description: We discuss the production of radiation and dark matter assuming a time-dependent inflaton decay rate during the reheating period. It is shown that the time dependence of the inflaton decay rate can substantially modify the reheating dynamics. As an illustration, a leading interaction between the inflaton $ϕ$ and the Higgs doublet ${\boldsymbol h}$ of the form $ϕ|{\boldsymbol h}|^2$ was adopted. In the presence of such interaction, the Higgs doublet acquires a $ϕ$-dependent mass which generates vacuum-expectation-value due to inflaton oscillations and breaks the Standard Model gauge symmetry. This leads to a time-dependent inflaton decay rate during the reheating period, and consequently, the production of radiation and dark matter during this period is modified. Regions of the parameter space that describe the observed value of the dark matter abundance were found and compared with the standard case when inflaton the decay rate is constant.

Management Effects on Biodiversity and Pollination Services in a Suburban Landscape
Creators: name: Hosler, Sheryl C
Publisher: name: University of Illinois at Chicago

description: Previous research has indicated that urban and suburban areas may provide quality habitat for bees and support pollination services. However, the mechanisms determining the suitability of urban environments as bee habitat are still largely unknown. I conducted a series of field studies in the Chicago area to determine the effects of the suburban environment on bee biodiversity and pollination services. Sampling was done in residential backyards and gardens as well as in powerline corridors (the strips of land under high-voltage powerlines and towers). I conducted visual surveys of floral resources and sampled the bee community using both timed visual observations and pan trapping. I also conducted two sentinel plant assays (using cucumber, Cucumis sativus, and a native annual, Bidens aristosa) to monitor pollination services in my study sites. I found that beta diversity for both floral resources and bees was higher in residential neighborhoods than in powerline corridors, most likely due to the resource and management heterogeneity of neighborhoods managed by many small-scale decision makers. I also found that cucumber seed set increased with increasing bee community functional evenness, suggesting that sites with more even representation of many bee functional trait values have higher pollination activity than sites dominated by a few trait values. Finally, I utilized a structural equation model to illustrate the direct and indirect relationships between pollination, bees, floral resources, and management in my sites. I found that floral functional divergence directly affected both bees and pollination. The combined results of this dissertation indicate that powerline corridors and suburban residential neighborhoods provide opportunities for biodiversity conservation and support a vital ecosystem function, but that these opportunities are heavily dependent on site management type. Future research should focus on determining causal relationships between suburban site characteristics and both the bee community and pollination services.

description: We study the influence of a linear energy bias on a non-equilibrium excitation on a chain of molecules coupled to local phonons (a tilted Holstein model) using both a random-walk rate kernel theory and a nonperturbative, massively parallelized adaptive-basis algorithm. We uncover structured and discrete vibronic resonance behavior fundamentally different from both linear response theory and homogeneous polaron dynamics. Remarkably, resonance between the phonon energy $\hbarω$ and the bias $δ_ε$ occurs not only at integer but also fractional ratios $δ_ε/(\hbarω) = \frac{m}{n}$, which effect long-range $n$-bond $m$-phonon tunneling. These observations are also reproduced in a model calculation of a recently demonstrated Cy3 system. Potential applications range from molecular electronics to optical lattices and artificial light harvesting via vibronic engineering of coherent quantum transport.

description: We develop formalisms for a network of vector sensors, sensitive to certain spatial components of the signals, to identify the properties of a light axion or a dark photon background. These bosonic fields contribute to vector-like signals in the detectors, including effective magnetic fields triggering the spin precession, effective electric currents in a shielded room, and forces on the matter. The interplay between a pair of vector sensors and a baseline that separates them can potentially uncover rich information of the bosons, including angular distribution, polarization modes, source localization, and macroscopic circular polarization. Using such a network, one can identify the microscopic nature of a potential signal, such as distinguishing between the axion-fermion coupling and the dipole couplings with the dark photon.

