Patterning active materials with addressable soft interfaces

Pau Guillamat, Jordi Ignés-Mullol, Francesc Sagués

Motor-proteins are responsible for transport inside cells. Harnessing their activity is key towards developing new nano-technologies, or functional biomaterials. Cytoskeleton-like…

Multidimensional Josephson vortices in spin-orbit coupled Bose-Einstein condensates: snake instability and decay through vortex dipoles

A. Gallemí, M. Guilleumas, R. Mayol +1

We analyze the dynamics of Josephson vortex states in two-component Bose-Einstein condensates with Rashba-Dresselhaus spin-orbit coupling by using the Gross-Pitaevskii equation. In…

Coherent Quantum Phase Slip in two-component bosonic Atomtronic Circuits

A. Gallemí, A. Muñoz Mateo, R. Mayol +1

Coherent Quantum Phase Slip consists in the coherent transfer of vortices in superfluids. We investigate this phenomenon in two miscible coherently coupled components of a spinor B…

Quantification of dipolar interactions in FeO nanoparticles

Carlos Moya, Òscar Iglesias, Xavier Batlle +1

A general method for the quantification of dipolar interactions in assemblies of nanoparticles has been developed from a model sample constituted by magnetite nanoparticles of 5 nm…

Fast and rewritable colloidal assembly via field synchronized particle swapping

Pietro Tierno, Tom H. Johansen, Thomas M. Fischer

We report a technique to realize reconfigurable colloidal crystals by using the controlled motion of particle defects above an externally modulated magnetic substrate. The transpor…

Excluded volume causes integer and fractional plateaus in colloidal ratchet currents

Pietro Tierno, Thomas M. Fischer

We study the collective transport of paramagnetic colloids driven above a magnetic bubble lattice by an external rotating magnetic field. We measure a direct ratchet current which…

Persistent currents with non-quantized angular momentum

A. Muñoz Mateo, A. Gallemí, M. Guilleumas +1

We analyze the generation of persistent currents in Bose-Einstein condensates of ultracold gases confined in a ring. This phenomenon has been recently investigated in an experiment…

Fragmented condensation in Bose-Hubbard trimers with tunable tunnelling

A. Gallemí, M. Guilleumas, J. Martorell +3

We consider a Bose-Hubbard trimer, i.e. an ultracold Bose gas populating three quantum states. The latter can be either different sites of a triple-well potential or three internal…
