Lüders bounds of Leggett-Garg inequalities, $\mathcal{PT}$- symmetric evolution and arrow-of-time

description: Leggett Garg inequalities (LGIs) test the incompatibility between the notion of macrorealism and quantum mechanics. For unitary dynamics, the optimal quantum violation of an LGI is constrained by the Lüders bound. However, the LGIs does not provide the necessary and sufficient for macrorealism. A suitably formulated set of no-signaling in time (NSIT) conditions along with the arrow-of-time (AOT) condition provides the same. In this paper, we study two formulations in the three-time LG scenario, viz., the standard LGIs and the recently formulated variant of LGIs when the system evolves under $\mathcal{PT}$-symmetric Hamiltonian. We first demonstrate that the quantum violations of both forms of LGIs exceed their respective Lüders bounds and can even reach their algebraic maximum. We further show that for the case of standard LGI, the violation of Lüders bound can be obtained when both NSIT and AOT conditions are violated. Interestingly, for the case of a variant of LGI, for suitable choices of relevant parameters, the quantum violation can even be obtained when only the AOT is violated but all NSIT conditions are satisfied. This feature has not hitherto been demonstrated. We discuss the further implication of our study.

description: Post-pandemic recovery plans will play an important role in strengthening healthcare systems and rebuilding economies. These stimulus packages and policy responses present a unique opportunity to steer the global economy towards sustainable growth, increase resilience and bolster efforts to tackle the challenge of climate change. This IASS Discussion Paper shows how policymakers could align post-pandemic recovery planning with existing climate goals to unlock co-benefits for sustainable development and climate change mitigation and adaptation.

description: Nærværende artikel undersøger, hvorledes den første kvalitetsrapport er
blevet implementeret i Aalborg Kommune. Vi har foretaget et casestudie
af det konkrete arbejde med rapporterne på forvaltnings-, på skoleleder-
og på politisk niveau. Empirien består i kvalitative interview med
to-fire personer på hver af de nævnte niveauer. Vores resultat i forhold
til implementeringen af kvalitetsrapporten i Aalborg Kommune viser,
at selv i et tilsyneladende enkelt system i form af hierarkisk opbyggede
kontrolinstanser sker der en tillempning på aktørniveau. Hvert niveau i
hierarkiet har således mulighed for at rationere, prioritere og fortolke de
opgaver, der pålægges.

description: Für die Lausitz ist der Kohleausstieg mit einem umfassenden Strukturwandel verbunden. Aktuelle Entscheidungen werden die Region für die nächsten Jahrzehnte prägen. Wegen des angestiegenen Altersdurchschnitts sowie Umfragen, die eine weiterhin hohe Abwanderungsbereitschaft signalisieren (Heidig & Bischoff, 2021), wird in Dokumenten und Debatten zum Strukturwandel betont, wie wichtig es ist, die Lausitz attraktiv für junge Menschen zu gestalten. Die Beteiligung von Kindern und Jugendlichen * kann den Strukturwandelprozess verbessern, weil Ideen junger Menschen neue Impulse geben. * fördert die Motivation junger Menschen, in der Region zu bleiben (Luh et al. 2020). * ist gesetzlich verpflichtend. Die Erfahrungen aus von uns durchgeführten oder begleiteten Prozessen sowie von zahlreichen Studien, wie sie zum Beispiel im 16. Kinder- und Jugendbericht (Bundestag, 2020) zusammengefasst sind, zeigen: Kinder und Jugendliche wollen sich beteiligen und sind dazu auch in der Lage, wenn ein ernsthaftes Interesse an ihren Ansichten besteht und sie Gestaltungsfreiheiten sowie angemessene Unterstützung erhalten. Zugleich ist der Strukturwandel aufgrund seines langen Zeithorizontes und der komplexen Förderarchitekturen in Brandenburg und Sachsen eine Herausforderung für die Beteiligung von Kindern und Jugendlichen. Mit diesem Policy Brief möchten wir konkrete Vorschläge für eine angemessene Umsetzung unterbreiten.

