Observation of fragmentation of a spinor Bose-Einstein condensate [PDF]
Science, 2020 Description Fragmenting the condensate In a Bose-Einstein condensate, a sizable fraction of particles occupies a single quantum state. In some systems, it is in principle possible to have more than one such macroscopically occupied state.

Bipolarons in a Bose-Einstein Condensate. [PDF]
Physical Review Letters, 2018 Mobile impurities in a Bose-Einstein condensate form quasiparticles called polarons. Here, we show that two such polarons can bind to form a bound bipolaron state.

Quantum Depletion of a Homogeneous Bose-Einstein Condensate. [PDF]
Physical Review Letters, 2017 We measure the quantum depletion of an interacting homogeneous Bose-Einstein condensate and confirm the 70-year-old theory of Bogoliubov. The observed condensate depletion is reversibly tunable by changing the strength of the interparticle interactions ...

Parametric Excitation of a Bose-Einstein Condensate: From Faraday Waves to Granulation [PDF]
Physical Review X, 2017 A shaken Bose-Einstein condensate generates not only repeatable wave patterns known as Faraday waves, but also unexpected grains that may arise from shaking-induced quantum correlations.

New Journal of Physics, 2012 We theoretically study the loading of a two-species Bose-Einstein condensate to an optical lattice in a tightly-confined one-dimensional trap. Due to quantum fluctuations the relative inter and intra species phase coherence between the atoms and the on-site atom number fluctuations are reduced in the miscible regime.

Journal of Bangladesh Academy of Sciences, 1970 The work represents and investigates the stationary solutions of the one-dimensional Non-linear Schrödinger Equation (NLSE), for attractive non-linearity, in the Bose-Einstein condensates (BEC) under the box boundary condition and calculates the characteristics of internal modes of bright solitons (eigen modes of small perturbation of the condensate ...

Thin accretion disks around cold Bose-Einstein Condensate stars [PDF]
, 2015 Due to their superfluid properties some compact astrophysical objects, like neutron or quark stars, may contain a significant part of their matter in the form of a Bose-Einstein Condensate.

Universality of an impurity in a Bose-Einstein condensate [PDF]
, 2017 Universality is a powerful concept in physics, allowing one to construct physical descriptions of systems that are independent of the precise microscopic details or energy scales.

Characterisation of the dynamical quantum state of a zero temperature Bose-Einstein condensate [PDF]
, 2002 We describe the quantum state of a Bose-Einstein condensate at zero temperature. By evaluating the Q-function we show that the ground state of Bose-Einstein condensate under the Hartree approximation is squeezed.

Strong-coupling Bose polarons in a Bose-Einstein condensate [PDF]
, 2017 We use a non-perturbative renormalization group approach to develop a unified picture of the Bose polaron problem, where a mobile impurity is strongly interacting with a surrounding Bose-Einstein condensate (BEC).
