title: Evolution of the Dipole Response for Neutron-Rich Tin Isotopes 124Sn to 132Sn
Creators: name: Horvat, Andrea
Publisher: name: UNSPECIFIED
Year: 2021

description: The Isovector Giant Dipole Resonance (IVGDR) is a collective nuclear excitation mode characterized by an out-of-phase motion of protons and neutrons against each other. As such, it creates a local isospin imbalance. The nuclear matter property that describes the stiffness towards changes in isospin symmetry is called the symmetry energy. Since it acts as the restoring force for the IVGDR, its parameters, namely the value at saturation density (J) and the slope of the density dependence (L), will affect observables related to the collective mode. These parameters, especially L, are still poorly constrained. The dipole polarizability, calculated as the inverse-energy-weighted sum of the transition strength, is one such observable that can be used to place limits on the symmetry energy. However, experiments investigating the IVGDR do not measure it directly, but rather the cross-section distribution over the excitation energy region, from which it is derived. The prospects of placing constraints on the symmetry energy by measuring the total Coulomb excitation cross-section were investigated in this work. The experiment was carried out with the R3B-LAND setup at the GSI Helmholzzentrum für Schwerionenforschung in Darmstadt, Germany. The dipole response of tin isotopes using beams of Sn-124, Sn-128, Sn-130, and Sn-132 was induced via Coulomb excitation in the electromagnetic field of lead target nuclei. The fragment nucleus, neutrons, and gamma-rays resulting from the de-excitation were detected, and the cross-sections for the 1-, 2-, and 3-neutron emission were determined. The measured Coulomb excitation cross-sections were tentatively compared to the ones calculated with families of Skyrme and DDME energy density functionals spanning the range from 30 to 110.8 MeV for L and 26.83 to 38 MeV for J. For the collection of functionals considered, the Coulomb excitation cross-section followed an approximately linear relationship with the polarizability. At this stage, the measurements strongly favor the functionals with lower L values (L<62 MeV). The constraints must be revisited after the inclusion of the strength below the 1-neutron separation threshold, which is yet to be determined from a separate ongoing analysis of the gamma-decay process as part of the same experiment. The results indicate that the Coulomb excitation cross-section should be investigated further as a potentially useful tool to constrain the parameters of the symmetry energy.

description: The objective of the present paper is to study 4-dimensional weakly Ricci symmetric spacetimes $(WRS)_4$ with non-zero constant Ricci scalar. We prove that such a $(WRS)_4$ satisfying $F(R)$-gravity field equations represents a perfect fluid with vanishing vorticity. Some energy conditions are studied under the current setting to constrain the functional form of $F(R)$. We examine a couple of popular toy models in $F(R)$-gravity, $F(R)=e^{αR}$ where $α$ is constant and $F(R)=R-β\tanh(R)$, $β$ is a constant. We also find that the equation of state parameter (EoS) in both models supports the universe's accelerating behavior, i.e., $ω=-1$. According to the recently suggested observations of accelerated expansion, both cases define that the null, weak, and dominant energy conditions justify their requirements while the strong energy conditions violate them.

description: Elemental carbon represents a fundamental building block of matter and the possibility of ferromagnetic order in carbon attracted widespread attention. However, the origin of magnetic order in such a light element is only poorly understood and has puzzled researchers. We present a spectromicroscopy study at room temperature of proton irradiated metal free carbon using the elemental and chemical specificity of x-ray magnetic circular dichroism (XMCD). We demonstrate that the magnetic order in the investigated system originates only from the carbon $π$-electron system.

description: The rules of a game of dice are extended to a "hyper-die" with $n\in\mathbb{N}$ equally probable faces, numbered from 1 to $n$. We derive recursive and explicit expressions for the probability mass function and the cumulative distribution function of the gain $G_n$ for arbitrary values of $n$. A numerical study suggests the conjecture that for $n \to \infty$ the expectation of the scaled gain $\mathbb{E}[H_n]=\mathbb{E}[G_n/\sqrt{n}\,]$ converges to $\sqrt{π/\,2}$. The conjecture is proved by deriving an analytic expression of the expected gain $\mathbb{E}[G_n]$. An analytic expression of the variance of the gain $G_n$ is derived by a similar technique. Finally, it is proved that $H_n$ converges weakly to the Rayleigh distribution with scale parameter~1.

