Hawking Radiation for Scalar and Dirac Fields in Five Dimensional Dilatonic Black Hole via Anomalies
Creators: name: Becar, Ramón

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: We study massive scalar fields and Dirac fields propagating in a five dimensional dilatonic black hole background. We expose that for both fields the physics can be describe by a two dimensional theory, near the horizon. Then, in this limit, by applying the covariant anomalies method we find the Hawking flux by restoring the gauge invariance and the general coordinate covariance, which coincides with the flux obtained from integrating the Planck distribution for fermions.

Cosimo I, la magnificenza dell’acqua e la celebrazione del potere: la nuova capitale dello Stato territoriale fra architettura, città e infrastrutture
Creators: name: Ferretti, Emanuela
Publisher: name: Annali di Storia di Firenze
Year: 2015

description: Nel secolo XVI la ‘scienza delle acque’ perfezionava le proprie applicazioni promuovendo non solo una nuova regimentazione idrica del territorio, ma provocando all’interno dei centri storici opere infrastrutturali destinate a segnare la storia delle nostre città. Gli studi, i trattati, che andavano in stampa lungo il Cinquecento, riprendendo la lezione di età classica rilanciavano la rifondazione della disciplina con nuove indagini, applicazioni, tecniche. La captazione delle acque sorgive da canalizzare a servizio della rete urbana, la conseguente realizzazione di fontane monumentali, di lavatoi pubblici, di abbeveratoi, di giardini segreti, mediante la costruzione di condotti interrati, sono tutti interventi che obbligano le città a riconsiderare piazze, strade, espansioni. Firenze partecipa di questa nuova temperie culturale e in questo saggio sono rintracciate le linee guida della politica dell’acque che caratterizza il principato di Cosimo I, evidenziando i nuovi codici espressivi e i nuovi contesti simbolici che informano la committenza del secondo duca mediceo in questo versante delle opere pubbliche.

Energy cascade with small-scales thermalization, counterflow metastability and anomalous velocity of vortex rings in Fourier-truncated Gross-Pitaevskii equation

description: The statistical equilibria of the dynamics of the Gross-Pitaevskii Equation (GPE) with a finite range of spatial Fourier modes are characterized using a new algorithm, based on a stochastically forced Ginzburg-Landau equation (SGLE), that directly generates grand canonical distributions.. The SGLE-generated distributions are validated against finite-temperature GPE-thermalized states and exact low-temperature results. A standard second-order $λ$-transition is exhibited. A new mechanism of GPE thermalization through a direct cascade of energy is found using initial conditions with mass and energy distributed at large scales. A long transient with partial thermalization at small-scales is observed. Vortices are shown to disappear as a prelude to final thermalization and their annihilation is related to the contraction of vortex rings due to mutual friction. Increasing the amount of dispersion at truncation wavenumber is shown to slowdown thermalization and vortex annihilation. A bottleneck that produces spontaneous effective self truncation with partial thermalization is characterized in the limit of large dispersive effects. Metastable counter-flow states are generated using the SGLE algorithm. Spontaneous nucleation of vortex ring is observed and the corresponding Arrhenius law is characterized. Dynamical counter-flow effects on vortex evolution are investigated. Longitudinal effects are produced and measured. A dilatation of vortex rings is obtained for larger counterflows. The vortex ring longitudinal velocity has a strong dependence on temperature, an effect that is related to the presence of finite-amplitude Kelvin waves. This anomalous vortex ring velocity is quantitatively reproduced by assuming equipartition of energy of the Kelvin waves. Orders of magnitude are given for the predicted effects in weakly interacting Bose-Einstein condensates and superfluid $^4{\rm He}$.
Scaling up deliberative democracy for mass publics with digital game experiences

