Shock waves in strongly interacting Fermi gas from time-dependent density functional calculations

  author={Francesco Ancilotto and Luca Salasnich and F. Toigo},
  journal={Physical Review A},
Motivated by a recent experiment [Phys. Rev. Lett. 106, 150401 (2011)] we simulate the collision between two clouds of cold Fermi gas at unitarity conditions by using an extended Thomas-Fermi density functional. At variance with the current interpretation of the experiments, where the role of viscosity is emphasized, we find that a quantitative agreement with the experimental observation of the dynamics of the cloud collisions is obtained within our superfluid effective hydrodynamics approach…

Shock waves in colliding Fermi gases at finite temperature

We study the formation and the dynamics of a shock wave originating from the collision between two ultracold clouds of strongly interacting fermions as observed at a lower temperature in an

Dispersive Effects in the Unitary Fermi Gas

We investigate within density functional theory various physical properties of the zero-temperature unitary Fermi gas which critically depend on the presence of a dispersive gradient term in the

Finite-temperature dynamics of shock waves in an ultracold Fermi gas

The study of finite-temperature dynamics of one-dimensional Fermi gases is a challenging problem. These systems can present different phenomena, including the formation and propagation of shock waves

Dynamics of shock waves in a superfluid unitary Fermi gas

We study the formation and dynamics of shock waves initiated by a repulsive potential in a superfluid unitary Fermi gas by using the order-parameter equation. In the theoretical framework, the

Time-Dependent Density Functional Theory and the Real-Time Dynamics of Fermi Superfluids

I describe the time-dependent superfluid local density approximation, which is an adiabatic extension of the density functional theory to superfluid Fermi systems and their real-time dynamics. This

Anisotropic expansions of a strongly interacting Fermi superfluid containing a vortex

We present a study of static and expansion properties of strongly interacting Fermi superfluids containing a vortex initially trapped by cylindrically symmetric potentials. Based on the

Shock waves in quasi one-dimensional Bose-Einstein condensate

Abstract.We study analytically and numerically the generation of shock waves in a quasi-one-dimensional Bose-Einstein condensate (BEC) made of dilute and ultracold alkali-metal atoms. For the BEC we

Fermionic shock waves: Distinguishing dissipative versus dispersive regularizations

The collision of two clouds of Fermi gas at unitarity (UFG) has been recently observed to lead to shock waves whose regularization mechanism, dissipative or dispersive, is being debated. While

Shock Waves in a Superfluid with Higher-Order Dispersion

Higher-order dispersion can lead to intriguing dynamics that are becoming a focus of modern hydrodynamics research. Such systems occur naturally, for example in shallow water waves and nonlinear

Universal shock-wave propagation in one-dimensional Bose fluids

We propose a protocol for creating moving, long-lived shock waves in interacting one-dimensional Bose fluids. The fluid is prepared in a moving state by phase imprinting and sent against the walls of
