Francesca Ferlaino (born 1977) is an Italian-Austrian experimental physicist known for her research on quantum matter. She is a professor of physics at the University of Innsbruck. [1] [2]
Francesca Ferlaino was born in Naples, Italy. She studied physics at the University of Naples Federico II (1995–2000) and was an undergraduate research fellow at the International School for Advanced Studies (SISSA) in Trieste (1999–2000). She did a PhD in physics at the University of Florence and the European Laboratory for Non-Linear Spectroscopy (LENS) (2001–2004). In 2007 she moved to the University of Innsbruck, Austria, where she was a research and teaching associate and started her own research group. In 2014 she became a professor of physics at the University of Innsbruck and research director at the Institute for Quantum Optics and Quantum Information (IQOQI) of the Austrian Academy of Sciences. [3]
Her research activity explores quantum phenomena in atomic gases at ultralow temperatures with contributions spanning topics including quantum matter of atoms and molecules and few-body and scattering physics. Over the last years, she focuses specifically on the strongly magnetic, and rather unexplored, Erbium and Dysprosium atomic species, realizing in 2012 world's first Bose-Einstein condensation of Erbium, [4] and in 2018 the first dipolar quantum mixture of Erbium and Dysprosium. [5] In 2019, she was able to prepare the first long-lived supersolid state, an elusive and paradoxical state where superfluid flow and crystal rigidity coexist. [6] With these systems, she has explored a variety of many-body quantum phenomena dictated by the long-range and anisotropic dipolar interaction among the atoms. In 2021 she created suprasolid states along two dimensions. [7]
Her work has earned her multiple awards, including the Grand Prix de Physique "Cécile-DeWitt Morette/École de Physique des Houches" from the French Academy of Sciences (2019), [8] the Junior BEC Award (2019), [9] the Feltrinelli Prize (2017) [10] and the Erwin Schrödinger Prize (2017), [11] the highest award of the Austrian Academy of Sciences. In addition, she is the recipient of an Alexander von Humboldt Professorship (2013), [12] a START-Prize (2009) and three ERC Grants (Starting 2010, Consolidator 2016 and Advanced 2022) [13] She was elected as a Fellow of the American Physical Society (APS) in 2019, after a nomination from the APS Division of Atomic, Molecular and Optical Physics, "for ground-breaking experiments on dipolar quantum gases of erbium atoms, including the attainment of quantum degeneracy of bosons and fermions, studies on quantum-chaotical scattering, the formation of quantum droplets, and investigations on the roton spectrum".

In condensed matter physics, a Bose–Einstein condensate (BEC) is a state of matter that is typically formed when a gas of bosons at very low densities is cooled to temperatures very close to absolute zero. Under such conditions, a large fraction of bosons occupy the lowest quantum state, at which point microscopic quantum mechanical phenomena, particularly wavefunction interference, become apparent macroscopically. A BEC is formed by cooling a gas of extremely low density to ultra-low temperatures.
Dysprosium is the chemical element with the symbol Dy and atomic number 66. It is a rare-earth element in the lanthanide series with a metallic silver luster. Dysprosium is never found in nature as a free element, though, like other lanthanides, it is found in various minerals, such as xenotime. Naturally occurring dysprosium is composed of seven isotopes, the most abundant of which is 164Dy.
In theoretical physics, a roton is an elementary excitation, or quasiparticle, seen in superfluid helium-4 and Bose–Einstein condensates with long-range dipolar interactions or spin-orbit coupling. The dispersion relation of elementary excitations in this superfluid shows a linear increase from the origin, but exhibits first a maximum and then a minimum in energy as the momentum increases. Excitations with momenta in the linear region are called phonons; those with momenta close to the minimum are called rotons. Excitations with momenta near the maximum are called maxons.
In condensed matter physics, a supersolid is a spatially ordered material with superfluid properties. In the case of helium-4, it has been conjectured since the 1960s that it might be possible to create a supersolid. Starting from 2017, a definitive proof for the existence of this state was provided by several experiments using atomic Bose–Einstein condensates. The general conditions required for supersolidity to emerge in a certain substance are a topic of ongoing research.
Deborah Shiu-lan Jin was an American physicist and fellow with the National Institute of Standards and Technology (NIST); Professor Adjunct, Department of Physics at the University of Colorado; and a fellow of the JILA, a NIST joint laboratory with the University of Colorado.
Wolfgang Ketterle is a German physicist and professor of physics at the Massachusetts Institute of Technology (MIT). His research has focused on experiments that trap and cool atoms to temperatures close to absolute zero, and he led one of the first groups to realize Bose–Einstein condensation in these systems in 1995. For this achievement, as well as early fundamental studies of condensates, he was awarded the Nobel Prize in Physics in 2001, together with Eric Allin Cornell and Carl Wieman.
Rudolf Grimm is an experimental physicist from Austria. His work centres on ultracold atoms and quantum gases. He was the first scientist worldwide who, with his team, succeeded in realizing a Bose–Einstein condensation of molecules.
A spin ice is a magnetic substance that does not have a single minimal-energy state. It has magnetic moments (i.e. "spin") as elementary degrees of freedom which are subject to frustrated interactions. By their nature, these interactions prevent the moments from exhibiting a periodic pattern in their orientation down to a temperature much below the energy scale set by the said interactions. Spin ices show low-temperature properties, residual entropy in particular, closely related to those of common crystalline water ice. The most prominent compounds with such properties are dysprosium titanate (Dy2Ti2O7) and holmium titanate (Ho2Ti2O7). The orientation of the magnetic moments in spin ice resembles the positional organization of hydrogen atoms (more accurately, ionized hydrogen, or protons) in conventional water ice (see figure 1).
Joannes Theodorus Maria (Jook) Walraven is a Dutch experimental physicist at the Van der Waals-Zeeman Institute for experimental physics in Amsterdam. From 1967 he studied physics at the University of Amsterdam. Both his doctoral research and PhD research was with Isaac Silvera, on the subject of Bose-Einstein Condensation. Because of the difficulty of his research subject, his promotion took six years instead of four. The aim of his PhD research was to make a gas of atomic hydrogen, which could become the world's first quantum gas. This might then be a suitable candidate for a Bose-Einstein Condensate (BEC).
