Interacting spin-1 bosons in a two-dimensional optical lattice

We study, using quantum Monte Carlo (QMC) simulations, the ground state properties of spin-1 bosons trapped in a square optical lattice. The phase diagram is characterized by the mobility of the particles (Mott insulating or superfluid phase) and by their ...

Manifestation of the spin textures in the thermopower of MnSi

László Forró, Ana Akrap, Stevan Arsenijevic

To identify possible spin texture contributions to thermoelectric transport, we present a detailed temperature and pressure dependence of thermopower S in MnSi, as well as a lowtemperature study of S in a magnetic field. We find that S/T reconstructs the ( ...

Tensor network study of the Shastry-Sutherland model in zero magnetic field

Frédéric Mila

We simulate the Shastry-Sutherland model in two dimensions by means of infinite projected entangled-pair states (iPEPS)-a variational tensor network method where the accuracy can be systematically controlled by the so-called bond dimension. Besides the wel ...

Magnetic field-tuned localization of the5f-electrons in URu2Si2

Philip Johannes Walter Moll

We report Shubnikov-de Haas oscillation measurements within the high magnetic field (μ0H>39 T) magnetically polarized regime of URu2Si2, made possible using mesoscopic samples prepared by means of focused ion beam lithography. A significant change in the F ...

The Order-Parameter Symmetry and Fermi Surface Topology of 122 Fe-Based Superconductors: A Point-Contact Andreev-Reflection Study

Janusz Andrzej Karpinski

We report on the results of directional point-contact Andreev-reflection (PCAR) measurements in Ba(Fe1-x Co (x) )(2)As-2 single crystals and epitaxial c-axis oriented films with x=0.08 as well as in Ca(Fe1-x Co (x) )(2)As-2 single crystals with x=0.06. The ...

Thermopower as a Unique Tool to Probe Quantum Phase Transitions

Stevan Arsenijevic

In my thesis, transport measurements such as resistivity and, more importantly, thermopower S, were used to explore the phase diagram of bad metals. Bad metals are electronically correlated systems whose ground state lies close to a quantum phase transitio ...

Electronic and Magnetic Resonant Inelastic X-ray Study of Cuprates

Marco Guarise

More than twenty five years have passed since the discovery of the first copper oxide based superconductor La2-xBaxCuO4 in 1986, and the intriguing physics of cuprates superconductors continues to fascinate and challenge scientists from all over the world. ...

Spin density wave induced disordering of the vortex lattice in superconducting La(2−x)Sr(x)CuO(4)

Sandrine Gerber, Joël Mesot, Johan Juul Chang, Jonathan White

We use small-angle neutron scattering to study the superconducting vortex lattice in La2−xSrxCuO4 as a function of doping and magnetic field. We show that near optimally doping the vortex lattice coordination and the superconducting coherence length ξ are ...

Atomic-Layer Engineering of Oxide Superconductors

Davor Pavuna, Guy Joseph Günter Dubuis, Ivan Bozovic

Molecular beam epitaxy technique has enabled synthesis of atomically smooth thin films, multilayers, and superlattices of cuprates and other complex oxides. Such heterostructures show high temperature superconductivity and enable novel experiments that pro ...
