NJP: Correlations of ultracold dipolar bosons in optical lattices

Correlations of strongly interacting ultracold dipolar bosons in optical lattices

We explore and analyze the rich structure of correlations of ultracold bosons with dipolar interactions in optical lattices and demonstrate that their quantum phases may be inferred from them.

NJP: Managing the Correlations of Ultracold Bosons in Triple Wells

Management of the correlations of Ultracold Bosons in triple wells

We investigated the correlations of ultracold many-boson systems in tilted triple wells with contact and dipolar interactions.

We were able to put forward a protocol to manage the correlation functions of the many-body state by tuning the depth and tilt of the lattice and the strength of the interactions between the particles.

PRX: Granulation and Faraday waves in driven quantum systems

Parametric excitation of a Bose-Einstein condensate: From Faraday waves to granulation

Surprisingly, the quantum version of granulation and Faraday waves can be produced in the same quantum system: a gas of trapped atoms cooled very close to absolute zero temperature.

NJP: Fragmented superradiance and polarization in two-component Bose-Einstein condensates in a cavity

Many-body physics in two-component Bose–Einstein condensates in a cavity: fragmented superradiance and polarization

Rich many-body physics arise in interacting laser-pumped ultracold two-component bosons in a cavity.

PRA: Superlattice switching in a driven-dissipative Bose-Einstein condensate in a cavity

We have explored a resonance between a Bose-Einstein condensate in a cavity and photons by modulating the pump laser power.

PRA: Entropies and correlations of ultracold bosons in a lattice

The collective behavior of interacting bosons in lattices comes in many different flavors.

PRA: Crystallization of dipolar bosons and its detection in single-shot images

Dipolar ultracold bosonic quantum gases feature a remarkable crystal state for strong dipolar interactions.

JLTP: Resonances and Fragmentation through Stirring

Resonances and Dynamical Fragmentation in a Stirred Bose-Einstein Condensate

Superfluids are distinguished from ordinary fluids by the quantized manner in which the rotation is manifested in them.

PRA: From vortices to solitonic vortices

Transition from vortices to solitonic vortices in trapped atomic Bose-Einstein condensates

Motivated by recent experiments, we study theoretically the dynamics of vortices in the crossover from two dimensions to one

PRA: MCTDH-X for Hubbard Hamiltonians

Dynamics of Hubbard Hamiltonians with the multiconfigurational time-dependent Hartree method for indistinguishable particles

We apply the multiconfigurational time-dependent Hartree method for indistinguishable particles (MCTDH-X) to systems of bosons or fermions in lattices described by Hubbard-type Hamiltonians
