Disorder instability of the magnon condensate in a frustrated spin ladder [PDF]
, 2011 The effect of disorder is studied on the field-induced quantum phase transition in the frustrated spin-ladder compound H8C4SO2Cu2(Cl[1-x]Brx)4 using bulk magnetic and thermodynamic measurements. The parent material (x=0) is a quantum spin liquid, which in applied fields is known to form a magnon condensate with long-range helimagnetic order.

Diffusion and transport in locally disordered driven lattices [PDF]
, 2016 We study the effect of disorder on the particle density evolution in a classical Hamiltonian driven lattice setup. If the disorder is localized within a finite sub-domain of the lattice, the emergence of strong tails in the density distribution which even increases towards larger positions is shown, thus yielding a highly non Gaussian particle density ...

Recoverable Robust Representatives Selection Problems with Discrete Budgeted Uncertainty [PDF]
arXiv, 2020 Recoverable robust optimization is a multi-stage approach, where it is possible to adjust a first-stage solution after the uncertain cost scenario is revealed. We analyze this approach for a class of selection problems. The aim is to choose a fixed number of items from several disjoint sets, such that the worst-case costs after taking a recovery action

Pulse Propagation in Resonant Tunneling II [PDF]
arXiv, 2005 We consider the analytically solvable model of a Gaussian pulse tunneling through a transmission resonance with a general Fano characteristic. It is demonstrated that the transmitted pulse contains enough information to determine uniquely all parameters defining the Fano resonance. This is in contrast to the measurement of the static conductance.

Some Toric Manifolds and a Path Integral [PDF]
Progress in Math. 231, The Orbit Method in Geometry and Physics.
In Honor of A.A.Kirillov., Birkhauser, 2003, 395-419, 2003 The toric manifolds in question were invented by Bott and studied by Grossberg and Karshon under the name "Bott towers". Interest in them comes from their relation to characters of semisimple Lie groups and geometric quantization. We offer another construction of them, introduce a family symplectic structures as curvatures of line bundles, work out ...

Quantum scaling in nano-transistors [PDF]
arXiv, 2008 In our previous papers on ballistic quantum transport in nano-transistors [J. Appl. Phys. 98, 84308 (2005)] it was demonstrated that under certain conditions it is possible to reduce the three-dimensional transport problem to an effectively one-dimensional one.

Real-time Prediction of Intermediate-Horizon Automotive Collision Risk [PDF]
arXiv, 2018 Advanced collision avoidance and driver hand-off systems can benefit from the ability to accurately predict, in real time, the probability a vehicle will be involved in a collision within an intermediate horizon of 10 to 20 seconds. The rarity of collisions in real-world data poses a significant challenge to developing this capability because, as we ...

Utilizing Large Language Models for Automating Technical Customer Support [PDF]
arXivThe use of large language models (LLMs) such as OpenAI's GPT-4 in technical customer support (TCS) has the potential to revolutionize this area. This study examines automated text correction, summarization of customer inquiries and question answering using LLMs. Through prototypes and data analyses, the potential and challenges of integrating LLMs into

Statistical Modelling of Driving Scenarios in Road Traffic using Fleet Data of Production Vehicles [PDF]
arXivEnsuring the safety of road vehicles at an acceptable level requires the absence of any unreasonable risk arising from all potential hazards linked to the intended au-tomated driving function and its implementation. The assurance that there are no unreasonable risks stemming from hazardous behaviours associated to functional insufficiencies is denoted ...