description: We explore a new mechanism for reproducing the Dark Matter (DM) abundance: scatterings of one DM particle on light Standard Model particles. Strong bounds on its decays can be satisfied if DM undergoes freeze-in and has a mass around or below the pion mass. This happens, for example, in theories with a right-handed neutrino interacting with charged fermions through a leptoquark exchange. These leptoquarks can be linked to the ones motivated by the B-physics anomalies if assumptions about the flavour structure are made. DM signals are unusual, with interesting possibilities for direct and indirect detection. Achieving thermal freeze-out instead requires models with more than one DM flavour, and couplings parametrically smaller than what needed by the usual pair annihilations.

description: In the contemporary era, many organizations and companies are confronted with a signif-icant surge in data volumes. This has led to the challenge of capturing, storing, managing, and analyzing terabytes of data, which are stored in diverse formats and originate from numerous internal and external sources. Furthermore, the emergence of novel applica-tions, such as trading, and artificial intelligence, has made the processing of vast amounts of data in real time an absolute necessity. These requirements exceed the processing ca-pacity of traditional on-disk database management systems, which are ill-equipped to manage this data and to provide real-time results. Therefore, data management requires new solutions to cope with the challenges of data volumes and processing data in real time. An in-memory database system (IMDB- or IMD system) is a database management system that is emerging as a solution to these challenges, with the support of other tech-nologies. IMDBs are capable of processing massive data distinctly faster than traditional database management systems. This work examines the approach of IMDBs, with a par-ticular focus on SAP HANA, and compares it with other IMDBs.

description: Heralded entanglement between distant quantum memories is the key resource for quantum networks. Based on quantum repeater protocols, these networks will facilitate efficient large-scale quantum communication and distributed quantum computing. However, despite vast efforts, long-distance fibre based network links have not been realized yet. Here we present results demonstrating heralded entanglement between two independent, remote single-atom quantum memories generated over fibre links with a total length up to 33 km. To overcome the attenuation losses in the long optical fibres of photons initially emitted by the Rubidium quantum memories, we employ polarization-preserving quantum frequency conversion to the low loss telecom band. The presented work represents a milestone towards the realization of efficient quantum network links.

Reward-Driven Group Fairness in Machine Learning

description: This thesis addresses fundamental challenges and underlying assumptions associated with group fairness definitions in machine learning, striving to develop more effective strategies for both defining group fairness and identifying fair policies.

To start, we identify four problematic assumptions with existing group fairness definitions: fair predictions guarantee fair outcomes, predictions are independent of target variables, predicting an unobserved target is the objective, and decisions for one individual do not impact others. To tackle these issues, we define a utility-based group fairness framework, grounded in the principles of individual utility and counterfactual outcomes. The framework enables standard group fairness definitions to naturally extend to various ML environments, including classification, clustering, and reinforcement learning (RL). We evaluate our approach on real-world public datasets, including the German credit dataset and 2020 US Census Bureau CVAP data.

We further delve into achieving group fairness specifically in RL, extending the exploration beyond classification. We emphasize the distinction between decision-maker utility and individual utility, the latter often ignored in existing policy-learning techniques. We also explore solutions to improve on the concept of "no-harm", so that policies do not inadvertently harm people in their attempt to be "fair". To achieve these, we propose a multi-objective reward function that directly optimizes decision-maker utility, individual utility improvement, and individual utility equality. Illustrated in a simulated sequential loan application environment modeled as an MDP, we benchmark our approach against state-of-the-art methods, underscoring its effectiveness on decision-making applications.

Last, we address the challenge of defining fairness in new domains where fairness has not yet been agreed upon. Our research introduces a novel method for learning and applying group fairness preferences across different classification domains, without the need for manual fine-tuning. Utilizing concepts from inverse reinforcement learning (IRL), our approach enables the extraction and application of fairness preferences from human experts or established algorithms. We propose the first technique for using IRL to recover and adapt group fairness preferences to new domains, offering a low-touch solution for implementing fair classifiers in settings where expert-established fairness tradeoffs are not yet defined.

