Aharonov-Bohm Oscillations in Singly-Connected Disordered Conductors

I. L. Aleiner, A. V. Andreev, V. Vinokur

We show that transport and thermodynamic properties of \emph{singly-connected} disordered conductors exhibit quantum Aharonov - Bohm oscillations with the total magnetic flux throu…

Landau level spectroscopy of electron-electron interactions in graphene

C. Faugeras, S. Berciaud, P. Leszczynski +11

We present magneto-Raman scattering studies of electronic inter Landau level excitations in quasi-neutral graphene samples with different strengths of Coulomb interaction. The band…

Breakdown of Interference Rules in Azulene, a Non-Alternant Hydrocarbon

Jianlong Xia, Brian Capozzi, Sujun Wei +8

We have designed and synthesized five azulene derivatives containing gold- binding groups at different points of connectivity within the azulene core to probe the effects of quantu…

Adsorption-Induced Solvent-Based Electrostatic Gating of Charge Transport through Molecular Junctions

Michele Kotiuga, Pierre Darancet, Carlos R. Arroyo +2

Recent experiments have shown that transport properties of molecular-scale devices can be reversibly altered by the surrounding solvent. Here, we use a combination of first-princip…

Valley Splitting and Polarization by the Zeeman Effect in Monolayer MoSe2

Yilei Li, Jonathan Ludwig, Tony Low +12

We have measured circularly polarized photoluminescence in monolayer MoSe2 under perpendicular magnetic fields up to 10 T. At low doping densities, the neutral and charged excitons…

Highly confined low-loss plasmons in graphene-boron nitride heterostructures

Achim Woessner, Mark B. Lundeberg, Yuanda Gao +10

Graphene plasmons were predicted to possess ultra-strong field confinement and very low damping at the same time, enabling new classes of devices for deep subwavelength metamateria…

The formation of nonequilibrium steady states in interacting double quantum dots: When coherences dominate the charge distribution

R. Härtle, A. J. Millis

We theoretically investigate the full time evolution of a nonequilibrium double quantum dot structure from initial conditions corresponding to different product states (no entangle…

Resonant Spin Tunneling in Randomly Oriented Nanospheres of Mn Acetate

S. Lendinez, R. Zarzuela, J. Tejada +6

We report measurements and theoretical analysis of resonant spin tunneling in randomly oriented nanospheres of a molecular magnet. Amorphous nanospheres of Mn acetate have b…

Three-particle Complexes in Two-Dimensional Semiconductors

Bogdan Ganchev, Neil Drummond, Igor Aleiner +1

We map the three-body problem in two dimensions onto one particle in a three dimensional potential treatable by a purposely-developed boundary-matching-matrix method. We evaluate b…

Origin of photoresponse in black phosphorus photo-transistors

Tony Low, Michael Engel, Mathias Steiner +1

We study the origin of photocurrent generated in doped multilayer BP photo-transistors, and find that it is dominated by thermally driven thermoelectric and bolometric processes. T…

The Nature of Surface States on Vicinal Cu (775): An STM and Photoemission Study

Nader Zaki, Kevin Knox, Richard M. Osgood +4

We report ARPES and a set of in situ STM measurements on a narrow-terrace-width vicinal Cu(111) crystal surface, Cu(775), whose vicinal cut lies close to the transition between ter…

Unveiling the atomic structure of single-wall boron nanotubes

Jens Kunstmann, Viktor Bezugly, Hauke Rabbel +2

Despite recent successes in the synthesis of boron nanotubes (BNTs), the atomic arrangement of their walls has not yet been determined and many questions about their basic properti…

Propagating phonons coupled to an artificial atom

Martin V. Gustafsson, Thomas Aref, Anton Frisk Kockum +3

Quantum information can be stored in micromechanical resonators, encoded as quanta of vibration known as phonons. The vibrational motion is then restricted to the stationary eigenm…

Atomically thin p-n junctions with van der Waals heterointerfaces

Chul-Ho Lee, Gwan-Hyoung Lee, Arend M. van der Zande +10

Semiconductor p-n junctions are essential building blocks for modern electronics and optoelectronics. In conventional semiconductors, a p-n junction produces depletion regions of f…

Tunable Fractional Quantum Hall Phases in Bilayer Graphene

Patrick Maher, Lei Wang, Yuanda Gao +9

Symmetry breaking in a quantum system often leads to complex emergent behavior. In bilayer graphene (BLG), an electric field applied perpendicular to the basal plane breaks the inv…

Quantum Memory Effects in Disordered Systems and Their Relation to 1/f Noise

Yonah Lemonik, Igor Aleiner

We propose that memory effects in the conductivity of metallic systems can be produced by the same two levels systems that are responsible for the 1/f noise. Memory effects are ext…

Measurement of Collective Dynamical Mass of Dirac Fermions in Graphene

Hosang Yoon, Carlos Forsythe, Lei Wang +6

Individual electrons in graphene behave as massless quasiparticles. In surprising twist, it is inferred from plasmonic investigations that collectively excited graphene electrons m…
