Year: 2013
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: We calculate the probability distribution of work for an exactly solvable model of a system interacting with its environment. The system of interest is a harmonic oscillator with a time dependent control parameter, the environment is modeled by $N$ independent harmonic oscillators with arbitrary frequencies, and the system-environment coupling is bilinear and not necessarily weak. The initial conditions of the combined system and environment are sampled from a microcanonical distribution and the system is driven out of equilibrium by changing the control parameter according to a prescribed protocol. In the limit of infinitely large environment, i.e. $N \rightarrow \infty$, we recover the nonequilibrium work relation and Crooks's fluctuation relation. Moreover, the microcanonical Crooks relation is verified for finite environments. Finally, we show the equivalence of multi-time correlation functions of the system in the infinite environment limit for canonical and microcanonical ensembles.

FreeWheel Social Impact Objectives and Evaluation Model Definition
Creators: name: Luccarelli, Tiziano
Publisher: name: Zenodo
Year: 2018

description: The following activities have been conducted to define the evaluation model of Freewheel and
 its social impact objectives in order to measure the effect generated by the service on
 beneficiaries.
 With inputs from other consortium partners, FreeWheel Theory of change is developed as a way
 to capture a shared vision of the success of the project and define how the social impact of the
 service could be evaluated once it is fully operating.
 The previous deliverables have helped speed up the co-creation process, and get a more
 precise and realistic vision of the change sought with this service. More precisely:
 - Having done the User stories exercise during the 1st General Assembly made it easier
 to conduct remote brainstorming sessions with partners in order to identify key
 stakeholders and key changes they envision once the service is live;
 - Interviews conducted for both the User Archetypes (D2.1) and the Experience Journey
 Map (D2.2) helped to gain clarity on the needs of the End Users and prioritize the key
 areas where the changes are most required.
 The Technical content details the customized method developed to design Freewheel Theory of
 Change. The shared vision of Freewheel by 2022 is the following: “People with physical
 motion limitations (temporary and permanent) have a more autonomous and inclusive
 mobility experience in their daily life.”
FreeWheel Service Blueprint

Publisher: name: Zenodo
Year: 2019

description: The Service Ideation task has the purpose of building the first full overview of FreeWheel service.
 This is possible thanks to all the data coming from research phase developed in WP2, with special
 attention to the Service and Technology Requirements, in continuous update with the advancement of
 the technology in WP3 and of course keeping focused on the Service Design Challenges analyzed and
 defined during task 4.1.
 So the outcome is a Service Blueprint, a diagram that visualizes the relationships between different
 service components (people, props (physical or digital evidence), and processes) that are directly tied to
 touchpoints in a specific customer journey.
 A service blueprint corresponds to a specific customer journey and the specific customer goals
 associated to that journey. This journey can vary in scope. Thus, for the same service, you may have
 multiple blueprints if there are several different scenarios that it can accommodate. For example, with a
 restaurant business, you may have separate service blueprints for the tasks of ordering food for takeout
 versus dining in the restaurant.
 Service blueprints give an organization a comprehensive understanding of its service and the underlying
 resources and processes — seen and unseen to the customer — that make it possible. Focusing on this
 larger understanding (alongside more typical usability aspects and individual touchpoint design) provides
 strategic benefits for the business.

description: We present a spectral and timing analysis of INTEGRAL observations of two high mass X-ray binaries, 4U 1538-522 and 4U 1907+09. Our timing measurements for 4U 1538-522 find the pulse period to have exhibited a spin-up trend until approximately 2009, after which there is evidence for a torque reversal, with the source beginning to spin down to the most recently-measured period of 525.407 +/- 0.001 s. The most recent INTEGRAL observations of 4U 1907+09 are not found to yield statistically significant pulse periods due to the significantly lower flux from the source compared to 4U 1538-522. A spectral model consisting of a power-law continuum with an exponential cutoff and modified by two cyclotron resonance scattering features is found to fit both sources well, with the cyclotron scattering features detected at ~22 and ~49 keV for 4U 1538-522 and at ~18 and ~36 keV in 4U 1907+09. The spectral parameters of 4U 1538-522 are generally not found to vary significantly with flux, and there is little to no variation across the torque reversal. Examining our results in conjunction with previous work, we find no evidence for a correlation between cyclotron line energy and luminosity for 4U 1538-522. 4U 1907+09 shows evidence for a positive correlation between cyclotron line energy and luminosity, which would make it the fourth, and lowest-luminosity, cyclotron line source to exhibit this relationship

