A directional force template for quadratically coupled ultralight dark matter
Dawid Brzeminski, Aaron Pierce
Quadratic couplings between ultralight scalar dark matter and Standard Model fields can produce a distorted dark-matter field profile around the Earth. Gradients in the field induc…
A Bandpass Axion Or: How I Learned To Stop Worrying About Stars And Love The Lab
Dawid Brzeminski, Anson Hook
Axion-like particles coupled to photons are one of the most compelling new physics scenarios. We demonstrate that an axion-photon coupling resulting from a non-anomalous PQ symmetr…
Narrowing Down Sources of High-Frequency Gravitational Waves
Asher Berlin, Dawid Brzeminski, Erwin H. Tanin
Detecting gravitational waves above 100 kHz would constitute a major discovery, as any observable signal would have to arise from new physics within the late universe. Although man…
Searching for Ultralight Scalar Dark Matter with Clocks in Low Earth Orbit
Dawid Brzeminski, Aaron Pierce
The density of ultralight dark matter can be modified in the vicinity of macroscopic bodies when the dark matter possesses quadratic couplings to the Standard Model. If these coupl…
Predicting the Dark Matter -- Baryon Abundance Ratio
Abhishek Banerjee, Dawid Brzeminski, Anson Hook
We discuss relaxation solutions to the dark matter - baryon coincidence problem in the context of QCD axion dark matter. In relaxation solutions, a moduli dynamically adjusts the m…
Searching for String Bosenovas with Gravitational Wave Detectors
Dawid Brzeminski, Anson Hook, Junwu Huang +1
We study the phenomenology of string bosenova explosions in vector superradiance clouds around spinning black holes, focusing on the observable consequences in gravitational wave d…
A Dynamical Explanation of the Dark Matter-Baryon Coincidence
Dawid Brzeminski, Anson Hook
The near equality of the dark matter and baryon energy densities is a remarkable coincidence, especially when one realizes that the baryon mass is exponentially sensitive to UV par…
Constraining Vector Dark Matter with Neutrino experiments
Dawid Brzeminski, Saurav Das, Anson Hook +1
Vector Dark Matter (VDM) that couples to lepton flavor (, , ) acts similarly to a chemical potential for the neutrino flavor eigenstates and modifies neutrino oscill…
Searching for a Fifth Force with Atomic and Nuclear Clocks
Dawid Brzeminski, Zackaria Chacko, Abhish Dev +2
We consider the general class of theories in which there is a new ultralight scalar field that mediates an equivalence principle violating, long-range force. In such a framework, t…
Precision Early Universe Cosmology from Stochastic Gravitational Waves
Dawid Brzeminski, Anson Hook, Gustavo Marques-Tavares
The causal tail of stochastic gravitational waves can be used to probe the energy density in free streaming relativistic species as well as measure and beta functions…
A Time-Varying Fine Structure Constant from Naturally Ultralight Dark Matter
Dawid Brzeminski, Zackaria Chacko, Abhish Dev +1
We present a class of models in which the coupling of the photon to an ultralight scalar field that has a time-dependent vacuum expectation value causes the fine structure constant…
Twist decomposition of Drell-Yan structure functions: phenomenological implications
Dawid Brzeminski, Leszek Motyka, Mariusz Sadzikowski +1
The forward Drell--Yan process in scattering at the LHC at TeV is considered. We analyze the Drell--Yan structure functions assuming the dominance of a Compton-l…
