description: To obtain full-length cDNA coverage with minimal cell input, plate-based single cell sequencing is considered. A significantly overlooked step in the plate-based sequencing workflow includes the isolation of single cells. Although traditional cell sorters have been used for isolating single cells, the high pressure and lengthy sorting time may cause cell death or unwanted alterations in gene expression. In order to observe single cells near a physiologically-relevant state, the speed and pressure of single cell isolation must be carefully considered. Herein, the Namocell Single Cell Dispenser is used for gentle and fast isolation of single cells for downstream single cell sequencing workflows, namely DNA-seq and RNA-seq. The Namo model operating at a low pressure of 2 psi dispensed single target cells directly into a 96-well PCR plate in about 3 minutes – from system initialization to plate – for downstream single cell sequencing.

description: Strategies intended to resolve the problem of time in quantum gravity by means of emergent or hidden timefunctions are considered in the arena of relational particle toy models. In situations with `heavy' and `light' degrees of freedom, two notions of emergent semiclassical WKB time emerge; these are furthermore equivalent to two notions of emergent classical `Leibniz--Mach--Barbour' time. I futhermore study the semiclassical approach, in a geometric phase formalism, extended to include linear constraints, and with particular care to make explicit those approximations and assumptions used. I propose a new iterative scheme for this in the cosmologically-motivated case with one heavy degree of freedom. I find that the usual semiclassical quantum cosmology emergence of time comes hand in hand with the emergence of other qualitatively significant terms, including back-reactions on the heavy subsystem and second time derivatives. I illustrate my analysis by taking it further for relational particle models with linearly-coupled harmonic oscillator potentials. As these examples are exactly soluble by means outside the semiclassical approach, they are additionally useful for testing the justifiability of some of the approximations and assumptions habitually made in the semiclassical approach to quantum cosmology. Finally, I contrast the emergent semiclassical timefunction with its hidden dilational Euler time counterpart.

description: Dirac semimetals (DSMs) are classified into different phases based on the types of the Dirac fermions. Tuning the transition among different types of the Dirac fermions in one system remains challenging. Recently, KMgBi was predicted to be located at a critical state that various types of Dirac fermions can be induced owing to the existence of a flat band. Here, we carried out systematic studies on the electronic structure of KMgBi single crystal by combining angle-resolve photoemission spectroscopy (ARPES) and scanning tunneling microscopy/spectroscopy (STM/STS). The flat band was clearly observed near the Fermi level. We also revealed a small bandgap of ~ 20 meV between the flat band and the conduction band. These results demonstrate the critical state of KMgBi that transitions among various types of Dirac fermions can be tuned in one system.

description: We construct a new class of stable vector bundles suitable for heterotic string compactifications. Using these we describe a novel way to derive the fermionic matter content of the Standard Model from the heterotic string. For this we compactify on an elliptically fibered Calabi-Yau threefold X with two sections, the B-fibration, a variant of the ordinary Weierstrass fibration, which allows X to carry a free involution. We construct rank five vector bundles, invariant under this involution, such that turning on a Wilson line we obtain the Standard Model gauge group and find various three generation models. This rank five bundle is derived from a stable rank four bundle that arises as an extension of bundles pulled-back from the base and twisted by suitable line bundles. We also give an account of various previous results and put the present construction into perspective.

Experimental signatures of non-Abelian statistics in clustered quantum Hall states

description: We discuss transport experiments for various non-Abelian quantum Hall states, including the Read-Rezayi series and a paired spin singlet state. We analyze the signatures of the unique characters of these states on Coulomb blockaded transport through large quantum dots. We show that the non-Abelian nature of the states manifests itself through modulations in the spacings between Coulomb blockade peaks as a function of the area of the dot. Even though the current flows only along the edge, these modulations vary with the number of quasiholes that are localized in the bulk of the dot. We discuss the effect of relaxation of edge states on the predicted Coulomb blockade patterns, and show that it may suppress the dependence on the number of bulk quasiholes. We predict the form of the lowest order interference term in a Fabry-Perot interferometer for the spin singlet state. The result indicates that this interference term is suppressed for certain values of the quantum numbers of the collective state of the bulk quasiholes, in agreement with previous findings for other clustered states belonging to the Read-Rezayi series.

