Dense Coding with Locality Restriction for Decoder: Quantum Encoders vs. Super-Quantum Encoders
Creators: name: Hayashi, Masahito
name: Wang, Kun
Publisher: name: arXiv
Year: 2021
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: We investigate dense coding by imposing various locality restrictions to our decoder by employing the resource theory of asymmetry framework. In this task, the sender Alice and the receiver Bob share an entangled state. She encodes the classical information into it using a symmetric preserving encoder and sends the encoded state to Bob through a noiseless quantum channel. The decoder is limited to a measurement to satisfy a certain locality condition on the bipartite system composed of the receiving system and the preshared entanglement half. Our contributions are summarized as follows: First, we derive an achievable transmission rate for this task dependently of conditions of encoder and decoder. Surprisingly, we show that the obtained rate cannot be improved even when the decoder is relaxed to local measurements, two-way LOCCs, separable measurements, or partial transpose positive (PPT) measurements for the bipartite system. Moreover, depending on the class of allowed measurements with a locality condition, we relax the class of encoding operations to super-quantum encoders in the framework of general probability theory (GPT). That is, when our decoder is restricted to a separable measurement, theoretically, a positive operation is allowed as an encoding operation. Surprisingly, even under this type of super-quantum relaxation, the transmission rate cannot be improved. This fact highlights the universal validity of our analysis beyond quantum theory.

Analytical Solution for the Anisotropic Rabi Model: Effects of Counter-Rotating Terms
Creators: name: Zhang, Guofeng
name: Zhu, Hanjie
Publisher: name: arXiv
Year: 2015
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: The anisotropic Rabi model, which was proposed recently, differs from the original Rabi model: the rotating and counter-rotating terms are governed by two different coupling constants. This feature allows us to vary the counter-rotating interaction independently and explore the effects of it on some quantum properties. In this paper, we eliminate the counter-rotating terms approximately and obtain the analytical energy spectrums and wavefunctions. These analytical results agree well with the numerical calculations in a wide range of the parameters including the ultrastrong coupling regime. In the weak counter-rotating coupling limit we find out that the counter-rotating terms can be considered as the shifts to the parameters of the Jaynes-Cummings model. This modification shows the validness of the rotating-wave approximation on the assumption of near-resonance and relatively weak coupling. Moreover, the analytical expressions of several physics quantities are also derived, and the results show the break-down of the U(1)-symmetry and the deviation from the Jaynes-Cummings model.

Conditions for the development of online teaching capacity: A case study
Creators: name: Da Rosa Dos Santos, Luciano
Publisher: name: ETH Learning and Teaching Journal
Year: 2020

description: Online learning has shown its potential for more than three decades in postsecondary institutions. However, for online learning to be implemented appropriately, a key aspect is proper development of faculty members who are going to facilitate online courses. This paper describes an instrumental case study investigating the conditions for the development of online teaching capacity of faculty members in a professional Faculty in Canada. Personal commitment, support systems and leadership were found to be key factors influencing the capacity-building process. Understanding such conditions can help institutions design educational development strategies that better align with the needs of faculty members.

High spatial resolution and three-dimensional measurement of charge density and electric field in nanoscale materials using off-axis electron holography
Creators: name: Zheng, Fengshan
Publisher: name: Zenodo
Year: 2020
Subjects: Charge density, electric field, transmission electron microscopy, electron holography