description: Aerogel and water Cerenkov detectors were employed to tag kaons for a lambda hypernuclear spectroscopic experiment which used the (e,e'K+) reaction in experimental Hall C at Jefferson Lab (JLab E05-115). Fringe fields from the kaon spectrometer magnet yielded ~5 Gauss at the photomultiplier tubes (PMT) for these detectors which could not be easily shielded. As this field results in a lowered kaon detection efficiency, we implemented a bucking coil on each photomultiplier tubes to actively cancel this magnetic field, thus maximizing kaon detection efficiency.

description: We report positions, velocities and metallicities of 50 ab-type RR Lyrae (RRab) stars observed in the vicinity of the Orphan stellar stream. Using about 30 RRab stars classified as being likely members of the Orphan stream, we study the metallicity and the spatial extent of the stream. We find that RRab stars in the Orphan stream have a wide range of metallicities, from -1.5 dex to -2.7 dex. The average metallicity of the stream is -2.1 dex, identical to the value obtained by Newberg et al. (2010) using blue horizontal branch stars. We find that the most distant parts of the stream (40-50 kpc from the Sun) are about 0.3 dex more metal-poor than the closer parts (within ~30 kpc), suggesting a possible metallicity gradient along the stream's length. We have extended the previous studies and have mapped the stream up to 55 kpc from the Sun. Even after a careful search, we did not identify any more distant RRab stars that could plausibly be members of the Orphan stream. If confirmed with other tracers, this result would indicate a detection of the end of the leading arm of the stream. We have compared the distances of Orphan stream RRab stars with the best-fit orbits obtained by Newberg et al. (2010). We find that model 6 of Newberg et al. (2010) cannot explain the distances of the most remote Orphan stream RRab stars, and conclude that the best fit to distances of Orphan stream RRab stars and to the local circular velocity is provided by potentials where the total mass of the Galaxy within 60 kpc is M_{60}~2.7x10^{11} Msun, or about 60% of the mass found by previous studies. More extensive modelling that would consider non-spherical potentials and the possibility of misalignment between the stream and the orbit, is highly encouraged.

General theory of feedback control of a nuclear spin ensemble in quantum dots

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)

description: We present a microscopic theory of the nonequilibrium nuclear spin dynamics driven by the electron and/or hole under continuous wave pumping in a quantum dot. We show the correlated dynamics of the nuclear spin ensemble and the electron and/or hole under optical excitation as a quantum feedback loop and investigate the dynamics of the many nuclear spins as a nonlinear collective motion. This gives rise to three observable effects: (i) hysteresis, (ii) locking (avoidance) of the pump absorption strength to (from) the natural resonance, and (iii) suppression (amplification) of the fluctuation of weakly polarized nuclear spins, leading to prolonged (shortened) electron spin coherence time. A single nonlinear feedback function as a "measurement" of the nuclear field operator in the quantum feedback loop is constructed which determines the different outcomes of the three effects listed above depending on the feedback being negative or positive. The general theory also helps to put in perspective the wide range of existing theories on the problem of a single electron spin in a nuclear spin bath.

description: In recent years quantum simulation has made great strides culminating in experiments that operate in a regime that existing supercomputers cannot easily simulate. Although this raises the possibility that special purpose analog quantum simulators may be able to perform computational tasks that existing computers cannot, it also introduces a major challenge: certifying that the quantum simulator is in fact simulating the correct quantum dynamics. We provide an algorithm that, under relatively weak assumptions, can be used to efficiently infer the Hamiltonian of a large but untrusted quantum simulator using a trusted quantum simulator. We illustrate the power of this approach by showing numerically that it can inexpensively learn the Hamiltonians for large frustrated Ising models, demonstrating that quantum resources can make certifying analog quantum simulators tractable.

description: The digital transformation is one of the greatest challenges currently facing science, business and society. The lack of digitally qualified staff affects all Alliance organizations both acutely and equally. Rapid action is essential if this challenge is to be met. By pooling the strengths of the Alliance organizations it should be possible to find short or long-term solutions aimed at improving the situation for the whole academic system within a reasonable time-frame. Such cooperative solutions would impact the transition from school to university and beyond to include the time spent studying and acquiring qualifications, and continuing through to higher research training. The range of solutions could extend from the exchange of “good practice” examples through to the collective development of a range of offers, formats and strategies. There follows a description of the various challenges facing the academic system, together with details of the skills required to meet them, and the key features involved in the implementation process.