Publisher: name: University of British Columbia
Year: 2022

description: Participants in deliberative minipublics often derive the civic benefits of attitude and knowledge change. However, the minipublic is an ideal form of deliberative democracy that can only accommodate a relatively small number of participants. My dissertation explores a means of scaling up the deliberative minipublic experience as a private or individual practise. I conceptualize and experimentally test a digital deliberation within instrument that invites broad-based use while being substantive enough to meet minipublic standards. The instrument relies on an opinion sorting exercise called a Q sort and gamification techniques. My theoretical claim is that the instrument replicates and facilitates a deliberative process. Specifically, I hypothesize the Q sort creates subjective tensions as participants must read and reflect on a diversity of issue statements. To test my theory, I devise a survey experiment that divides respondents into one control condition (no Q sort) and three treatment conditions (T1: traditional Q sort; T2: gamified Q sort; T3: roleplaying Q sort). I compare treatment pre- and post-surveys results to those of the control group for the following possible civic attitude changes: opinion, knowledge, internal political efficacy, engagement willingness, and deliberative faith. Overall, the results suggest that the deliberation within instrument increases self-reported willingness to participate in civic engagement activities (T1 and T2). And specifically, the respondents indicated their increased willingness to attend future meetings (T1, T2, and T3) and increased willingness to vote (T2). However, the results also indicate that the addition of the roleplay activity may undermine the deliberative efficacy of the Q sort process. Overall, my research partially validates my theory that it is possible to facilitate a deliberation within or private deliberative experience. Thus, a digital deliberation within instrument may be a pathway for scaling up minipublic experiences and spreading its deliberative derived civic benefits.

description: We observe that photon cooling after big bang nucleosynthesis (BBN) but before recombination can remove the conflict between the observed and theoretically predicted value of the primordial abundance of $^7$Li. Such cooling is ordinarily difficult to achieve. However, the recent realization that dark matter axions form a Bose-Einstein condensate (BEC) provides a possible mechanism, because the much colder axions may reach thermal contact with the photons. This proposal predicts a high effective number of neutrinos as measured by the cosmic microwave anisotropy spectrum.

Introduzione al carteggio Benelli-Gozzini, ovvero sulla militanza dei credenti nel Pci

Year: 2014

description: Questo contributo propone lo scambio epistolare tra il cardinale di Firenze Giovanni Benelli e l’intellettuale fiorentino Mario Gozzini, con una introduzione che, alla luce delle carte conservate nel Fondo Gozzini, permette di capire il contesto in cui avvenne il significativo carteggio. Il tema affrontato è il rapporto tra cristianesimo e marxismo, tra credenti e Partito comunista italiano. La vicenda va collocata tra la fine degli anni Settanta e gli inizi degli anni Ottanta, quando un intenso dibattito sul declino della politica e della cultura cattolica nella società contemporanea animava il mondo cattolico italiano (intellettuali, politici e sacerdoti) e, in particolare, quello della città di Firenze. In questo contesto di crisi del partito cattolico, le proposte di ‘riaggregazione’ dell’area cattolica si scontrano con la nascita del gruppo parlamentare della Sinistra indipendente, eletto nelle file del Pci.

Cristiani ed Ebrei dopo la Shoah. Momenti e protagonisti dell’Amicizia ebraico-cristiana di Firenze (1945-1965)
Creators: name: Mazzini, Elena

Year: 2014

description: Il contributo punta a ricostruire la genesi e la storia dell’Amicizia ebraico-cristiana di Firenze (AEC), fondata nel capoluogo toscano nel 1950 con l’intento di promuovere un dialogo interreligioso fra ebrei e cristiani all’indomani dell’Olocausto. La periodizzazione proposta prende avvio dalla data della nascita della stessa associazione e si conclude con il 1965, anno della chiusura del Concilio Vaticano II, che decreta prospettive religiose nuove della Chiesa cattolica nei suoi rapporti con l’ebraismo. Nata per volontà di Arrigo Levasti, Giorgio La Pira, Ines Zilli, Giorgio Spini, Giacomo Devoto, Angelo Orvieto e Aldo Neppi Modona, l’Amicizia fiorentina rappresentava la sezione italiana dell’International Council of Christians and Jews e dell’Amitié judéo-chrétienne di Parigi, divenendo presto un luogo di attività feconde per il dialogo interreligioso in età pre-conciliare.