description: We investigate clustering properties of dark matter halos and galaxies to search for optimal statistics and scales where possible departures from general relativity (GR) could be found. We use large N-body cosmological simulations to perform measurements based on the two-point correlation function (2PCF) in GR and in selected modified gravity (MG) structure formation scenarios. As a test-bed, we employ two popular beyond-GR models: $f(R)$ gravity and the normal branch of the Dvali-Gabadadze-Porrati (nDGP) braneworld. We study a range of simulated halo and galaxy populations and reveal a noticeable MG signal in the monopole and quadrupole moments of the redshift-space 2PCF, and in the so-called clustering wedges. However, once expressed in terms of the linear distortion parameter, $β$, the statistical significance of these signals largely diminishes due to a strong degeneracy between MG-enhanced clustering and modified tracer bias. To circumvent this, we consider statistics less dependent on the bias: relative clustering ratios. We generalize the monopole ratio proposed in earlier work to multipole moments and clustering wedges, and introduce a new estimator of the $β$ parameter. The clustering ratios we extract foster noticeable differences between MG and GR models, reaching a maximum deviation of 10\% at 2$σ$ significance for specific variants of $f(R)$ and nDGP. We show that such departures could be measured for $β$ if non-linear effects at intermediate scales are correctly modeled. Our study indicates that the clustering ratios give great promise to search for signatures of MG in the large-scale structure. We also find that the selection of an optimal tracer sample depends on a particular statistics and gravity model to be considered.

description: We measure IRAC colors of extended emission in several fields covering a range of Galactic latitudes and longitudes outside of star forming regions. We determine the nature of the Galactic diffuse emission in Spitzer/IRAC images by combining them with spectroscopic data. We show that PAH features make the emission in the IRAC 5.8 and 8.0 $μ$m channels, whereas the 3.3 $μ$m feature represents only 20 to 50% of the IRAC 3.6 $μ$m channel. A NIR continuum is necessary to account for IRAC 4.5 $μ$m emission and the remaining fraction of the IRAC 3.6 $μ$m emission. This continuum cannot be accounted by scattered light. It represents 9% of the total power absorbed by PAHs and 120% of the interstellar UV photon flux. The 3.3 $μ$m feature is observed to vary from field-to-field with respect to the IRAC 8.0 $μ$m channel. The continuum and 3.3 $μ$m feature intensities are not correlated. We present model calculations which relate our measurements of the PAHs spectral energy distribution to the particles size and ionization state. Cation and neutral PAHs emission properties are inferred empirically from \object{NGC7023} observations. PAHs caracteristics are best constrained in a line of sight towards the inner Galaxy, dominated by the Cold Neutral Medium phase : we find that the PAH cation fraction is about 50% and that their mean size is about 60 carbon atoms. A significant field-to-field dispersion in the PAH mean size, from 40 to 80 carbon atoms, is necessary to account for the observed variations in the 3.3 $μ$m feature intensity relative to the IRAC 8.0 $μ$m flux. However, one cannot be secure about the feature interpretation as long as the continuum origin remains unclear.

It’s possible to recognize in a fragmentary marble sculpture representing the busts of two Apostles, reused on the modern ambo in the basilica of SS. Maria and Donato at Murano, a rare Constantinopolitan work of Palaeologan age. Its careful workmanship appears very close to a group of sculptures in the Archaeological Museum of Istanbul, refined witnesses of that extraordinary cultural climate rightly named Palaeologan Renaissance. On the marble surface of the Murano fragment there are also many remains of polychromy that offer once again an opportunity to draw attention to this widespread technique in the late Byzantine sculpture.

description: We present an algorithm for massive parton evolution which is based on the differentially accurate simulation of soft-gluon radiation by means of a non-trivial azimuthal angle dependence of the splitting functions. The kinematics mapping is chosen such as to to reflect the symmetry of the final state in soft-gluon radiation and collinear splitting processes. We compute the counterterms needed for a fully differential NLO matching and discuss the analytic structure of the parton shower in the NLL limit. We implement the new algorithm in the numerical code Alaric and present a first comparison to experimental data.

