About Our Lab
Our research focuses on quantum mechanical aspects of condensed matter systems in the areas of strongly-correlated and mesoscopic physics,
as seen by the entangled electrons or spins.
We are interested in many aspects of condensed matter physics and statistical physics,
with a particular focus on topology, fractionalization and entanglement in in quantum many-body systems.
Prospective goal
The prospective goal is to exploit state-of-the-art methods,
to enable unbiased diagnosis of novel phases and criticalities,
and to build effective theories from a microscopic viewpoint.
We hope the study on quantum many-body systems could provide deeper insight into
the quantum (field) theory and to unveil new mechanisms
beyond the standard paradigm.
Research interests
A major portion of the current research involves:
Topological states of matter in strongly correlated systems:
Topological orders, fractional excitations on geometrically frustrated lattices,
fractional quantum Hall effects, quantum spin liquids
Novel phases, emergent phenomena and collective states of matter in strongly-correlated systems and quantum materials,
especially focusing on the interplay between Coulomb interaction, spin exchange interaction and orbital, spin, charge degrees of freedom
Quantum criticality: Quantum fluctuations, quantum phase transitions, and conformal invariance
Mesoscopic phenomena in two-dimensional materials: electronic structure, quantum transport
properties and the quantum hall effects, especially the role of the
extrinsic (intrinsic) disorder, electron-electron interactions and
the interplay of interactions and disorder
Developing the state-of-the-art numerical methods and applying them to various models:
Exact diagonalization, Density-matrix renormalization group, Dynamical mean-field theory, etc.
Applications of quantum information concepts to quantum many-body systems,
understanding the emergent phenomena via the lens of quantum entanglement