description: This second SHAPE-ID policy brief presents additional recommendations to policymakers and funders on increasing and improving the quality of meaningful arts, humanities and social sciences integration in inter- and transdisciplinary research, maximising effective responses to societal challenges. Interest in interdisciplinarity, policy narratives around innovation, and the increased attention to research impact, are highly intertwined in contemporary funding policy.1 If we understand societal impact in a broad manner as those changes that “affect the cultural, economic, and social life of individuals, organizations, and institutions”2, the need for interdisciplinary and transdisciplinary research (IDR/TDR) with arts, humanities and social sciences (AHSS) involvement makes perfect sense. Disciplines that deeply study the human experience, individuals, societies and cultures understand them in a nuanced way, sensitive to context, beliefs, values, interpretations and history, and are surely necessary to help tackle problems rooted in these human and societal contexts. In this brief, we present recommendations to policymakers to increase and improve the quality of AHSS integration in IDR/TDR, thereby increasing the potential for societal impact from such research. Recommendations are supported by evidence from a series of expert stakeholder workshops organised by SHAPE-ID throughout Europe.

description: Recent developments in neural networks have shown the potential of estimating drag on irregular rough surfaces. Nevertheless, the difficulty of obtaining a large high-fidelity dataset to train neural networks is deterring their use in practical applications. In this study, we propose a transfer learning framework to model the drag on irregular rough surfaces even with a limited amount of direct numerical simulations. We show that transfer learning of empirical correlations, reported in the literature, can significantly improve the performance of neural networks for drag prediction. This is because empirical correlations include `approximate knowledge' of the drag dependency in high-fidelity physics. The `approximate knowledge' allows neural networks to learn the surface statistics known to affect drag more efficiently. The developed framework can be applied to applications where acquiring a large dataset is difficult, but empirical correlations have been reported.

Αυτό το τυπικό δεν επικυρώθηκε από καμιά κυβέρνηση, λόγω της απελευθέρωσης της Ελλάδας από την Τουρκία και αποτελείται από 246 άρθρα, τα οποία επιχειρήθηκαν να σχολιαστούν στην παρούσα εργασία. Επιπλέον, το παραπάνω τυπικό αποτέλεσε τη βάση σύνταξης του ισχύοντος Καταστατικού Χάρτη του Αγίου Όρους, με αποτέλεσμα να υπάρχουν αρκετές ομοιότητες ανάμεσα στα δύο κείμενα.
description: The last statute that was issued during the Ottoman domination was the General Regulations of Mount Athos (1912). This standard has not been ratified by any government, because Greece was liberated from Turkey. The standard consists of 246 articles, which attempted to comment on this work. Furthermore, the above standard was the basis for the drafting of the current Charter of the Mount Athos, with the result that there are several similarities between the two texts.

description: We observed Episodically Active Asteroid (6478) Gault in 2020 with multiple telescopes in Asia and North America and have found that it is no longer active after its recent outbursts at the end of 2018 and start of 2019. The inactivity during this apparation allowed us to measure the absolute magnitude of Gault of H_r = 14.63 +/- 0.02, G_r = 0.21 +/- 0.02 from our secular phasecurve observations. In addition, we were able to constrain Gault's rotation period using time-series photometric lightcurves taken over 17 hours on multiple days in 2020 August, September and October. The photometric lightcurves have a repeating $\lesssim$0.05 magnitude feature suggesting that (6478) Gault has a rotation period of ~2.5 hours and may have a semi-spherical or top-like shape, much like Near-Earth Asteroids Ryugu and Bennu. The rotation period of ~2.5 hours is near to the expected critical rotation period for an asteroid with the physical properties of (6478) Gault suggesting that its activity observed over multiple epochs is due to surface mass shedding from its fast rotation spun up by the Yarkovsky-O'Keefe-Radzievskii-Paddack effect.

description: We investigate the bit-search type irregular decimation algorithms that are used within LFSR-based stream ciphers. In particular, we concentrate on BSG and ABSG, and consider two different setups for the analysis. In the first case, the input is assumed to be a m-sequence; we show that all possible output sequences can be classified into two sets, each of which is characterized by the equivalence of their elements up to shifts. Furthermore, we prove that the cardinality of each of these sets is equal to the period of one of its elements and subsequently derive the first known bounds on the expected output period (assuming that no subperiods exist). In the second setup, we work in a probabilistic framework and assume that the input sequence is evenly distributed (i.e., independent identically distributed Bernoulli process with probability 1/2). Under these assumptions, we derive closed-form expressions for the distribution of the output length and the output rate, which is shown to be asymptotically Gaussian-distributed and concentrated around the mean with exponential tightness.