description: We derive detailed theoretical models for 1074 nearby stars from the SPOCS (Spectroscopic Properties of Cool Stars) Catalog. The California and Carnegie Planet Search has obtained high-quality echelle spectra of over 1000 nearby stars taken with the Hamilton spectrograph at Lick Observatory, the HIRES spectrograph at Keck, and UCLES at the Anglo Australian Observatory. A uniform analysis of the high-resolution spectra has yielded precise stellar parameters, enabling systematic error analyses and accurate theoretical stellar modeling. We have created a large database of theoretical stellar evolution tracks using the Yale Stellar Evolution Code (YREC) to match the observed parameters of the SPOCS stars. Our very dense grids of evolutionary tracks eliminate the need for interpolation between stellar evolutionary tracks and allow precise determinations of physical stellar parameters (mass, age, radius, size and mass of the convective zone, etc.). Combining our stellar models with the observed stellar atmospheric parameters and uncertainties, we compute the likelihood for each set of stellar model parameters separated by uniform time steps along the stellar evolutionary tracks. The computed likelihoods are used for a Bayesian analysis to derive posterior probability distribution functions for the physical stellar parameters of interest. We provide a catalog of physical parameters for 1074 stars that are based on a uniform set of high quality spectral observations, a uniform spectral reduction procedure, and a uniform set of stellar evolutionary models. We explore this catalog for various possible correlations between stellar and planetary properties, which may help constrain the formation and dynamical histories of other planetary systems.

Una precoce veduta del Canal Grande

description:

The opening chapter of the Venetian veduta, which reached its acme in the 18th century, has often been identified in the series of paintings which in the late 14th and in the 15th centuries celebrated the glory of the Serenissima. One of the events which greatly attracted the attention of contemporaries was the visit of Henry III of France in 1574. Now a canvas of a late mannerist artist belonging to the so called «Sette maniere» area, recently discovered in a private collection, joins the well-known The Landing of Henry III at the Lido (1593) by Andrea Vicentino in the Palazzo Ducale and The Arrival of Henry III at the Foscari Palace, by Palma il Giovane, now in the Dresden Gemäldegalerie. This painting, reproducing contemporary city life on a festive occasion, can be considered an ante litteram veduta. It provides interesting evidence of the grandiose event, probably designed to meet the patrons’ requirements – possibly the Giustinians, who had hosted the king and his retinue in their palace. This detailed reportage gives us a valuable documentary representation and allows us to ideally reconstruct a long stretch of the Grand Canal at the end of the 15th century.

description: Calculating the spectral function of two dimensional systems is arguably one of the most pressing challenges in modern computational condensed matter physics. While efficient techniques are available in lower dimensions, two dimensional systems present insurmountable hurdles, ranging from the sign problem in quantum Monte Carlo (MC), to the entanglement area law in tensor network based methods. We hereby present a variational approach based on a Chebyshev expansion of the spectral function and a neural network representation for the wave functions. The Chebyshev moments are obtained by recursively applying the Hamiltonian and projecting on the space of variational states using a modified natural gradient descent method. We compare this approach with a modified approximation of the spectral function which uses a Krylov subspace constructed from the "Chebyshev wave-functions". We present results for the one-dimensional and two-dimensional Heisenberg model on the square lattice, and compare to those obtained by other methods in the literature.

The analogy between the two papers is quite useful at the level of the quadratic constraints, while I document the differences between the two due to the underlying differences in their linear constraints. I provide a specific minisuperspace example for my emergent semiclassical time scheme and compare it with the hidden York time scheme. Overall, interesting connections are shown between Newtonian, Leibniz--Mach--Barbour, WKB and cosmic times, while the Euler and York hidden dilational times are argued to be somewhat different from these.

description: We study the reaction-diffusion dynamics of Fibonacci anyons in a one dimensional lattice. Due to their non-Abelian nature, besides the position degree of freedom (DOF), these anyons also have a nonlocal internal DOF, which can be characterized by a fusion tree. We first consider a pure-reaction dynamics associated with the internal DOF, which is of intrinsically quantum origin, with either an "all-$τ$" or "completely random" initial fusion tree. These two fusion trees are unstable and likely stable steady states for the internal DOF, respectively. We obtain the decay rate of the anyon number for these two cases exactly. Still using these two initial fusion trees, we study the full reaction-diffusion dynamics, and find an interesting interplay between classical and quantum behaviors: These two fusion trees are still respectively unstable and likely stable steady states of the internal DOF, while the dynamics of the position DOF can be mapped to a hybrid classical $A+A\rightarrow 0$ and $A+A\rightarrow A$ reaction-diffuson dynamics, with the relative reaction rates of these two classical dynamics determined by the state of the nonlocal internal DOF. In particular, the anyon density at late times are given by $ρ(t)=\frac{c}{\sqrt{8π}}(Dt)^{-Δ}$, where $D$ is a non-universal diffusion constant, $Δ=1/2$ is superuniversal, and $c$ is universal and can be obtained exactly in terms of the fusion tree structure. Specifically, $c=\frac{2φ}{φ+1}$ and $c=\frac{2(4φ+3)}{5(φ+1)}$ for the all-$τ$ and completely random configuration respectively, where $φ=\frac{\sqrt{5}+1}{2}$ is the golden ratio. We also study the two-point correlation functions.

