In the conventional theory of superconductivity the critical temperature Tc is determined by the electron-phonon coupling constant and the phonon cut-off frequency. The hallmark experiments of McMillan and Rowell demonstrated that bosons (phonons) responsible for pairing can be observed through the frequency dependence of the gap parameter. Determination of the electron-boson coupling strength in high-Tc cuprates is, however, not an easy task. One of the promising ways is to measure the energy relaxation rate of photoexcited carriers by using femtosecond real-time techniques. Here, considering the electron relaxation process within the conduction band, it is commonly assumed that the underlying Eliashberg electron-boson coupling function is independent of electron excess energy. Conversely, studies of light-induced suppression of superconductivity in Pr1.85Ce0.15CuO4 reported here imply a strong variation of the electron-boson coupling function on electron energy. Considering the competing scenarios of superconductivity being mediated by either phonons or magnetic excitations, the results suggest that high-energy electrons strongly couple either to phonons or magnetic modes, while the situation is reversed when considering pairing of low-energy electrons.

Collective electronic excitation in a trapped ensemble of photogenerated dipolar excitons and free holes revealed by inelastic light scattering

There have long been considerable efforts to study the many-body quantum phase diagram and quantum phase transitions of interacting bosonic particles in solid-state systems. The particular aim is the realization and identification of Bose-Einstein condensation, a coherent ground state with all particles condensed into a macroscopic many-body ground-state wave function. The authors probe photogenerated excitonic ensembles in coexistence with a two-dimensional hole system confined in GaAs double quantum well structures and electrostatically trapped by local gate electrodes using photoluminescence and resonant inelastic light scattering experiments. In this work, the authors observe a collective excitation mode at the transferred in-plane momentum and an energy of only 0.44 meV. This mode is interpreted as a plasma excitation of the two-dimensional excess hole subsystem coupled to the excitonic system. In this respect, the two subsystems behave like coupled oscillators. The plasmon energy is determined by the many-body interaction between the photogenerated exciton and hole subsystems. The low-energy excitation spectrum particularly of the excitonic system can play a key role in identifying Bose-Einstein condensation of excitonic ensembles, where, for example, roton excitations are expected.

Interplay between Rashba interaction and electromagnetic field in the edge states of a two-dimensional topological insulator

Fabrizio Dolcini

Phys. Rev. B 95, 085434 (2017) - Published 24 February, 2017

The author investigates in a nonperturbative way the effects of Rashba interaction and electromagnetic field on the edge states of a two-dimensional topological insulator. He shows that the electron dynamics is equivalent to a problem of massless Dirac fermions propagating with an inhomogeneous velocity, unveiling interesting consequences. The Rashba coupling always enhances the electron velocity and, despite the inelastic and time-reversal breaking processes induced by the electromagnetic field, no backscattering occurs without interaction. Furthermore, when the photoexcitation occurs far from the Rashba region, the latter effectively acts as a “superluminal gate”, boosting the photoexcited wavepacket outside the light-cone determined by the bare Fermi velocity vF. In contrast, for an electric pulse overlapping the Rashba region, the emerging wave packets are squeezed in a manner that depends on the overlap area. The author also discusses the effects of electron-electron interaction, for both intraspin and interspin density-density coupling. The results suggest that Rashba interaction, often considered as an unwanted disorder effect, may be exploited to tailor the shape and the propagation time of photoexcited spin-polarized wave packets.

There have long been considerable efforts to study the many-body quantum phase diagram and quantum phase transitions of interacting bosonic particles in solid-state systems. The particular aim is the realization and identification of Bose-Einstein condensation, a coherent ground state with all particles condensed into a macroscopic many-body ground-state wave function. The authors probe photogenerated excitonic ensembles in coexistence with a two-dimensional hole system confined in GaAs double quantum well structures and electrostatically trapped by local gate electrodes using photoluminescence and resonant inelastic light scattering experiments. In this work, the authors observe a collective excitation mode at the transferred in-plane momentum and an energy of only 0.44 meV. This mode is interpreted as a plasma excitation of the two-dimensional excess hole subsystem coupled to the excitonic system. In this respect, the two subsystems behave like coupled oscillators. The plasmon energy is determined by the many-body interaction between the photogenerated exciton and hole subsystems. The low-energy excitation spectrum particularly of the excitonic system can play a key role in identifying Bose-Einstein condensation of excitonic ensembles, where, for example, roton excitations are expected.

Interplay between Rashba interaction and electromagnetic field in the edge states of a two-dimensional topological insulator

The author investigates in a nonperturbative way the effects of Rashba interaction and electromagnetic field on the edge states of a two-dimensional topological insulator. He shows that the electron dynamics is equivalent to a problem of massless Dirac fermions propagating with an inhomogeneous velocity, unveiling interesting consequences. The Rashba coupling always enhances the electron velocity and, despite the inelastic and time-reversal breaking processes induced by the electromagnetic field, no backscattering occurs without interaction. Furthermore, when the photoexcitation occurs far from the Rashba region, the latter effectively acts as a “superluminal gate”, boosting the photoexcited wavepacket outside the light-cone determined by the bare Fermi velocity vF. In contrast, for an electric pulse overlapping the Rashba region, the emerging wave packets are squeezed in a manner that depends on the overlap area. The author also discusses the effects of electron-electron interaction, for both intraspin and interspin density-density coupling. The results suggest that Rashba interaction, often considered as an unwanted disorder effect, may be exploited to tailor the shape and the propagation time of photoexcited spin-polarized wave packets.
