Quantum Phase Transition in a Low-Dimensional Weakly Interacting Bose Gas

This thesis is devoted to the study of the effect of disorder on low-dimensional weakly interacting Bose gases. In particular, the disorder triggers a quantum phase transition in one dimension at zero temperature that is investigated here through the study ...

Fragmentation and the Bose-glass phase transition of the disordered one-dimensional Bose gas

Vincenzo Savona, Luca Fontanesi

We investigate the superfluid-insulator quantum phase transition in a disordered one-dimensional Bose gas in the mean-field limit by studying the probability distribution of the density. The superfluid phase is characterized by a vanishing probability to h ...

Phase-resolved imaging of confined exciton-polariton wave functions in elliptical traps

Benoît Marie Joseph Deveaud, Gaël Nardin, François Morier-Genoud, Barbara Pietka

We study the wave functions of exciton polaritons trapped in the elliptical traps of a patterned microcavity. A homodyne detection setup with numerical off-axis filtering allows us to retrieve the amplitude and the phase of the wave functions. Doublet stat ...

Superfluid to Bose-Glass Transition in a 1D Weakly Interacting Bose Gas

Vincenzo Savona, Luca Fontanesi

We study the one-dimensional Bose gas in spatially correlated disorder at zero temperature, using an extended density-phase Bogoliubov method. We analyze, in particular, the decay of the one-body density matrix and the behavior of the Bogoliubov excitation ...

Dzyaloshinskii-Moriya anisotropy and nonmagnetic impurities in the s=1/2 kagome system ZnCu3(OH)(6)Cl-2

Frédéric Mila, Bruce Normand, Salvatore Manmana, Ioannis Rousochatzakis

Motivated by recent nuclear magnetic resonance experiments on ZnCu3(OH)(6)Cl-2, we present an exact-diagonalization study of the combined effects of nonmagnetic impurities and Dzyaloshinskii-Moriya (DM) interactions in the s = 1/2 kagome antiferromagnet. T ...

Metastability of two-dimensional vortex glass in Bi2Sr2CaCu2O8+delta

László Forró, Helmuth Berger

The decoupled layer quasi-two-dimensional glass phase of c-axis vortices in optimally doped Bi2Sr2CaCu2O8+delta (BSCCO) exhibits low-temperature metastability, the onset temperature of which is coincident with the peak in depinning current for zero-field-c ...

Quantized Vortices in an Exciton-Polariton Condensate

Benoît Marie Joseph Deveaud, Konstantinos Lagoudakis

One of the most striking quantum effects in an interacting Bose gas at low temperature is superfluidity. First observed in liquid 4He, this phenomenon has been intensively studied in a variety of systems for its remarkable features such as the persistence ...

Competing orders in strongly correlated systems studied by transport measurements

Ana Akrap

Competing orders in strongly correlated systems lead to rich phase diagrams comprising many electronic phases, such as superconductivity, charge/spin density wave, charge order, or bad metallicity. These phases are generically sensitive to a variety of par ...

Chirality and Z2 vortices in a Heisenberg spin model on the kagome lattice

The phase diagram of the classical J1–J2 model on the kagome lattice is investigated by using extensive Monte Carlo simulations. In a realistic range of parameters, this model has a low-temperature chiral-ordered phase without long-range spin order. We sho ...

All the Disorder Mechanisms in the 13:58 Phases Come Together. Out of the Modulated Confusion Rises the Remarkable Phase Ce12.60Cd58.68(2)

The compound

Ce_{12.60}Cd_{58.68(2)}

is a metrically commensurate representative of the incommensurately modulated phase

Ce_{13}Cd_{57+\delta}

. It is most likely a lock-in phase. The structure, which was solved using seeding of the modulation from thos ...
