I am interested in developing new methods for solving open quantum many-body systems. In particular, this is divided into a quantum approach and a classical one.
I am interested in developing new methods for solving open quantum many-body systems. In particular, this is divided into a quantum approach and a classical one.
The quantum approach involves designing new protocols for the quantum simulation of open quantum many-body systems. In particular, I have been investigating how giant atoms, a recently raised quantum optical platform, can be versatile for quantum simulation.

The classical approach involves developing new numerical tools to study open quantum many-body systems. In particular, I have developed the numerical library NHKPM.jl to compute dynamical correlators in non-Hermitian systems efficiently. This library is based on matrix-product states and the kernel polynomial method. Currently, I am generalizing this method to investigate Liouvillian dynamics in open quantum many-body systems.

Exotic phases in van der Waals materials
Exotic phases in van der Waals materials
Van der Waals materials are recently raised materials as versatile platforms for engineering. I am interested in how exotic phases of matter can be realized and probed in van der Waals materials with different ways of engineering. My past research has focused on identifying Dirac QSL with impurity and twist engineering, as well as driving 1T-TaS2 to the QSL regime with Coulomb engineering. I have collaborated with experimentalists on the STM characterization of aritificial heavy-fermions in 1T-TaS2/1H-TaS2 heterostructure and nodal superconductivity in 1H-TaS2.

Non-Hermitian many-body physics
Non-Hermitian many-body physics
Recently, non-Hermitian Hamiltonians have attracted much interest as an effective description of the dynamics of open quantum systems. While their properties have been relatively well-understood in 1D single-particle systems, unveiling their properties in the many-body regime represents a big challenge due to numerical difficulties. I have designed an algorithm to investigate 1D non-Hermitian spin models.
