Hybridizing superconductivity with the quantum Hall effects has major potential for designing novel circuits capable of inducing and manipulating non-Abelian states. In this talk I will present our recent results on quantum Hall Josephson junctions based on graphene...

Liquids are traditionally described within classical physics, whereas solids require the tools of quantum mechanics. I will discuss how in nanoscale systems, this distinction no longer holds. The dynamics of liquids confined to nanometer-scale channels can couple to...

Resonant inelastic x-ray scattering (RIXS) allows to study electronic and magnetic excitations and their momentum and energy dependencies. For example, the absence of dd excitations at the interfaces of KTaO3 films suggests a deficiency of localized Ta 5d electrons...

Understanding and controlling strongly correlated many-body spin systems is one of the key challenges in modern condensed matter physics. Among the most promising experimental platforms for these explorations are semiconducting moiré materials (SMMs), which consist of...

In the Bardeen– Cooper–Schrieffer (BCS) theory, Cooper pairs are formed with zero total momentum, preserving both time and inversion symmetries. A finite momentum Cooper pairing can be induced by the Zeeman effect of magnetic fields, forming the...

When the period of an incommensurate charge density wave (ICDW) approaches a multiple of a lattice vector, the energy gain from locking the period can drive a transition into an intermediate near-commensurate (NC) state made of locally commensurate regions separated...

In quantum materials, electronic responses to electric and magnetic fields can manifest the quantum geometry of electronic wavefunctions. These geometrical properties are encoded in the Berry curvature, quantum metric, and quantum geometric connection. The Berry...

In this talk, I will briefly review the physics of two-dimensional vortex lattices in thin superconducting films. By exploring the interplay between magnetic field, thermal fluctuations and disorder, I will provide a short overview of the different glassy phases which...

Fractional Chern insulators (FCIs) are the lattice equivalent of the fractional quantum Hall effect, whereby the intrinsic properties of the lattice provide the necessary ingredients for the emergence of this strongly correlated phase. Their existence was first...