Metabolites and genetic risk of breast cancer
Creators: name: Samuels, Elizabeth
Publisher: name: University of British Columbia
Year: 2022

description: The mechanisms by which disease-conferring single nucleotide polymorphisms (SNPs) are associated with cancer are not clear, but metabolomics may offer insights to these underlying mechanisms. The objective of this project is to identify metabolites associated with polygenic risk for breast cancer, in order to better understand the mechanistic underpinnings of genetic risk. Using a cross-sectional study design, we conducted regression analysis to identify associations between genetic risk for breast cancer and 223 metabolites. For 143 female participants from the British Columbia Generations Project (BCGP), metabolomics data was generated using the Nightingale Health Ltd nuclear magnetic resonance (NMR) platform, and Maddavat et al’s 2019 polygenic risk score for breast cancer was used to calculate genetic risk. This study finds that very low-density lipoprotein (VLDL) and triglycerides are positively associated with polygenic risk for breast cancer, and high-density lipoprotein (HDL) is negatively associated with polygenic risk for breast cancer. While future work is required to confirm these findings, this study presents a novel study design and biologically plausible findings that are in agreement with existing research into associations between lipoproteins and breast cancer risk. If confirmed, these lipoproteins could be targeted for lifestyle and pharmaceutical interventions among women of high genetic risk and would be valuable targets for future research into disease development.
Dopo la selva. Fascismo e antisemitismo nella cultura cattolica del «Frontespizio» (Firenze, 1929-1940)

description: Tra gli ambienti cattolici che segnarono il dibattito culturale in Italia fra la Conciliazione e l’entrata in guerra, il gruppo fiorentino riunito attorno al «Frontespizio», popolare rivista di ricerca letteraria, divulgazione e apologetica, fu tra i meno propensi ad approfondire sistematicamente questioni di natura sociale e politica. Trattando di alcune fra le colonne portanti di questa esperienza, in primo luogo Giovanni Papini e Piero Bargellini, il saggio cerca tuttavia di documentare la capacità del «Frontespizio» di integrarsi con efficacia – nello stesso momento in cui rivendicava il valore del proprio anticonformismo culturale e della propria schiettezza di toni – nelle coordinate fondamentali del consenso al regime.

Parole di guerra: cattolicesimo e cultura bellica a Firenze (1848-1918)

description: Il saggio esamina il rapporto tra il cattolicesimo fiorentino e la ‘cultura di guerra’ nazional-patriottica, che maturò nel corso dell’Ottocento e preparò il terreno ideologico per lo scoppio del primo conflitto mondiale. Un carattere originale dello studio consistente nel concentrarsi su un arco cronologico di lungo periodo e, al tempo stesso, su un contesto geografico circoscritto. Ciò permette di tracciare alcune linee di evoluzione del discorso nazional-cattolico, cogliendone gli elementi di continuità e di novità di fronte a tre diverse tipologie di guerra (risorgimentale, coloniale, totale). Al centro dell’analisi sono le ‘parole’ degli uomini di Chiesa – sermoni, epigrafi, preghiere – che conferirono plausibilità alla violenza contro il nemico e sacralizzarono, in misura variabile a seconda delle contingenze politiche, il sacrificio per le sorti dell’Italia.

description: We study the mean number counts and two-point correlation functions, along with their covariance matrices, of cosmological surveys such as for clusters. In particular, we consider correlation functions averaged over finite redshift intervals, which are well suited to cluster surveys or populations of rare objects, where one needs to integrate over nonzero redshift bins to accumulate enough statistics. We develop an analytical formalism to obtain explicit expressions of all contributions to these means and covariance matrices, taking into account both shot-noise and sample-variance effects. We compute low-order as well as high-order (including non-Gaussian) terms. We derive expressions for the number counts per redshift bins both for the general case and for the small window approximation. We estimate the range of validity of Limber's approximation and the amount of correlation between different redshift bins. We also obtain explicit expressions for the integrated 3D correlation function and the 2D angular correlation. We compare the relative importance of shot-noise and sample-variance contributions, and of low-order and high-order terms. We check the validity of our analytical results through a comparison with the Horizon full-sky numerical simulations, and we obtain forecasts for several future cluster surveys.

