Primordial black holes from spectator field bubbles
David Navidad Maeso, Luca Marzola, Martti Raidal +2
We study the evolution of light spectator fields in an asymmetric polynomial potential. During inflation, stochastic fluctuations displace the spectator field from the global minim…
The dynamics of natural selection in dispersal-structured populations
E. Heinsalu, D. Navidad Maeso, M. Patriarca
The problem of natural selection in dispersal-structured populations consisting of individuals characterized by different diffusion coefficients is studied. The competition between…
Fast Yet Quantum-Efficient Few-Layer Vertical MoS2 Photodetectors
David Maeso, Andres Castellanos-Gomez, Nicolas Agraït +1
Semiconducting 2D materials, such as molybdenum disulfide (MoS2) and other members of the transition metal dichalcogenide family, have emerged as promising materials for applicatio…
Strong Modulation of Optical Properties in Rippled 2D GaSe via Strain Engineering
David Maeso, Sahar Pakdel, Hernan Santos +4
Few-layer GaSe is one of the latest additions to the family of 2D semiconducting crystals whose properties under strain are still relatively unexplored. Here, we study rippled nano…
Optical contrast and refractive index of natural van der Waals heterostructure nanosheets of franckeite
Patricia Gant, Foad Ghasemi, David Maeso +7
We study mechanically exfoliated nanosheets of franckeite by quantitative optical microscopy. The analysis of transmission mode and epi-illumination mode optical microscopy images…
