Wading the String Bog: CMB Birefringence in the Swampland
Guido D'Amico, Nemanja Kaloper, Alexander Westphal
We point out that observations of cosmic birefringence may provide direct experimental tests of Swampland conjectures. Ultralight scalar field birefringence mechanisms are constrai…
Very-High-Frequency Gravitational Waves from Multi-Monodromy Inflation
Guido D'Amico, Andrew A. Geraci, Nemanja Kaloper +1
We show that in multi-stage axion monodromy inflation an interruption near the end of the penultimate stage can lead to a spike in the gravitational wave background. These gravitat…
Falsifying Anthropics
Nemanja Kaloper, Alexander Westphal
We propose using fuzzy axion dark matter to test the anthropic principle. A very light axion can be directly detectable, at least by black hole superradiance effects. The idea then…
Implications of Weak Gravity Conjecture for de Sitter Decay by Flux Discharge
Nemanja Kaloper, Alexander Westphal
We examine implications of the weak gravity conjecture for the mechanisms for discharging cosmological constant via membrane nucleations. Once screening fluxes and membranes which…
Study of the neutron quantum states in the gravity field
V. V. Nesvizhevsky, A. K. Petukhov, H. G. Boerner +9
We have studied neutron quantum states in the potential well formed by the earth's gravitational field and a horizontal mirror. The estimated characteristic sizes of the neutron wa…