Mark Tobey was the first us painter in the XX century who won the Leone d’Oro at the Biennale of 1958. We can consider this event as a goal of an entire program based on spreading American Art all over the «free» world. This award is not very popular among the public that usually recognize as the first Leone d’Oro won by a us artist the one they gave to Rauschenberg in 1964. The Leone d’Oro assigned to Tobey signs for the very first time the importance of us Art in the world of art in a moment in which basically Abstract Expressionism was at the end of his development and in which in Italy the debate among abstracts and realist was in the public eye. With this article I want to point out some questions about American Art and its advance in Italy during the 50es starting from Tobey’s example pursuing to a general consideration on us exhibition strategies at the Venice Biennale during the first period of the Cold War.

Within Conceptual Art attitudes and processes, artists sometimes delegate the execution of an artwork – more or less performative – to a third party through instructions, written or drawn. The following contribution focuses on two specific events, respectively conceived by Sol LeWitt and Bruce Nauman, for the same show – the Tokyo Biennale organized in 1970. What is intended to analyze is the crucial role played by instructions and their importance for future museological reconstructions, when the artist is not present or no longer alive.

description:

A detailed investigation of theatre frame has seldom been undertaken, and far less have non-Western theatres been taken into account for the definition of a universal frame theory. This essay attempts to adjust frame conception and analysis to the needs of the performance system, with particular stress on the semiotic function of the frame, and considering the outcome of different disciplines such as art criticism and linguistics. Through a review of the opinions of Goffman, Simmel, Ortega, Kernodle and Schechner, it explores the idea of frame as a passageway into the art work (therefore into the performance) and focuses on the definition of frame as threshold, lintel, and bridge. This allows to define a possible set of time and space delimiters, inscribing the performance itself within a frame. Examples are taken from theatre practice all over the world.

description: The Mott-insulating rare-earth titanates (RTiO$_3$, R being a rare-earth ion) are an important class of materials that encompasses interesting spin-orbital phases as well as ferromagnet-antiferromagnet and insulator-metal transitions. The growth of these materials has been plagued by difficulties related to overoxidation, which arises from a strong tendency of Ti$^{3+}$ to oxidize to Ti$^{4+}$. We describe our efforts to grow sizable single crystals of YTiO$_3$ and its La-substituted and Ca-doped variants with the optical travelling-solvent floating-zone technique. We present sample characterization $via$ chemical composition analysis, magnetometry, charge transport, neutron scattering, x-ray absorption spectroscopy and x-ray magnetic circular dichroism to understand macroscopic physical property variations associated with overoxidation. Furthermore, we demonstrate a good signal-to-noise ratio in inelastic magnetic neutron scattering measurements of spin-wave excitations. A superconducting impurity phase, found to appear in Ca-doped samples at high doping levels, is identified as TiO.
Study of scalar mesons f_0(980) and f_0(1500) from $B \to f_0(980) K$ and $B \to f_0(1500) K$ Decays

description: Within perturbative QCD approach based on $k_T$ factorization, we analyze the scalar mesons $f_0(980)$ and $f_0(1500)$ productions in B decays. By identifying $f_0(980)$ as the composition of $\bar ss$ and $\bar nn=(\bar uu+\bar dd)/\sqrt2$, we calculate the exclusive decays $B\to f_0(980) K$. We find that the non-factorization $f_0$-emission diagrams can give larger contribution to the branching ratio, than the previous PQCD calculation. Our new results can explain the current experimental data well. Under the assumption of quarkonium dominance, we study the branching ratio of decays $B\to f_0(1500) K$. The results show that in the two-quark picture of $f_0$ meson the contribution from $\bar s s$ component is at the similar size as that from the $\bar n n$ component. Comparing with the data, our results show the preference of $f_0(1500)$ as a member of the ground state of scalar $\bar qq$ nonet. Similar results can also apply to $f_0(1370)$ and $f_0(1710)$, if these mesons are dominated by the quarkonium content. With more experimental data in future, these studies will help us understand the intrinsic characters of these scalar mesons.

description: As is well known, several Roman sources report on the existence of a town foundation ritual, inherited from the Etruscans, which allegedly included astronomical references. However, the possible existence of astronomical orientations in the layout of Roman towns has never been tackled in a systematic way. As a first step in this direction, the orientation of virtually all Roman towns in Italy (38 cities) is studied here. Non-random orientation patterns emerge from these data, aiming at further research in this field.