Subjects: subject: Education; Learning Needs; rural education
subject: International and Comparative Education

description: This paper was prepared for participants in the seminar on "Determination of Learning Needs in Rural Areas" to be held at Nairobi
description: One of the major problems faced by developing countries throughout the world is the eradication of poverty, disease and backwardness from rural areas. . In some developing countries, especially in Africa and Asia, the rural population constitutes more than 75% of the total population. Furthermore, of the population in developing countries considered to be in either absolute or relative poverty, more than 80 percent are estimated to live in rural areas. Although this is an old paper, it contains discussion of methods and issues in assessing learning needs which are relevant today. The paper discusses criteria for selecting assessment techniques and then discusses various techniques. It goes on to discuss the level of detail in specifying learning needs. Finally it addresses the important issue of who controls the process which determines whose perceptions of the needs are going to dominate.

description: We investigate the free energy and entropy of the Gaussian massive scalar field theory in the static de Sitter space-time for arbitrary temperature. For the inverse temperatures of the form $β=2 π2^k, \ \ k\in \mathbf{Z}$, in curvature units, we find the explicit form of the free energy and its derivatives with respect to the temperature. There are two types of contributions to the free energy: one is of the "area type" and can be attributed to the horizon, while the other is of the "volume type" and is associated with the interior of the space-time. The latter contribution in the odd-dimensional case in the limit of the week field (large mass or small Hubble constant) significantly depends on the temperature. Namely, for $ β<2π$, the free energy behaves as $ F^{bulk}_β \sim e^{- β\, m} $, while for $β>2π$ it behaves as $ F^{bulk}_β \sim e^{- 2 \, π\, m}$. We also show that even the leading UV contributions to the free energy significantly depend on the state of the theory, which is very unusual. We explain the origin and physical meaning of these observations. As the model example we consider the situation in the Rindler wedge of the flat space-time.

description: This review article offers a survey of the research program focused on a systematic computational search for extreme and potentially singular behavior in hydrodynamic models motivated by open questions concerning the possibility of a finite-time blow-up in the solutions of the Navier-Stokes system. Inspired by the seminal work of Lu & Doering (2008), we sought such extreme behavior by solving PDE optimization problems with objective functionals chosen based on certain conditional regularity results and a priori estimates available for different models. No evidence for singularity formation was found in extreme Navier-Stokes flows constructed in this manner in 3D. We also discuss the results obtained for 1D Burgers and 2D Navier-Stokes systems, and while singularities are ruled out in these flows, the results presented provide interesting insights about sharpness of different energy-type estimates known for these systems. Connections to other bounding techniques are also briefly discussed.

i som efter grundskoleforløbet. Det viser sig, at den
måde, som de unge taler om karakterer og evaluering,
den diskurs der føres herom, spiller en vigtig
rolle i sådanne processers forløb. Det er derfor noget,
som lærere, vejledere, forældre og andre voksne i de
unges omgivelser må være opmærksomme på.

description: In diesem Beitrag wird das aktuelle Interesse der politischen und wirtschaftlichen Entscheidungsträger in den öl- und gasproduzierenden Staaten des Golf-Kooperationsrates (GCC) an der Wasserstoffenergie untersucht. Obwohl die Hauptakteure die fossilen Energieträger, die die politische Ökonomie der Region seit Jahrzehnten bestimmen, weiterhin stärken, erkennen sie zunehmend, dass sich das Zeitalter der Kohlenwasserstoffe dem Ende zuneigt. Dies hat zu einer Zunahme verschiedener "Post-Öl"-Energieinvestitionen geführt, zu denen in letzter Zeit auch Wasserstoff gehört. In diesem Diskussionspapier wird untersucht, warum dies der Fall ist, d. h. warum die politischen und unternehmerischen Spitzen des Golf-Kooperationsrates (GCC) an der Förderung von Wasserstoffenergiesystemen in der Region interessiert sind. Es wird gezeigt, dass die Bestrebungen zur Herstellung von "grünem" Wasserstoff - die ihren Ursprung in Europa und insbesondere in Deutschland haben - zunehmend als eine Möglichkeit gesehen werden, den grünen Ruf der Region zu verbreiten und gleichzeitig Investitionen in "blauen" Wasserstoff zu unterstützen, die von den staatlichen Öl- und Gasriesen in den Vereinigten Arabischen Emiraten (VAE) und Saudi-Arabien gefördert werden.

description: Energy distribution of electrons in the plasma sustained by the electron-cyclotron resonance (ECR) discharge has a complicated shape as a function of various parameters that still remains unknown. Meanwhile, it is an important plasma characteristic. Some methods and approaches give the possibility to estimate or measure the properties of the distributions of the electrons lost from the plasma. One of them, similar to the ion mass spectrometry, was used in this work to obtain such distributions in the non-classical continuous ECR ion source with high (up to $ 50-100$ W/cm$ ^ 3 $) energy input for the first time along with bremsstrahlung spectra. For certain parameters, a threshold-like regime was discovered, which comprised of the bursts of energetic electrons, bremsstrahlung and, supposedly, the development of kinetic instabilities.

