Quantum Phase Transitions and Fractional Quantized Anomalous Hall Insulators in Rhombohedral Graphene
Zach Hadjri, Xinlei Yue, Tonghang Han +10
Fractional quantum anomalous Hall effect (FQAHE) has been discovered in twisted MoTe and rhombohedral graphene/hBN moiré superlattices. Such van der Waals heterostructures feat…
Aharonov-Bohm Interference in Even-Denominator Fractional Quantum Hall States
Jehyun Kim, Himanshu Dev, Amit Shaer +9
Position exchange of non-Abelian anyons affects the quantum state of their system in a topologically-protected way. Their expected manifestations in even-denominator fractional qua…
Mapping Driven Oscillations in the Size of a Bubble to the Dynamics of a Newtonian Particle in a Potential
Uri Shimon, Ady Stern
The non-linear dynamics of driven oscillations in the size of a spherical bubble are mapped to the dynamics of a Newtonian particle in a potential within the incompressible liquid…
Even Integer Quantum Hall Effect in Materials with Hidden Spin Texture
Daniel Kaplan, Ady Stern, Binghai Yan
Because spin-orbit coupling (SOC) is invisible in the band structure when inversion symmetry exists, whether spins are trivially degenerate or strongly coupled to momentum due to S…
Even-integer Quantum Hall Effect in an Oxide Caused by Hidden Rashba Effect
Jingyue Wang, Junwei Huang, Daniel Kaplan +17
In the presence of high magnetic field, quantum Hall systems usually host both even- and odd-integer quantized states because of lifted band degeneracies. Selective control of thes…
Theory of Half-Integer Fractional Quantum Spin Hall Insulator Edges
Julian May-Mann, Ady Stern, Trithep Devakul
We study the edges of fractional quantum spin Hall insulators (FQSH) with half-integer spin Hall conductance. These states can be viewed as symmetric combinations of a spin-up and…
Aharonov-Bohm interference and the evolution of phase jumps in fractional quantum Hall Fabry-Perot interferometers based on bi-layer graphene
Jehyun Kim, Himanshu Dev, Ravi Kumar +8
Quasi-particles in fractional quantum Hall states are collective excitations that carry fractional charge and anyonic statistics. While the fractional charge affects semi-classical…
Current Induced Hidden States in Josephson Junctions
Shaowen Chen, Seunghyun Park, Uri Vool +8
Josephson junctions enable dissipation-less electrical current through metals and insulators below a critical current. Despite being central to quantum technology based on supercon…
Vortex shear effects in layered superconductors
V. Braude, A. Stern
Motivated by recent transport and magnetization measurements in BSCCO samples [B. Khaykovich et. al., Phys. Rev. B 61, R9261 (2000)], we present a simple macroscopic model describi…
Theory of interlayer tunneling in bi-layer quantum Hall ferromagnets
Ady Stern, S. M. Girvin, A. H. MacDonald +1
Spielman et al. have recently observed a large zero-bias peak in the tunnel conductance of a bi-layer system in a quantum Hall ferromagnet state. We argue that disorder-induced top…
Dissipationless transport in low density bilayer systems
Ady Stern, S. Das Sarma, Matthew P. A. Fisher +1
In a bilayer electronic system the layer index may be viewed as the z-component of an isospin-1/2. An XY isospin-ordered ferromagnetic phase was observed in quantum Hall systems an…
Composite Fermions with Orbital Magnetization
Steven H. Simon, Ady Stern, Bertrand I. Halperin
For quantum Hall systems, in the limit of large magnetic field (or equivalently small electron band mass ), the static response of electrons to a spatially varying magnetic fi…