description: Seismic noise cross correlations are used to image crustal structure and heterogeneity. Typically, seismic networks are only anisotropically illuminated by seismic noise, a consequence of the non-uniform distribution of sources. Here, we study the sensitivity of such a seismic network to structural heterogeneity in a 2-D setting. We compute finite-frequency cross-correlation sensitivity kernels for travel-time, waveform-energy and waveform-difference measurements. In line with expectation, wavespeed anomalies are best imaged using travel times and the source distribution using cross-correlation energies. Perturbations in attenuation and impedance are very difficult to image and reliable inferences require a high degree of certainty in the knowledge of the source distribution and wavespeed model (at least in the case of transmission tomography studied here). We perform single-step Gauss-Newton inversions for the source distribution and the wavespeed, in that order, and quantify the associated Cramér-Rao lower bound. The inversion and uncertainty estimate are robust to errors in the source model but are sensitive to the theory used to interpret of measurements. We find that when classical source-receiver kernels are used instead of cross-correlation kernels, errors appear in the both the inversion and uncertainty estimate, systematically biasing the results. We outline a computationally tractable algorithm to account for distant sources when performing inversions.

Quasi-One-Dimensional Dipolar Quantum Gases

description: In this letter we consider dipolar quantum gases in a quasi-one-dimensional tube with dipole moment perpendicular to the tube direction. We deduce the effective one-dimensional interaction potential and show that this potential is not purely repulsive, but rather has an attractive part due to high-order scattering processes through transverse excited states. The attractive part can induce bound state and cause scattering resonances. This represents the dipole induced resonance in low-dimension. We work out an unconventional behavior of low-energy phase shift for this effective potential and show how it evolves across a resonance. Based on the phase shift, the interaction energy of spinless bosons is obtained using asymptotic Bethe ansatz. Despite of long-range nature of dipolar interaction, we find that a behavior similar as short-range Lieb-Linger gas emerges at the resonance regime.

description: The properties of surface waves in the partially ionized, incompressible magnetized plasma slab are investigated in the present work. The waves are affected by the non ideal MHD effects which causes the finite drift of the magnetic field in the medium. When the finite drift of the magnetic field is ignored, the characteristics of the wave propagation in the partially ionized plasma fluid is similar to the ideal MHD except now the propagation properties depend on the fractional ionization of the medium. In the presence of Hall diffusion, the propagation of the sausage and kink surface waves depends on the level of fractional ionization of the medium. When both the Hall and Pedersen diffusion are present in the medium, the waves undergoes damping. For typical solar parameters, waves may damp over few minutes.

description: We analyze a universe filled with interacting dark matter, a scalar field accommodated as dark radiation along with dark energy plus a decoupled radiation term within the framework of spatially flat Friedmann-Robertson-Walker (FRW) spacetime. We work in a three-dimensional internal space spanned by the interaction vector and use a transversal interaction $\mathbf{Q_t}$ for solving the source equation in order to find all the interacting component energy densities. We asymptotically reconstruct the scalar field and potential from an early radiation era to the late dominate dark energy one, passing through an intermediate epoch dominated by dark matter. We apply the $χ^{2}$ method to the updated observational Hubble data for constraining the cosmic parameters, contrast with the Union 2 sample of supernovae, and analyze the amount of dark energy in the radiation era. It turns out that our model fulfills the severe bound of $Ω_{\rm ϕ}(z\simeq 1100)<0.018$ at $2σ$ level, is consistent with the recent analysis that includes cosmic microwave background anisotropy measurements from the Atacama Cosmology Telescope and the South Pole Telescope along with the future constraints achievable by Planck and CMBPol experiments, and satisfies the stringent bound $Ω_{\rm ϕ}(z\simeq 10^{10})<0.04$ at $2σ$ level in the big-bang nucleosynthesis epoch.