description: This paper emphasizes that non-linear rotational or diamagnetic susceptibility is characteristic of Bose fluids above their superfluid Tcs. For sufficiently slow rotation or, for superconductors, weak B-fields this amounts to an incompressible response to vorticity. The cause is that there are terms missing in the conventionally accepted model Hamiltonian for quantized vortices in the Bose fluid. The resulting susceptibility can account for recent observations of Chan et al on solid He, and Ong et al on cuprate superconductors.

description: Perturbation theory is a crucial tool for many physical systems, when exact solutions are not available, or nonperturbative numerical solutions are intractable. Naive perturbation theory often fails on long timescales, leading to secularly growing solutions. These divergences have been treated with a variety of techniques, including the powerful dynamical renormalization group (DRG). Most of the existing DRG approaches rely on having analytic solutions up to some order in perturbation theory. However, sometimes the equations can only be solved numerically. We reformulate the DRG in the language of differential geometry, which allows us to apply it to numerical solutions of the background and perturbation equations. This formulation also enables us to use the DRG in systems with background parameter flows, and therefore, extend our results to any order in perturbation theory. As an example, we apply this method to calculate the soliton-like solutions of the Korteweg-de Vries equation deformed by adding a small damping term. We numerically construct DRG solutions which are valid on secular time scales, long after naive perturbation theory has broken down.

description: Angular momentum transport in protostellar discs can take place either radially, through turbulence induced by the magnetorotational instability (MRI), or vertically, through the torque exerted by a large-scale magnetic field that threads the disc. Using semi-analytic and numerical results, we construct a model of steady-state discs that includes vertical transport by a centrifugally driven wind as well as MRI-induced turbulence. We present approximate criteria for the occurrence of either one of these mechanisms in an ambipolar diffusion-dominated disc. We derive ``strong field'' solutions in which the angular momentum transport is purely vertical and ``weak field'' solutions that are the stratified-disc analogues of the previously studied MRI channel modes; the latter are transformed into accretion solutions with predominantly radial angular-momentum transport when we implement a turbulent-stress prescription based on published results of numerical simulations. We also analyze ``intermediate field strength'' solutions in which both modes of transport operate at the same radial location; we conclude, however, that significant spatial overlap of these two mechanisms is unlikely to occur in practice. To further advance this study, we have developed a general scheme that incorporates also the Hall and Ohm conductivity regimes in discs with a realistic ionization structure.

description: Spin glasses are notoriously difficult to study both analytically and numerically due to the presence of frustration and metastability. Their highly non-convex landscapes require collective updates to explore efficiently. Currently, most state-of-the-art algorithms rely on stochastic spin clusters to perform non-local updates, but such "cluster algorithms" lack general efficiency. Here, we introduce a non-equilibrium approach for simulating spin glasses based on classical dynamics with memory. By simulating various classes of 3d spin glasses (Edwards-Anderson, partially-frustrated, and fully-frustrated models), we find that memory dynamically promotes critical spin clusters during time evolution, in a self-organizing manner. This facilitates an efficient exploration of the low-temperature phases of spin glasses.

description: Characteristics of relaxed density profile and conformation of polymer chains are studied by a Monte Carlo simulation on a discrete lattice in three dimensions using different segmental (kink-jump $K$, crank-shaft $C$, reptation $R$) dynamics. Three distinct density regimes, substrate, bulk, and interface, are identified. With the $KC$ segmental dynamics we find that the substrate coverage grows with a power-law, $d_s \propto t^γ$ with a field dependent nonuniversal exponent $γ= 0.23 + 0.7 E$. The bulk volume fraction $d_b$ and the substrate polymer density ($d_s$) increases exponentially with the field ($d_b \propto E^{0.4}$, $d_s \propto E^{0.2}$) in the low field regime. The interface polymer density $d_f$ increases with the molecular weight. With the $KCR$ segmental dynamics, bulk and substrate density decreases linearly with the temperature at high temperatures. The bulk volume fraction is found to decay with the molecular weight, $d_b \propto L_c^{-0.11}$. The radius of gyration remains Gaussian in all density regions.