description: Abstract
In this study, the corrosion of rebars was examined in simulated concrete pore (SCP) solution containing 2% sodium chloride (NaCl) with different concentrations of natural green corrosion inhibitors, include Azadirachta Indica (AI) and Calotropis Gigantea (CG), ranging from 0% to 3%. Open circuit potential values, and Linear Polarization resistance (LPR), measurements used in the study to evaluate the inhibitors effectiveness in preventing corrosion. Furthermore, a comparison was made between the efficiency of the organic inhibitors and the chemical inhibitor benzotriazole (BTA). According to the findings, the green inhibitors made from leaf extracts showed passive behavior in SCP solution, particularly when compared to samples that had no inhibitors at all. The green inhibitors showed less passive behavior and comparatively higher negative potential values than the chemical inhibitors. In SCP solution containing 2% NaCl, LPR experiments showed that the inhibitors AI and CG achieved corrosion inhibition efficiencies of 38.85% and 16.21% respectively, at a 2% dosage. By comparison, the SCP solution containing BTA at an identical concentration demonstrated a 38.52% efficiency of inhibition. In a similar line, the outcomes of the accelerated corrosion test shown that the organic inhibitors, at a dose of 2%, had higher corrosion resistance than the control, demonstrating their efficacy in preventing corrosion. The specimens treated with benzotriazole exhibited superior corrosion inhibition, as evidenced by their higher time to induce the corrosion crack and lower anodic current, especially at 2% of dosage.

description: We report experimental and analytical work on spin-transfer torque induced vortex dynamics in metallic nanopillars with in-plane magnetized layers. We study nanopillars with a diameter of 150 nm, containing two Fe layers with a thickness of 15 nm and 30 nm respectively, separated by a 6 nm Ag spacer. The sample geometry is such that it allows for the formation of magnetic vortices in the Fe disks. As confirmed by micromagnetic simulations, we are able to prepare states where one magnetic layer is homogeneously magnetized while the other contains a vortex. We experimentally show that in this configuration spin-transfer torque can excite vortex dynamics and analyze their dependence on a magnetic field applied in the sample plane. The center of gyration is continuously dislocated from the disk center, and the potential changes its shape with field strength. The latter is reflected in the field dependence of the excitation frequency. In the second part we propose a novel mechanism for the excitation of the gyrotropic mode in nanopillars with a perfectly homogeneously magnetized in-plane polarizing layer. We analytically show that in this configuration the vortex can absorb energy from the spin-polarized electric current if the angular spin-transfer efficiency function is asymmetric. This effect is supported by micromagnetic simulations.

Le peculiarità del cattolicesimo liberale fra eredità passate e novità ottocentesche
Creators: name: Manfredi, Marco
Publisher: name: Annali di Storia di Firenze
Year: 2014

description: Il contributo riprende il tema del cattolicesimo liberale fiorentino di primo Ottocento, ‘relativizzando’ e integrando alcuni schemi interpretativi, a partire dall’idea di una sua derivazione prevalentemente settecentesca e inscritta nella storia religiosa toscana. Discutendo il rapporto fra persistenza e discontinuità, il saggio si confronta con questa seconda dimensione, nella convinzione che essa sia stata meno sottolineata rispetto alla prima. Rispetto a studi passati (Spini e Pitocco) e utilizzando come cartina di tornasole il ruolo svolto dagli anni Venti dal ginevrino Vieusseux in qualità di rilevante mediatore culturale fra la dimensione europea e le figure del cattolicesimo liberale, a partire da Lambruschini, si tenta di arricchire il quadro dei contatti con uomini e correnti impegnati su scala continentale in una riforma religiosa. Il contributo opera un bilancio degli esiti storici e delle sopravvivenze di questa ricca esperienza di religiosità riformatrice.

description: We study probe flavor branes supersymmetrically embedded in the Klebanov-Strassler background. The embedding is controlled by a single complex parameter mu related to the quark mass. We study the spectrum of the vector mesons as a function of mu and compare it with the experimental data. Assuming that the rho(2150) meson is a 3S mode we find a remarkable agreement with the masses of the lightest excited rho-mesons. Also, for a certain range of parameters our model exhibits an unusual behavior. The mesons built of the lighter quarks become more heavy than the ones built of the heavier quarks. We comment on a possible connection this phenomenon may have with the masses of the putative pure strange-anti strange mesons.

