Challenges in Interpreting the NANOGrav 15-Year Data Set as Early Universe Gravitational Waves Produced by ALP Induced Instability
Michael Geller, Subhajit Ghosh, Sida Lu +1
In this paper, we study a possible early universe source for the recent observation of a stochastic gravitational wave background at the NANOGrav pulsar timing array. The source is…
A new source for light dark matter isocurvature in low scale inflation
Andrea Caputo, Michael Geller, Giuseppe Rossi
Light scalar and pseudoscalar particles are compelling dark matter candidates, with a vast running experimental program to discover them. Previous studies have shown that these lig…
Relevant Dilaton Stabilization
Csaba Csáki, Michael Geller, Zamir Heller-Algazi +1
We propose a simple modification of the Goldberger-Wise mechanism for stabilizing the scale of spontaneously broken conformal theories. The source of explicit conformal symmetry br…
Boosting Asymmetric Charged DM via Thermalization
Michael Geller, Zamir Heller-Algazi
We consider a dark sector scenario with two dark matter species with opposite dark charges and an asymmetric population comprising some fraction of the dark matter abundance…
Quantum algorithm for Wang-Landau sampling
Garrett T. Floyd, David P. Landau, Michael R. Geller
It has been shown that the Metropolis algorithm can be implemented on quantum computers in a way that avoids the sign problem. However, flat histogram techniques are often preferre…
Nonlinear and non-CP gates for Bloch vector amplification
Michael R. Geller
Any state r = (x,y,z) of a qubit, written in the Pauli basis and initialized in the pure state r = (0,0,1), can be prepared by composing three quantum operations: two unitary rotat…
