Extreme statistics as a probe of the superfluid to Bose-glass Berezinskii-Kosterlitz-Thouless transition
Jeanne Colbois, Natalia Chepiga, Shaffique Adam +2
Recent studies of delocalization-localization transitions in disordered quantum chains have highlighted the role of rare, chain-breaking events that favor localization, in particul…
Long-range resonances in quasiperiodic many-body localization
Ashirbad Padhan, Jeanne Colbois, Fabien Alet +1
We investigate long-range resonances in quasiperiodic many-body localized (MBL) systems. Focusing on the Heisenberg chain in a deterministic Aubry-André potential, we complement st…
Cat states carrying long-range correlations in the many-body localized phase
Nicolas Laflorencie, Jeanne Colbois, Fabien Alet
Despite considerable efforts over the last decade, the high-energy phase diagram of the random-field Heisenberg chain still eludes our understanding, in particular the nature of th…
Topological Devil's staircase in a constrained kagome Ising antiferromagnet
Afonso Rufino, Samuel Nyckees, Jeanne Colbois +1
We show that the constrained Ising model on the kagome lattice with infinite first and third neighbor couplings undergoes an infinite series of thermal first-order transitions at w…
Statistics of systemwide correlations in the random-field XXZ chain: Importance of rare events in the many-body localized phase
Jeanne Colbois, Fabien Alet, Nicolas Laflorencie
Motivated by recent debates around the many-body localization (MBL) problem, and in particular its stability against systemwide resonances, we investigate long-distance spin-spin c…
Interaction-Driven Instabilities in the Random-Field XXZ Chain
Jeanne Colbois, Fabien Alet, Nicolas Laflorencie
Despite enormous efforts devoted to the study of the many-body localization (MBL) phenomenon, the nature of the high-energy behavior of the Heisenberg spin chain in a strong random…
Critical line of the triangular Ising antiferromagnet in a field from a -symmetric corner transfer matrix algorithm
Samuel Nyckees, Afonso Rufino, Frédéric Mila +1
The corner transfer matrix renormalization group (CTMRG) algorithm has been extensively used to investigate both classical and quantum two-dimensional (2D) lattice models. The conv…
Breaking the chains: extreme value statistics and localization in random spin chains
Jeanne Colbois, Nicolas Laflorencie
Despite a very good understanding of single-particle Anderson localization in one-dimensional (1D) disordered systems, many-body effects are still full of surprises, a famous examp…
Partial lifting of degeneracy in the Ising antiferromagnet on the kagome lattice
Jeanne Colbois, Bram Vanhecke, Laurens Vanderstraeten +3
Motivated by dipolar-coupled artificial spin systems, we present a theoretical study of the classical Ising antiferromagnet on the kagome lattice. We establish the gr…
Artificial out-of-plane Ising antiferromagnet on the kagome lattice with very small further neighbour couplings
Jeanne Colbois, Kevin Hofhuis, Zhaochu Luo +4
Despite their simple formulation, short range classical antiferromagnetic Ising models on frustrated lattices give rise to exotic phases of matter, in particular due to their macro…
Identifying the Huse-Fisher universality class of the three-state chiral Potts model
Samuel Nyckees, Jeanne Colbois, Frédéric Mila
Using the corner-transfer matrix renormalization group approach, we revisit the three-state chiral Potts model on the square lattice, a model proposed in the eighties to describe c…
Solving frustrated Ising models using tensor networks
Bram Vanhecke, Jeanne Colbois, Laurens Vanderstraeten +2
Motivated by the recent success of tensor networks to calculate the residual entropy of spin ice and kagome Ising models, we develop a general framework to study frustrated Ising m…
Probing the topology of the quantum analog of a classical skyrmion
O. M. Sotnikov, V. V. Mazurenko, J. Colbois +3
In magnetism, skyrmions correspond to classical three-dimensional spin textures characterized by a topological invariant that keeps track of the winding of the magnetization in rea…
Quantum Nanoskyrmions
O. M. Sotnikov, V. V. Mazurenko, J. Colbois +3
Skyrmions in condensed matter physics appear as classical topological spin structures. This nontrivial state can be obtained solving the corresponding micromagnetic model, where th…
