We investigate the superfluid-to-normal zero temperature quantum phase transitions of asymmetric two-component Fermi gases as a function of the chemical potential imbalance $h$. The calculations are performed for homogeneous and trapped imbalanced systems. We concentrate at unitarity, characterized by a divergent interaction parameter $k_F a$, where most of the current experiments are realized. For homogeneous systems, we determine the critical chemical potential imbalance $h_c$ at which…

The Gor'kov and Melik‐Barkhudarov Correction to an Imbalanced Fermi Gas in the Presence of Impurities
The effects of induced interactions are calculated in both clean and dirty situations, for balanced and imbalanced Fermi gases. The effects of nonmagnetic impurities on the induced interactions


Superfluidity in Two-Dimensional Imbalanced Fermi Gases
We study the zero temperature ground state of a two-dimensional atomic Fermi gas with chemical potential and population imbalance in the mean-field approximation. All calculations are performed in
Fermionic Superfluidity with Imbalanced Spin Populations
The superfluidity regime was established in a two-state mixture of ultracold fermionic atoms with imbalanced state populations and the quantum phase transition to the normal state was characterized, known as the Pauli limit of superfluidity.
Imbalanced Feshbach-resonant Fermi gases
We present an overview of recent developments in species-imbalanced ('polarized') Feshbach-resonant Fermi gases. We summarize the current status of thermodynamics of these systems in terms of a phase
Cold asymmetrical fermion superfluids
In this work we investigate the general properties and the ground state of an asymmetrical dilute gas of cold fermionic atoms, formed by two particle species having different densities. We have shown
Phase structure of spin-imbalanced unitary Fermi gases
We investigate the phase structure of spin-imbalanced unitary Fermi gases beyond mean-field theory by means of the Functional Renormalization Group. In this approach, quantum and thermal fluctuations
Observation of phase separation in a strongly interacting imbalanced fermi gas.
The in situ distribution of the density difference between two trapped spin components is obtained using phase-contrast imaging and 3D image reconstruction and the phase transition induces a dramatic change in the density profiles as excess fermions are expelled from the superfluid.
Universal Phase Diagram and Scaling Functions of Imbalanced Fermi Gases
We discuss the phase diagram and the universal scaling functions of attractive Fermi gases at finite imbalance. The existence of a quantum multicritical point for the unitary gas at vanishing
Phase Separation and Pair Condensation in a Spin-Imbalanced 2D Fermi Gas.
The observation of zero momentum pair condensates in 2D spin-imbalanced gases opens the way to explorations of more exotic superfluid phases that occupy a large part of the phase diagram in lower dimensions.
Pairing and Phase Separation in a Polarized Fermi Gas
We report the observation of pairing in a gas of atomic fermions with unequal numbers of two components. Beyond a critical polarization, the gas separates into a phase that is consistent with a
Normal phase of an imbalanced Fermi gas.
In this Letter, a simple theory is devised to describe dilute Fermi-polaron ensembles corresponding to the normal phase of an imbalanced Fermani gas, and an exact formula is obtained for the dominant interaction between polarons.
