Fermi–Bose mixture in mixed dimensions
New Journal of Physics, 2017 One of the challenging goals in the studies of many-body physics with ultracold atoms is the creation of a topological ${p}_{x}+{{\rm{i}}{p}}_{y}$ superfluid for identical fermions in two dimensions (2D).

Laser assisted tunneling in a Tonks–Girardeau gas
New Journal of Physics, 2016 We investigate the applicability of laser assisted tunneling in a strongly interacting one-dimensional (1D) Bose gas (the Tonks–Girardeau gas) in optical lattices.

Dark Energy Survey Year 3 results: Cosmological constraints from galaxy clustering and weak lensing [PDF]
Physical Review D, 2021 We present the first cosmology results from large-scale structure in the Dark Energy Survey (DES) spanning 5000 deg$^2$. We perform an analysis combining three two-point correlation functions (3$\times$2pt): (i) cosmic shear using 100 million source ...

Fluorescence detection at the atom shot noise limit for atom interferometry
New Journal of Physics, 2014 Atom interferometers (AIs) are promising tools for precision measurement with applications ranging from geophysical exploration and tests of the equivalence principle of general relativity to the detection of gravitational waves.

Magnetically Controlled Exchange Process in an Ultracold Atom-Dimer Mixture [PDF]
, 2009 We report on the observation of an elementary exchange process in an optically trapped ultracold sample of atoms and Feshbach molecules. We can magnetically control the energetic nature of the process and tune it from endoergic to exoergic, enabling the ...

Interpreting DESI 2024 BAO: Late-time dynamical dark energy or a local effect? [PDF]
Physical Review DWe perform fits to DESI, CMB and supernova data to understand the physical origin of the DESI hint for dynamical dark energy. We find that the linear parametrization of the equation of state $w$ may guide to misleading interpretations, such as the hint ...

Variational study of phase diagrams of spin–orbit coupled bosons
New Journal of Physics, 2016 We use a variational order method to explore the ground state phase diagrams of spin–orbit coupled Bose atoms in optical lattices. By properly parameterizing the order with an ansatz function for each possible phase and comparing their energies which are

Scattering lengths of calcium and barium isotopes [PDF]
, 2011 We have calculated the s-wave scattering length of all the even isotopes of calcium (Ca) and barium (Ba), in order to investigate the prospect of Bose-Einstein condensation (BEC).

Quantum enhancement of spin drag in a Bose gas
New Journal of Physics, 2015 In spintronics the active control and manipulation of spin currents is studied in solid-state systems. Opposed to charge currents, spin currents are strongly damped due to collisions between different spin carriers in addition to relaxation due to ...

Coherent light scattering from a two-dimensional Mott insulator [PDF]
, 2011 We experimentally demonstrate coherent light scattering from an atomic Mott insulator in a two-dimensional lattice. The far-field diffraction pattern of small clouds of a few hundred atoms was imaged while simultaneously laser cooling the atoms with the ...
