Excitonic Josephson effect induced by interlayer tunneling current: robust evidence for exciton condensation
Ya-Fen Hsu, Jung-Jung Su
The Josephson effect can be regarded as a striking manifestation of exciton condensation. It has been suggested to tune the condensate phase of bilayer excitons by applying interla…
Role of the compensating current in the weak Josphson coupling regime: An extended study on excitonic Josephson junctions
Ya-Fen Hsu, Jung-Jung Su
Huang's experiment [Phys. Rev. Lett. , 156802 (2012)] found, in the quantum Hall bilayer of the Corbino geometry, the interlayer tunneling currents at two edges are couple…
Voltage-Controlled Magnetic Reversal in Orbital Chern Insulators
Jihang Zhu, Jung-Jung Su, Allan H. MacDonald
Chern insulator ferromagnets are characterized by a quantized anomalous Hall effect, and have so far been identified experimentally in magnetically-doped topological insulator (MTI…
Spatially-indirect Exciton Condensate Phases in Double Bilayer Graphene
Jung-Jung Su, Allan H. MacDonald
We present a theory of spatially indirect exciton condensate states in systems composed of a pair of electrically isolated Bernal graphene bilayers. The ground state phase diagram…
Microscopic Theory of Equilibrium Polariton Condensates
Fei Xue, Fengcheng Wu, Ming Xie +2
We present a microscopic theory of the equilibrium polariton condensate state of a semiconductor quantum well in a planar optical cavity. The theory accounts for the adjustment of…
Comment on "Giant Plasticity of a Quantum Crystal"
C. Zhou, C. Reichhardt, M. J. Graf +3
In their Letter, Haziot et al. [Phys. Rev. Lett. 110 (2013) 035301] report a novel phenomenon of giant plasticity for hcp Helium-4 quantum crystals. They assert that Helium-4 exhib…
Plastic response by dislocation glide in solid helium under dc strain rate loading
Caizhi Zhou, Jung-Jung Su, Matthias J. Graf +3
We develop a model for the gliding of dislocations and plasticity in solid He-4. This model takes into account the Peierls barrier, multiplication and interaction of dislocations,…
Defects and glassy dynamics in solid He-4: Perspectives and current status
A. V. Balatsky, M. J. Graf, Z. Nussinov +1
We review the anomalous behavior of solid He-4 at low temperatures with particular attention to the role of structural defects present in solid. The discussion centers around the p…
Dislocation induced anomalous softening of solid helium
Caizhi Zhou, Jung-Jung Su, Matthias J. Graf +3
The classical motion of gliding dislocation lines in slip planes of crystalline solid helium leads to plastic deformation even at temperatures far below the Debye temperature and c…
The role of glass dynamics in the anomaly of the dielectric function of solid helium
Jung-Jung Su, Matthias J. Graf, Alexander V. Balatsky
We propose that acousto-optical coupling of the electric field to strain fields around defects in disordered He is causing an increase of the dielectric function with decreasin…
Charge density wave in hidden order state of URuSi
Jung-Jung Su, Yonatan Dubi, Peter Woelfle +1
We argue that the hidden order state in URuSi will induce a charge density wave. The modulation vector of the charge density wave will be twice that of the hidden order sta…
The glassy response of double torsion oscillators in solid Helium-4
Matthias J. Graf, Jung-Jung Su, Hari P. Dahal +2
Single and double torsion oscillators have been used successfully to measure the anomalous change in resonant frequency and accompanying dissipation in solid He-4. We present a gla…
Shear modulus in viscoelastic solid He
Jung-Jung Su, Matthias J. Graf, Alexander V. Balatsky
The complex shear modulus of solid He exhibits an anomaly in the same temperature region where torsion oscillators show a change in period. We propose that the observed stiffen…
A glass anomaly in the shear modulus of solid He
Jung-Jung Su, Matthias J. Graf, Alexander V. Balatsky
The shear modulus of solid He exhibits an anomalous change of order 10%[1, 2] at low temperatures that is qualitatively similar to the much smaller frequency change in torsiona…
A glassy contribution to the heat capacity of hcp He solids
Jung-Jung Su, Matthias J. Graf, Alexander V. Balatsky
We model the low-temperature specific heat of solid He in the hexagonal closed packed structure by invoking two-level tunneling states in addition to the usual phonon contribut…
Critical Tunneling Currents in Quantum Hall Superfluids: Pseudospin-Transfer Torque Theory
Jung-Jung Su, Allan H. MacDonald
At total filling factor quantum Hall bilayers can have an ordered ground state with spontaneous interlayer phase coherence. The ordered state is signaled experimentally by dr…
How to make a bilayer exciton condensate flow
Jung-Jung Su, A. H. MacDonald
Bose condensation is responsible for many of the most spectacular effects in physics because it can promote quantum behavior from the microscopic to the macroscopic world. Bose con…
