Quantum spin liquids (QSLs) are novel phases of matter displaying fractionalized excitations and supporting emergent gauge fields. Despite numerous well-established theoretical proposals, conclusively linking experimental results to a QSL phase is a central challenge in modern studies of frustrated magnets. A key issue in understanding some QSL candidates is the interplay of weak structur…
This project focuses on some important problems in the physics of quantum materials. These are materials that allow us to explore emergent quantum phenomena with potential uses in future technologies. The types of systems to which we devote our efforts are transition metal oxides, heavy fermion systems, unconventional superconductors, quantum spin liquids, doped semiconductors, topologica…
Landau's theory of phase transitions is the cornerstone of our modern understanding of Condensed Matter Physics. The ability to characterize ordered states of matter, and their low-lying excitations, in terms of a local order parameter and the accompanying spontaneous symmetry breaking, is a very powerful and unifying idea. However, since the discovery of the quantum Hall effect, it was r…
The concepts of order, disorder, and spontaneous symmetry breaking - as initially formalized in Landau's seminal work on Phase Transitions - constitute the bases of our modern understanding of several exciting phenomena in Condensed Matter Physics. Recently, however, our view of these basic concepts was substantially expanded, primarily because of the frustrated magnets. Every day, novel …
Disorder is ubiquitous in solids. In magnets with localized spin moments, typical examples of disorder are missing or extra spins, arising, e.g., from chemical substitution. In this project, we study two classes of disordered magnets: with and without long range magnetic order. For magnets which display a ground state with long range magnetic order, we consider the effects of impurities, …
Understanding and controlling non-equilibrium many-body quantum systems is a topic of interest in modern physics, primarily motivated by the advent of quantum simulators, for example, based on Rydberg atoms. These systems allow us to study fundamental concepts such as quantum ergodicity, which explains how the unitary evolution of an isolated system can lead to an equilibrium state descri…
Geometric frustration is the inability to satisfy all local interactions simultaneously in systems of localized magnetic moments, which can lead to a large degeneracy of ground states. In this project, we want to study the paradigmatic system of magnetic frustration: the antiferromagnetic Ising model in the triangular lattice, in which frustration prevents the formation of long-range orde…

In quantum magnets, competing exchange interactions and geometric frustration can lead to unconventional magnetic states, as non-coplanar spin structures, or even disordered states, as spin liquids. The search for quantum spin liquids represents the challenge of understanding the novel phases beyond the standard Landau theory of phase transitions rooted in the concept of spontaneous symme…
Motivated by the recent experimental realization of a heavy-fermion quasicrystal lattice, we would like to investigate the low-temperature behavior of localized spins living in a quasicrystal. Specifically, we will study the antiferromagnetic Ising model in the two-dimensional octagonal, or Ammann-Beenker, tiling. Previous studies show that this system displays long-range order in its gro…
Motivated by a recent experimental realization of a heavy-fermion quasicrystal lattice, we would like to investigate the RKKY interaction between impurity spins placed in a metallic quasicrystal. Our goal is to observe how the effective coupling between the spins varies as a function of the electronic density and temperature. We will calculate the spectral properties using the Kernel Poly…

Over the last few years, much attention has been devoted to investigating exotic phases of matter in spin-orbit Mott insulators, which are stabilized due to the combination of strong spin-orbit coupling and electronic correlations. A prime example is the Kitaev spin liquid for S=1/2, where the local moments fractionalize into Majorana fermions and static Z2 fluxes. A natural question is …
We will investigate in this project exotic phases of matter which emerge due tothe combination of strong spin-orbit coupling and electronic correlations, giving raisethe so-called spin-orbit Mott insulators. As systems of interest, we have in mindthe materials alpha-RuCl3 and A2IrO3 (A=Na, Li), which are well described by theHeisenberg-Kitaev model. In particular, we focus on the alpha-Ru…