description: Thanks to new digital technologies, web users are continuously targeted by offers that potentially fit their interests even if they are not actively looking for a product. Does this matching always promote transactions with high social value? We consider a model in which web users with state-contingent preferences are targeted by relevant banners. We characterize the optimal strategy of a seller who, in addition to the price of the offered good, designs a banner. We show that, in equilibrium, there is a positive relationship between the price of the offered good and the accuracy of the banner sent to users. Then, we consider the strategic decision of a Platform that attracts sellers because of its targeting abilities and we underline that a reduction in seller's costs may
translate into less informative banners and lower prices, fueling purchases of goods that rational individuals may regret due to the persuasive nature of banners.

description: Quantum interference effects in the unmodulated quantum systems with light-matter interaction have been widely studied, such as electromagnetically induced transparency (EIT) and Autler-Townes splitting (ATS). However, the similar quantum interference effects in the Floquet systems (i.e., periodically modulated systems), which might cover rich new physics, were rarely studied. In this article, we investigate the quantum interference effects in the Floquet two- and three-level systems analytically and numerically. We show a coherent destruction tunneling effect in a lotuslike multipeak spectrum with a Floquet two-level system, where the intensity of the probe field is periodically modulated with a square-wave sequence. We demonstrate that the multipeak split into multiple transparency windows with tunable quantum interference if the Floquet system is asynchronously controlled via a third level. Based on phenomenological analysis with Akaike information criterion, we show that the symmetric central transparency window has a similar mechanism to the traditional ATS or EIT depending on the choice of parameters, additional with an extra degree of freedom to control the quantum interference provided by the modulation period. The other transparent windows are shown to be asymmetric, different from the traditional ATS and EIT windows. These nontrivial quantum interference effects open up a scope to explore the applications of the Floquet systems.

description: Despite their development for over a decade, a key problem blockchains are still facing is scalability in terms of throughput, typically limited to a few transactions per second. A fundamental factor limiting this metric is the propagation latency of blocks through the underlying peer-to-peer network, which is typically constructed by means of random connectivity. Disseminating blocks fast improves not only the transaction throughput, but also the security of the system as it reduces the probability of forks. In this paper we present CougaR: a simple yet efficient, eclipse-resistant, decentralized protocol that substantially reduces the block dissemination time in blockchain networks. CougaR's key advantages stem from its link selection policy, which combines a network latency criterion with randomness to offer fast and reliable block dissemination to the entire network. Moreover, CougaR is eclipse-resistant by design, as nodes are protected from having all their links directly or indirectly imposed on them by others, which is the typical vulnerability exploited to deploy eclipse attacks. We rigorously evaluate CougaR by an extensive set of experiments, both against a wide spectrum of parameter settings, and in comparison to the current state of the art.

description: We employ Reactive Dynamical Density Functional Theory (R-DDFT) and Reactive Brownian Dynamics (R-BD) simulations to investigate the dynamics of a suspension of active soft Gaussian colloids with binary interaction switching, i.e., a one-component colloidal system in which every particle stochastically switches at predefined rates between two interaction states with different mobility. Using R-DDFT we extend a theory previously developed to access the dynamics of inhomogeneous liquids to study the influence of the switching activity on the self and distinct part of the Van Hove function in bulk solution, and determine the corresponding mean squared displacement of the switching particles. Our results demonstrate that, even though the average diffusion coefficient is not affected by the switching activity, it significantly modifies the non-equilibrium dynamics and diffusion coefficients of the individual particles, leading to a crossover from short to long times, with a regime for intermediate times showing anomalous diffusion. In addition, the self-part of the van Hove function has a Gaussian form at short and long times, but becomes non-Gaussian at intermediates ones, having a crossover between short and large displacements. The corresponding self-intermediate scattering function shows the two-step relaxation patters typically observed in soft materials with heterogeneous dynamics such as glasses and gels. We also introduce a phenomenological Continuous Time Random Walk (CTRW) theory to understand the heterogeneous diffusion of this system. R-DDFT results are in excellent agreement with R-BD simulations and the analytical predictions of CTRW theory, thus confirming that R-DDFT constitutes a powerful method to investigate not only the structure and phase behavior, but also the dynamical properties of non-equilibrium active switching colloidal suspensions.
