Engineering random spin models with atoms in a high-finesse cavity

Jean-Philippe Brantut, Nick Jacob Sauerwein, Tigrane Arthur Cantat Moltrecht

Random spin models play a key role in our understanding of disorder and complex many-body systems. Two all-to-all interacting, disordered models have now been realized using a cavity quantum electrodynamics platform. ...

Information Processing Biases: The Effects of Negative Emotional Symptoms on Sampling Pleasant and Unpleasant Information

Steffen Alexander Herff

Although theories of emotion associate negative emotional symptoms with cognitive biases in information processing, they rarely specify the details. Here, we characterize cognitive biases in information processing of pleasant and unpleasant information, an ...

Identification of biopsychological trait markers in functional neurological disorders

Serafeim Loukas

Weber et al. provide evidence in support of a stress-diathesis model of functional neurological disorders. They identify trauma history in the form of emotional neglect as a psychological risk factor, and reduced hippocampus and amygdala volume as a predis ...

Structural control energy of resting-state functional brain states reveals less cost-effective brain dynamics in psychosis vulnerability

Dimitri Nestor Alice Van De Ville, Marie Schaer

How the brain's white-matter anatomy constrains brain activity is an open question that might give insights into the mechanisms that underlie mental disorders such as schizophrenia. Chromosome 22q11.2 deletion syndrome (22q11DS) is a neurodevelopmental dis ...

Maladaptive emotion regulation traits predict altered corticolimbic recovery from psychosocial stress

Dimitri Nestor Alice Van De Ville

Background: Adaptive recovery from stress promotes healthy cognitive affective functioning, whereas maladaptive recovery is linked to poor psychological outcomes. Neural regions, like the anterior cingulate and hippocampus, play critical roles in psychosoc ...

Effects of paternal and peripubertal stress on aggression, anxiety, and metabolic alterations in the lateral septum

Maria del Carmen Sandi Perez, Nathalie Just, Maria Isabel Cordero Campana, Guillaume Poirier

Early-life stress and biological predispositions are linked to mood and personality disorders related to aggressive behavior. We previously showed that exposure to peripubertal stress leads to increased anxiety-like behaviors and aggression against males a ...

Structural disorder versus chiral magnetism in

Philip Pattison

The crystal structure of a disordered form of Cr1/3NbS2 has been characterized using diffraction and inelastic scattering of synchrotron radiation. In contrast to the previously reported symmetry (P6322), the crystal can be ...

Structure of EspB, a secreted substrate of the ESX-1 secretion system of Mycobacterium tuberculosis

Stewart Cole, Florence Pojer, Jérémie Piton, Aleksandre Japaridze

Mycobacterium tuberculosis secretes multiple virulence factors during infection via the general Sec and Tat pathways, and via specialized ESX secretion systems, also referred to as type VII secretion systems. The ESX-1 secretion system is an important viru ...

Hyper-emotional neurophysiology in a rat model of autism

Mônica Regina Favre

Autism is a pervasive neurodevelopmental disorder of unknown etiology, characterized by a spectrum of symptoms of social impairment, abnormal communication, and unusual restricted, inflexible behaviors. Patients also frequently present various levels of se ...

Coherence and Topological Defects in Exciton-Polariton Condensates

Francesco Manni

Exciton-polaritons are hybrid quasi-particles, eigenstates of the strong coupling regime between light and matter. Their Bose-Einstein condensation has been recently demonstrated, opening the way to several fundamental investigations on the associated phen ...

Hybridization of wave functions in one-dimensional localization

Dmitri Ivanov

A quantum particle can be localized in a disordered potential, the effect known as Anderson localization. In such a system, correlations of wave functions at very close energies may be described, due to Mott, in terms of a hybridization of localized states ...

Cognitive disorganisation in schizotypy is associated with deterioration in visual backward masking

Michael Herzog, Christine Mohr, Daniela Herzig

To understand the causes of schizophrenia, a search for stable markers (endophenotypes) is ongoing. In previous years, we have shown that the shine-through visual backward masking paradigm meets the most important characteristics of an endophenotype. Here, ...

Extracellular matrix in angiogenesis: dynamic structures with translational potential

Jeffrey Alan Hubbell

The vascular network is an integral component of most organs. Beyond assuring an adequate supply of oxygen and nutrients for normal tissue function, vascular structures provide also a critical interface in the balance of tissue homoeostasis and immune func ...

Electromagnetic modes of a disordered photonic crystal

Vincenzo Savona

We present a systematic numerical approach to compute the eigenmodes and the related eigenfrequencies of a disordered photonic crystal, characterized by small fluctuations of the otherwise periodic dielectric profile. The field eigenmodes are expanded on t ...

Mean-field phase diagram of the one-dimensional Bose gas in a disorder potential

Vincenzo Savona, Luca Fontanesi

We study the quantum phase transition of the 1D weakly interacting Bose gas in the presence of disorder. We characterize the phase transition as a function of disorder and interaction strengths, by inspecting the long-range behavior of the one-body density ...

Dynamics of Long-Range Ordering in an Exciton-Polariton Condensate

Benoît Marie Joseph Deveaud, Gaël Nardin, Konstantinos Lagoudakis, Barbara Pietka

We report on time-resolved measurements of the first order spatial coherence in an exciton-polariton Bose-Einstein condensate. Long-range spatial coherence is found to set in right at the onset of stimulated scattering, on a picosecond time scale. The cohe ...

Smaller Global and Regional Cortical Volume in Combat-Related Posttraumatic Stress Disorder

Marie Schaer

Context Two sets of findings predict smaller cerebral cortical gray matter volume in adult posttraumatic stress disorder (PTSD). Measures of intracranial tissue volume and cerebral tissue volume have been observed to be smaller in adolescents with maltreat ...

A model for the involvement of neural cell adhesion molecules in stress-related mood disorders

Maria del Carmen Sandi Perez, Reto Bisaz

Critical interactions between genetic and environmental factors -- among which stress is one of the most potent non-genomic factors -- are involved in the development of mood disorders. Intensive work during the past decade has led to the proposal of the n ...

Mutant huntingtin's effects on striatal gene expression in mice recapitulate changes observed in human Huntington's disease brain and do not differ with mutant huntingtin length or wild-type huntingtin dosage

Darlene Goldstein, Mauro Delorenzi, Thierry Sengstag

To test the hypotheses that mutant huntingtin protein length and wild-type huntingtin dosage have important effects on disease-related transcriptional dysfunction, we compared the changes in mRNA in seven genetic mouse models of Huntington's disease (HD) a ...

Realistic heterointerface model for excitonic states in growth-interrupted GaAs quantum wells

Vincenzo Savona

We present a model for the disorder of the heterointerfaces in GaAs quantum wells including long-range components like monolayer island formation induced by the surface diffusion during the epitaxial growth process. Taking into account both interfaces, a d ...