As a consequence, we find that V(n) is strictly greater than the corresponding number for Schur triples (which is (1/22) n^2 (1+o(1)). Additionally, we disprove the conjecture that V(n) = (1/16) n^2(1+o(1)), as well as a more general conjecture.

description: The present thesis is focused on the nurses of three women, Myrra’s of the Metamorphoses, Skylla’s of the Ciris and Phaedra’s of the homonymous tragedy of Seneca. All these three protagonists felt a love they should never had. Myrra fell in love with her father, Kinyras, Skylla fell in love with Minoas, who was her country’s enemy and Phaedra loved her stepson, Hippolytus. Their nurses intervened to the point where it was every time possible so that their mistresses’ passions should be satisfied. This thesis’s focus is exclusively on the behaviors of the nurses. From the struggle to learn why their ladies suffer so much, the initial shock from learning the truth, their decision to help until the execution of their plans, the thesis follows a line which examines what was the motivation of each nurse. A try to understand these motivations is being held in order to show how these secondary roles gained power enough to provoke the action forward and how they became even for a while the leading roles

description: Among the several reasons that contribute to the success of international commercial arbitration is the maximization of party autonomy and the minimization of court interventions in arbitration. This paper considers international arbitral jurisdiction in view of party autonomy and court interventions. The nature of international commercial arbitration involves both private consensus and public recognition. Private consensus lies in the agreement of the parties. Problems which arise from the agreement and concern arbitral jurisdiction are where arbitral jurisdiction comes from, whether international arbitrators have the power to decide their own jurisdiction, to what extent international arbitrators can assume jurisdiction and to what extent a national court should review the decisions of the arbitrators. The analysis is primarily based on international arbitration rules, published arbitral awards, arbitration legislations and court decisions of countries which have a fairly developed system of international arbitration. The paper concludes that international arbitrators are empowered to deal with their own jurisdiction and their decision is subject only to attack at a national court. International arbitrators and national courts should cooperate to facilitate a speedy resolution of disputes. National laws should play the role of filling in the gaps of international arbitral jurisdiction. Parties should frame their agreement in a way to avoid future uncertainties.

description: Let $G$ be a co-amenable compact quantum group. We show that a right coideal of $G$ is of quotient type if and only if it is the range of a conditional expectation preserving the Haar state and is globally invariant under the left action of the dual discrete quantum group. We apply this result to theory of Poisson boundaries introduced by Izumi for discrete quantum groups and generalize a work of Izumi-Neshveyev-Tuset on $SU_q(N)$ for co-amenable compact quantum groups with the commutative fusion rules. More precisely, we prove that the Poisson integral is an isomorphism between the Poisson boundary and the right coideal of quotient type by maximal quantum subgroup of Kac type. In particular, the Poisson boundary and the quantum flag manifold are isomorphic for any q-deformed classical compact Lie group.

description: Οι Επαγγελματικές Κοινότητες Μάθησης (ΕΚΜ) είναι ένα μοντέλο οργάνωσης του σχολείου που έχει σημαντικές θετικές επιπτώσεις στους μαθητές, στους εκπαιδευτικούς και κατ’ επέκταση στο σχολείο. Στην Ελλάδα το πεδίο αυτό είναι αρκετά ανεξερεύνητο και για το λόγο αυτό σχεδιάστηκε η παρούσα έρευνα επισκόπησης, η οποία αποβλέπει στη λεπτομερή αποτύπωση των απόψεων που έχουν οι εκπαιδευτικοί της Δευτεροβάθμιας Εκπαίδευσης της περιφερειακής ενότητας Θεσσαλονίκης για τις ΕΚM και τις συνιστώσες της. Μέσα από ένα ηλεκτρονικό ερωτηματολόγιο συλλέχθηκαν 202 απαντήσεις, οι οποίες αναλύθηκαν περιγραφικά και επαγωγικά. Τα πορίσματα της έρευνας παρουσίασαν μια γενικά μέτρια προς θετική εικόνα με ενθαρρυντικά στοιχεία για μελλοντική εφαρμογή. Συγκεκριμένα, φάνηκε πως οι εκπαιδευτικοί δεν έχουν τη θεωρητική γνώση γύρω από το μοντέλο των ΕΚΜ, ωστόσο δείχνουν μια θετική τάση ως προς την εφαρμογή τους. Ακόμα, φάνηκε ότι η πρόθεση συμμετοχής τους σε αυτές είναι ανεπηρέαστη από όλα τα δημογραφικά στοιχεία που εξετάστηκαν και πως τέλος, η ωριμότητα των συνιστωσών των ΕΚΜ ποικίλει
description: Professional Learning Communities (PLC) is a model of school organization that triggers remarkable effects on students, teachers and school in general. In Greece the research evidence on this field is quite poor, therefor we designed this survey research which aims to reflect the opinion that educators of the Secondary education of Thessaloniki region have about PLCs and their components. Through an electronic questionnaire 202 answers have been collected and analyzed by descriptive and inductive statistics. The general findings revealed a mediocre to positive situation, with encouraging clues for future application. In particular, educators don’t have the cognitive background of the PLCs theory, however, they are positive on their application. Furthermore, their willingness to participate in the PLCs was not affected by demographics and lastly, the maturity of the components varies