description: Resonance fluorescence of two-level quantum systems has emerged as a powerful tool in quantum information processing. Extension of this approach to higher-level systems provides new opportunities for quantum optics applications. Here we introduce a coherent driving scheme of a three-level ladder system utilizing Autler-Townes and ac Stark effects by resonant excitation with two laser fields. We propose theoretically and demonstrate experimentally the feasibility of this approach towards all-optical spectral tuning of quantum dot-based single-photon sources and investigate photon indistinguishability and purity levels. Our tuning technique allows for fast optical control of the quantum emitter spectrum which paves the way towards temporal and spectral shaping of the single photons, formation of topological Floquet states or generation of high-dimensional frequency-encoded quantum states of light.
Thermodynamics for higher dimensional rotating black holes with variable Newton constant

description: The extensivity for the thermodynamics of general $D$-dimensional rotating black holes with or without a cosmological constant can be proved analytically, provided the effective number of microscopic degrees of freedom and the chemical potential are given respectively as $N=L^{D-2}/G, μ= GTI_D/L^{D-2}$, where $G$ is the variable Newton constant, $I_D$ is the Euclidean action and $L$ is a constant length scale. In the cases without a cosmological constant, i.e. the Myers-Perry black holes, the physical mass and the intensive variables can be expressed as explicit macro state functions in the extensive variables in a simple and compact form, which allows for an analytical calculation for the heat capacity. The results indicate that the Myers-Perry black holes with zero, one and $k$ equal rotation parameters are all thermodynamically unstable.

Creators: name: Singh, Pradeep A.
Publisher: name: Research Institute for Sustainability (RIFS)
Year: 2023

description: The invocation of a treaty provision known as the "two-year rule" at the International Seabed Authority effectively placed a deadline on the Authority to complete the adoption of regulations for exploitation activities within two years, i.e. by 9 July 2023. However, it is not a hard "deadline" and it is likely that the Authority might miss this deadline. In recent months, the member states of the Authority have commenced discussions on what would happen if the deadline is missed (or the "what if scenario"). It follows that missing the deadline will give rise to a host of open legal questions. Building on previous work, this discussion paper attempts to provide some insights and possible interpretations to answer some of those questions.
Classical Daoism

Publisher: name: Database of Religious History (DRH)
Year: 2019

description: Classical Daoism is a "catch-all" term for a set of beliefs and practices evidenced from texts dating from the Warring States period to the Early Han Dynasty in China. Scholars have deduced that these texts, having similar ideas regarding the world, must have been written by an informal community of like-minded practitioners. It was therefore not an organized religion (though early and later organized Daoism does espouse some of the same basic principles). Because the state and provenance of these texts is unclear, little is known about the social organization of Classical Daoists. However, it is clear that Classical Daoists believe in the Dao as the guiding principle of the universe, outline cultivation practices that have a goal of becoming one with or attaining the Dao, and in some cases, suggest strategies for rulership in accordance with the Dao.
Lakher also known as “Maras”

description: The Lakher, who refer to themselves as the Mara, “inhabit the south-eastern corner of the Lushai Hills district, south of the Haka sub-division of the Chin Hills, and the extreme north of the Arakan Hill Tracts” (Parry, 1932:1). This area is located primarily in the Indian state of Mizoram, but also extends into Burma and Bangladesh. The Lakher are comprised of six groups: the Tlongsai, Hawthai, Zeuhnang, Sabeu, Lialai, and Heima. These groups are further subdivided into clans, but the village (led by a chief or bei) is the primary social, political, and religious unit. This entry focuses around the time of 1930; just six years after the Lakhers came under British rule. At this time, Lakher customs remained largely unchanged by foreign influence (British government and Christian Missionaries), and traditional religious beliefs were still held by the majority of the Lakher population. The Lakher’s supreme high god is known as Khazangpa, who is believed to have created the world and holds control over all its inhabitants. Other supernatural beings include zang (tutelary deities/guardian spirits), leurahripas (demons/evil spirits), and ancestral spirits. No official religious practitioners are present; the heads of households perform most rites and sacrifices. Mediums (zhazanghneipa) have special communication with spirits, and typically use this communication for medicinal purposes (such as finding out what sacrifices to prescribe a woman hoping to increase her fertility, for example). Ceremonies are present, and accompany most major life-cycle events. Also present is a yearly cycle of rites/feasts associated primarily with agriculture and the propitiation of supernatural beings. Zhazangpina is the most important sacrificial rite, which is performed by the head of a household in hopes of pleasing Zhazangpa, who will in turn bless the household with good health and prosperity. The Lakher’s religious beliefs are bound up with the functioning of society as a whole, so this entry considers the religious group to be coterminous with the society at large.

