Supersolid crystals of dipolar excitons in a lattice
C. Morin, C. Lagoin, T. Gupta +5
In condensed-matter physics, long-range correlations introduce quantum states of matter that challenge intuition. For example, supersolids combine density order that manifests as s…
Probing moire excitons in MoSe2/WSe2 heterobilayers by combined micro-photoluminescence and lateral force microscopy
L. Caussou, H. Moutaabbid, M. Bernard +6
We study interlayer excitons in MoSe2/WSe2 heterobilayers, by combining lateral force microscopy and micro-photoluminescence spectroscopy. This allows us to correlate the spatial p…
Bose-Hubbard simulator with long-range hopping
Camille Lagoin, Corentin Morin, Kirk Baldwin +2
Enriching condensed-matter systems with quantum optical phenomena currently drives intense research efforts, particularly to introduce collective quantum correlations. Here we acce…
Superlattice quantum solid of dipolar excitons
Camille Lagoin, Kirk Baldwin, Loren Pfeiffer +1
We study dipolar excitons confined at 330 mK in a square electrostatic lattice of a GaAs double quantum well. In the dipolar occupation blockade regime, at 3/2 filling, we evidence…
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…
Extended Bose-Hubbard model with dipolar excitons
C. Lagoin, U. Bhattacharya, T. Grass +7
The Hubbard model constitutes one of the most celebrated theoretical frameworks of condensed-matter physics. It describes strongly correlated phases of interacting quantum particle…
Mott insulator of strongly interacting two-dimensional excitons
Camille Lagoin, Stephan Suffit, Kirk Baldwin +2
In condensed-matter physics, electronic Mott insulators have triggered considerable research due to their intricate relation with high-temperature superconductors. However, unlike…
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…
Switching off energy decay channels in nanomechanical resonators
J. Guettinger, A. Noury, P. Weber +7
Energy decay plays a central role in a wide range of phenomena, such as optical emission, nuclear fission, and dissipation in quantum systems. Energy decay is usually described as…
Acoustic confinement in superlattice cavities
Daniel Garcia-Sanchez, Samuel Déleglise, Jean-Louis Thomas +3
The large coupling rate between the acoustic and optical fields confined in GaAs/AlAs superlattice cavities makes them appealing systems for cavity optomechanics. We have developed…
