Exact time evolution formulae in the XXZ spin chain with domain wall initial state
Jean-Marie Stéphan
We study the time evolution of the spin-1/2 XXZ chain initialized in a domain wall state, where all spins to the left of the origin are up, all spins to its right are down. The foc…
Ergodic Edge Modes in the 4D Quantum Hall Effect
Benoit Estienne, Blagoje Oblak, Jean-Marie Stéphan
The gapless modes on the edge of four-dimensional (4D) quantum Hall droplets are known to be anisotropic: they only propagate in one direction, foliating the 3D boundary into indep…
Cornering the universal shape of fluctuations
Benoit Estienne, Jean-Marie Stéphan, William Witczak-Krempa
Understanding the fluctuations of observables is one of the main goals in science, be it theoretical or experimental, quantum or classical. We investigate such fluctuations when on…
The boundary density profile of a Coulomb droplet. Freezing at the edge
Gabriel Cardoso, Jean-Marie Stéphan, Alexander G. Abanov
We revisit the problem of computing the boundary density profile of a droplet of two-dimensional one-component plasma (2D OCP) with logarithmic interaction between particles in a c…
Entanglement spectroscopy of chiral edge modes in the Quantum Hall effect
Benoit Estienne, Jean-Marie Stéphan
We investigate the entanglement entropy in the Integer Quantum Hall effect in the presence of an edge, performing an exact calculation directly from the microscopic two-dimensional…
Entanglement entropies of inhomogeneous Luttinger liquids
Alvise Bastianello, Jérôme Dubail, Jean-Marie Stéphan
We develop a general framework to compute the scaling of entanglement entropy in inhomogeneous one-dimensional quantum systems belonging to the Luttinger liquid universality class.…