description: Primordial black holes (PBHs) are convenient candidates to explain the elusive dark matter (DM). However, years of constraints from various astronomical observations have constrained their abundance over a wide range of masses, leaving only a narrow window open at $10^{17}\,{\rm g} \lesssim M \lesssim 10^{22}\,$g for all DM in the form of PBHs. We reexamine this disputed window with a critical eye, interrogating the general hypotheses underlying the direct photon constraints. We review 4 levels of assumptions: i) instrument characteristics, ii) prediction of the (extra)galactic photon flux, iii) statistical method of signal-to-data comparison and iv) computation of the Hawking radiation rate. Thanks to Isatis, a new tool designed for the public Hawking radiation code BlackHawk, we first revisit the existing and prospective constraints on the PBH abundance and investigate the impact of assumptions i)-iv). We show that the constraints can vary by several orders of magnitude, advocating the necessity of a reduction of the theoretical sources of uncertainties. Second, we consider an "ideal" instrument and we demonstrate that the PBH DM scenario can only be constrained by the direct photon Hawking radiation phenomenon below $M_{\rm max} \sim 10^{20}\,$g. The upper part of the mass window should therefore be closed by other means.

description: Den nyligt afsluttede, landsdækkende evaluering af loven om pædagogiske læreplaner har vist, at pædagogiske læreplaner indtil nu har været en faglig succes i dagtilbuddene. Men den viser også, at evalueringsarbejdet endnu spiller en begrænset rolle i arbejdet. Hvis de pædagogiske læreplaner fremadrettet skal forblive en succes og medvirke til at udvikle den pædagogiske praksis, er evalueringskapacitet et vigtigt omdrejningspunkt. Med systematisk evaluering som en integreret del af arbejdet med de pædagogiske læreplaner har de - som en form for ”systemtænknings-redskab -” potentiale til at være løftestang for organisatorisk læring i dagtilbuddet - den læring, som er en forudsætning for kvalitetsudviklingen af den pædagogiske praksis. Vi sætter i denne artikel fokus på sammenhængen mellem pædagogiske læreplaner, evaluering og organisatorisk læring i dagtilbuddene.

description: W ostatnich latach coraz większą uwagę zyskują wyzwania stojące przed europejskimi regionami związane ze zmianami strukturalnymi w kierunku zrównoważonego rozwoju. Łużyce, leżące na granicy Niemiec i Polski, doświadczają znacznej presji związanej z transformacją. Krajowe i europejskie programy finansowania, m.in. w ramach Europejskiego Zielonego Ładu, mają na celu łagodzenie skutków odchodzenia od wydobycia i konsumpcji węgla. Niedawno przyjęty unijny Mechanizm Sprawiedliwej Transformacji ma za zadanie wspieranie zrównoważonych zmian strukturalnych poprzez pomoc pracownikom i przyczynianie się do dywersyfikacji gospodarki w najbardziej dotkniętych obszarach. Niniejszy Policy Brief przedstawia trzy rekomendacje związane z wykorzystaniem funduszy UE w polsko-niemieckim obszarze granicznym w celu wspierania sprawiedliwej transformacji. Po pierwsze, fundusze udostępnione w ramach Mechanizmu powinny być wykorzystywane w porozumieniu z regionalnymi interesariuszami w Łużycach w celu uzupełnienia krajowych środków wsparcia. Dalsze programy finansowania ukierunkowane na różne obszary polityki publicznej powinny być wykorzystane w celu wzmocnienia spójności w całym regionie. W tym kontekście szczególnie interesujące są programy zarządzane centralnie przez Komisję Europejską (tzn. nie podlegające zarządzaniu dzielonemu z rządami krajowymi). Ściślejsza współpraca polityczna i gospodarcza, w połączeniu z głębszą wymianą doświadczeń, może przyspieszyć integrację regionalną i ukierunkować procesy przekształceń strukturalnych na osiągnięcie trwałych rezultatów. Użycie tych programów w obszarze granicznym obarczone jest jednak praktycznymi przeszkodami, które należy pokonać. Ponadto powyżej wymienione działania powinny być realizowane zgodne z celami zrównoważonego rozwoju (SDGs), przyczyniać się do osiągnięcia celu, jakim jest neutralność klimatyczna, a także do złagodzenia społecznych skutków transformacji strukturalnej na wszystkich poziomach.

