Observation of a topological crystalline insulator phase and topological phase transition in Pb1-xSnxTe

A topological insulator protected by time-reversal symmetry is realized via spin-orbit interaction-driven band inversion. The topological phase in the Bi1-xSbx system is due to an odd number of band inversions. A related spin-orbit system, the Pb1-xSnxTe, ...

Neutron Scattering of Spin Waves in Square Lattice Quantum Antiferromagnets at high and low energies

Diane Virginie Marie Lançon

In the field of quantum magnetism, neutron scattering techniques allows probing of the magnetic properties of many materials, as the neutrons carry spin. Interesting materials are for example the parent compound of a high temperature superconductor La2CuO4 ...

Control of spin configuration in half-metallic La0.7Sr0.3MnO3 nano-structures

André Bisig

We investigate the interplay between the governing magnetic energy terms in patterned La0.7Sr0.3MnO3 (LSMO) elements by direct high-resolution x-ray magnetic microscopy as a function of temperature and geometrical parameters. We show that the magnetic conf ...

Long-Lived States to Monitor Protein Unfolding by Proton NMR

Geoffrey Bodenhausen, Aurélien Bornet, Paul Romeo Vasos, Riddhiman Sarkar, Puneet Ahuja

The relaxation of long-lived states (LLS) corresponds to the slow return to statistical thermal equilibrium between symmetric and antisymmetric proton spin states. This process is remarkably sensitive to the presence of external spins and can be used to ob ...

Theory of inelastic light scattering in spin-1 systems: Resonant regimes and detection of quadrupolar order

Frédéric Mila, Frédéric Alexis Michaud, François Vernay

Motivated by the lack of an obvious spectroscopic probe to investigate nonconventional order such as quadrupolar orders in spin S > 1/2 systems, we present a theoretical approach to inelastic light scattering for spin-1 quantum magnets in the context of a ...

Universal polarizer at 140 for DNP-enhanced NMR experiments

Stefano Alberti, Jean-Philippe Ansermet, Arnaud Comment, Emile Jacques de Rijk, Alessandro Macor

By shining mm-waves upon a sample containing unpaired electron spins, DNP provides a way to enhance NMR signals. We report the characterization of a universal polarizer for EM-waves at 140 GHz made by rectangular grooved mirrors as well as design considera ...

Dynamics of individual rotational states in an electrostatic guide for neutral molecules

Andreas Osterwalder, Benjamin Bertsche

The guiding properties of individual rotational states of deuterated ammonia inside an electrostatic hexapole guide are presented. The guide is combined with resonance enhanced multiphoton ionization detection to assess the guiding probabilities and veloci ...

Tuning the spin texture in binary and ternary surface alloys on Ag(111)

Klaus Kern, Jan Hugo Dil, Isabella Gierz

A giant spin splitting has been observed in surface alloys on noble metal (111) surfaces as a result of a strong structural modification at the surface as well as the large atomic spin-orbit interaction (SOI) of the alloy atoms. These surface alloys are an ...

Investigation of Two-Dimensional Electron Gases with Angular Resolved Photoemission Spectroscopy

Isabella Gierz

In this thesis we study the electronic structure of different two-dimensional (2D) electron systems with angular resolved photoemission spectroscopy (ARPES). This technique is based on the photoelectric effect and directly probes the electronic structure o ...

Relativistic effects in spectroscopy and photophysics of heavy-metal complexes illustrated by spin–orbit calculations of [Re(imidazole)(CO)3(phen)]+

Majed Chergui

Spin–orbit coupling (SOC) is an essential factor in photophysics of heavy transition metal com- plexes. By enabling efficient population of the lowest triplet state and its strong emission, it gives rise to a very interesting photophysical behavior and und ...
