Dimension of the singular set in the parabolic obstacle problem
Alejandro MartÃnez, Xavier Ros-Oton
In this paper we study the singular set in the parabolic obstacle problem for general obstacles . We prove that the singular set has parabolic Hausdorff dimension at…
Hybrid Dielectric-Graphene SERS Metasurfaces for Antibody Sensing
Javier Redolat, Miguel Sinusia Lozano, MarÃa Camarena Pérez +8
We present a hybrid surface-enhanced Raman spectroscopy (SERS) platform based on dielectric silicon metasurfaces integrated with functionalized graphene for the selective detection…
Dual-mode phonon dynamics and lasing in optomechanical cavities
Raúl Ortiz, Carlos Mas ArabÃ, Carles Milián +1
We use the full nonlinear bifurcation theory as a powerful methodology to thoroughly classify and predict the phonon lasing dynamics in optomechanical cavities. We exemplify its sc…
Chiral optical forces in a slot waveguide for separation of molecules in gas
Josep MartÃnez-Romeu, Daniel Arenas-Ortega, Iago Diez +1
Chiral optical forces present an exciting avenue into the separation of enantiomers in an all-optical fashion. In this work, we explore via numerical simulations and analytical cal…
Self-modulated multimode silicon cavity optomechanics
David Alonso-Tomás, Carlos Mas ArabÃ, Carles Milián +3
Multimode cavity optomechanics, where multiple mechanical degrees of freedom couple to optical cavity modes, provides a rich platform for exploring nonlinear dynamics and engineeri…