description: Fighting criminal activities in our modern societies required the engagement of intelligent information systems that can analyze crime data geographically and enable new concepts to be deduced from it. These information systems should be able to create visualization of such data as well as have the capability of giving new incite of information, if data is updated whilst maintaining the previously predicted patterns. This paper proposed the use of Formal Concept Analysis, or Galois Lattices, a data analysis technique grounded on Lattice Theory and Propositional Calculus, for the visualization and analysis of crime data. This method considered the set of common and distinct attributes of crimes in such a way that categorization are done based on related crime types, geographical locations and the persons involved.

description: Efficiently controlling the trapping process, especially the trapping efficiency, is central in the study of trap problem in complex systems, since it is a fundamental mechanism for diverse other dynamic processes. Thus, it is of theoretical and practical significance to study the control technique for trapping problem. In this paper, we study the trapping problem in a family of proposed directed fractals with a deep trap at a central node. The directed fractals are a generalization of previous undirected fractals by introducing the directed edge weights dominated by a parameter. We characterize all the eigenvalues and their degeneracies for an associated matrix governing the trapping process. The eigenvalues are provided through an exact recursive relation deduced from the self-similar structure of the fractals. We also obtain the expressions for the smallest eigenvalue and the mean first-passage time (MFPT) as a measure of trapping efficiency, which is the expected time for the walker to first visit the trap. The MFPT is evaluated according to the proved fact that it is approximately equal to reciprocal of the smallest eigenvalue. We show that the MFPT is controlled by the weight parameter, by modifying which, the MFPT can scale superlinealy, linearly, or sublinearly with the system size. Thus, this work paves a way to delicately controlling the trapping process in the fractals.

Mixed valency and site-preference chemistry for Cerium and its compounds: A predictive DFT study

Year: 2013
Subjects: subject: Materials Science (cond-mat.mtrl-sci)

description: Cerium and its technologically relevant compounds are examples of anomalous mixed valency, originating from two competing oxidation states -- itinerant Ce$^{3+}$ and localized Ce$^{4+}$. Under applied stress, anomalous transitions are observed but not well understood. Here we treat mixed valency as an "alloy" involving two valences with competing and numerous site-occupancy configurations, and we use density functional theory with Hubbard U ($i.e.$, DFT+U) to evaluate the effective valence and predict properties, including controlling valence by pseudo-ternary alloying. For Ce and its compounds, such as (Ce-La)$_2$(Fe-Co)$_{14}$B permanent magnets, we find a stable mixed-valent $α$-state near the spectroscopic value of $ν_s=3.53$. Ce valency in compounds depends on its steric volume and local chemistry; for La doping, Ce-valency shifts towards $γ$-like Ce$^{3+}$, as expected from steric volume; for Co doping, valency depends on local Ce-site chemistry and steric volume. Our approach captures the key origins of anomalous valency and site-preference chemistry in complex compounds.

Random walks in weighted networks with a perfect trap: An application of Laplacian spectra

description: In this paper, we propose a general framework for the trapping problem on a weighted network with a perfect trap fixed at an arbitrary node. By utilizing the spectral graph theory, we provide an exact formula for mean first-passage time (MFPT) from one node to another, based on which we deduce an explicit expression for average trapping time (ATT) in terms of the eigenvalues and eigenvectors of the Laplacian matrix associated with the weighted graph, where ATT is the average of MFPTs to the trap over all source nodes. We then further derive a sharp lower bound for the ATT in terms of only the local information of the trap node, which can be obtained in some graphs. Moreover, we deduce the ATT when the trap is distributed uniformly in the whole network. Our results show that network weights play a significant role in the trapping process. To apply our framework, we use the obtained formulas to study random walks on two specific networks: trapping in weighted uncorrelated networks with a deep trap, the weights of which are characterized by a parameter, and Lévy random walks in a connected binary network with a trap distributed uniformly, which can be looked on as random walks on a weighted network. For weighted uncorrelated networks we show that the ATT to any target node depends on the weight parameter, that is, the ATT to any node can change drastically by modifying the parameter, a phenomenon that is in contrast to that for trapping in binary networks. For Lévy random walks in any connected network, by using their equivalence to random walks on a weighted complete network, we obtain the optimal exponent characterizing Lévy random walks, which have the minimal average of ATTs taken over all target nodes.