description: The ability to make local measurements of charge density in nanoscale materials and devices is essential for understanding many material properties. The charge density can then be used to infer the electric field or electrostatic potential within and around the specimen. This information is important for scientists working on subjects such as field electron emission and atom probe tomography. Off-axis electron holography is a powerful technique that can be used to record the phase shift of a high-energy electron wave travelling through an electron-transparent specimen in a transmission electron microscope. Information about the charge density within the specimen can be retrieved from the measured phase with high spatial resolution. In this thesis, charge density and electric field measurements are performed, both in projection and in three dimensions, with a primary focus on samples that have a needle-shaped geometry. Three approaches are used: an analytical model-dependent approach, a model-independent approach and an approach based on numerical model-based iterative reconstruction. The model-based iterative approach allows a priori information, such as the shape of the object and the influence of charges that are located outside the field of view, to be taken into account. More importantly, it also allows for the reconstruction of three-dimensional charge density distributions from incomplete tomographic tilt of phase images without the artefacts that would be present if conventional tomographic reconstruction algorithms were used. In this thesis, a W5O14 nanowire is investigated experimentally in the presence of an applied electrical bias and the charge distribution along it is evaluated. A carbon fibre needle-shaped specimen is then studied, in order to demonstrate the capability of the model- based iterative approach to measure the three-dimensional charge density, electric field and electrostatic potential both inside and around it. Finally, a systematic investigation of electron-beam-induced charging in a needle-shaped specimen with an insulating Al2O3 apex is presented, including the dependence of the results on electron dose rate, total dose, temperature, primary electron energy and the surface state of the sample. Great care is required with the acquisition and interpretation of the results, in particular because charging phenomena are sensitive to the electrical conductivity of the sample, the presence of contact potentials and the presence of (unknown) surface states.

Predicting volatility: getting the most out of return data sampled at different frequencies
Creators: name: Valkanov, Rossen
name: Ghysels, Eric
name: Santa-Clara, Pedro
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2006

description: We consider various mixed data sampling (MIDAS) regressions to predict volatility. The regressions differ in the specification of regressors (squared returns, absolute returns, realized volatility, realized power, and return ranges), in the use of daily or intra-daily (5-min) data, and in the length of the past history included in the forecasts. The MIDAS framework allows us to compare regressions across all these dimensions in a very tightly parameterized fashion. Using equity return data, we find that daily realized power (involving 5-min absolute returns) is the best predictor of future volatility (measured by increments in quadratic variation) and outperforms models based on realized volatility (i.e. past increments in quadratic variation). Surprisingly, the direct use of high-frequency (5 min) data does not improve volatility predictions. Finally, daily lags of 1–2 months are sufficient to capture the persistence in volatility. These findings hold both in- and out-of-sample.

description: Influence of disorder-induced Anderson localization and of electron-electron interaction on superconductivity in two-dimensional systems is explored. We determine the superconducting transition temperature $T_c$, the temperature dependence of the resistivity, the phase diagram, as well as the magnetoresistance. The analysis is based on the renormalization group (RG) for a nonlinear sigma model. Derived RG equations are valid to the lowest order in disorder but for arbitrary electron-electron interaction strength in particle-hole and Cooper channels. Systems with preserved and broken spin-rotational symmetry are considered, both with short-range and with long-range (Coulomb) interaction. In the cases of short-range interaction, we identify parameter regions where the superconductivity is enhanced by localization effects. Our RG analysis indicates that the superconductor-insulator transition is controlled by a fixed point with a resistivity $R_c$ of the order of the quantum resistance $R_q = h/ 4e^2$. When a transverse magnetic field is applied, we find a strong nonmonotonous magnetoresistance for temperatures below $T_c$.

description: A finite strain nonlinear constitutive model is presented to study the extreme mechanical behavior of a polyurethane-urea well suited for many engineering applications. The micromechanically- and thermodynamically based constitutive model captures salient features in resilience and dissipation in the material at low to high strain rate. The extreme deformation features are further elucidated by laser-induced micro-particle impact tests for the material, where an ultrafast strain rate ($>10^6$ s$^{-1}$) incurs. Numerical simulations for the strongly inhomogeneous deformation events are in good agreement with the experimental data, supporting the predictive capabilities of the constitutive model for the extreme deformation features of the PUU material over at least 9 orders of magnitude in strain rates ($10^{-3}$ to $10^{6}$ s$^{-1}$).

