Non-Abelian Quantum Transport and Thermosqueezing Effects

open access: yesPRX Quantum, 2022
Modern quantum experiments provide examples of transport with noncommuting quantities, offering a tool to understand the interplay between thermal and quantum effects.

Symmetry-enforced nodal chain phonons

open access: yesnpj Quantum Materials, 2022
Topological phonons in crystalline materials have been attracting great interest. Most cases studied so far are direct generalizations of the topological states from electronic systems.

Temperature oscillation in one-dimensional superlattice induced by phonon localization

open access: yesNew Journal of Physics, 2022
Thermal transport properties and thermodynamic quantities often present anomalous behaviors in low-dimensional systems. In this paper, it is found that temperature oscillates spatially in one-dimensional harmonic and weakly anharmonic superlattice.

Controlled information transfer in continuous-time chiral quantum walks

open access: yesNew Journal of Physics, 2021
In this paper we investigate properties of continuous time chiral quantum walks, which possess complex valued edge weights in the underlying graph structure, together with an initial Gaussian wavefunction spread over a number of vertices.

Perfect absorption in complex scattering systems with or without hidden symmetries

open access: yesNature Communications, 2020
In the past, implementations of coherent perfect absorption relied on systems with symmetric conditions. Here, the authors demonstrate coherent perfect absorption in complex microwave scattering settings without requiring such symmetries.

Phonon chirality tuned through interface transmission in a one-dimensional atomic junction model

open access: yesNew Journal of Physics, 2018
There has been growing interest in revealing exotic properties of chiral phonons since they were found in honeycomb AB lattice, and very recently they were experimentally verified in a tungsten diselenide monolayer (2018 Science 359 579).

Theoretical study on quantum transport of carbon nanotubes for detecting toxic molecules: The role of dopants

open access: yesJournal of Electrochemical Science and Engineering, 2022
We study the effects of dopant atoms on quantum transport and adsorption properties of environmentally harmful (CO2), toxic (CO) and common (O2 and N2) molecules of carbon nanotubes (CNTs) based on the first-principles electronic structure and quantum ...

Quantum Pumping with Adiabatically Modulated Barriers in Three-Band Pseudospin-1 Dirac–Weyl Systems

open access: yesEntropy, 2019
In this work, pumped currents of the adiabatically-driven double-barrier structure based on the pseudospin-1 Dirac⁻Weyl fermions are studied. As a result of the three-band dispersion and hence the unique properties of pseudospin-1 Dirac⁻Weyl ...

Vibrationally assisted quantum energy pumps

open access: yesNew Journal of Physics, 2015
We show that directed energy transport in a linear array of coupled quantum dots can be achieved by a coherent coupling of each dot to a single coherently driven mechanical mode.