L?idea fu quella di riunire attorno a un tavolo studiosi provenienti da diversi saperi e ragionare sul complesso e affascinante concetto di �plagio�. Giuristi, studiosi di letteratura, artisti, musicisti, storici si confrontarono da diverse prospettive dando vita a un dibattito interdisciplinare estremamente ricco di riferimenti culturali e spunti di riflessione. Le relazioni presentate nell?aprile 2010 sono state rielaborate, completate da riferimenti bibliografici e raccolte nel volume che oggi vede la luce. La doppia pubblicazione, mediante licenza Creative Commons, sia in formato cartaceo (a pagamento), sia in Open Access (formato digitale gratuito disponibile sull?archivio istituzionale Unitn eprints e sul sito LawTech, alle pagine dedicate al tema del plagio ), completa l?opera di diffusione che aveva preso le mosse, all?indomani delle giornate seminariali, con la messa a disposizione del pubblico delle riprese dei lavori (si veda l?archivio video del sito Web Jus.unitn.it all?URL: ).

description: In a recent note we presented a compact formula for the complete tree-level S-matrix of pure Yang-Mills and gravity theories in arbitrary spacetime dimension. In this paper we show that a natural formulation also exists for a massless colored cubic scalar theory. In Yang-Mills, the formula is an integral over the space of n marked points on a sphere and has as integrand two factors. The first factor is a combination of Parke-Taylor-like terms dressed with U(N) color structures while the second is a Pfaffian. The S-matrix of a U(N)xU(N') cubic scalar theory is obtained by simply replacing the Pfaffian with a U(N') version of the previous U(N) factor. Given that gravity amplitudes are obtained by replacing the U(N) factor in Yang-Mills by a second Pfaffian, we are led to a natural color-kinematics correspondence. An expansion of the integrand of the scalar theory leads to sums over trivalent graphs and are directly related to the KLT matrix. We find a connection to the BCJ color-kinematics duality as well as a new proof of the BCJ doubling property that gives rise to gravity amplitudes. We end by considering a special kinematic point where the partial amplitude simply counts the number of color-ordered planar trivalent trees, which equals a Catalan number. The scattering equations simplify dramatically and are equivalent to a special Y-system with solutions related to roots of Chebyshev polynomials.

description: The total spectral weight \textit{S} of the emergent low-energy quasipaticles in high-temperature superconductors is explored by x-ray absorption spectroscopy. In order to examine the applicability of the Hubbard model, regimes that cover from zero doping to overdoping are investigated. In contrast to mean field theory, we found that \textit{S} deviates from linear dependence on the doping level \textit{p}. The slope of \textit{S} versus \textit{p} changes continuously throughout the whole doping range with no sign of saturation up to \textit{p} = 0.23. Therefore, the picture of Zhang-Rice singlet remains intact within the most prominent doping regimes of HTSC's.

description: We present first-principles calculations of the optical response of monolayer molybdenum disulfide employing the GW-Bethe Salpeter equation (GW-BSE) approach including self-energy, excitonic, and electron-phonon effects. We show that monolayer MoS2 possesses a large and diverse number of strongly bound excitonic states with novel k-space characteristics that were not previously seen experimentally or theoretically. The absorption spectrum is shown to be dominated by excitonic states with binding energy close to $1$~eV and by strong electron-phonon broadening in the visible to ultra-violet range. Our results explain recent experimental measurements and resolve inconsistencies between previous GW-BSE calculations.

Design the FreeWheel Experience Journey Map
Creators: name: Luccarelli, Tiziano
Publisher: name: Zenodo
Year: 2018

description: The Experience Journey Maps (more commonly Experience Maps) in this document have been outlined
 during the human-centered research phase of FreeWheel. Before the Experience Maps we produced
 Behavioural Archetypes to start having a more precise idea about the needs of people with disabilities. For
 building a more reliable set of maps, we are keeping interviewing people with different kind of disabilities (as
 mentioned in the previous deliverable). The results and the new findings are contributing in refining the
 Behavioural Archetypes and giving us ground to outline the maps.
 Involving sponsors users and project’s partners in a series of co-design activities, we landed on the decision
 of using the experience mapping technique for outlining the future viable experience we want to deliver to
 the clients. The relationship with the status-quo, meaning the current experience in the scenarios under
 investigation (going to the shopping mall and to the archeological site) and the related social impact
 (inclusion or exclusion) has been assessed and analyzed through the qualitative interviews and behavioural
 archetypes.
 The current experience in visiting archeological site - or even historic cities - is totally exhausting for people
 with disabilities or their accompanying person. These kinds of experiences are totally conflicting with the
 usual behaviour of avoiding physical stress and fatigue. These places are grouping almost any kind of
 barriers to having a comfortable cultural journey: slopes, irregular pavements, steps, undefined fire plans,
 etc. A person with impaired mobility using a wheelchair is totally absorbed from avoiding obstacles, trying to
 not fall into holes in the pavement, pushing hard trough slopes - or braking continuously with the hands not
 to gain too much speed - sweating all the time for the physical stress.
Spectroscopic analysis of DA white dwarfs with 3D model atmospheres

