Zero point fluctuations for magnetic spirals and Skyrmions, and the fate of the Casimir energy in the continuum limit
B. Douçot, D. Kovrizhin, R. Moessner
We study the role of zero-point quantum fluctuations in a range of magnetic states which on the classical level are close to spin-aligned ferromagnets. These include Skyrmion textu…
Semi-classical Approach to Quantum Spin Ice
M. P. Kwasigroch, B. Douçot, C. Castelnovo
We propose a semi-classical description of the low-energy properties of quantum spin ice in the strong Ising limit. Within the framework of a semiclassical, perturbative Villain ex…
Realizing Topological Mott Insulators from the RKKY Interaction
Tianhan Liu, Benoît Douçot, Karyn Le Hur
We engineer topological insulating phases in a fermion-fermion mixture on the honeycomb lattice, without resorting to artificial gauge fields or spin-orbit couplings and considerin…
Strongly correlated hopping and many-body bound states
J. Vidal, B. Doucot
We study a system in which the quantum dynamics of electrons depend on the particle density in their neighborhood. For any on-site repulsive interaction, we show that the exact two…
Interaction induced delocalisation for two particles in a periodic potential
J. Vidal, B. Doucot, R. Mosseri +1
We consider two interacting particles evolving in a one-dimensional periodic structure embedded in a magnetic field. We show that the strong localization induced by the magnetic fi…
