Motivated by some inconsistencies in the way quantum fluctuations are included beyond the classical treatment of hard-core bosons on a lattice in the recent literature, we revisit the large-S semiclassical approach to hard-core bosons on the square lattice ...
This thesis is focused on classical and semiclassical approximations of a specific quantum time correlation function, the “quantum fidelity.” Namely, we rigorously study the efficiency of a continuous class of algorithms for the evaluation of its classical ...
Based on the CYCLONE case, simulations of collisional electrostatic ion temperature gradient (ITG) microturbulence carried out with the global gyrokinetic particle-in-cell (PIC) code ORB5 are presented. Considering adiabatic electrons, an increase in ion h ...
In a test of principle a neutron spin filter has been built, which is based on dynamic nuclear polarization (DNP) using photo-excited triplet states. This DNP method has advantages over classical concepts as the requirements for cryogenic equipment and mag ...
So far, the distributed computing community has either assumed that all the processes of a distributed system have distinct identifiers or, more rarely, that the processes are anonymous and have no identifiers. These are two extremes of the same general mo ...
Abstract of the book: While the importance of innovation to economic development is widely understood, the conditions conducive to it remain the focus of much attention. This volume offers new theoretical and empirical contributions to fundamental question ...
This paper reviews topics in price theory such as rational choice, Walrasian equilibria, complete and incomplete markets, externalities and nonmarket goods, strategic pricing with complete and incomplete information, and some behavioral anomalies. Contains ...
This article describes how prices are treated in economic theory. Section 17.2 begins by introducing the concepts of ‘rational preference’ and ‘utility function’, which are standard building blocks of models that attempt to explain choice behaviour. Sectio ...
The basic idea of the project (run in collaboration with a Swiss company) is to design a flexible winding, which will 'replace' the classical slotless BLDC motor winding. The new winding should be thermally and mechanically improved compared to the classic ...
In classical models of vision, low level visual tasks are explained by low level neural mechanisms. For example, in crowding, perception of a target is impeded by nearby elements because, as it is argued, responses of neurons coding for nearby elements are ...
