Constraining primordial non-Gaussianity and energy injection with the thermal Sunyaev-Zeldovich effect and integrated Sachs-Wolfe effect cross-correlation
Ayodeji Ibitoye, Yin-Zhe Ma, Prabhakar Tiwari
Constraining primordial non-Gaussianity (PNG) provides key insights into the physics of cosmic inflation and the initial conditions of the Universe, which remain central topics in…
Inverse Feshbach's problem: Solvability and solutions
Miloslav Znojil
Given a certain specific, by matrix form of the Feshbach's effective (i.e., energy-dependent) Hamiltonian , the inverse-problem reconstruction of the…
The Inbound Gas and Dust Evolution of Interstellar Comet 3I/ATLAS from Optical Spectroscopy and Multi-band Photometry
Toni Santana-Ros, Alexey Sergeyev, Oleksandra Ivanova +9
Interstellar objects (ISOs) provide direct constraints on the composition and evolution of extrasolar planetary systems. As the third confirmed ISO, comet 3I/ATLAS offers a rare op…
Lecture notes on classical and quantum non-Markovianity
Graeme Pleasance
The study of non-Markovian quantum processes has attracted significant interest in recent decades, giving rise to several competing notions of quantum non-Markovianity. These notes…
Optimising Trotter-Suzuki Simulations of Markovian Open Quantum Systems via Classical Search
S. M. Pillay, I. J. David, I. Sinayskiy +1
Simulating an open quantum system on a digital quantum computer often involves the use of Trotter-Suzuki (TS) Product Formulas (PF) to approximate the system's time evolution. Prec…
Global 21cm Measurement Calibration Methodology
Martin Bucher, Christian J. Kirkham, Eloy de Lera Acedo +2
21cm global signal observations present a unique set of calibration challenges owing to the absolute character of the required measurement. Since differential measurements on the s…
