | First 5 Authors: Yong Yang, Geraint F. Lewis, Denis Erkal, Ting S. Li, Andrew P. Li | Summary: The Ophiuchus stellar stream presents a puzzle due to its complicated morphology, with a substructure perpendicular to the main track (spur), a broadened tail (fanning), and a shorter than expected angular […]

Observing Dark Matter Decays to Gravitons via Graviton-Photon Conversion

Kavli Affiliate: Gordan Krnjaic | First 5 Authors: David I. Dunsky, Gordan Krnjaic, Elena Pinetti, , | Summary: Since dark matter is only known to have gravitational interactions, it may plausibly decay to gravitons on cosmological timescales. Although such a scenario can be easily realized, there are currently no known limits on this possibility based […]
