Beyond Random Phase Approximation in electron-hole bilayer superfluidity
Filippo Pascucci, Stefania De Palo, Sara Conti +3
We derive the normal and anomalous proper polarization functions and the screened Coulomb interactions in a two-dimensional superfluid electron-hole bilayer, including all first-or…
A Gross-Pitaevskii theory for an excitonic incompressible Bose solid
Sara Conti, Andrey Chaves, Alexander R. Hamilton +3
We show that interlayer excitons in double-layer semiconductor heterostructures can form a Bose solid, which is an incompressible supersolid characterized by exactly one boson per…
Effects of intra-layer correlations on electron-hole double-layer superfluidity
Filippo Pascucci, Sara Conti, Andrea Perali +2
We investigate the correlations acting within the layers in a superfluid system of electron-hole spatially separated layers. In this system of quasi-dipoles, the dominant correlati…
Flattening conduction and valence bands for interlayer excitons in a moiré MoS/WSe heterobilayer
Sara Conti, Andrey Chaves, Tribhuwan Pandey +4
We explore the flatness of conduction and valence bands of interlayer excitons in MoS/WSe van der Waals heterobilayers, tuned by interlayer twist angle, pressure, and exter…
Chester supersolid of spatially indirect excitons in double-layer semiconductor heterostructures
Sara Conti, Andrea Perali, Alexander R. Hamilton +3
A supersolid, a counter-intuitive quantum state in which a rigid lattice of particles flows without resistance, has to date not been unambiguously realised. Here we reveal a supers…
Josephson effect as signature of electron-hole superfluidity in bilayers of van der Waals heterostructures
Filippo Pascucci, Sara Conti, David Neilson +2
We investigate a Josephson junction in an electron-hole superfluid in a double layer TMD heterostructure. Observation of a critical tunneling current is a clear signature of superf…
Electron-hole superfluidity in strained Si/Ge type II heterojunctions
Sara Conti, Samira Saberi Pouya, Andrea Perali +5
Excitons are promising candidates for generating superfluidity and Bose-Einstein Condensation (BEC) in solid state devices, but an enabling material platform with in-built bandstru…
Three-dimensional electron-hole superfluidity in a superlattice close to room temperature
M. Van der Donck, S. Conti, A. Perali +4
Although there is strong theoretical and experimental evidence for electron-hole superfluidity in separated sheets of electrons and holes at low , extending superfluidity to hig…
A doping-dependent switch from one- to two-component superfluidity at temperature above 100K in coupled electron-hole Van der Waals heterostructures
Sara Conti, Matthias Van der Donck, Andrea Perali +2
The hunt for high temperature superfluidity has received new impetus from the discovery of atomically thin stable materials. Electron-hole superfluidity in coupled MoSe2-WSe2 monol…
Experimental conditions for observation of electron-hole superfluidity in GaAs heterostructures
Samira Saberi-Pouya, Sara Conti, Andrea Perali +4
The experimental parameter ranges needed to generate superfluidity in optical and drag experiments in GaAs double quantum wells are determined, using a formalism that includes self…
Multicomponent screening and superfluidity in gapped electron-hole double bilayer graphene with realistic bands
Sara Conti, Andrea Perali, Francois M. Peeters +1
Superfluidity has recently been reported in double electron-hole bilayer graphene. The multiband nature of the bilayers is important because of the very small band gaps between con…
Multicomponent electron-hole superfluidity and the BCS-BEC crossover in double bilayer graphene
S. Conti, A. Perali, F. M. Peeters +1
Superfluidity in coupled electron-hole sheets of bilayer graphene is predicted here to be multicomponent because of the conduction and valence bands. We investigate the superfluid…
