Testing high scale supersymmetry via second order gravitational waves / Flores, Marcos M. (UCLA) ; Kusenko, Alexander (UCLA ; CERN ; Tokyo U., IPMU) ; Pearce, Lauren (Penn State U., New Kensington) ; Perez-Gonzalez, Yuber F. (Durham U., IPPP) ; White, Graham (Southampton U.)
Supersymmetry predicts multiple flat directions, some of which carry a net baryon or lepton number. Condensates in such directions form during inflation and later fragment into Q-balls, which can become the building blocks of primordial black holes. [...]

<math display="inline"><mi>G</mi></math> objects and primordial black holes / Flores, Marcos M. (UCLA) ; Kusenko, Alexander (UCLA ; CERN ; Tokyo U., IPMU) ; Ghez, Andrea M. (UCLA) ; Naoz, Smadar (UCLA)
We suggest that "$G$ objects" recently discovered in the Galactic Center may be clouds of gas bound by the gravitational field of stellar-mass black holes produced in the interactions of sublunar primordial black holes with neutron stars. If dark matter is composed of primordial black holes with masses $(10^{-16} - 10^{-10}) M_\odot$, these black holes can be captured by neutron stars in the Galactic Center, where the dark matter density is high. [...]

Defrosting and Blast Freezing Dark Matter / Flores, Marcos M. (UCLA) ; Kouvaris, Chris (Natl. Tech. U., Athens) ; Kusenko, Alexander (UCLA ; Tokyo U., IPMU ; CERN)
We show that the present-day dark matter abundance can be produced through a novel mechanism that involves a very rapid thermal freeze-out caused by inhomogeneous heating and successive fast cooling of small fireballs in the early Universe. The fireballs can be produced from energy deposited in small scale structure growth induced by Yukawa interactions in certain particle species. [...]

Gravitational waves from rapid structure formation on microscopic scales before matter-radiation equality / Flores, Marcos M. (UCLA) ; Kusenko, Alexander (UCLA ; Tokyo U., IPMU ; CERN) ; Sasaki, Misao (Tokyo U., IPMU ; Kyoto U., Yukawa Inst., Kyoto ; Taiwan, Natl. Taiwan U.)
The existence of scalar fields can be probed by observations of stochastic gravitational waves. Scalar fields mediate attractive forces, usually stronger than gravity, on the length scales shorter than their Compton wavelengths, which can be non-negligible in the early Universe, when the horizon size is small. [...]

Fireball baryogenesis from early structure formation due to Yukawa forces / Flores, Marcos M. (UCLA) ; Kusenko, Alexander (UCLA ; Tokyo U., IPMU ; CERN) ; Pearce, Lauren (Penn State U.) ; White, Graham (Tokyo U., IPMU)
We show that viable electroweak baryogenesis can be realized without a first-order phase transition if plasma is heated inhomogeneously by nongravitational structure formation in some particle species. Yukawa interactions can mediate relatively long-range attractive forces in the early Universe. [...]