description: Predicting magic wavelengths accurately requires precise knowledge of electric-dipole matrix elements of nearby atomic transitions. As a result, measurements of magic wavelengths allow us to test theoretical predictions for the matrix elements that frequently can not be probed by any other methods. Here, we calculate and measure a magic wavelength near $473$ nm of the $5s^2\,^1\!S_0 - 5s5p\,^3\!P_1$ intercombination transition of ${}^{88}$Sr. Experimentally, we find $473.361(4)$ nm for $Δm=0$ ($π$ transition) and $473.133(14)$ nm for $Δm=-1$ ($σ^{-}$ transition). Theoretical calculations yield $473.375(22)$~nm and $473.145(20)$ nm, respectively. The $^3\!P_1$ polarizability is dominated by the contributions to the $5p^2\, ^3\!P$ levels and excellent agreement of theory and experiment validates both theoretical values of these matrix elements and estimates of their uncertainties.
A component model for dynamic correlations

Publisher: name: The University of North Carolina at Chapel Hill University Libraries

description: The idea of component models for volatility is extended to dynamic correlations. We propose a model of dynamic correlations with a short- and long-run component specification. We call this class of models DCC-MIDAS as the key ingredients are a combination of the Engle (2002) DCC model, the Engle and Lee (1999) component GARCH model to replace the original DCC dynamics with a component specification and the Engle, Ghysels, and Sohn (2006) GARCH-MIDAS component specification that allows us to extract a long-run correlation component via mixed data sampling. We provide a comprehensive econometric analysis of the new class of models, including conditions for positive semi-definiteness, and provide extensive empirical evidence that supports the model specification.

Exploring the drivers and barriers to teaching excellence

description: In a sector that aspires to teaching excellence it is important to stand back and ask: what do we mean by this? While existing research defines effective methods for teaching and supporting learners, each institution and student collective has its own identity, culture, preferences and norms. The very exercise of locating excellence is also a powerful practice based conversation starter, particularly in terms of what makes our teaching practice “future- ready”. Findings from such evaluative conversations can provide a mandate for the advocacy of one practice over another; help individual staff develop confidence in their methods through affirmation; and shed light on institution specific conceptions of excellence.

description: We determine conditions on the filling of electrons in a crystalline lattice to obtain the equivalent of a band insulator -- a gapped insulator with neither symmetry breaking nor fractionalized excitations. We allow for strong interactions, which precludes a free particle description. Previous approaches that extend the Lieb-Schultz-Mattis argument invoked spin conservation in an essential way, and cannot be applied to the physically interesting case of spin-orbit coupled systems. Here we introduce two approaches, the first an entanglement based scheme, while the second studies the system on an appropriate flat `Bieberbach' manifold to obtain the filling conditions for all 230 space groups. These approaches only assume time reversal rather than spin rotation invariance. The results depend crucially on whether the crystal symmetry is symmorphic. Our results clarify when one may infer the existence of an exotic ground state based on the absence of order, and we point out applications to experimentally realized materials. Extensions to new situations involving purely spin models are also mentioned.

A new method of projection-based inference in GMM with weakly identified nuisance parameters
Creators: name: Zivot, Eric
name: Chaudhuri, Saraswata
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2011

description: Projection-based methods of inference on subsets of parameters are useful for obtaining tests that do not over-reject the true parameter values. However, they are also often criticized for being conservative. We show that the usual method of projection can be modified to obtain tests that are as powerful as the conventional tests for subsets of parameters. Like the usual projection-based methods, one can always put an upper bound to the rate at which the new method over-rejects the true value of the parameters of interest. The new method is described in the context of GMM with possibly weakly identified parameters.

description: Density-functional calculations are used to verify the atomic structure of the hexagonal In/Si(111)-($\sqrt{7}\times\sqrt{3}$) surface, which has been considered to represent an ultimate two-dimensional (2D) limit of metallic In overlayers. Contrary to the prevailing assumption, this surface consists of not a single layer but a double layer of In atoms, which corresponds to a hexagonal deformation of the well-established $rectangular$ In double layer formed on Si(111)-($\sqrt{7}\times\sqrt{3}$) [Park $et$ $al$., Phys. Rev. Lett. 109, 166102 (2012)]. The same double-layer thickness accounts well for the typical coexistence of the hexagonal and rectangular phases and their similar 2D electronic structures. It is thus conclusive that, regardless of rectangular or hexagonal, the In/Si(111)-($\sqrt{7}\times\sqrt{3}$) surface does not represent an one-atom-thick In overlayer.

