On the Equivalence between Spin and Charge Dynamics of the Fermi Hubbard Model
Hui Zhai, Ning Sun, Jinlong Yu +1
Utilizing the Fermi gas microscope, recently the MIT group has measured the spin transport of the Fermi Hubbard model starting from a spin-density-wave state, and the Princeton gro…
Resonant Driving induced Ferromagnetism in the Fermi Hubbard Model
Ning Sun, Pengfei Zhang, Hui Zhai
In this letter we consider quantum phases and the phase diagram of a Fermi Hubbard model under periodic driving that has been realized in recent cold atom experiments, in particula…
Three-Body Problem of Bosons nearby a d-wave Resonance
Juan Yao, Pengfei Zhang, Ran Qi +1
Motivated by recent experimental progresses, we investigate few-body properties of interacting spinless bosons nearby a d-wave resonance. Using the Skorniakov-Ter-Martirosion (STM)…
Quantum Chaos for the Unitary Fermi Gas from the Generalized Boltzmann Equations
Pengfei Zhang
In this paper, we study the chaotic behavior of the unitary Fermi gas in both high and low temperature limits by calculating the Quantum Lyapunov exponent defined in terms of the o…
Dephasing-insensitive quantum information storage and processing with superconducting qubits
Qiujiang Guo, Shi-Biao Zheng, Jianwen Wang +11
A central task towards building a practical quantum computer is to protect individual qubits from decoherence while retaining the ability to perform high-fidelity entangling gates…
Deep Learning Topological Invariants of Band Insulators
Ning Sun, Jinmin Yi, Pengfei Zhang +2
In this work we design and train deep neural networks to predict topological invariants for one-dimensional four-band insulators in AIII class whose topological invariant is the wi…
Visualizing Neural Network Developing Perturbation Theory
Yadong Wu, Pengfei Zhang, Huitao Shen +1
In this letter, motivated by the question that whether the empirical fitting of data by neural network can yield the same structure of physical laws, we apply the neural network to…
Topological Sachdev-Ye-Kitaev Model
Pengfei Zhang, Hui Zhai
In this letter we construct a large-N exactly solvable model to study the interplay between interaction and topology, by connecting Sacheve-Ye-Kitaev (SYK) model with constant hopp…
Energy absorption spectroscopy of unitary Fermi gases in a uniform potential
Pengfei Zhang, Zhenhua Yu
We propose to use the energy absorption spectroscopy to measure the kinetic coefficients of unitary Fermi gases in a uniform potential. We show that in our scheme, the energy absor…
Universal relations for spin-orbit coupled Fermi gas near an s-wave resonance
Pengfei Zhang, Ning Sun
The synthetic spin-orbit coupled quantum gases is widely studied both experimentally and theoretically in recent years. As previous studies show, this modification of single-body d…
