Suppressed Quantum Effects of Weakly Coupled Waves
Yunjia Bao, Dhong Yeon Cheong, Nicholas L. Rodd +3
The paper analyzes why quantum signatures of weakly coupled waves such as axion dark matter and gravitational radiation are extremely hard to detect, showing that detector coarse‑g…
Kinetic Isocurvature Perturbation
Kyu Jung Bae, Dhong Yeon Cheong, Jinn-Ouk Gong +2
We formulate a new class of primordial perturbations called , where the mass density of dark matter is constant relative to the photon…
Composite Hybrid Inflation : Primordial Black Holes and Stochastic Gravitational Waves
Giacomo Cacciapaglia, Dhong Yeon Cheong, Aldo Deandrea +4
We investigate the production of primordial black holes and gravitational waves in composite hybrid inflation. Starting from an effective chiral Lagrangian with a dilaton and pions…
Beyond the Starobinsky model after ACT
Min Gi Park, Dhong Yeon Cheong, Seong Chan Park
We revisit higher order corrections to the Starobinsky inflationary model using the most recent P-ACT-LB-BK18 data, which exhibits a mild but definite tension with the predictions…
Intrinsically Quantum Effects of Axion Dark Matter are Undetectable
Yunjia Bao, Dhong Yeon Cheong, Nicholas L. Rodd +3
Is the usual treatment of axion dark matter as a classical field reliable? We show that the answer is subtle: the axion field could well be in a quantum state that has no complete…
A Quantum Description of Wave Dark Matter
Dhong Yeon Cheong, Nicholas L. Rodd, Lian-Tao Wang
We outline a fundamentally quantum description of bosonic dark matter (DM) from which the conventional classical-wave picture emerges in the limit . As approp…
