Dual density waves with neutral and charged dipolar excitons of GaAs bilayers
Camille Lagoin, Stephan Suffit, Kirk Baldwin +2
Strongly correlated quantum particles in lattice potentials are the building blocks for a large variety of quantum insulators, for instance Mott phases and density waves breaking t…
Key role of the moire potential for the quasi-condensation of interlayer excitons in van der Waals heterostructures
Camille Lagoin, Francois Dubin
Interlayer excitons confined in bilayer heterostructures of transition metal dichalcogenides (TMDs) offer a promising route to implement two-dimensional dipolar superfluids. Here,…
Quasi-condensation of bilayer excitons in a periodic potential
Camille Lagoin, Stephan Suffit, Kenneth West +4
We study two-dimensional excitons confined in a lattice potential, for high fillings of the lattice sites. We show that a quasi-condensate is possibly formed for small values of th…
A Microscopic Lattice for Two-dimensional Dipolar Excitons
Camille Lagoin, Stephan Suffit, Mathieu Bernard +5
We report a two-dimensional artificial lattice for dipolar excitons confined in a GaAs double quantum well. Exploring the regime of large fillings per lattice site, we verify that…
High spectral resolution of GaAs/AlAs phononic cavities by subharmonic resonant pump-probe excitation
Camille Lagoin, Bernard Perrin, Paola Atkinson +1
We present here precise measurement of the resonance frequency, lifetime and shape of confined acoustic modes in the tens of GHz regime in GaAs/AlAs superlattice planar and micropi…
