Postdoctoral Researcher · Institute of Theoretical Physics, Chinese Academy of Sciences
I study quantum gravity and holography, with a focus on how geometry encodes information in systems with black holes, boundaries and defects.
My work combines geometric reasoning, analytic field theory, numerical methods and AI-native research workflows.
01Boundary / surface / region
01 / Research
The common question is how geometric structure makes quantum information precise when boundaries, defects or gravitational sectors are present.
I study how entanglement and gravitational regions are represented by extremal geometric structures, especially in black-hole and brane-world settings.
I examine how boundaries and defects change holographic geometry, field-theory observables, and effective lower-dimensional gravitational descriptions.
I develop analytic and numerical checks for entanglement and interface problems, using lattice and Gaussian methods where they sharpen the continuum question.
02 / Selected publications
Selected by contribution to the trajectory rather than by citation count or chronology alone.
Combined an end-of-the-world brane with a finite holographic cutoff and derived the corresponding lower-dimensional brane-world description by partial reduction.
Derived the JT gravity action from transverse brane fluctuations in a three-dimensional partial-reduction construction and matched island and defect-extremal-surface entropies.
Derived Page curves from defect extremal surfaces, established precise agreement with the island formula in AdS₃/BCFT₂, and identified a higher-dimensional difference.
Introduced the defect extremal surface prescription and showed how the boundary quantum extremal surface emerges from a brane-world construction.
03 / Research systems
Alongside theoretical physics, I develop AI-assisted systems for literature analysis, symbolic derivation, numerical verification and manuscript auditing. Scientific judgment stays in the loop.
A reproducible derivation note with assumptions, verified steps and unresolved points separated.
An audit record that links each finding to a source location and a review status.
A self-contained Mathematica or Python record with explicit errors and reusable figures.
04 / Notes
A geometric explanation of why a quantum correction localized on a defect changes the surface that computes entropy.
When a diagram is useful, what has it actually compressed—and what assumptions can it hide?
A reproducible workflow for conventions, dependencies, limiting cases, and unresolved mismatches.
05 / Profile
I am a theoretical physicist working on holography, black-hole information and quantum gravity. My research often focuses on situations in which boundaries, defects or lower-dimensional gravitational sectors modify the relation between geometry and quantum information. I also build research systems that connect physical intuition, analytic derivation, numerical checks, literature and manuscript development.