Κατόπιν, έγινε λόγος για τον Οργανισμό Διοικήσεως Εκκλησιαστικής και Μοναστηριακής Περιουσίας και καταγράφηκαν οι νομοθετικές ρυθμίσεις σχετικά με τις απαλλοτριώσεις και τις εκποιήσεις της εκκλησιαστικής περιουσίας μέχρι και την υπογραφή της Σύμβασης «περί εξαγοράς υπό του δημοσίου κτημάτων της Ορθοδόξου Εκκλησίας προς αποκατάστασιν ακτημόνων καλλιεργητών και μικρών κτηνοτρόφων»
description: The aim of the present thesis was the accumulation and study of the legislative adjustments that determined the management of the property of the Church of Greece during the first one hundred twenty years of the first Modern Greek State. Firstly, the legislative adjustments of the Viceroyalty of Othon about the property of Monasteries and their financial results were exhibited and analyzed. Furthermore, the legislative consequence about the expropriations and disposals of the property of Church of Greece were exhibited as well as the following financial results. Moreover, the status quo of the Organization of Administration of the property of Church and Monasteries was exhibited and the legislative consequence about the expropriations and disposals of the property of Church of Greece were registered until the signing of the Contract about the redemption of Orthodox Church’s lands by the public for the rehabilitation of the landless cultivators and the small cattle breeders

description: Recently a lot of new experimental results on open charm hadrons have appeared. In particular many D meson resonances have been discovered. We discuss strong decays of positive and negative parity charmed mesons within heavy meson chiral perturbation theory and study the impact of excited charm states on the determination of the effective meson couplings. Motivated by recent experimental results we also reconsider semileptonic D to P l nu and D to V l nu decays within a model which combines heavy quark symmetry and properties of the chiral Lagrangian. Using limits of soft collinear effective theory and heavy quark effective theory we parametrize the semileptonic form factors. We include excited charm meson states in our Lagrangians and determine their impact on the charm meson semileptonic form factors. In some scenarios of new physics an up-like heavy quark appears, which induces FCNC at tree level for the c to u Z transitions. We investigate FCNC effects in D rare decays in particular the c to u l+ l- transition which might occur in D+ to pi+ l+ l- and D0 to rho0 l+ l-.

description: It is shown that in every dimension n=3j+2, j=1,2,3,..., there exist compact pseudo-Riemannian manifolds with parallel Weyl tensor, which are Ricci-recurrent, but neither conformally flat nor locally symmetric, and represent all indefinite metric signatures. The manifolds in question are diffeomorphic to nontrivial torus bundles over the circle. They all arise from a construction that a priori yields bundles over the circle, having as the fibre either a torus, or a 2-step nilmanifold with a complete flat torsionfree connection; our argument only realizes the torus case.

description: With the growing prevalence of psychological interventions, it is vital to have measures which rate the effectiveness of psychological care to assist in training, supervision, and quality assurance of services. Traditionally, quality assessment is addressed by human raters who evaluate recorded sessions along specific dimensions, often codified through constructs relevant to the approach and domain. This is however a cost-prohibitive and time-consuming method that leads to poor feasibility and limited use in real-world settings. To facilitate this process, we have developed an automated competency rating tool able to process the raw recorded audio of a session, analyzing who spoke when, what they said, and how the health professional used language to provide therapy. Focusing on a use case of a specific type of psychotherapy called Motivational Interviewing, our system gives comprehensive feedback to the therapist, including information about the dynamics of the session (e.g., therapist's vs. client's talking time), low-level psychological language descriptors (e.g., type of questions asked), as well as other high-level behavioral constructs (e.g., the extent to which the therapist understands the clients' perspective). We describe our platform and its performance using a dataset of more than 5,000 recordings drawn from its deployment in a real-world clinical setting used to assist training of new therapists. Widespread use of automated psychotherapy rating tools may augment experts' capabilities by providing an avenue for more effective training and skill improvement, eventually leading to more positive clinical outcomes.

