Correlation between gravitational wave frequencies as a signature of new black hole physics
Ngo Phuc Duc Loc
We point out that for black holes (BH) of the same mass, despite of arising from two entirely different physical arguments, the peak frequency of the coarse-grained gravitational w…
Constraining regular primordial black holes with isocurvature gravitational waves
Ngo Phuc Duc Loc
We find the constraint on the population of ultra-light regular primordial black holes (RPBHs) by using isocurvature gravitational waves (GW). If ultra-light RPBHs dominated the ea…
Dark matter production from evaporation of regular primordial black holes
Ngo Phuc Duc Loc
We point out that a simple redefinition of the regularizing parameter in regular black hole (RBH) metrics can preserve the self-similarity of the evaporation process. This implies…
Gravitational wave signatures of primordial black hole accretion during early matter domination
Rouzbeh Allahverdi, James B. Dent, Ngo Phuc Duc Loc +1
We present a scenario in which primordial black holes (PBHs) form in a post-inflationary radiation-dominated (RD) phase and then experience significant accretion during a phase of…
Dark matter from mediator decay in early matter domination
Rouzbeh Allahverdi, Ngo Phuc Duc Loc, Jacek K. Osiński
We study dark matter production from mediator decays in scenarios with an epoch of early matter domination. Particles that mediate interactions between dark matter and the standard…
Insights of quantum time into quantum evolution
Ngo Phuc Duc Loc
If time is emergent, quantum system is entangled with quantum time as it evolves. If the system contains entanglement within itself, which we can call internal entanglement to dist…
Time-System Entanglement and Special Relativity
Ngo Phuc Duc Loc
We know that space and time are treated almost equally in classical physics, but we also know that this is not the case for quantum mechanics. A quantum description of both space a…
Unitary paradox of cosmological perturbations
Ngo Phuc Duc Loc
If we interpret the Bekenstein-Hawking entropy of the Hubble horizon as thermodynamic entropy, then the entanglement entropy of the superhorizon modes of curvature perturbation ent…
Shaft inflation in Randall-Sundrum model
Ngo Phuc Duc Loc
Shaft inflation is a model in which the inflaton potential approaches a plateau far from the origin, while it resembles chaotic inflation near the origin. Meanwhile, the Randall-Su…
Dark Matter and Baryogenesis from Visible-Sector Long-Lived Particles
Rouzbeh Allahverdi, Ngo Phuc Duc Loc, Jacek K. Osiński
We present a minimal extension of the standard model that includes a long-lived fermion with weak-scale mass and an fermionic dark matter candidate both of wh…
Sphaleron bound in some nonstandard cosmology scenarios
Ngo Phuc Duc Loc
In the first scenario, we revise the upper bound of the cutoff scale of the dimension-six potential Higgs operator required for a successful electroweak baryogenesis in the case of…
Constraint on the Higgs-Dilaton potential via Warm inflation in Two-Time Physics
Vo Quoc Phong, Ngo Phuc Duc Loc
Within the symmetry, the Two-time model (2T model) has six dimensions with two dimensions of time and the dilaton field that can be identified as inflaton in a warm infla…