description: Il presente contributo traccia una sintesi storiografica relativa agli studi sulla Firenze medicea condotti negli ultimi cinquant’anni, privilegiando soltanto quei lavori che si sono occupati più o meno direttamente degli aspetti della storia religiosa della città. Nella seconda parte sono delineate alcune piste di ricerca sulla base di un esiguo, ma significativo campione di fonti edite e inedite. I termini cronologici prescelti coprono il periodo che va dal tardo Quattrocento alle soglie del XVIII secolo; una particolare attenzione è rivolta ai secoli XVI-XVII, emblematici di alcune profonde trasformazioni avvenute nelle esperienze religiose di Firenze, dalla ‘religione delle buone opere’ alla spiritualità della mistica ‘quietista’ di fine Seicento.

Creators: name: Scattigno, Anna
Publisher: name: Annali di Storia di Firenze
Year: 2014

description: Nella prima metà del XVII secolo prendono avvio a Firenze i processi di canonizzazione per Domenica da Paradiso, Caterina de’ Ricci, Maria Maddalena de’ Pazzi. Le cause delineavano un profilo di santità femminile ispirato ai temi della riforma della vita religiosa e della professione monastica e rinnovavano la tradizione di santità della Chiesa fiorentina a partire dalla storia religiosa recente, ancora segnata dalla figura di Girolamo Savonarola. La costruzione di memoria delle monache, testimoni dirette o depositarie di tradizioni orali alimentate all’interno delle comunità femminili di appartenenza, ebbe un rilievo fondamentale nel fissare i tratti di una santità femminile che, se pure rispondeva ai nuovi modelli post-tridentini, manteneva non risolte anche le difformità.

Coulombic effect and renormalization in nuclear pairing

description: We investigate effects of the Coulomb force on the nuclear pairing properties by performing the Gogny Hartree-Fock-Bogolyubov calculations for the $N=20$, $28$, $50$, $82$ and $126$ nuclei. The Coulomb force reduces the proton pair energy and the even-odd mass difference by about 25%, except for nuclei at and around the proton shell or subshell closure. We then propose a renormalization scheme via a reduction factor $γ_p$ for the proton pairing channel. It is found that a single value of $γ_p(=0.90)$ well takes account of the Coulombic effect, for nuclei covering wide range of the mass number and the neutron excess including the nuclei around the shell or subshell closure.

Novel mechanisms and strategies to modulate blood coagulation : the roles of coagulation factor XII and fibrinogen
Creators: name: Juang, Lih Jiin
Publisher: name: University of British Columbia
Year: 2022

description: Both coagulation factor XII (FXII) and fibrinogen have roles in coagulation and inflammation. Modulating the activities and/or concentration of FXII and fibrinogen may have implications for both processes, as well as other interconnected (patho)physiological processes. FXII is thought to be unimportant for hemostasis and instead contributes to thrombosis, supported by the observations that FXII-deficient animals display defective thrombus formation while maintaining normal hemostasis. Despite this, FXII remains conserved across evolution. Silicates are potent activators of FXII and can be found in soil, a ubiquitous material in the environment. Thus, this led to the hypothesis that FXII can contribute to hemostasis when soil, a naturally occurring and silicate-rich material, is introduced into wounds and comes into contact with blood. This thesis showed that soil decreased clot time and blood loss in vitro and in vivo, in a FXII-dependent manner. The procoagulant activities of soil was strongly correlated with the surface concentration of silicon, representing silicate concentration in the samples. This was the first study to describe a conclusive role of FXII in hemostasis. Fibrinogen is implicated in the underlying mechanisms of multiple pathologies. Despite the experimental and therapeutic value in decreasing circulating fibrinogen for long durations, a strategy to achieve this do not exist. Gene silencing strategies such as using siRNA to degrade a target mRNA can deplete the corresponding protein from circulation for long durations. This thesis showed the development and characterization of an siRNA agent targeting fibrinogen alpha chain mRNA (siFga), which is packaged into lipid nanoparticles to enable delivery to the liver, where fibrinogen is made. siFga led to dose-dependent knockdown of circulating fibrinogen that can last for two to three weeks with a single dose. Depletion of circulating fibrinogen also led to decreased levels of platelet fibrinogen. Blood loss did not increase following tail transection in mice at the dose tested. In animal models, treatment with siFga led to attenuated acute phase response, restored macrophage/monocyte migration, and decreased the metastatic potential of tumour cells. These results show that siFga can achieve controllable knockdown of circulating fibrinogen, and that siFga may have clinical utility in diseased states.

