    Symposia Day (DCMMP - DPMCM) - Fluctuations, interactions and Disorder in Condensed Matter / Fluctuations, interactions et désordre dans la matière condensée
    Invited Speaker / Conférencier(ère) invité(e)

    The tunability of the stacking order in van der Waals materials provides a new and powerful method to engineer their physical properties. In parallel-stacked transition metal dichalcogenides, also known as the rhombohedral stacking order, the equilibrium atomic structure is asymmetric between layers, leading to a spontaneous electrical polarization across the vdW gap. Under an external...

    Symposia Day (DCMMP - DPMCM) - Fluctuations, interactions and Disorder in Condensed Matter / Fluctuations, interactions et désordre dans la matière condensée
    Invited Speaker / Conférencier(ère) invité(e)

    Quantum dimer magnets represent a textbook example of quantum magnetism, where nearest-neighbor spins entangle to form spin singlets (dimers). The excitations of the quantum dimer magnet are a triplet of Stot = 1 states, referred to as triplons. An applied magnetic field causes the lowest energy triplet state (Sz = 1) to be driven to degeneracy with the singlet ground state, resulting in...

    Symposia Day (DCMMP - DPMCM) - Fluctuations, interactions and Disorder in Condensed Matter / Fluctuations, interactions et désordre dans la matière condensée
    Invited Speaker / Conférencier(ère) invité(e)

    The quantum nature of materials spans microscopic to macroscopic scales. This enables a wide array of physical properties that facilitate applications such as energy relevant technologies. The exotic properties arise from intertwined couplings of symmetry, topology, dimensionality and strong correlations, and are sensitive to external stimuli. We can use this sensitivity to unravel the complex...