description: We present the first grid of mean three-dimensional (3D) spectra for pure-hydrogen (DA) white dwarfs based on 3D model atmospheres. We use CO5BOLD radiation-hydrodynamics 3D simulations instead of the mixing-length theory for the treatment of convection. The simulations cover the effective temperature range of 6000 < Teff (K) < 15,000 and the surface gravity range of 7 < log g < 9 where the large majority of DAs with a convective atmosphere are located. We rely on horizontally averaged 3D structures (over constant Rosseland optical depth) to compute <3D> spectra. It is demonstrated that our <3D> spectra can be smoothly connected to their 1D counterparts at higher and lower Teff where the 3D effects are small. Analytical functions are provided in order to convert spectroscopically determined 1D effective temperatures and surface gravities to 3D atmospheric parameters. We apply our improved models to well studied spectroscopic data sets from the Sloan Digital Sky Survey and the White Dwarf Catalog. We confirm that the so-called high-log g problem is not present when employing <3D> spectra and that the issue was caused by inaccuracies in the 1D mixing-length approach. The white dwarfs with a radiative and a convective atmosphere have derived mean masses that are the same within ~0.01 Msun, in much better agreement with our understanding of stellar evolution. Furthermore, the 3D atmospheric parameters are in better agreement with independent Teff and log g values from photometric and parallax measurements.

La nascita della coscienza simbolica: l?antropologia filosofica di Susanne Langer
Creators: name: Brentari, Carlo
Publisher: name: Universit� di Trento. Dipartimento di Studi Letterari, Linguistici e Filologici
Year: 2007

description: Questo volume si propone di esplorare il nucleo fondamentale della concezione filosofico-antropologica di Susanne Langer: la nascita della co�scienza simbolica nella filogenesi della specie umana. Langer intende per coscienza simbolica l?organizzazione mentale basata su rappresenta�zioni simboliche e strumenti linguistici; tale organizzazione dischiude all?uomo inaudite possibilit� di esperienza e lo differenzia qualitativa�mente dagli altri animali. La coscienza simbolica � dunque un?inno�vazione evolutiva che, pur genealogicamente connessa alla configura�zione vitale dell?animale, non � per� riducibile a essa. Non a caso in Langer l?utilizzo delle categorie evolutive tradizionali � accompagnato da un profondo bisogno di riformularle per renderle pi� adeguate alla specificit� dell?uomo. Se l?approccio antropologico di Langer � quindi principalmente cognitivo, va sottolineato per� che i problemi affrontati non possono non portare a frequenti sconfinamenti nella psicoanalisi, nella psicologia e nell?etica. A questo proposito, l?autore dedica parti�colare attenzione alla ricostruzione langeriana dello sviluppo culturale dell?uomo e alla preoccupazione dell?autrice per l?eccessiva logicizza�zione e per lo spietato disincantamento che sono propri della moderna visione del mondo.

description: By using the Kubo linear response theory with the Keldysh Green function approach, we investigate the mechanism leading to the negative differential transmission in system with the equilibrium electron density much smaller than the photon-excited one. It is shown that the negative differential transmission can appear at low probe-photon energy (in the order of the scattering rate) or at high energy (much larger than the scattering rate). For the low probe-photon energy case, the negative differential transmission is found to come from the increase of the intra-band conductivity due to the large variation of electron distribution after the pumping. As for the high probe-photon energy case, the negative differential transmission is shown to tend to appear with the hot-electron temperature being closer to the equilibrium one and the chemical potential higher than the equilibrium one but considerably smaller than half of the probe-photon energy. We also show that this negative differential transmission can come from both the inter- and the intra-band components of the conductivity. Especially, for the inter-band component, its contribution to the negative differential transmission is shown to come from both the Hartree-Fock self-energy and the scattering. Furthermore, the influence of the Coulomb-hole self-energy is also addressed.