Causality effects in return volatility measures with random times
Creators: name: Renault, Eric
name: Werker, Bas J.M.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2011

description: We provide a structural approach to identify instantaneous causality effects between quote-to-quote durations and stock price volatility. So far, in the literature, instantaneous causality effects have either been excluded or cannot be identified separately from Granger type causality effects. By giving explicit moment conditions for observed returns over (random) duration intervals, we are able to identify an instantaneous causality effect, e.g., due to news events driving both surprises in durations and surprises in volatilities. We conclude that instantaneous volatility forecasts for, e.g., IBM stock returns must be decreased by as much as 40% when not having seen the next quote before its (conditionally) median time. For less liquidly traded stocks at NYSE this effect is even stronger. Also, instantaneous volatilities are found to be much higher than indicated by standard volatility assessment procedures. Finally, the documented causality effect has significant impact on statistical inference for tick-by-tick data.

description: This paper proposes a method to design network-aware flexibility requests for local flexibility markets. These markets are becoming increasingly important for distribution system operators (DSOs) to ensure grid safety while minimizing costs and public opposition to new network investments. Despite extended recent literature on local flexibility markets, little attention has been paid to quantifying the flexibility required at each location, considering physical network constraints (e.g. line and voltage limits). The method introduced uses a chance-constrained optimization model and a LinDistFlow approximation to consider both physical network constraints and uncertainty caused by renewable production or demand fluctuations. Unlike other methods, it avoids sharing sensitive grid data with the market operator. We compare our approach against a stochastic market-clearing mechanism which serves as a benchmark, and we derive analytical conditions for the performance of our method to determine flexibility requests. We show on two case studies that our method outperforms the stochastic market-clearing benchmark in terms of computation time while achieving comparable social welfare and costs for the DSOs. One of the case studies is conducted on an actual German distribution grid, showing that the proposed method can scale well to real-sized networks.

description: In directional statistics, the von Mises distribution is a key element in the analysis of circular data. While there is a general agreement regarding the estimation of its location parameter $μ$, several methods have been proposed to estimate the concentration parameter $κ$. We here provide a thorough evaluation of the behavior of 12 such estimators for datasets of size $N$ ranging from 2 to 8\,192 generated with a $κ$ ranging from 0 to 100. We provide detailed results as well as a global analysis of the results, showing that (1) for a given $κ$, most estimators have behaviors that are very similar for large datasets ($N \geq 16$) and more variable for small datasets, and (2) for a given estimator, results are very similar if we consider the mean absolute error for $κ\leq 1$ and the mean relative absolute error for $κ\geq 1$.

Are there common values in first-price auctions? A tail-index nonparametric test
Creators: name: Hill, Jonathan B.
name: Shneyerov, Artyom
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2013

description: We develop a consistent nonparametric test of common values in first-price auctions and apply it to British Columbia Timber Sales data. The test is based on the behavior of the CDF of bids near the reserve price. We show that the curvature of the CDF is drastically different under private values (PV) and common values (CV). We then show that the problem of discriminating between PV and CV is equivalent to estimating the lower tail index of the bid distribution. Our approach admits unobserved auction heterogeneity of an arbitrary form. We develop a Hill (1975)-type tail index estimator and find presence of common values in BC Timber Sales.

description: Following Cayley, MacMahon, and Sylvester, define a non-unitary partition to be an integer partition with no part equal to one, and let $ν(n)$ denote the number of non-unitary partitions of size $n$. In a 2021 paper, the sixth author proved a formula to compute $p(n)$ by enumerating only non-unitary partitions of size $n$, and recorded a number of conjectures regarding the growth of $ν(n)$ as $n\to \infty$. Here we refine and prove some of these conjectures. For example, we prove $p(n) \sim ν(n)\sqrt{n/ζ(2)}$ as $n\to \infty$, and give Ramanujan-like congruences between $p(n)$ and $ν(n)$ such as $p(5n)\equiv ν(5n)\ (\operatorname{mod} 5)$.

