Non-dispersing wave packets in lattice Floquet systems
Zhoushen Huang, Aashish Clerk, Ivar Martin
We show that in a one-dimensional translationally invariant tight binding chain, non-dispersing wave packets can in general be realized as Floquet eigenstates -- or linear combinat…
Entanglement Hamiltonian of Many-body Dynamics in Strongly-correlated Systems
W. Zhu, Zhoushen Huang, Yin-Chen He +1
A powerful perspective in understanding non-equilibrium quantum dynamics is through the time evolution of its entanglement content. Yet apart from a few guiding principles for the…
Reconstructing Entanglement Hamiltonian via Entanglement Eigenstates
W. Zhu, Zhoushen Huang, Yin-chen He
The entanglement Hamiltonian , defined through the reduced density matrix of a subsystem , is an important concept in understanding the nature of quantum entan…
Complexity and geometry of quantum state manifolds
Zhoushen Huang, Alexander V. Balatsky
We show that the Hilbert space spanned by a continuously parametrized wavefunction family---i.e., a quantum state manifold---is dominated by a subspace, onto which all member state…
Invariance of topological indices under Hilbert space truncation
Zhoushen Huang, W. Zhu, Daniel P. Arovas +2
We show that the topological index of a wavefunction, computed in the space of twisted boundary phases, is preserved under Hilbert space truncation, provided the truncated state re…
Dynamical quantum phase transitions: Role of topological nodes in wavefunction overlaps
Zhoushen Huang, Alexander V. Balatsky
A sudden quantum quench of a Bloch band from one topological phase toward another has been shown to exhibit an intimate connection with the notion of a dynamical quantum phase tran…
Odd frequency pairing of interacting Majorana fermions
Zhoushen Huang, P. Wolfle, A. V. Balatsky
Majorana fermions are rising as a promising key component in quantum computation. While the prevalent approach is to use a quadratic (i.e. non-interacting) Majorana Hamiltonian, wh…
Topological indices for open and thermal systems via Uhlmann's phase
Zhoushen Huang, Daniel P. Arovas
Two-dimensional topological phases are characterized by TKNN integers, which classify Bloch energy bands or groups of Bloch bands. However, quantization does not survive thermal av…
The fate and heir of Majorana zero modes in a quantum wire array
Da Wang, Zhoushen Huang, Congjun Wu
Experimental signatures of Majorana zero modes in a single superconducting quantum wire with spin-orbit coupling have been reported as zero bias peaks in the tunneling spectroscopy…
Impurity scattering in Weyl Semimetals and their stability classification
Zhoushen Huang, Daniel P. Arovas, Alexander V. Balatsky
Weyl Semimetals (WS) are a new class of Dirac-type materials exhibiting a phase with bulk energy nodes and an associated vanishing density of states (DOS). We investigate the stabi…
Stability of Weyl metals under impurity scattering
Zhoushen Huang, Tanmoy Das, Alexander V. Balatsky +1
We investigate the effects of bulk impurities on the electronic spectrum of Weyl semimetals, a recently identified class of Dirac-type materials. Using a -matrix approach, we st…
Edge States, Entanglement Spectra, and Wannier Functions in Haldane's Honeycomb Lattice Model and its Bilayer Generalization
Zhoushen Huang, Daniel P. Arovas
We study Haldane's honeycomb lattice model and a bilayer generalization thereof from the perspective of edge states, entanglement spectra, and Wannier function behavior. For the mo…
Entanglement spectrum and Wannier center flow of the Hofstadter problem
Zhoushen Huang, Daniel P. Arovas
We examine the quantum entanglement spectra and Wannier functions of the square lattice Hofstadter model. Consistent with previous work on entanglement spectra of topological band…
