Tunneling spectroscopy measurements on one-dimensional superconducting hybrid materials have revealed signatures of Majorana fermions which are the edge states of a bulk topological superconducting phase. We couple strong spin-orbit semiconductor InSb nanowires to conventional superconductors (NbTiN, Al) to obtain additional signatures of Majorana fermions and to explore the topological phase transition. A potent alternative explanation for many of the...

Localization is one of the most staggering effects of quantum mechanics.The discovery of many-body localization makes the phenomenon even more broad, and suggests that the delocalization transition might give rise to a new paradigm of quantum dynamical phase transitions. In my talk I will explore the use of Wegner flow methods for analyzing the the delocalization transitions in disordered...

Recent advances in nanofabrication technology and in the development of two-dimensional (2D) crystals and heterostructures/interfaces of novel materials have enabled new possibilities to explore novel quantum states and manipulate different quantum degrees of freedom (e.g., spin, valley, symmetry, topology, etc.) in materials. For instance, 2D crystals of van der Waals (vdW) materials with honeycomb lattice structures, such as semi-metallic...

Anderson’s idea of a (short-ranged) resonating valence bond (RVB) spin liquid has been the first ever proposal of what we now call a topologically ordered phase. Since then, a wealth of exactly solvable lattice models has been constructed that have topologically ordered ground states. For a long time, however, it has been difficult to realize Anderson’s original vision, according...

Dynamical response functions of strongly correlated quantum systems provide crucial information about their complex physical behavior. For example, in layered high Tc superconductors, pairing could be linked to the unusual structure of spin excitations with a spin gap at low energies and a magnetic resonance with an universal hourglass dispersion. Angle resolved photoemission spectroscopy represents another invaluable tool, providing...

With the development of ultrabright electron sources capable of literally lighting up atomic motions, the fundamental space-time limit to imaging chemistry has been achieved. The first studies focused on relatively simple systems. Further advances in source brightness have opened up even complex organic systems and solution phase reaction dynamics to atomic inspection. A number of different chemical reactions will...

Feynman’s original vision for a quantum computer was of a physical quantum system whose Hamiltonian could be adjusted in situ in order to simulate the physics of other quantum systems. Quantum magnetic systems, with localized spins and short range interactions, are perhaps the simplest such physical quantum system that can be implemented in existing solid state technologies. This lecture...

One-dimensional (1D) magnetic materials have attracted significant interest as a platform for studying phenomena such as quasiparticle fractionalization and quantum criticality. The spin-1/2 1D Heisenberg antiferromagnet is a vital system; its elementary excitations are chargeless spin-1/2 quasiparticles called spinons that are created in pairs. While inelastic neutron scattering (INS) experiments observe the two-spinon continuum regularly, the presence of four-spinon...

The goal of this event is to promote real advances in the field of quantum control of matter. In particular, building on the advances in atomic and molecular physics, we will discuss possible new strategies to exploit the light-matter interaction at the quantum level to manipulate the properties of solids and create transient non-equilibrium states with no counterpart at...

This three-day workshop will bring together some of the leading experts in the study of strongly correlated materials and their properties, both from the theoretical and from the experimental side, to survey the status of this field. Presentations discussing various new materials, various experimental techniques and various theoretical and numerical approaches for studying them will be followed by extended,...