description: We consider a pair of quantum dot-based spin qubits that interact via microwave photons in a superconducting cavity, and that are also parametrically driven by separate external electric fields. For this system, we formulate a model for spin qubit entanglement in the presence of mutually off-resonant qubit and cavity frequencies. We show that the sidebands generated via the driving fields enable highly tunable qubit-qubit entanglement using only ac control and without requiring the qubit and cavity frequencies to be tuned into simultaneous resonance. The model we derive can be mapped to a variety of qubit types, including detuning-driven one-electron spin qubits in double quantum dots and three-electron resonant exchange qubits in triple quantum dots. The high degree of nonlinearity inherent in spin qubits renders these systems particularly favorable for parametric drive-activated entanglement. We determine multiple common resonance conditions for the two driven qubits and the cavity and identify experimentally relevant parameter regimes that enable the implementation of entangling gates with suppressed sensitivity to cavity photon occupation and decay. The parametrically driven sideband resonance approach we describe provides a promising route toward scalability and modularity in spin-based quantum information processing through drive-enabled tunability that can also be implemented in micromagnet-free electron and hole systems for spin-photon coupling.

description: Urbanisation is a global issue, and rapidly gaining attention from researchers as a major cause of biodiversity loss. Gardens represent a considerable proportion of the urban landscape in the UK and have significant potential to promote urban biodiversity and reduce species loss providing they can be designed and managed appropriately. This research focused on gardens in St Andrews, Scotland, and investigated the influence of environmental variables such as age and area on arachnid and beetle biodiversity with the aim of identifying key predictors of arthropod species richness in urban environments. The key result of this research was that the age and area of individual gardens was not a strong predictor of ground active arthropod biodiversity. This suggests that more recently developed or smaller gardens can contribute to the overall urban region species richness pool as well as larger or more ancient gardens. The most important predictor of ground active arachnid and beetle species richness was the proportion of porous (or 'green') habitat surrounding each garden, and suggested that urban density and habitat connectivity at the regional scale are of key importance. In general, variables measured within gardens (e.g. the provision of microhabitats such as leaf litter, non-managed vegetation, etc.) did not exert any measurable effect on the biodiversity of arachnids or beetles. The findings of this research suggest that the regional availability of heterogeneous greenspace habitat is of high importance for promoting and maintaining urban arthropod biodiversity.
«Istrioni che si beffano di noi». Cronache del teatro italiano dall’età del grande attore fino all’era del regista
Creators: name: Alberti, Carmelo

description:

19th century Italian theatre is chiefly related to its interpreters’ vicissitudes. Actors are professional performers, the heirs of the commedia dell’arte artists. They still conceive acting as a job handed down from father to son. Yet the roles related to masks and stock characters are abandoned, and are replaced by characters whose parts has been written in full by the playwright. The large number of acting companies that are formed and disbanded over a few seasons, fit in a wide network of personal relationships, irrespective of the audience’s support. The desire to uphold the best performances, so that they are not just ephemeral events, is often hindered by everyday life problems. This is confirmed by autobiographical books, actors’ memories, stage chronicles and anecdotes and advertisements. A useful support to theatrics comes from literature and from pictures; these challenge the idea that the fate of this art is to die away night after night, with the final curtain.
Over half a century the rise and fall of ‘the great actor’ as a pivotal drama category takes place, with the contribution of prestigious writers, playwrights and critics, but only in the 1930’s the situation will dramatically change, when the function of the theatre director starts gaining new status in Italy as well.

description: Cryptographic schemes like Fully Homomorphic Encryption (FHE) and Zero-Knowledge Proofs (ZKPs), while offering powerful privacy-preserving capabilities, are often hindered by their computational complexity. Polynomial multiplication, a core operation in these schemes, is a major performance bottleneck. While algorithmic advancements and specialized hardware like GPUs and FPGAs have shown promise in accelerating these computations, the recent surge in AI accelerators (TPUs/NPUs) presents a new opportunity. This paper explores the potential of leveraging TPUs/NPUs to accelerate polynomial multiplication, thereby enhancing the performance of FHE and ZKP schemes. We present techniques to adapt polynomial multiplication to these AI-centric architectures and provide a preliminary evaluation of their effectiveness. We also discuss current limitations and outline future directions for further performance improvements, paving the way for wider adoption of advanced cryptographic tools.

