Quation of state for the dilute Bose gas in two dimensions at zero temperature |
A dilute homogeneous two-dimensional (2D) Bose gas at zero temperature is studied with an original method based on the two-body density-matrix representation. This method allows for considering renormalization of an arbitrary pairwise potential in a self-consistent manner, without the pseudopotential ?-function representation. Low density expansions are derived for the chemical potential, ground state energy, pair distribution function, kinetic and interaction energies. |

Entanglement entropy of two disjoint blocks in Ising spin chains |
I will present results about the scaling of the Renyi and entanglement entropy of two disjoint blocks of critical Ising models, as function of their sizes and separations.
I will present analytic results based on conformal field theory that are quantitatively checked in numerical simulations of both the quantum spin chain and the classical two dimensional Ising model.
Theoretical results match the ones obtained from numerical simulations only after taking properly into account the corrections induced by the finite length of the blocks to their leading scaling behavior. |

Three-sphere low Reynolds number swimmer near a wall |
Design and fabrication of artificial molecular machines are the subject of growing experimental and theoretical investigation.
Recently a simple swimmer is introduced. The swimmer consists of a central sphere that is connected to two other spheres with straight rods.
The system moves by varying the length of arms in a periodic but time irreversible manner. We study the influence of a wall on the dynamics of this three-sphere swimmer. |

Ferromagnetism vs. Antiferromagnetism in Double Quantum Dots:Results from the Bethe Ansatz |
I'll consider understanding the problem of transport through double quantum dots in the context of Bethe ansatz solutions to models thereof. I'll look at both transport in the linear regime where the problem is under good control. The transport through a double dot allows for considerable structure, even in the linear regime. I'll also consider briefly out-of-equilibrium transport. Here the problem is much more difficult and my comments will necessarily be elliptical. |

Relaxation dynamics after a quantum quench of the gapped XXZ spin-1/2 chain |
We study the dynamics of a quench-prepared domain wall state released into a system whose unitary time evolution is dictated by the Heisenberg spin-1/2 gapped antiferromagnetic chain Hamiltonian. Using exact wavefunctions and their overlaps with the domain wall state allows us to describe the release dynamics to high accuracy, up to the long-time limit, for ?nite as well as in?nite systems. The results for the in?nite system allows us to rigorously prove that the system in the gapped regime will not thermalize in the strict sense. |

Hydrodynamics of large scale structure formation: a “new” feature of (dark) matter
|
I will start with the basics of hydrodynamics and turbulence, and then motivate how this plays a role in cosmology. Next the two types of dark matter, galactic DM vs cluster DM, are discussed. The main part of the talk will deal with gravitational hydrodynamics, in its relation to (in)direct observations.
I will close with a summary and a quote. |

Quantum phases of a supersymmetric model of lattice fermions (test-talk for the Veldhoven meeting)
|
Systems of strongly-interacting fermions on a lattice can exhibit remarkable properties. We study a system where the kinetic and interaction terms are chosen such that it can be described by a supersymmetric Hamiltonian. For a one-dimensional system this model is solved analytically and shows quantum critical behavior. In two dimensions, the supersymmetry allows us to describe the number of ground states analytically. Typically we find that the number of ground states grows exponentially with the area of the system.
We call such systems superfrustrated. For certain 2D lattice, however, the growth is exponential in the linear size of the system. We will explain why we call these systems 'supertopological'. |
