Correlations and renormalization of the electron-phonon coupling in the honeycomb Hubbard ladder and superconductivity in polyacene

Ronny Thomale

We have performed extensive density matrix renormalization group (DMRG) studies of the Hubbard model on a honeycomb ladder. The band structure (with Hubbard U = 0) exhibits an unusual quadratic band touching at half-filling, which is associated with a quan ...

Mobility engineering and a metal–insulator transition in monolayer MoS2

Andras Kis, Branimir Radisavljevic

Two-dimensional (2D) materials are a new class of materials with interesting physical properties and applications ranging from nanoelectronics to sensing and photonics. In addition to graphene, the most studied 2D material, monolayers of other layered mate ...

Polaronic Conductivity in the Photoinduced Phase of 1T-TaS2

Helmuth Berger

The transient optical conductivity of photoexcited 1T-TaS2 is determined over a three-order-of-magnitude frequency range. Prompt collapse and recovery of the Mott gap is observed. However, we find important differences between this transient metallic state ...

Real-Time Observation of Cuprates Structural Dynamics by Ultrafast Electron Crystallography

Fabrizio Carbone

The phonon-mediated attractive interaction between carriers leads to the Cooper pair formation in conventional superconductors. Despite decades of research, the glue holding Cooper pairs in high-temperature superconducting cuprates is still controversial, ...

Metal-insulator transition in graphite: A comparison to heterostructures with high carrier mobility

Dirk Grundler

Conditions for a transition from the insulator (I) to metal (M) state in the electron system of highly oriented pyrolytic graphite (HOPG) have been studied by means of magnetotransport measurements in a broad temperature range (0.3–150 K). In magnetic fiel ...

Study of novel electronic conductors

Neven Barisic

This thesis presents the results of a concerted effort to understand the complex array of physical properties exhibited by the BaVS3 family of materials. As a 3d1 system, BaVS3 displays a unique collection of correlation-driven phenomena, including a metal ...

Theory of Polaron States in Pyramidal GaAs/AlGaAs Quantum Dots

Danail Obreschkow

In this thesis we address the subject of strong electron-phonon coupling in pyramidal quantum dots and pursue detailed physical, analytical and numerical investigations. The strong coupling polaron states in a pyramidal GaAs/AlGaAs quantum dot are computed ...

Angle-resolved photoemission spectroscopic properties of quasi-one-dimensional crystals

Slobodan Mitrovic

Abstract Electronic properties of low-dimensional systems — and particularly quasi-one-dimensional systems — together with related correlated electron phenomena have for quite some time been at the very frontier of condensed matter physics. The interest ra ...
