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...