description: Η απολύμανση αποτελεί απαραίτητο στάδιο στην επεξεργασία των νερών. Η πλέον διαδεδομένη μέθοδος είναι αυτή της χλωρίωσης. Κατά το στάδιο αυτό σχηματίζονται παραπροϊόντα χλωρίωσης (DBPs) από την αντίδραση του χλωρίου με την οργανική ύλη των νερών. Περισσότερα από 600 DBPs έχουν καταγραφεί. Από αυτά, μόνο δύο κατηγορίες ενώσεων - τα THMs και τα HΑAs- έχουν θεσμοθετηθεί. Ωστόσο τα τελευταία χρόνια υπάρχει ενδιαφέρον και για τα αζωτούχα παραπροϊόντα χλωρίωσης (N-DBPs), τα οποία αν και βρίσκονται σε χαμηλότερες συγκεντρώσεις από τα θεσμοθετημένα, εμφανίζουν υψηλότερη κυτταροτοξικότητα και γενοτοξικότητα. Στην εργασία αυτή εξετάζεται ο σχηματισμός επτά DBPs (αλογονομένα ακετονιτρίλια, αλογονομένα νιτρομεθάνια, αλογονομένες κετόνες) σε διαφορετικά υποστρώματα (επιφανειακά νερά και απόβλητα). Επιπλέον εξετάστηκαν παράγοντες που επηρεάζουν τον σχηματισμό των παραπάνω ενώσεων. Οι παράγοντες που εξετάστηκαν ήταν ο χρόνος επαφής κατά την χλωρίωση, η δόση του χλωρίου, η συγκέντρωση του βρωμίου και οι πηγές αζώτου που οδηγούν στον σχηματισμό των N-DBPs. Ως πηγές αζώτου χρησιμοποιήθηκαν κυανοβακτήρια και οργανικές ενώσεις που συχνά ανιχνεύονται ως ρύποι σε επιφανειακά νερά (1H-Benzotriazole, Caffeine, Diclofenac, 4-Nitrophenol, EDTA). Τέλος, εξετάστηκε η παρουσία αυτών των παραπροϊόντων σε δείγματα πόσιμου νερού από το δίκτυο της Θεσσαλονίκης
description: Water disinfection is a critical step during water treatment. The most common disinfection process is chlorination. During disinfection process, the reaction between chlorine and natural organic matter leads to the formation of disinfection by-products (DBPs). More than 600 DBPs have been recorded until today, but only two groups of these compounds - THMs and HAAs - have been regulated. Over the last few years, there is an intense interest in Nitrogenous Disinfection By-products (N-DBPs) that represent a group of emerging DBPs. Although the presence of these compounds in chlorinated water is relatively low, there is a growing concern due to their high genotoxicity and cytotoxicity compared to regulated DBPs. This study investigates the formation of seven DBPs (halogenated nitriles, halogenated nitromethanes, halogenated ketones) in different matrices (surface water and wastewater). For this purpose, the formation potential of N-DBPs was investigated under different experimental conditions regarding chlorination contact time, chlorine dose, bromide concentration and nitrogenous organic precursors. Two different species of cyanobacteria and various nitrogenous organic compounds usually observed in waters (1H-Benzotriazole, Caffeine, Diclofenac, 4-Nitrophenol, EDTA) were used as nitrogen source. Finally, the presence of N-DBPs was monitored in drinking water samples of Thessaloniki during three sampling campaigns

description: Using quantum Monte Carlo method, we study, under external magnetic fields, the ground state phase diagram of the two-dimensional spin $S$=1/2 dimer model with an anisotropic intra-plane antiferromagnetic coupling. With the anisotropy $4 \gtrsim Δ\gtrsim 3$, a supersolid phase characterized by a non-uniform bose condensate density that breaks translational symmetry is found. The rich phase diagram also contains a checkerboard solid and two different types of superfluid phase formed by $S_z=+1$ and $S_z=0$ spin triplets, with finite staggered magnetization in z-axis and in-plane direction, respectively. As we show, the model can be realized as a consequence of including the next nearest neighbor coupling among dimers and our results suggest that spin dimer systems may be an ideal model system to study the supersolid phase.
