Variational quantum time evolution without the quantum geometric tensor

Giuseppe Carleo, Jannes Willy E. Nys, Riccardo Rossi, Julien Sebastian Gacon

Realand imaginary -time quantum state evolutions are crucial in physics and chemistry for exploring quantum dynamics, preparing ground states, and computing thermodynamic observables. On near -term devices, variational quantum time evolution is a promising ...

Stability of a liquid layer draining around a horizontal cylinder: Interplay of capillary and gravity forces

François Gallaire, Shahab Eghbali, Simeon Vladimirov Djambov

We study the drainage of a viscous liquid film coating the outside of a solid horizontal cylinder, where gravity acts vertically. We focus on the limit of large Ohnesorge numbers Oh, where inertia is negligible compared to viscous effects. We first study t ...

WikiArtVectors: Style and Color Representations of Artworks for Cultural Analysis via Information Theoretic Measures

Bhargav Srinivasa Desikan

With the increase in massive digitized datasets of cultural artefacts, social and cultural scientists have an unprecedented opportunity for the discovery and expansion of cultural theory. The WikiArt dataset is one such example, with over 250,000 high qual ...

Development of C-C and C-O bond cleavage catalysts for the depolymerization of plastics

Wei-Tse Lee

Chemical recycling of plastics provides more flexibility for materials circulation than landfill disposal or incineration. Intensive research efforts have been devoted to maximizing the efficiency of chemical recycling through catalyst development. The fro ...

Exploiting Marginal Stability in Slow-Fast Quasilinear Dynamical Systems

Alessia Ferraro

The accurate investigation of many geophysical phenomena via direct numerical simulations is computationally not possible nowadays due to the huge range of spatial and temporal scales to be resolved. Therefore advances in this field rely on the development ...

Multi-layer State Evolution Under Random Convolutional Design

Lenka Zdeborová, Florent Gérard Krzakala

Signal recovery under generative neural network priors has emerged as a promising direction in statistical inference and computational imaging. Theoretical analysis of reconstruction algorithms under generative priors is, however, challenging. For generati ...

Arnoldi-Lindblad time evolution: Faster-than-the-clock algorithm for the spectrum of time-independent and Floquet open quantum systems

Fabrizio Minganti

The characterization of open quantum systems is a central and recurring problem for the development of quantum technologies. For time-independent systems, an (often unique) steady state describes the average physics once all the transient processes have fa ...

Stabilization of cultural innovations depends on population density: Testing an epidemiological model of cultural evolution against a global dataset of rock art sites and climate-based estimates of ancient population densities

Francesco Casalegno, Taylor Howard Newton

Demographic models of human cultural evolution have high explanatory potential but weak empirical support. Here we use a global dataset of rock art sites and climate and genetics-based estimates of ancient population densities to test a new model based on ...

A Third Way Alternative; Critical Assessments from the Model of the Yugoslav City

Jana Konstantinova

This dissertation aims to demonstrate the development, meaning and significance of cultural infrastructure in the cities of Skopje, Belgrade and Sarajevo (1945-1991). In the historic context, culture became the fundamental critical tool with which to yield ...

Generation of chiral asymmetry via helical magnetic fields

Salim Bennouna

It is well known that helical magnetic fields undergo a so-called inverse cascade by which their correlation length grows due to the conservation of magnetic helicity in classical ideal magnetohydro-dynamics (MHD). At high energies above approximately 10 M ...

Entrepreneurship across Sociocultural Contexts: Empirical and Theoretical Perspectives

Shirah Eden Foy

Entrepreneurship is a highly contextualized process. Yet, the vast majority of entrepreneurship research has focused on Western contexts, yielding a skewed picture of global entrepreneurial behavior. Moreover, theories of mainstream psychology explaining t ...

The potential of textile reinforced concrete for design of innovative structures

Aurelio Muttoni, Miguel Fernández Ruiz, Patricia Guaita, Raffael Baur, Patrick Lorenzo Valeri

Textile Reinforced Concrete (TRC) is a recent evolution of ordinary reinforced concrete. This relatively new construction material replaces steel reinforcement with high-strength, non-corrosive textile fabrics in order to reduce cover requirements to minim ...

Sexual conflict drives male manipulation of female postmating responses in Drosophila melanogaster

Laurent Keller, Brian Dennis Hollis

In many animals, females respond to mating with changes in physiology and behavior that are triggered by molecules transferred by males during mating. In Drosophila melanogaster, proteins in the seminal fluid are responsible for important female postmating ...

Implementing bikesharing systems in small cities: Evidence from the Swiss experience

Vincent Kaufmann, Emmanuel Pierre Jean Ravalet, Ander Audikana Arriola, Virginie Andréa Baranger

Research on bikesharing has largely focused on systems operating in large cities. Based on the Swiss experience, this paper explores the challenges that small cities (

X-Point Effect on Plasma Blob Dynamics

Ambrogio Fasoli, Ivo Furno, Paolo Ricci, Christian Gabriel Theiler, Fabio Avino

Plasma blob dynamics on the high-field side in the proximity of a magnetic field null (X point) is investigated in TORPEX. A significant acceleration of the blobs towards the X point is observed. Close to the X point the blobs break apart. The E x B drifts ...

Modeling Flow Pattern and Evolution of Meandering Channels with a Nonlinear Model

Koen Blanckaert

Meander dynamics has been the focus of river engineering for decades; however, it remains a challenge for researchers to precisely replicate natural evolution processes of meandering channels with numerical models due to the high nonlinearity of the govern ...

Start-up scenario studies in gyrotron oscillator using a novel linear and spectral code

Stefano Alberti, Minh Quang Tran, Jean-Philippe Hogge, Jérémy Genoud, Trach-Minh Tran

A linear and spectral model has recently been developed [1], describing the self-consistent wave-particle interaction in a gyrotron oscillator. The spectral approach, compared to commonly used time-evolution approaches, has the possibility to describe all ...

Evolution and selection of river networks: Statics, dynamics, and complexity

Andrea Rinaldo, Amos Maritan

Moving from the exact result that drainage network configurations minimizing total energy dissipation are stationary solutions of the general equation describing landscape evolution, we review the static properties and the dynamic origins of the scale-inva ...

Selection methods regulate evolution of cooperation in digital evolution

Dario Floreano, Laurent Keller, Pawel Lichocki

A key, yet often neglected, component of digital evolution and evolutionary models is the 'selection method' which assigns fitness (number of offspring) to individuals based on their performance scores (efficiency in performing tasks). Here, we study with ...
