Multicomponent spin mixtures of two-electron fermions
Leonardo Fallani
These lecture notes contain an introduction to the physics of quantum mixtures of ultracold atoms trapped in multiple internal states. I will discuss the case of fermionic isotopes…
Enhancement of chiral edge currents in (+1)-dimensional atomic Mott-band hybrid insulators
Matteo Ferraretto, Andrea Richaud, Lorenzo Del Re +2
We consider the effect of a local interatomic repulsion on synthetic heterostructures where a discrete synthetic dimension is created by Raman processes on top of -symmetric…
Observation of Universal Hall Response in Strongly Interacting Fermions
T. -W. Zhou, G. Cappellini, D. Tusi +9
The Hall effect, which originates from the motion of charged particles in magnetic fields, has deep consequences for the description of materials, extending far beyond condensed ma…
Flavour-selective localization in interacting lattice fermions via SU(N) symmetry breaking
Daniele Tusi, Lorenzo Franchi, Lorenzo Francesco Livi +10
A large repulsion between particles in a quantum system can lead to their localization, as it happens for the electrons in Mott insulating materials. This paradigm has recently bra…
Engineering entanglement Hamiltonians with strongly interacting cold atoms in optical traps
R. E. Barfknecht, T. Mendes-Santos, L. Fallani
We present a proposal for the realization of entanglement Hamiltonians in one-dimensional critical spin systems with strongly interacting cold atoms. Our approach is based on the n…
Coherent Manipulation of Orbital Feshbach Molecules of Two-Electron Atoms
G. Cappellini, L. F. Livi, L. Franchi +5
Ultracold molecules have experienced increasing attention in recent years. Compared to ultracold atoms, they possess several unique properties that make them perfect candidates for…
State-dependent interactions in ultracold Yb probed by optical clock spectroscopy
L. Franchi, L. F. Livi, G. Cappellini +4
We report on the measurement of the scattering properties of ultracold Yb bosons in a three-dimensional (3D) optical lattice. Site occupancy in an atomic Mott insulator is…
Synthetic dimensions and spin-orbit coupling with an optical clock transition
L. F. Livi, G. Cappellini, M. Diem +8
We demonstrate a novel way of synthesizing spin-orbit interactions in ultracold quantum gases, based on a single-photon optical clock transition coupling two long-lived electronic…
Observation of chiral edge states with neutral fermions in synthetic Hall ribbons
M. Mancini, G. Pagano, G. Cappellini +8
Chiral edge states are a hallmark of quantum Hall physics. In electronic systems, they appear as a macroscopic consequence of the cyclotron orbits induced by a magnetic field, whic…
A one-dimensional liquid of fermions with tunable spin
Guido Pagano, Marco Mancini, Giacomo Cappellini +8
Correlations in systems with spin degree of freedom are at the heart of fundamental phenomena, ranging from magnetism to superconductivity. The effects of correlations depend stron…
Quasiparticle dynamics in a Bose insulator probed by inter-band Bragg spectroscopy
Nicole Fabbri, Sebastian D. Huber, David Clément +4
We investigate experimentally and theoretically the dynamical properties of a Mott insulator in decoupled one-dimensional chains. Using a theoretical analysis of the Bragg excitati…
Momentum-resolved study of an array of 1D strongly phase-fluctuating Bose gases
Nicole Fabbri, David Clément, Leonardo Fallani +2
We investigate the coherence properties of an array of one-dimensional Bose gases with short-scale phase fluctuations. The momentum distribution is measured using Bragg spectroscop…
Multi-band spectroscopy of inhomogeneous Mott-insulator states of ultracold bosons
D. Clement, N. Fabbri, L. Fallani +2
In this work, we use inelastic scattering of light to study the response of inhomogeneous Mott-insulator gases to external excitations. The experimental setup and procedure to prob…
