We measure the zero-temperature equation of state of a homogeneous Bose gas of (7)Li atoms by analyzing the in situ density distributions of trapped samples. For increasing repulsive interactions our data show a clear departure from mean-field theory and provide a quantitative test of the many-body corrections first predicted in 1957 by Lee, Huang, and Yang [Phys. Rev. 106, 1135 (1957).]. We further probe the dynamic response of the Bose gas to a varying interaction strength and compare it to… Expand
Thermodynamics of a dilute Bose gas: a path-integral Monte-Carlo study
We present precise path-integral Monte-Carlo results of the thermodynamics of a homogeneous dilute Bose gas. Pressure and energy are calculated as a function of temperature both below and above theExpand
Critical properties of weakly interacting Bose gases as modified by a harmonic confinement
The critical properties of the phase transition from a normal gas to a BEC (superfluid) of a harmonically confined Bose gas are addressed with the knowledge of an equation of state of the underlyingExpand
Universal Loss Dynamics in a Unitary Bose Gas
The low temperature unitary Bose gas is a fundamental paradigm in few-body and many-body physics, attracting wide theoretical and experimental interest. Here we first present a theoretical model thatExpand
Collective oscillations of a trapped atomic gas in low dimensions and thermodynamics of one-dimensional Bose gas
Ultracold atoms are exceptional tools to explore the physics of quantum matter. In fact, the high degree of tunability of ultracold Bose and Fermi gases makes them ideal systems for quantumExpand
Universal prethermal dynamics of Bose gases quenched to unitarity
Degenerate and thermal Bose gases, quenched so that the interparticle interactions are as strong as allowed by quantum mechanics, exhibit dynamics that can be expressed in terms of universal functions. Expand
Thermodynamics of ultracold Bose and Fermi gases
The quantum many-body problem is at the heart of some of the most formidable open problems in modern physics, such as high-T$_c$ superconductivity or the behaviour of neutron stars. Ultracold atomicExpand
On the Ground-State Energy and Local Pressure of an Inhomogeneous Bose Gas
The exact expression for the average kinetic energy of an inhomogeneous Bose gas in the ground state is obtained as a functional of the inhomogeneous density of the Bose–Einstein condensate. TheExpand
On the ground state energy of the inhomogeneous Bose gas
Within the self-consistent Hartree–Fock approximation, an explicit in this approximation expression for the ground state energy of inhomogeneous Bose gas is derived as a functional of theExpand
Coherence and superfluidity of Bose gases in reduced dimensions: from harmonic traps to uniform fluids
The dimensionality of a system strongly affects its physical properties; the phase transitions that take place and the type of order that arises depend on the dimension. In low dimensional systemsExpand
Dimensional crossover for the beyond-mean-field correction in Bose gases
We present a detailed beyond-mean-field analysis of a weakly interacting Bose gas in the crossover from three to low dimensions. We find an analytical solution for the energy and provide a clearExpand
