Abstract The emergence of scalar Higgs-type amplitude modes in systems where symmetry is spontaneously broken has been a highly successful, paradigmatic description of phase transitions, with implications ranging from high-energy particle physics to

Abstract Recently, the observation of large thermal Hall conductivities in correlated insulators with no apparent broken symmetry has generated immense interest and debates on the underlying ground states. Here, considering frustrated magnets with bo

$$\alpha$$ α -RuCl$${}_{3}$$ 3 is a candidate Kitaev spin liquid but whether or not this is realised depends on the details of the magnetic interactions. Here, the authors use state-of-the-art numerical methods to predict that for a large parameter

Higher-order multipolar phases are unusual states that can form in correlated materials and are difficult to observe as they do not directly couple to conventional probes. Patri et al. theoretically show that angle-dependent magnetostriction measurem

Understanding how surface Fermi arcs connect different Weyl nodes in presence of multiple Weyl-node pairs is intriguing yet unclear. Here, Kimet al. show that the winding of the Zak phase around each projected Weyl node manifests itself as a topologi

We explain how gapped quantum spin liquids, both conventional and “fractonic,” may be unambiguously diagnosed experimentally using the technique of multidimensional coherent spectroscopy. “Conventional” nonchiral gapped quantum spin liquids (

In the electron dynamics in quantum matter, the Berry curvature of the electronic wave function provides the artificial magnetic field in momentum space, which leads to nontrivial contributions to transport coefficients. It is known that in the prese

Material realizations of the bond-dependent Kitaev interactions with S=1/2 local moments have vitalized the research in quantum spin liquids. Recently, it has been proposed that higher-spin analogs of the Kitaev interactions may also occur in a numbe

Recently, it was shown that the multipolar Kondo problem, wherein a quantum impurity carrying higher-rank multipolar moments interacts with conduction electrons, leads to novel non-Fermi liquid states. Because of the multipolar character of the local

Motivated by recent experimental and numerical progress on various cluster Mott insulators, we study an extended Hubbard model on a breathing kagome lattice with a single electron orbital and 1/6 electron filling. Two distinct types of cluster locali