Year: 2020

description: This paper reports from the Enhancing BTEC students’ transition into HE project, which was designed to identify and support effective pedagogical partnerships between academic tutors in both post-16 and Higher Education (HE) institutions. The aim of the project was to more effectively promote and facilitate successful progression to HE amongst students from diverse and non-traditional backgrounds, particularly students from low participation neighbourhoods who have undertaken vocational qualifications, such as BTEC (Business and Technology Education Council) awards in order to progress to HE. The project findings have led to a set of recommendations for building effective collaborative pedagogical partnerships across the post-16 and HE sectors.

description: The formation of extended electron states in one-dimensional nanostructures is of key importance for the function of molecular electronics devices. Here we study the effects of strong electron-phonon interaction on the formation of extended electronic states in intentionally created Cl vacancy pairs and chains in a NaCl bilayer on Cu(111). The interaction between the vacancies was tailored by fabricating vacancy pairs and chains of different orientation and separation with atomic precision using vertical manipulation. Small separation of divacancies led to the formation of symmetric and antisymmetric vacancy states and localized interface-states. By scanning tunneling spectroscopy (STS) we measured their energy splitting and broadening as a function of the inter-vacancy separation. Unexpectedly, the energy splitting between the vacancy states is enlarged by level repulsion resulting from phonon dressing of the electronic states, as evidenced by theory. Already for a few coupled vacancies we observe an emerging band structure of the defect band.

description: A cosmological model with a new variant of Chaplygin gas obeying an equation of state(EoS), $P = Aρ- \frac{B}{ρ^α}$ where $B= B_{0}a^{n}$ is investigated in the context of its thermodynamical behaviour. Here $B_{0}$ and $n$ are constants and $a$ is the scale factor. We show that the equation of state of this `Variable Modified Chaplygin gas' (VMCG) can describe the current accelerated expansion of the universe. Following standard thermodynamical criteria we mainly discuss the classical thermodynamical stability of the model and find that the new parameter, $n$ introduced in VMCG plays a crucial role in determining the stability considerations and should always be \emph{negative.} We further observe that although the earlier model of Lu explains many of the current observational findings of different probes it fails the desirable tests of thermodynamical stability. We also note that for $n < 0$ our model points to a phantom type of expansion which, however, is found to be compatible with current SNe Ia observations and CMB anisotropy measurements. Further the third law of thermodynamics is obeyed in our case. Our model is very general in the sense that many of earlier works in this field may be obtained as a special case of our solution. An interesting point to note is that the model also apparently suggests a smooth transition from the big bang to the big rip in its whole evaluation process.

description: Die vorliegende Arbeit widmet sich Academic Self-Publishing-Verlagen, welche sich auf das kostenfreie Publizieren von Graduierungsarbeiten spezialisiert haben. Im Mittelpunkt der Untersuchung stehen ihr fragwürdiger Ruf im wissenschaftlichen Bibliothekswesen und dessen potenzielles Spannungsverhältnis zu den ethischen Grundsätzen, etablierten Standards und Leitmotiven der Bibliotheksprofession. Die Untersuchung ergründet die Haltungen von Bibliothekarinnen und Bibliothekaren zu diesen Verlagen mittels einer Analyse der wiederkehrenden Diskussionen in der Mailingliste InetBib. Anschließend benennt sie Widersprüche zwischen den Leitmotiven und ethischen Grundsätzen der Profession sowie bibliothekarischer Praxis in Form von Abwehrhaltungen und ‑handlungen gegenüber besagten Dienstleistern. Die Arbeit trifft Ableitungen für erwerbungspraktisches Handeln und es wird beleuchtet, wo wissenschaftliche Bibliotheken selbst strategische Ansätze in Händen halten, um sowohl die bestehenden Bedarfe nach Veröffentlichungsmöglichkeiten für studentische Abschlussarbeiten als auch die anhaltende Nachfrage nach den resultierenden Publikationen kontrolliert bedienen zu können.
