Design of ALPHA Phase I: A Plasma Haloscope for 10--20 GHz Post-Inflation Axions

ALPHA Collaboration, Xiran Bai, Rustam Balafendiev +53

The axion is a well-motivated hypothetical particle capable of resolving both the strong CP problem and the dark matter mystery, with recent post-inflationary cosmological simulati…

The Glow of Axion Quark Nugget Dark Matter: (IV) CMB Spectral and Anisotropy Signatures

Fereshteh Majidi, Xunyu Liang, Michael Sekatchev +2

Axion quark nuggets (AQNs) are macroscopic dark-matter candidates, with masses of the order of a few grams to a kilogram and sub-micron radius, thought to form at the Quantum Chrom…

The Glow of Axion Quark Nugget Dark Matter: (III) The Mysteries of the Milky Way UV Background

Michael Sekatchev, Xunyu Liang, Fereshteh Majidi +3

Axion quark nuggets (AQNs) are hypothetical objects with nuclear density that would have formed during the quark-hadron transition and could make up most of the dark matter today.…

Stochastic Approaches to Asset Price Analysis

Michael Sekatchev, Zhengxiang Zhou

In this project, we propose to explore the Kalman filter's performance for estimating asset prices. We begin by introducing a stochastic mean-reverting processes, the Ornstein-Uhle…

The Glow of Axion Quark Nugget Dark Matter: (I) Large Scale Structures

Fereshteh Majidi, Xunyu Liang, Ludovic Van Waerbeke +5

Axion quark nuggets (AQNs) are hypothetical objects with a mass greater than a few grams and sub-micrometer size, formed during the quark-hadron transition. Originating from the ax…
