Stochastic ultralight dark matter fluctuations in pulsar timing arrays

H Kim, A Mitridate - Physical Review D, 2024 - APS
Metric perturbations induced by ultralight dark matter (ULDM) fields have long been
identified as a potential target for pulsar timing array (PTA) observations. Previous works …

Search for dark-matter-induced oscillations of fundamental constants using molecular spectroscopy

R Oswald, A Nevsky, V Vogt, S Schiller, NL Figueroa… - Physical review …, 2022 - APS
A possible implication of an ultralight dark matter field interacting with the standard model
degrees of freedom is oscillations of fundamental constants. Here, we establish direct …

Improved bounds on ultralight scalar dark matter in the radio-frequency range

O Tretiak, X Zhang, NL Figueroa, D Antypas, A Brogna… - Physical review …, 2022 - APS
We present a search for fundamental constant oscillations in the range 20 kHz–100 MHz
that may arise within models for ultralight dark matter (UDM). Using two independent optical …

Functional nanoscale phase separation and intertwined order in quantum complex materials

G Campi, A Bianconi - Condensed Matter, 2021 - mdpi.com
Nanoscale phase separation (NPS), characterized by particular types of correlated
disorders, plays an important role in the functionality of high-temperature superconductors …

Probing primordial black holes and dark matter clumps in the Solar System with gravimeter and Global Navigation Satellite Systems networks

M Cuadrat-Grzybowski, S Clesse, P Defraigne… - Physical Review D, 2024 - APS
We show that the Global Navigation Satellite System (GNSS) and gravimeters on Earth and
in space can potentially offer the most accurate direct measurement of local density of near …

Probing a local dark matter halo with neutrino oscillations

T Gherghetta, A Shkerin - Physical Review D, 2023 - APS
Dark matter particles can form halos gravitationally bound to massive astrophysical objects.
The Earth could have such a halo where depending on the particle mass, the halo either …

Charge Density Waves in Probed by Resonant X-Ray Scattering under Uniaxial Compression

HH Kim, E Lefrançois, K Kummer, R Fumagalli… - Physical review …, 2021 - APS
We report a comprehensive Cu L 3-edge resonant x-ray scattering (RXS) study of two-and
three-dimensional (2D and 3D) incommensurate charge correlations in single crystals of the …

Searching for dark matter with an optical cavity and an unequal-delay interferometer

E Savalle, A Hees, F Frank, E Cantin, PE Pottie… - Physical Review Letters, 2021 - APS
We propose a new type of experiment that compares the frequency of a clock (an ultrastable
optical cavity in this case) at time t to its own frequency some time tT earlier, by “storing” the …

Constraints on scalar field dark matter from colocated michelson interferometers

L Aiello, JW Richardson, SM Vermeulen, H Grote… - Physical Review Letters, 2022 - APS
Low-mass (sub-eV) scalar field dark matter may induce apparent oscillations of fundamental
constants, resulting in corresponding oscillations of the size and the index of refraction of …

Detecting axion dark matter with black hole polarimetry

X Gan, LT Wang, H **ao - Physical Review D, 2024 - APS
The axion, as a leading dark matter candidate, is the target of many ongoing and proposed
experimental searches based on its coupling to photons. Ultralight axions that couple to …
