A model for nuclear spin product-state distributions of ultracold chemical reactions in magnetic fields
Goulven Quéméner, Ming-Guang Hu, Yu Liu +3
Based on a theoretical model where the nuclear spins remain unchanged during a collision, we provide an analytical and general expression for the nuclear spin state-to-state distri…
Detection of Long-Lived Complexes in Ultracold Atom-Molecule Collisions
Matthew A. Nichols, Yi-Xiang Liu, Lingbang Zhu +3
We investigate collisional loss in an ultracold mixture of KRb molecules and Rb atoms, where chemical reactions between the two species are energetically forbi…
Precision test of statistical dynamics with state-to-state ultracold chemistry
Yu Liu, Ming-Guang Hu, Matthew A. Nichols +4
Chemical reactions represent a class of quantum problems that challenge both the current theoretical understanding and computational capabilities. Reactions that occur at ultralow…
State-to-state control of ultracold molecular reactions
Ming-Guang Hu, Yu Liu, Matthew A. Nichols +4
Quantum control of reactive systems has enabled microscopic probes of underlying interaction potentials, the opening of novel reaction pathways, and the alteration of reaction rate…
Steering ultracold reactions through long-lived transient intermediates
Yu Liu, Ming-Guang Hu, Matthew A. Nichols +4
Controlling the pathways and outcomes of reactions is a broadly pursued goal in chemistry. In gas phase reactions, this is typically achieved by manipulating the properties of the…
Observation of Spatial Charge and Spin Correlations in the 2D Fermi-Hubbard Model
Lawrence W. Cheuk, Matthew A. Nichols, Katherine R. Lawrence +7
Strong electron correlations lie at the origin of transformative phenomena such as colossal magneto-resistance and high-temperature superconductivity. Already near room temperature…
Observation of 2D fermionic Mott insulators of K with single-site resolution
Lawrence W. Cheuk, Matthew A. Nichols, Katherine R. Lawrence +3
We report on the site-resolved observation of characteristic states of the two-dimensional repulsive Fermi-Hubbard model, using ultracold K atoms in an optical lattice. By v…
Computational issues in chemo-dynamical modelling of the formation and evolution of galaxies
Yves Revaz, Alexis Arnaudon, Matthew Nichols +2
Chemo-dynamical N-body simulations are an essential tool for understanding the formation and evolution of galaxies. As the number of observationally determined stellar abundances c…
A Quantum Gas Microscope for Fermionic Atoms
Lawrence W. Cheuk, Matthew A. Nichols, Melih Okan +5
Strongly interacting fermions define the properties of complex matter at all densities, from atomic nuclei to modern solid state materials and neutron stars. Ultracold atomic Fermi…
The post-infall evolution of a satellite galaxy
Matthew Nichols, Yves Revaz, Pascale Jablonka
As galaxy simulations increase in resolution more attention is being paid towards the evolution of dwarf galaxies and how the simulations compare to observations. Despite this incr…
The Smith Cloud and its dark matter halo: Survival of a Galactic disc passage
Matthew Nichols, Nestor Mirabal, Oscar Agertz +2
The current velocity of the Smith Cloud indicates that it has undergone at least one passage of the Galactic disc. Using hydrodynamic simulations we examine the present day structu…
The effect of gravitational tides on dwarf spheroidal galaxies
Matthew Nichols, Yves Revaz, Pascale Jablonka
The effect of the local environment on the evolution of dwarf spheroidal galaxies is poorly understood. We have undertaken a suite of simulations to investigate the tidal impact of…
The Epoch of Assembly of Two Galaxy Groups: A comparative study
Matthew Nichols, Joss Bland-Hawthorn
Nearby galaxy groups of comparable mass to the Local Group show global variations that reflect differences in their evolutionary history. Satellite galaxies in groups have higher l…
Accretion of the Magellanic system onto the Galaxy
Matthew Nichols, James Colless, Matthew Colless +1
Our Galaxy is surrounded by a large family of dwarf galaxies of which the most massive are the Large and Small Magellanic Clouds (LMC and SMC). Recent evidence suggests that system…
Episodic starbursts in dwarf spheroidal galaxies: a simple model
Matthew Nichols, Doug Lin, Joss Bland-Hawthorn
Dwarf galaxies in the Local Group appear to be stripped of their gas within 270 kpc of the host galaxy. Color-magnitude diagrams of these dwarfs, however, show clear evidence of ep…
Gas depletion in Local Group dwarfs on ~250 kpc scales: Ram pressure stripping assisted by internal heating at early times
Matthew Nichols, Joss Bland-Hawthorn
A recent survey of the Galaxy and M31 reveals that more than 90% of dwarf galaxies within 270 kpc of their host galaxy are deficient in HI gas. At such an extreme radius, the coron…
The Smith Cloud: high-velocity accretion and dark-matter confinement
M. Nichols, J. Bland-Hawthorn
The Smith Cloud is a massive system of metal-poor neutral and ionized gas M_gas >= 2x10^6 M_sun) that is presently moving at high velocity (V_GSR ~300 km s^-1) with respect to the…
