Topological Lattice Models with Constant Berry Curvature
Daniel Varjas, Ahmed Abouelkomsan, Kang Yang +1
Band geometry plays a substantial role in topological lattice models. The Berry curvature, which resembles the effect of magnetic field in reciprocal space, usually fluctuates thro…
Charge density waves and their transitions in anisotropic quantum Hall systems
Yuchi He, Kang Yang, Mark Oliver Goerbig +1
In recent experiments, external anisotropy has been a useful tool to tune different phases and study their competitions. In this paper, we look at the quantum Hall charge density w…
Exceptional Spin Liquids from Couplings to the Environment
Kang Yang, Siddhardh C. Morampudi, Emil J. Bergholtz
We establish the appearance of a qualitatively new type of spin liquid with emergent exceptional points when coupling to the environment. We consider an open system of the Kitaev h…
Collective excitations of quantum Hall states under tilted magnetic field
Kang Yang, Mark Goerbig, Benoît Douçot
We study the neutral excitations of fractional quantum Hall states in electronic systems of finite width where an external anisotropy is introduced by tilting the magnetic field. A…
Berry phase in superconducting multiterminal quantum dots
Benoit Doucot, Romain Danneau, Kang Yang +2
We report on the study of the non-trivial Berry phase in superconducting multiterminal quantum dots biased at commensurate voltages. Starting with the time-periodic Bogoliubov-de G…
Engineering the Floquet spectrum of superconducting multiterminal quantum dots
Régis Mélin, Romain Danneau, Kang Yang +2
Here we present a theoretical investigation of the Floquet spectrum in multiterminal quantum dot Josephson junctions biased with commensurate voltages. We first draw an analogy bet…
Competing Fractional Quantum Hall and Electron Solid Phases in Graphene
Shaowen Chen, Rebeca Ribeiro-Palau, Kang Yang +5
We report experimental observation of the reentrant integer quantum Hall effect in graphene, appearing in the N2 Landau level. Similar to high-mobility GaAs/AlGaAs heterostructu…
Hamiltonian theory for Quantum Hall systems in a tilted magnetic field: robustness of activation gaps
Kang Yang, Mark Oliver Goerbig, Benoît Douçot
We use the Hamiltonian theory developed by Shankar and Murthy to study a quantum Hall system in a tilted magnetic field. With a finite width of the system in the direction, the…
A discrete unified gas-kinetic scheme for immiscible two-phase flows
Chunhua Zhang, Kang Yang, Zhaoli Guo
In this work, we extend the discrete unified gas-kinetic scheme (DUGKS) [Guo et al., Phys. Rev. E 88, 033305 (2013)] to continue two-phase flows. In the framework of DUGKS, two kin…
Simple Floquet-Wannier-Stark-Andreev viewpoint and emergence of low-energy scales in a voltage-biased three-terminal Josephson junction
Régis Mélin, Jean-Guy Caputo, Kang Yang +1
A three-terminal Josephson junction consists of three superconductors coupled coherently to a small nonsuperconducting island, such as a diffusive metal, a single or double quantum…
The mutual energy current interpretation for quantum mechanics
Shuang-ren Zhao, Kevin Yang, Kang Yang +2
Quantum physics has the probability interpretation. From the knowledge of light, we know that wave is always spread out, and hence the electron wave should also spread out. That me…
The principle of the mutual energy
Shuang-ren Zhao, Kevin Yang, Kang Yang +2
Advanced potential solution of Maxwell equations isn't often accepted. We have proven if without advanced potential, it is not possible to satisfy the Maxwell equations. We also sh…
Image Reconstruction Image reconstruction by using local inverse for full field of view
Kang Yang, Kevin Yang, Xintie Yang +1
The iterative refinement method (IRM) has been very successfully applied in many different fields for examples the modern quantum chemical calculation and CT image reconstruction.…
A lattice Boltzmann method for binary fluids based on mass-conserved quasi-incompressible phase-field theory
Kang Yang, Zhaoli Guo
In this paper, a lattice Boltzmann equation (LBE) model is proposed for binary fluids based on a quasi-incompressible phase-field model [J. Shen et al, Comm. Comp. Phys. 13, 1045 (…
The modified Poynting theorem and the concept of mutual energy
Shuang-ren Zhao, Kevin Yang, Kang Yang +2
The goal of this article is to derive the reciprocity theorem, mutual energy theorem from Poynting theorem instead of from Maxwell equation. The Poynting theorem is generalized to…