description: We explore possible extensions of the $t$-channel and $s$-channel unitary model of high energy evolution in zero transverse dimensions appropriate to very high energy/atomic number where the dipole density in a toy hadron is parametrically high.We suggest that the appropriate generalization is to allow emission of more than one dipole in a single step of energy evolution. We construct explicitly such a model that preserves the $t$-channel and s-channel unitarity and have the correct low density limit, and study the particle multiplicity distribution resulting from this evolution. We consider initial conditions of a single dipole and many dipoles at initial rapidity. We observe that the saturation regime in this model is preceded by a parametric range of rapidities $\frac{1}{α_s}\ln\frac{1}{α_s}

description: We describe the Perkins INfrared Exosatellite Survey (PINES), a near-infrared photometric search for short-period transiting planets and moons around a sample of 393 spectroscopically confirmed L- and T-type dwarfs. PINES is performed with Boston University's 1.8 m Perkins Telescope Observatory, located on Anderson Mesa, Arizona. We discuss the observational strategy of the survey, which was designed to optimize the number of expected transit detections, and describe custom automated observing procedures for performing PINES observations. We detail the steps of the $\texttt{PINES Analysis Toolkit}$ ($\texttt{PAT}$), software that is used to create light curves from PINES images. We assess the impact of second-order extinction due to changing precipitable water vapor on our observations and find that the magnitude of this effect is minimized in Mauna Kea Observatories $\textit{J}$-band. We demonstrate the validity of $\texttt{PAT}$ through the recovery of a transit of WASP-2 b and known variable brown dwarfs, and use it to identify a new variable L/T transition object: the T2 dwarf WISE J045746.08-020719.2. We report on the measured photometric precision of the survey and use it to estimate our transit detection sensitivity. We find that for our median brightness targets, assuming contributions from white noise only, we are sensitive to the detection of 2.5 $R_\oplus$ planets and larger. PINES will test whether the increase in sub-Neptune-sized planet occurrence with decreasing host mass continues into the L and T dwarf regime.

description: This exercise investigated the impact of South Africa's draft Sector Emission Targets (SETS), established under the Paris Agreement, on the nation's electricity sector energy mix. Faced with aggressive CO2eq reduction targets for 2025-2030, this research examines the resulting shifts in power generation. The main findings indicate a significant decline in traditional coal power generation to comply with the SETS. Consequently, the study reveals a corresponding increase in investment and deployment of alternative technologies, specifically wind and gas, reshaping the energy mix within South Africa's power sector.

description: Diode laser self-injection locking (SIL) to a whispering gallery mode of a high quality factor resonator is a widely used method for laser linewidth narrowing and high-frequency noise suppression. SIL has already been used for the demonstration of ultra-low-noise photonic microwave oscillators and soliton microcomb generation and has a wide range of possible applications. Up to date, SIL was demonstrated only with a single laser. However, multi-frequency and narrow-linewidth laser sources are in high demand for modern telecommunication systems, quantum technologies, and microwave photonics. Here we experimentally demonstrate the dual-laser SIL of two multifrequency laser diodes to different modes of an integrated Si$_3$N$_4$ microresonator. Simultaneous spectrum collapse of both lasers, as well as linewidth narrowing and high-frequency noise suppression , as well as strong nonlinear interaction of the two fields with each other, are observed. Locking both lasers to the same mode results in a simultaneous frequency and phase stabilization and coherent addition of their outputs. Additionally, we provide a comprehensive dual-SIL theory and investigate the influence of lasers on each other caused by nonlinear effects in the microresonator.
Epidemics on evolving networks with varying degrees

description: Epidemics on complex networks is a widely investigated topic in the last few years, mainly due to the last pandemic events. Usually, real contact networks are dynamic, hence much effort has been invested in studying epidemics on evolving networks. Here we propose and study a model for evolving networks based on varying degrees, where at each time step a node might get, with probability $r$, a new degree and new neighbors according to a given degree distribution, instead of its former neighbors. We find analytically, using the generating functions framework, the epidemic threshold and the probability for a macroscopic spread of disease depending on the rewiring rate $r$. Our analytical results are supported by numerical simulations. We find surprisingly that the impact of the rewiring rate $r$ has qualitative different trends for networks having different degree distributions. That is, in some structures, such as random regular networks the dynamics enhances the epidemic spreading while in others such as scale free the dynamics reduces the spreading. In addition, for scale-free networks, we reveal that fast dynamics of the network, $r=1$, changes the epidemic threshold to nonzero rather than zero found for $r<1$, which is similar to the known case of $r=0$, i.e., a static network. Finally, we find the epidemic threshold also for a general distribution of the recovery time.

