Emergent particle-hole symmetry in the half-filled Landau level

Michael Mulligan, S. Raghu, and Matthew P. A. Fisher

Phys. Rev. B 94, 075101 (2016) - Published 1 August, 2016

Here, the authors investigate the possibility that particle-hole symmetry in the lowest Landau level at half filling arises as an emergent low-energy symmetry. Specifically, they start with the traditional approach to the half-filled Landau level: an effective field theory known as the composite Fermi liquid pioneered by Halperin, Lee, and Read. In this theory, composite fermions arise when flux is attached to electrons in a half-filled Landau level. However, an equivalent starting point is one where one starts with a filled Landau level, depletes electrons (or equivalently, adds holes) to the point of half filling. One then attaches flux to the holes, and the resulting composite hole description is another viable description of the half-filled Landau level. The authors construct a particle-hole symmetric theory by studying a system consisting of alternating quasi-one-dimensional strips of composite Fermi liquid (CFL) and composite hole liquid (CHL), both of which break particle-hole symmetry. Gauge invariance requires the existence of gapless edge modes at the interface between the CFL and CHL. Out of these modes, they construct a neutral Dirac fermion coupled to an emergent U(1) gauge field. Thus, at distances long compared to the strip width, they demonstrate that the system is described by a Dirac fermion coupled to an emergent gauge field, with an anti-unitary particle-hole symmetry, precisely the form conjectured recently by Son to be the low-energy description of a particle-hole symmetric half-filled Landau level.

Coulomb charging energy of vacancy-induced states in graphene

V. G. Miranda, Luis G. G. V. Dias da Silva, and C. H. Lewenkopf

Phys. Rev. B 94, 075114 (2016) - Published 8 August, 2016

Magnetism due to vacancies in graphene has been a controversial topic, with conflicting results in the literature. This work aims to shine some light on the discussion by calculating the charging energy U, a key measure that encodes the local electron-electron Coulomb interaction in the vacancy-induced state. By combining analytical and numerical tools, the authors obtain values of U reaching about 1 eV for typical micron-sized samples, which is significantly higher than the previous estimates. These results provide a strong theoretical support to the emergence of vacancy-mediated magnetism in bulk graphene with a dilute concentration of vacancies and are in agreement with recent experiments in the literature.

One-shot calculation of temperature-dependent optical spectra and phonon-induced band-gap renormalization

Marios Zacharias and Feliciano Giustino

Phys. Rev. B 94, 075125 (2016) - Published 12 August, 2016

Here, the authors demonstrate a new first-principles computational method for performing predictive calculations of the optical absorption spectra of solids at finite temperature, including both zero-point fluctuations and phonon-assisted optical transitions. The comparison between calculations and measurements for the case of silicon, diamond, and gallium arsenide shows that this new method is not only efficient, but also very accurate, and is capable of yielding absorption coefficients in agreement with experiment over several orders of magnitude.

Discrimination between spin-dependent charge transport and spin-dependent recombination in π-conjugated polymers by correlated current and electroluminescence-detected magnetic resonance

Marzieh Kavand, Douglas Baird, Kipp van Schooten, Hans Malissa, John M. Lupton, and Christoph Boehme

Phys. Rev. B 94, 075209 (2016) - Published 31 August, 2016

It has been corroborated in the past that Pauli blockade mechanisms of weakly spin-coupled charge carrier pairs undergoing transitions into doubly occupied singlet states are among the most dominant spin-selection rules influencing room-temperature magnetoresistance and luminescence of organic semiconductors. It has remained unclear though whether these pairs consist of equal or opposite charges, and thus, whether the spin-dependent transitions are recombination or charge transport processes. Here, the authors report on simultaneous transient measurements of electric current and optical emission changes in organic light emitting diodes due to pulsed magnetic resonance induced charge carrier spin manipulation. When a room-temperature steady-state current is changed magnetic resonantly, the electroluminescence changes show identical dynamic and magnetic resonant signatures, indicating that both observables are controlled by the same spin-dependent electronic process. However, a quantitative analysis of the optical emission change reveals that its magnitude significantly exceeds what is expected from the magnitude of the electrical current change, implying that the optical emission change occurs not only because of the device current change but also due to a change of the radiative recombination rate, thereby showing that the observed spin-dependent process is due to recombination, not transport.

Electronic band gaps and exciton binding energies in monolayer MoxW1−xS2 transition metal dichalcogenide alloys probed by scanning tunneling and optical spectroscopy

Albert F. Rigosi, Heather M. Hill, Kwang Taeg Rim, George W. Flynn, and Tony F. Heinz

Phys. Rev. B 94, 075440 (2016) - Published 29 August, 2016

Using optical absorption and scanning tunneling spectroscopy techniques, the authors investigate band-gap properties of single layers of transition metal dichalcogenide (TMDC) alloyed crystals (MoxW1-xS2). They observe a significant modulation of the excitonic transitions, quasiparticle band gaps, and exciton binding energies. These findings may hold promise for fundamental studies of intralayer phenomena and for potential applications of TMDC alloys in electronic and optoelectronic devices.

Phys. Rev. B 94, 075440 (2016) - Published 29 August, 2016

Using optical absorption and scanning tunneling spectroscopy techniques, the authors investigate band-gap properties of single layers of transition metal dichalcogenide (TMDC) alloyed crystals (MoxW1-xS2). They observe a significant modulation of the excitonic transitions, quasiparticle band gaps, and exciton binding energies. These findings may hold promise for fundamental studies of intralayer phenomena and for potential applications of TMDC alloys in electronic and optoelectronic devices.