description: One of the main Urry’s lessons is that the tourist experience, with the advent of postmodernism, have started to contribute more to the formation of the identity of people, thanks to the proliferation of information channels and means of transport that have made possible, in fact, a series of practices and dynamics until a few years ago unimaginable (Urry, 2000; Urry & Sheller, 2004, 2006). Today tourism is set up as a cultural experience that is characterized as a time when people, objects, symbols, images and cultures meet, merge and mutually condition.

description: This article discusses the problem of handwriting recognition in Kazakh and Russian languages. This area is poorly studied since in the literature there are almost no works in this direction. We have tried to describe various approaches and achievements of recent years in the development of handwritten recognition models in relation to Cyrillic graphics. The first model uses deep convolutional neural networks (CNNs) for feature extraction and a fully connected multilayer perceptron neural network (MLP) for word classification. The second model, called SimpleHTR, uses CNN and recurrent neural network (RNN) layers to extract information from images. We also proposed the Bluechet and Puchserver models to compare the results. Due to the lack of available open datasets in Russian and Kazakh languages, we carried out work to collect data that included handwritten names of countries and cities from 42 different Cyrillic words, written more than 500 times in different handwriting. We also used a handwritten database of Kazakh and Russian languages (HKR). This is a new database of Cyrillic words (not only countries and cities) for the Russian and Kazakh languages, created by the authors of this work.

description: Scalar and tensorial cosmological perturbations generated in warm inflationary scenarios whose matter-radiation fluid is endowed with a viscous pressure are considered. Recent observational data from the WMAP experiment are employed to restrict the parameters of the model. Although the effect of this pressure on the matter power spectrum is of the order of a few percent, it may be detected in future experiments.

description: The orbit and physical parameters of the previously unsolved SB2 EB V570 Per are derived using high resolution Asiago Echelle spectroscopy and B, V photo-electric photometry. The metallicity from chi^2 analysis is [M/H]=+0.02 +/- 0.03, and reddening from interstellar NaI and KI absorption lines is E(B-V) =0.023 +/- 0.007. The two components have masses of 1.449 +/- 0.006 and 1.350 +/- 0.006 Msun and spectral types F3 and F5, respectively. They are both still within the Main Sequence band (T_1 =6842 +/- 25 K, T_2 =6562 +/- 25 K from chi^2 analysis, R_1 =1.523 +/- 0.030, R_2 =1.388 +/- 0.019 Rsun) and are dynamically relaxed to co-rotation with the orbital motion (Vrot sin i_{1,2} =40 and 36 (+/-1) km/sec). The distance to V570 Per obtained from the orbital solution is 123 +/- 2 pc, in excellent agreement with the revised Hipparcos distance of 123 +/- 11 pc. The observed properties of V570 Per components are compared to BaSTI models computed on purpose for exactly the observed masses and varied chemical compositions. This system is interesting since both components have their masses in the range where the efficiency of convective core overshooting has to decrease with the total mass as a consequence of the decreasing size of the convective core during the central H-burning stage. Our numerical simulations show that, a small but not null overshooting is required, with efficiencies lambda_{OV} =0.14 and 0.11 for the 1.449 and 1.350 Msun components, respectively. This confirms the finding of Paper II on the similar system V505 Per. At the approx 0.8 Gyr age of the system, the element diffusion has reduced the surface metallicity of the models from the initial [M/H]=+0.17 to [M/H]=+0.02, in perfect agreement with the spectroscopically derived [M/H]=+0.02 +/- 0.03 value.

Lieb-Schultz-Mattis Theorem for 1D Quantum Magnets with Antiunitary Translation and Inversion Symmetries

description: We study quantum many-body systems in the presence of an exotic antiunitary translation or inversion symmetry involving time reversal. Based on a symmetry-twisting method and spectrum robustness, we propose that a half-integer spin chain that respects any of these two antiunitary crystalline symmetries in addition to the discrete $\mathbb{Z}_2\times\mathbb{Z}_2$ global spin-rotation symmetry must either be gapless or possess degenerate ground states. This explains the gaplessness of a class of chiral spin models not indicated by the Lieb-Schultz-Mattis theorem and its known extensions. Moreover, we present symmetry classes with minimal sets of generators that give nontrivial Lieb-Schultz-Mattis-type constraints, argued by the bulk-boundary correspondence in 2D symmetry-protected topological phases as well as lattice homotopy. Our results for detecting the ingappability of 1D quantum magnets from the interplay between spin-rotation symmetries and magnetic space groups are applicable to systems with a broader class of spin interactions, including Dzyaloshinskii-Moriya and triple-product interactions.
