Portfolio
Mathematica / DMRG / Non-Hermitian / Quantum Many-Body
Non-Hermitian Persistent Current
Using Green's function formalism, we introduce a non-Hermitian Fermi-Dirac distribution and derive an analytical expression for the persistent current that relies solely on the complex spectrum.
Mathematica / Magnon / Linear Response
Majorana-Magnon Interactions
We demonstrate the uniform magnonic mode, which spreads over the entire Yu-Shiba-Rusinov chain, becomes imprinted with the parity of the ground state and, moreover, can discriminate between Majorana and trivial zero modes.
TensorFlow / Quantum Machine Learning
Quantum Capsule Networks
We adopted the capsule network architecture into the field of quantum machine learning, which demonstrates a remarkable classification accuracy, showcases an exponential quantum speedup and paves a way to explore explainable quantum AI.
Julia / Quantum Computing / Machine Learning
Quantum Neuroevolution
We introduced a Markovian quantum neuroevolution algorithm (MQNE) that autonomously finds near-optimal quantum neural networks for different machine-learning tasks.
Mathematica / Condensed Matter / Majorana
Spin Josephson junctions
We found that inhomogeneous quantum spin chains support spin supercurrents, that enhance the entanglement between spins, and can be detected using dispersive techniques.
Python / High-Energy Astrophysics
Disc–jet couplings
We proposed a magnetized, radiatively efficient thin accretion disc model (M-thin) to scrutinize the disc–jet couplings, and further explain the radio/X-ray correlations in the black hole/neutron star X-ray binary.
Photography / Astronomy / Telescope
Solar Eclipse in Xiamen
An annular solar eclipse occurred on June 21, 2020. An airplane happened to be captured in my lens at 2:49 PM. This video was shot by iPhone XS Max via Sky-Watcher EQ3D in my avatar, without any Photoshop. This must be the luckiest day of my life!
