Derivation of the Hartree dynamics for a N-particles fermionic 2D system interacting via long-range electric and magnetic two-body singular potentials in a dilute regime

Théotime Girardot

We show that a 2-dimensional system of N fermions interacting through a pairwise electric and magnetic singular interactions with Slater initial data preserves its Slater structure…

Microscopic derivation of the stationary Chern-Simons-Schrödinger equation for almost-bosonic anyons

Alireza Ataei, Douglas Lundholm, Théotime Girardot

In this work we consider the -body Hamiltonian describing the microscopic structure of a quantum gas of almost-bosonic anyons. This description includes both extended magnetic f…

Derivation of the Chern-Simons-Schrödinger equation from the dynamics of an almost-bosonic-anyon gas

Théotime Girardot, Jinyeop Lee

We study the time evolution of an initial product state in a system of almost-bosonic-extended-anyons in the large-particle limit. We show that the dynamics of this system can be w…

The free energy of dilute Bose gases at low temperatures interacting via strong potentials

S. Fournais, L. Junge, T. Girardot +3

We consider a dilute Bose gas in the thermodynamic limit and prove a lower bound on the free energy for low temperatures which is in agreement with the conjecture of Lee-Huang-Yang…

Lower bounds on the energy of the Bose gas

Søren Fournais, Theotime Girardot, Lukas Junge +2

We present an overview of the approach to establish a lower bound to the ground state energy for the dilute, interacting Bose gas in a periodic box. In this paper the size of the b…

Semiclassical limit for almost fermionic anyons

Théotime Girardot, Nicolas Rougerie

In two-dimensional space there are possibilities for quantum statistics continuously interpolating between the bosonic and the fermionic one. Quasi-particles obeying such statistic…
