Three-body interacting bosons in free space.
We propose a method of controlling two- and three-body interactions in an ultracold Bose gas in any dimension. The method requires us to have two coupled internal single-particle states split in energy such that the upper state is occupied virtually but amply during collisions. By varying system parameters, one can switch off the two-body interaction while maintaining a strong three-body one. T...

1 + cos2 φ). The boundary conditions for the wavefunction on the borders of the domain can be derived from Eqs. (S2-S3). The set of four equations (S4-S5) is solved numerically by using the adiabatic hyperspherical approach. Namely, we first diagonalize the hyperspherical part, i.e., we fix Π and in the kinetic energy operator (S6) we keep only the second line. We choose a grid which has many p...
متن کاملPair superfluidity of three-body constrained bosons in two dimensions.
We examine the equilibrium properties of lattice bosons with attractive on-site interactions in the presence of a three-body hard-core constraint that stabilizes the system against collapse and gives rise to a dimer superfluid phase. Employing quantum Monte Carlo simulations, the ground state phase diagram of this system on the square lattice is analyzed. In particular, we study the quantum pha...
متن کاملUniversal relations for identical bosons from three-body physics.
Systems consisting of identical bosons with a large scattering length satisfy universal relations determined by 2-body physics that are similar to those for fermions with two spin states. They require the momentum distribution to have a large-momentum 1/k(4) tail and the radio-frequency transition rate to have a high-frequency 1/ω(3/2) tail, both of which are proportional to the 2-body contact....
متن کاملStrongly interacting bosons on a three-leg ladder in the presence of a homogeneous flux
Weperform a density-matrix renormalization-group study of strongly interacting bosons on a threeleg ladder in the presence of a homogeneous flux. Focusing on one-third filling, we explore the phase diagram in dependence of themagneticflux and the inter-leg tunneling strength.We find several phases including aMeissner phase, vortex liquids, a vortex lattice, as well as a staggered-current (SC) p...
