Strongdeco: Expansion of analytical, strongly correlated quantum states into a many-body basis
B. Juliá-Díaz, T. Graß
We provide a Mathematica code for decomposing strongly correlated quantum states described by a first-quantized, analytical wave function into many-body Fock states. Within them, t…
Fractional quantum Hall states of few bosonic atoms in geometric gauge fields
B. Juliá-Díaz, T. Graß, N. Barberán +1
We employ the exact diagonalization method to analyze the possibility of generating strongly correlated states in two-dimensional clouds of ultracold bosonic atoms which are subjec…
Order by Disorder in Spin-Orbit Coupled Bose-Einstein Condensates
Ryan Barnett, Stephen Powell, Tobias Grass +2
Motivated by recent experiments, we investigate the system of isotropically-interacting bosons with Rashba spin-orbit coupling. At the non-interacting level, there is a macroscopic…
Quantum phase transition of ultracold bosons in the presence of a non-Abelian synthetic gauge field
T. Grass, K. Saha, K. Sengupta +1
We study the Mott phases and the superfluid-insulator transition of two-component ultracold bosons on a square optical lattice in the presence of a non-Abelian synthetic gauge fiel…
Robustness of Fractional Quantum Hall States with Dipolar Atoms in Artificial Gauge Fields
T. Grass, M. A. Baranov, M. Lewenstein
The robustness of fractional quantum Hall states is measured as the energy gap separating the Laughlin ground-state from excitations. Using thermodynamic approximations for the cor…
Strongly correlated states of a small cold atomic cloud from geometric gauge fields
B. Juliá-Díaz, D. Dagnino, K. J. Günter +4
Using exact diagonalization for a small system of cold bosonic atoms, we analyze the emergence of strongly correlated states in the presence of an artificial magnetic field. This g…