description: We study the possibility to extract model independent information about the dynamics of the universe by using Cosmography. We intend to explore it systematically, to learn about its limitations and its real possibilities. Here we are sticking to the series expansion approach on which Cosmography is based. We apply it to different data sets: Supernovae Type Ia (SNeIa), Hubble parameter extracted from differential galaxy ages, Gamma Ray Bursts (GRBs) and the Baryon Acoustic Oscillations (BAO) data. We go beyond past results in the literature extending the series expansion up to the fourth order in the scale factor, which implies the analysis of the deceleration, q_{0}, the jerk, j_{0} and the snap, s_{0}. We use the Markov Chain Monte Carlo Method (MCMC) to analyze the data statistically. We also try to relate direct results from Cosmography to dark energy (DE) dynamical models parameterized by the Chevalier-Polarski-Linder (CPL) model, extracting clues about the matter content and the dark energy parameters. The main results are: a) even if relying on a mathematical approximate assumption such as the scale factor series expansion in terms of time, cosmography can be extremely useful in assessing dynamical properties of the Universe; b) the deceleration parameter clearly confirms the present acceleration phase; c) the MCMC method can help giving narrower constraints in parameter estimation, in particular for higher order cosmographic parameters (the jerk and the snap), with respect to the literature; d) both the estimation of the jerk and the DE parameters, reflect the possibility of a deviation from the LCDM cosmological model.

Coscienze e città: la predicazione a Firenze tra la fine del XIII e gli inizi del XV. Considerazioni introduttive
Creators: name: Gagliardi, Isabella
Publisher: name: Annali di Storia di Firenze
Year: 2014

description: Il contributo s’incentra sulla predicazione dei Frati Minori, dei Frati Predicatori e degli Eremitani di Sant’Agostino a Firenze nel periodo compreso tra gli anni Trenta del XIII secolo e gli inizi del XV secolo, in altre parole dalla lotta al catarismo fino all’affermazione delle Osservanze. In particolare nella predicazione mendicante si ricercano le tracce della visione politica dei frati che si sono avvicendati sui vari pulpiti urbani, cercando di rilevare se esista una peculiarità delle Regole e quali siano le analogie e le differenze tra le prediche di ambiente minoritico, domenicano e agostiniano a riguardo. Si rileva, quindi, una sorta di ‘eccellenza’ politica dei Frati Predicatori che dettero prova di nutrire una ben precisa consapevolezza relativa alla costruzione di una società migliore che muoveva dalla centralità del concetto e della pratica dell’equitas.

Il vescovo e la città. Interessi e conflitti di potere dall’età di Dante a Sant’Antonino
Creators: name: Tanzini, Lorenzo
Publisher: name: Annali di Storia di Firenze
Year: 2014

description: Il saggio delinea una storia dell’episcopato a Firenze dal primo XIV alla metà del XV secolo, in particolare nella prospettiva dei rapporti tra vescovo e governo cittadino. L’obiettivo è quello di comprendere l’originalità del caso fiorentino nel quadro della storia dei rapporti tra vescovi e poteri cittadini nell’Italia tardomedievale. Il punto di partenza è offerto dalla legge statutaria che vietava la nomina di fiorentini a vescovi di Firenze; la norma venne disattesa nel pieno Trecento, quando anzi si venne a creare una forte contiguità dei vescovi con il ceto dirigente cittadino: questo fenomeno alquanto contraddittorio consentì un livello molto alto di controllo politico sulla Chiesa, a sua volta foriero di forti conflitti con il papato. La situazione cambiò nel pieno ’400, quando la figura di Sant’Antonino introdusse un profilo di vescovo per certi versi ‘nuovo’, meno ‘politico’ e molto più dedito alla cura spirituale.