description: We show that the integrability of the $SO(N)/SO(N-1)$ Principal Chiral Model (PCM) originates from the Pohlmeyer reduction of the $O(N)$ Non Linear Sigma Model (NLSM). In particular, we show that the Lax pair of the PCM is related upon redefinitions and identification of parameters to the zero curvature condition, which is a consequence of the flatness of the enhanced space used in the Pohlmeyer reduction. This identification provides the solution of the auxiliary system that corresponds to an arbitrary NLSM/PCM solution.

Angular momentum transport in a contracting stellar radiative zone embedded in a large scale magnetic field

description: Some contracting or expanding stars are thought to host a large-scale magnetic field in their radiative interior. By interacting with the contraction-induced flows, such fields may significantly alter the rotational history of the star. They thus constitute a promising way to address the problem of angular momentum transport during the rapid phases of stellar evolution. In this work, we aim at studying the interplay between flows and magnetic fields in a contracting radiative zone. We propose a scenario that may account for the post-main sequence evolution of solar-like stars, in which a quasi-solid rotation can be maintained by a large-scale magnetic field during a contraction timescale. Then, an axisymmetric instability would destroy this large-scale structure and enables the differential rotation to set in. Such a contraction driven instability could also be at the origin of the observed dichotomy between strongly and weakly magnetic intermediate-mass stars.

description: The high volume of plastic packaging currently consumed in Germany poses a complex socio-ecological risk. As part of the BMBF-funded ENSURE research consortium, environmental psychologists at the Institute for Advanced Sustainability Studies (IASS) in Potsdam have studied various policy options to promote a reduction in individual consumption of plastic food packaging. A representative nationwide survey of 1,200 persons conducted by the researchers shows that 92 per cent of the interviewed consumers consider plastic waste in the environment a threat to the preservation of our natural resources and the foundations of life. Despite this widespread awareness, the consumption of plastic packaging continues to grow: In 2018, Germany generated over three million tonnes of plastic packaging waste; more than double the amount produced in 1997. The findings of the ENSURE project indicate that consumers are willing and indeed wish to reduce their consumption of plastic packaging; however, they are hindered by personal and structural barriers. Political action is needed to break down these barriers to change and support consumers in their efforts. This IASS Policy Brief presents three strategic policy recommendations that could help reduce the consumption of packaging in daily life. Following an outline of the broader context and key issues, these three recommendations are explained in detail. In conclusion, we highlight the need for a systemic approach to the reduction of plastic packaging.
A Framework for Characterizing Transmission Spectra of Exoplanets with Circumplanetary Rings

description: Recent observations revealed that several extremely low-density exoplanets show featureless transmission spectra. While atmospheric aerosols are a promising explanation for both the low density and featureless spectra, there is another attractive possibility: the presence of circumplanetary rings. Previous studies suggested that rings cause anomalously large transit radii. However, it remains poorly understood how rings affect the transmission spectrum. Here, we provide a framework to characterize the transmission spectra of ringed exoplanets. We develop an analytical prescription to include rings in the transmission spectra for arbitrarily viewing geometries. We also establish a simple post-processing model that can include the ring's effects on precomputed ring-free spectra. The ring flattens the transmission spectrum for a wide range of viewing geometries, consistent with the featureless spectra of extremely low-density exoplanets. Near-future observations by JWST at longer wavelengths would be able to distinguish the aerosol and ring scenarios. We also find that rocky rings might cause a silicate feature at $\sim$10 $μ$m if the ring's optical depth is around unity. Thus, the ring's spectral features, if detected, would provide tight constrains on the physical properties of exoplanetary rings. We also discuss the ring's stability and suggest that thick rings are sustainable only at the equilibrium temperature of $\lesssim$300 K for the ring's age comparable to Kepler planets. This might indicate the intrinsic deficit of thick rings in the Kepler samples, unless rings are much younger than the planets as suggested for Saturn.
