Backtracking Dynamical Cavity Method

Freya Behrens, Lenka Zdeborová, Barbora Hudcová

The cavity method is one of the cornerstones of the statistical physics of disordered systems such as spin glasses and other complex systems. It is able to analytically and asymptotically exactly describe the equilibrium properties of a broad range of mode ...

Optimization and equilibrium problems with discrete choice models

Stefano Bortolomiol

Many transportation markets are characterized by oligopolistic competition. In these markets customers, suppliers and regulators make decisions that are influenced by the preferences and the decisions of all other agents. In particular, capturing and under ...

Fabrication of micrometer-sized drops as templates for particles

Mathias Steinacher

Drops are omnipresent in our daily life for example in the form of rain drops or as oil drops in a salad dressing. On a technological basis, drops can be used to conduct chemical or biological reactions. These drops often serve as templates to produce mate ...

Goldstone equivalence and high energy electroweak physics

Andrea Wulzer, Gabriel Francisco Cuomo, Luca Vecchi

The transition between the broken and unbroken phases of massive gauge theories, namely the rearrangement of longitudinal and Goldstone degrees of freedom that occurs at high energy, is not manifestly smooth in the standard formalism. The lack of smoothnes ...

Accurate Description of Nuclear Quantum Effects with High-Order Perturbed Path Integrals (HOPPI)

Michele Ceriotti, Venkat Kapil

Imaginary time path-integral (PI) simulations that account for nuclear quantum effects (NQE) beyond the harmonic approximation are increasingly employed together with modern electronic-structure calculations. Existing PI methods are applicable to molecules ...

Kinetic approach to the Schwinger effect during inflation

Oleksandr Sobol

Using the kinetic approach, we study the impact of the charged particle dynamics due to the Schwinger effect on the electric field evolution during inflation. As a simple model of the electric field generation, we consider the kinetic coupling of the elect ...

Three Problems of Liquidity under Asymmetric Information

Sylvain Jean Pascal Carré

This thesis develops models for three problems of liquidity under asymmetric information. In the chapter "Disclosures, Rollover Risk, and Debt Runs" I build a model of dynamic debt runs without perfect information in order to understand the impact of asset ...

When droplets deform, break up and propel microswimmers

Giacomo Gallino

This thesis investigates the motion and breakup of droplets in low-Reynolds-number flows, focusing on two aspects. In the first part, we study the breakup of droplets in subcritical flow conditions, when there exists a linearly stable solution for the drop ...

Asset Pricing When 'This Time Is Different'

Pierre Collin Dufresne

Recent evidence suggests that younger people update beliefs in response to aggregate shocks more than older people. We embed this generational learning bias in an equilibrium model in which agents have recursive preferences and are uncertain about exogenou ...

Constraint-Driven Design with Combinatorial Equilibrium Modelling

Corentin Jean Dominique Fivet, Pierluigi D'Acunto

This paper presents an extension to the Combinatorial Equilibrium Modelling (CEM) design framework. So far, CEM gives the possibility to generate and explore multiple spatial equilibrium solutions in the early conceptual design phase. In addition to the fo ...

Parameter Learning in General Equilibrium: The Asset Pricing Implications

Pierre Collin Dufresne

Parameter learning strongly amplifies the impact of macroeconomic shocks on marginal utility when the representative agent has a preference for early resolution of uncertainty. This occurs as rational belief updating generates subjective long-run consumpti ...

A numerical study of droplet trapping in microfluidic devices

François Gallaire, Mathias Nagel, Pierre-Thomas Paul Brun

Microfluidic channels are powerful means of control of minute volumes such as droplets. These droplets are usually conveyed at will in an externally imposed flow which follows the geometry of the micro-channel. It has recently been pointed out by Dangla et ...

Monte Carlo evaluation of the equilibrium isotope effects using the Takahashi-Imada factorization of the Feynman path integral

Jiri Vanicek, Marcin Rafal Buchowiecki

The Feynman path integral approach for computing equilibrium isotope effects and isotope fractionation corrects the approximations made in standard methods, although at significantly increased computational cost. We describe an accelerated path integral ap ...

Bayesian demand calibration for dynamic traffic simulations

Michel Bierlaire, Gunnar Flötteröd

We present an operational framework for the calibration of demand models for dynamic traffic simulations, where calibration refers to the estimation of a structurally predefined model's parameters from real data. Our focus is on disaggregate simulators tha ...

A Metamodel of the Oil Game under Climate Treaties

Alain Haurie, Marc Vielle

A climate treaty like the one which should replace the Kyoto Protocol after 2012, may have important impacts on the oil, gas and coal markets. The full impact of such a treaty will not be felt before 2030. In this paper one uses a computable general equili ...

Evolution of Langmuir Film of Nanoparticles Through Successive Compression Cycles

Francesco Stellacci, Jiwon Kim

The success of nanoparticle-based devices will need reliable fabrication methods for well-defined, defect-free self-assembled structures of nanoparticles (NPs). NP self-assembly is a process governed by an interplay between many inter-particle interactions ...

A game of international climate policy solved by a homogeneous oracle-based method for variational inequalities

Alain Haurie, Marc Vielle

This paper presents a game-theoretic model for the international negotiations that should take place to renew or extend the Kyoto protocol beyond 2012. These negotiations should lead to a self-enforcing agreement on a burden sharing scheme to realize the n ...

On the effects of the equilibrium model in gyrokinetic simulatins: From s-alpha to diverted MHD equilibrium

Olivier Sauter, Emiliano Fable, Alice Burckel, Xavier Lapillonne

In order to better identify the role of the magnetic topology on ITG and TEM instabilities, different MHD equilibria with increasing complexity are calculated using the CHEASE code [1]. We start from the geometry of the s-alpha cyclone benchmark case [2], ...