description: La semaine passée, je vous parlais succinctement de ce qu’était une révolution industrielle d’un point de vue économique, en insistant sur la définition schumpétérienne du terme. Aujourd’hui, arrêtons nous sur les implications humaines et géographiques du phénomène et en particulier sur la question des migrations démographiques intérieures, car si la concentration industrielle a favorisé la concentration de la population et la métropolisation, la révolution 4.0, avec ses modèles décentralisés et le développement du télétravail, (en tant qu’applicable seulement à certaines catégories de travailleurs, impossible ou presque en général pour l’artisanat par exemple qui nécessite une présence physique sur le lieu de travail), pourrait à court ou moyen terme transformer le monde du travail des services et la géographie humaine des territoires, mais aussi les systèmes de solidarités dans leurs globalité...
Sum rules, plasma frequencies and Hall phenomenology in holographic plasmas

description: We study the AC optical and hall conductivities of Dp/Dq-branes intersections in the probe approximation and use sum-rules to study various associated transport coefficients. We determine that the presence of massive fundamental matter, as compared to massless fundamental matter described holographically by a theory with no dimensional defects, reduces the plasma frequency. We further show that this is not the case when the brane intersections include defects. We discuss in detail how to implement correctly the regularization of retarded Green's functions so that the dispersion relations are satisfied and the low energy behaviour of the system is physically realistic.

La prova del fuoco. Vita religiosa e identità cittadina nella tradizione del monachesimo fiorentino (seconda metà del secolo XI)
Creators: name: Salvestrini, Francesco
Publisher: name: Annali di Storia di Firenze
Year: 2014

description: Il contributo propone una nuova chiave di lettura del contributo del monachesimo toscano al delinearsi della coscienza religiosa fiorentina durante la seconda metà del secolo XI, quando la città fu protagonista nel movimento riformatore. Il ruolo svolto dai regolari è analizzato in riferimento ai seguaci di Giovanni Gualberto, i vallombrosani, e in particolare alla celebre prova del fuoco di Settimo (1068), che i monaci vollero per provare l’accusa di simonia contro il vescovo di Firenze Pietro Mezzabarba. Questo evento non viene ricondotto, come è stato fatto finora in sede storiografica, alla tradizione delle ordalie, bensì ad una più diretta e originale ispirazione biblica, soprattutto al libro di Daniele; l’episodio portò rapidamente alla deposizione del presule e destò un’eco impressionante ben al di fuori della realtà locale, come dimostrano le relazioni dei religiosi toscani coi principali esponenti della pataria lombarda.

I vescovi dimenticati. Memoria e oblio dei vescovi fiorentini e fiesolani dell’età pre-gregoriana
Creators: name: Faini, Enrico
Publisher: name: Annali di Storia di Firenze
Year: 2014

description: Tra X e XI secolo vescovi importanti ressero le diocesi di Firenze e Fiesole. Nonostante il loro carisma e la loro forza politica, essi sono stati dimenticati. Il saggio si sofferma su questo oblio, cercando di descriverne le modalità e di comprenderne le cause attraverso l’analisi di alcuni testi dei riformatori (Pier Damiani, San Giovanni Gualberto). L’idea di fondo è che l’autorevolezza dei presuli sia stata minata dal sorgere – quasi contemporaneo – della rivalità tra due comunità religiose assai influenti e prossime all’Episcopato: il monastero di San Miniato al Monte e la Canonica della cattedrale fiorentina. Dello scontro approfittarono una potente famiglia (i Visdomini) e il gruppo di monaci raccolti attorno a Giovanni Gualberto. L’offuscarsi del ruolo dei vescovi – impegnati nel sedare la lotta tra monaci e canonici – favorì l’affermazione politica dei Visdomini e la fortuna di Giovanni Gualberto sul piano spirituale.

description: We study self-consistently a microscopic interface between a quantum spin Hall insulator (QSHI) and a superconductor (SC), focusing on properties related to Majorana fermion creation. For an $s$-wave SC we show that odd-in-momentum, or $p$-wave, order parameters exist for all doping levels of the QSHI and that they can be related to different spinless Cooper pair amplitudes. Despite this, the induced superconducting gap in the QSHI always retains its $s$-wave character, validating the commonly used effective model for superconductivity in a topological insulator. For a $d_{xy}$-wave SC, we show that a Majorana mode is only created at finite doping and that there is no excitation gap protecting this mode.
