Dynamical Dark Energy, Dual Spacetime, and DESI
Sunhaeng Hur, Vishnu Jejjala, Michael J. Kavic +2
In this paper we discuss possible consequences of a manifestly non-commutative and -duality covariant formulation of string theory on dark energy, when the correspondence betwee…
Searching for cosmic strings via black hole spin-down
Sameer Ahmed, Michael J. Kavic, Steven L. Liebling +3
Cosmic strings that are attached to rapidly spinning black holes can extract significant amounts of rotational energy and angular momentum. Here we study the effect on primordial b…
Stability and Observability of Magnetic Primordial Black Hole-Neutron Star Collisions
John Estes, Michael Kavic, Steven L. Liebling +2
The collision of a primordial black hole with a neutron star results in the black hole eventually consuming the entire neutron star. However, if the black hole is magnetically char…
First Principles Phenomenology of
Vishnu Jejjala, Michael Kavic, Djordje Minic +1
In this letter we discuss infinite statistics and motivate its role in quantum gravity. Then, we connect infinite statistics to a dynamical form of dark energy, and we obtain an ex…
Quantum Gravity and Phenomenology: Dark Matter, Dark Energy, Vacuum Selection, Emergent Spacetime, and Wormholes
Per Berglund, De-Chang Dai, Douglas Edmonds +9
We discuss the relevance of quantum gravity to the frontier questions in high energy phenomenology: the problems of dark matter, dark energy, and vacuum selection as well as the pr…
Dynamical Dark Energy and Infinite Statistics
Vishnu Jejjala, Michael J. Kavic, Djordje Minic +1
In the CDM model, dark energy is viewed as a constant vacuum energy density, the cosmological constant in the Einstein--Hilbert action. This assumption can be relaxed in various…
A sensitive search for wormholes
John H. Simonetti, Michael J. Kavic, Djordje Minic +2
The realm of strong classical gravity and perhaps even quantum gravity are waiting to be explored. In this letter we consider the recently detected triple system composed of two st…
Quantum gravity & BH-NS binaries
Michael J. Kavic, Djordje Minic, John Simonetti
We argue that the Black Hole-Neutron Star (BH-NS) binaries are the natural astrophysical probes of quantum gravity in the context of the new era of multi-messenger astronomy. In pa…
Probing Near-Horizon Fluctuations with Black Hole Binary Mergers
Steven L. Liebling, Michael Kavic, Matthew Lippert
The strong version of the nonviolent nonlocality proposal of Giddings predicts "strong but soft" quantum metric fluctuations near black hole horizons in an attempt to resolve the i…
Analysis of Scattering from Archival Pulsar Data using a CLEAN-based Method
Jr-Wei Tsai, John H. Simonetti, Michael Kavic
In this work we adopted a CLEAN-based method to determine the scatter time, , from archived pulsar profiles under both the thin screen and uniform medium scattering models and t…
Constraining the Rate of Primordial Black-Hole Explosions and Extra Dimension Scale using a Low-Frequency Radio Antenna Array
Sean E. Cutchin, John H. Simonetti, Steven W. Ellingson +2
An exploding primordial black-hole (PBH) may produce a single pulse of electromagnetic radiation detectable at the low-frequency end of the radio spectrum. Furthermore, a radio tra…
The Big Bang as the Ultimate Traffic Jam
Vishnu Jejjala, Michael Kavic, Djordje Minic +1
We present a novel solution to the nature and formation of the initial state of the Universe. It derives from the physics of a generally covariant extension of Matrix theory. We fo…
