Journal ArticleDOI
Correlated electron–hole plasma in organometal perovskites
Michele Saba,Michele Cadelano,Daniela Marongiu,Feipeng Chen,Valerio Sarritzu,Nicola Sestu,Cristiana Figus,Mauro Aresti,Roberto Piras,Alessandra Geddo Lehmann,Carla Cannas,Anna Maria Giovanna Musinu,Francesco Quochi,Antonio Andrea Mura,Giovanni Bongiovanni +14 more
TL;DR: Photoluminescence and transmission spectroscopy is used to show that photoexcitations give rise to a conducting plasma of unbound but Coulomb-correlated electron-hole pairs at all excitations of interest for light-energy conversion and stimulated optical amplification in organic-inorganic perovskites.
Journal ArticleDOI
Atom Interferometry with Bose-Einstein Condensates in a Double-Well Potential
Yong-il Shin,Michele Saba,T.A. Pasquini,Wolfgang Ketterle,David E. Pritchard,A. E. Leanhardt +5 more
TL;DR: A trapped-atom interferometer was demonstrated using gaseous Bose-Einstein condensates coherently split by deforming an optical single- well potential into a double-well potential.
Journal ArticleDOI
High-temperature ultrafast polariton parametric amplification in semiconductor microcavities.
Michele Saba,Cristiano Ciuti,Jacqueline Bloch,V. Thierry-Mieg,Régis André,Le Si Dang,S. Kundermann,A. Mura,Giovanni Bongiovanni,Jl Staehli,Benoit Deveaud +10 more
TL;DR: 105 polaritons occupy the same quantum state during the amplification, realizing a dynamical condensate of strongly interacting bosons which can be studied at high temperature and could be exploited for high-repetition all-optical microscopic switches and amplifiers.
Journal ArticleDOI
Long phase coherence time and number squeezing of two Bose-Einstein condensates on an atom chip.
Gyu-Boong Jo,Yong-il Shin,Sebastian Will,T.A. Pasquini,Michele Saba,Wolfgang Ketterle,David E. Pritchard,M. Vengalattore,Mara Prentiss +8 more
TL;DR: A rotationally sensitive (Sagnac) geometry for a guided atom interferometer by propagating the split condensates is demonstrated and enhanced coherence time is attributed to number squeezing of the initial state.
Journal ArticleDOI
Cooling Bose-Einstein Condensates Below 500 Picokelvin
A. E. Leanhardt,T.A. Pasquini,Michele Saba,Andre Schirotzek,Yong-il Shin,David Kielpinski,David E. Pritchard,Wolfgang Ketterle +7 more
TL;DR: Spin-polarized gaseous Bose-Einstein condensates were confined by a combination of gravitational and magnetic forces and evaporatively reduced in size to 2500 atoms, cooling the entire cloud in all three dimensions to a kinetic temperature of 450 ± 80 picokelvin.
