On improved fractional Sobolev-Poincaré inequalities
Bartłomiej Dyda, Lizaveta Ihnatsyeva, Antti V. Vähäkangas
We prove a certain improved fractional Sobolev-Poincaré inequality on John domains; the proof is based on the equivalence of the corresponding weak and strong type inequalities. We…
Optical manipulation of the exciton charge state in single layer tungsten disulfide
A. A. Mitioglu, P. Plochocka, J. N. Jadczak +4
Raman scattering and photoluminescence (PL) emission are used to investigate a single layer of tungsten disulfide (WS) obtained by exfoliating n-type bulk crystals. Direct ga…
Decoherence enhanced quantum measurement of a quantum dot spin qubit
Katarzyna Roszak, Łukasz Marcinowski, Paweł Machnikowski
We study the effect of phonons on a proposed scheme for the direct measurement of two-electron spin states in a double quantum dot by monitoring the the noise of the current flowin…
Energy transport and coherence properties of acoustic phonons generated by optical excitation of a quantum dot
D. Wigger, S. Lüker, D. E. Reiter +3
The energy transport of acoustic phonons generated by the optical excitation of a quantum dot as well as the coherence properties of these phonons are studied theoretically both fo…
Asymptotic properties of Brownian motion delayed by inverse subordinators
Marcin Magdziarz, Rene L. Schilling
We study the asymptotic behaviour of the time-changed stochastic process , where is a standard one-dimensional Brownian motion an…
Matricial circular systems and random matrices
Romuald Lenczewski
We introduce and study `matricial circular systems' of operators which play the role of matricial counterparts of circular operators. They describe the asymptotic joint *-distribut…
Rewiring the network. What helps an innovation to diffuse?
Katarzyna Sznajd-Weron, Janusz Szwabinski, Rafal Weron +1
A fundamental question related to innovation diffusion is how the social network structure influences the process. Empirical evidence regarding real-world influence networks is ver…
A Game Theoretic Analysis for Energy Efficient Heterogeneous Networks
Majed Haddad, Piotr Wiecek, Oussama Habachi +1
Smooth and green future extension/scalability (e.g., from sparse to dense, from small-area dense to large-area dense, or from normal-dense to super-dense) is an important issue in…
Integrated density of states for Poisson-Schrödinger perturbations of subordinate Brownian motions on the Sierpiński gasket
Kamil Kaleta, Katarzyna Pietruska-Paluba
We prove the existence of the integrated density of states for subordinate Brownian motions in presence of the Poissonian random potentials on the Sierpiński gasket.
On the equivalence of two expected average cost criteria for semi- Markov control processes
Anna Jaśkiewicz
The two expected average costs used in the theory of semi-Markov control processes with a Borel state space are considered. Under some stochastic stability conditions, we prove tha…
Sharp estimates of transition probability density for Bessel process in half-line
Kamil Bogus, Jacek Malecki
In this paper we study the Bessel process R_t^{(μ)} with index μ\neq 0 starting from x>0 and killed when it reaches a positive level a, where x>a>0. We provide sharp estimates of t…
Proving termination of evaluation for System F with control operators
Małgorzata Biernacka, Dariusz Biernacki, Sergueï Lenglet +1
We present new proofs of termination of evaluation in reduction semantics (i.e., a small-step operational semantics with explicit representation of evaluation contexts) for System…
Excitons in quantum dot molecules: Coulomb coupling, spin-orbit effects and phonon-induced line broadening
J. M. Daniels, P. Machnikowski, T. Kuhn
Excitonic states and the line shape of optical transitions in coupled quantum dots (quantum dot molecules) are studied theoretically. For a pair of electrically tunable, vertically…
From directed path to linear order - the best choice problem for powers of directed path
Andrzej Grzesik, Michał Morayne, Małgorzata Sulkowska
We examine the evolution of the best choice algorithm and the probability of its success from a directed path to the linear order of the same cardinality through th powers of a…
Prediction of breast cancer recurrence using Classification Restricted Boltzmann Machine with Dropping
Jakub M. Tomczak
In this paper, we apply Classification Restricted Boltzmann Machine (ClassRBM) to the problem of predicting breast cancer recurrence. According to the Polish National Cancer Regist…
Bottleneck combinatorial optimization problems with uncertain costs and the OWA criterion
Adam Kasperski, Pawel Zielinski
In this paper a class of bottleneck combinatorial optimization problems with uncertain costs is discussed. The uncertainty is modeled by specifying a discrete scenario set containi…
Enigmatic 4/11 State: A Prototype for Unconventional Fractional Quantum Hall Effect
Sutirtha Mukherjee, Sudhansu S. Mandal, Ying-Hai Wu +2
The origin of fractional quantum Hall effect (FQHE) at 4/11 and 5/13 has remained controversial. We make a compelling case that FQHE is possible here for fully spin polarized compo…
Estimates of transition densities and their derivatives for jump Lévy processes
Kamil Kaleta, Paweł Sztonyk
We give upper and lower estimates of densities of convolution semigroups of probability measures under explicit assumptions on the corresponding Levy measure and the Levy--Khinchin…
State Counting for Excited Bands of the Fractional Quantum Hall Effect: Exclusion Rules for Bound Excitons
Ajit C. Balram, Arkadiusz Wójs, Jainendra K. Jain
Exact diagonalization studies have revealed that the energy spectrum of interacting electrons in the lowest Landau level splits, non-perturbatively, into bands, which is responsibl…
Barriers, exit time and survival probability for unimodal Lévy processes
Krzysztof Bogdan, Tomasz Grzywny, Michał Ryznar
We construct superharmonic functions and give sharp bounds for the expected exit time and probability of survival for isotropic unimodal Lévy processes
