Yet, it may be easy to formally specify a controller. For instance, for a pipelined processor it suffices to state that the visible behavior of the pipelined system should be identical to a non-pipelined reference system (Burch-Dill paradigm). We present a novel procedure to efficiently synthesize multiple Boolean control signals from a specification given as a quantified first-order formula (with a specific quantifier structure). Our approach uses uninterpreted functions to abstract details of the design. We construct an unsatisfiable SMT formula from the given specification. Then, from just one proof of unsatisfiability, we use a variant of Craig interpolation to compute multiple coordinated interpolants that implement the Boolean control signals. Our method avoids iterative learning and back-substitution of the control functions. We applied our approach to synthesize a controller for a simple two-stage pipelined processor, and present first experimental results."}],"_id":"1385","publist_id":"5825","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","ec_funded":1,"title":"Synthesizing multiple boolean functions using interpolation on a single proof","quality_controlled":"1","year":"2013","date_created":"2018-12-11T11:51:43Z","citation":{"ista":"Hofferek G, Gupta A, Könighofer B, Jiang J, Bloem R. 2013.

In several applications, most notably synthesis, the future is diverse or unknown, leading to algorithms that are based on deterministic automata. Hoping to retain some of the advantages of nondeterministic automata, researchers have studied restricted classes of nondeterministic automata. Three such classes are nondeterministic automata that are good for trees (GFT; i.e., ones that can be expanded to tree automata accepting the derived tree languages, thus whose choices should satisfy diverse futures), good for games (GFG; i.e., ones whose choices depend only on the past), and determinizable by pruning (DBP; i.e., ones that embody equivalent deterministic automata). The theoretical properties and relative merits of the different classes are still open, having vagueness on whether they really differ from deterministic automata. In particular, while DBP ⊆ GFG ⊆ GFT, it is not known whether every GFT automaton is GFG and whether every GFG automaton is DBP. Also open is the possible succinctness of GFG and GFT automata compared to deterministic automata. We study these problems for ω-regular automata with all common acceptance conditions. We show that GFT=GFG⊃DBP, and describe a determinization construction for GFG automata.","lang":"eng"}],"intvolume":"      7966","publist_id":"5823","ec_funded":1,"title":"Nondeterminism in the presence of a diverse or unknown future","file_date_updated":"2020-07-14T12:44:48Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","year":"2013","date_created":"2018-12-11T11:51:44Z","quality_controlled":"1","oa":1,"citation":{"mla":"Boker, Udi, et al. <i>Nondeterminism in the Presence of a Diverse or Unknown Future</i>.

The geometric phase is determined only by the shape of this path and is, in its simplest form, a real number. However, if the system has degenerate energy levels, then matrix-valued geometric state transformations, known as non-Abelian holonomies-the effect of which depends on the order of two consecutive paths-can be obtained. They are important, for example, for the creation of synthetic gauge fields in cold atomic gases or the description of non-Abelian anyon statistics. Moreover, there are proposals to exploit non-Abelian holonomic gates for the purposes of noise-resilient quantum computation. In contrast to Abelian geometric operations, non-Abelian ones have been observed only in nuclear quadrupole resonance experiments with a large number of spins, and without full characterization of the geometric process and its non-commutative nature. Here we realize non-Abelian non-adiabatic holonomic quantum operations on a single, superconducting, artificial three-level atom by applying a well-controlled, two-tone microwave drive. Using quantum process tomography, we determine fidelities of the resulting non-commuting gates that exceed 95 per cent. We show that two different quantum gates, originating from two distinct paths in Hilbert space, yield non-equivalent transformations when applied in different orders. This provides evidence for the non-Abelian character of the implemented holonomic quantum operations. In combination with a non-trivial two-quantum-bit gate, our method suggests a way to universal holonomic quantum computing."}],"author":[{"last_name":"Abdumalikov","full_name":"Abdumalikov, Abdufarrukh A","first_name":"Abdufarrukh"},{"id":"4B591CBA-F248-11E8-B48F-1D18A9856A87","full_name":"Johannes Fink","last_name":"Fink","first_name":"Johannes M","orcid":"0000-0001-8112-028X"},{"first_name":"K","last_name":"Juliusson","full_name":"Juliusson, K"},{"full_name":"Pechal, M","last_name":"Pechal","first_name":"M"},{"first_name":"Stefan","last_name":"Berger","full_name":"Berger, Stefan T"},{"last_name":"Wallraff","full_name":"Wallraff, Andreas","first_name":"Andreas"},{"first_name":"Stefan","last_name":"Filipp","full_name":"Filipp, Stefan"}],"publication_status":"published","date_published":"2013-04-25T00:00:00Z","page":"482 - 485","day":"25","volume":496,"type":"journal_article","month":"04","publisher":"Nature Publishing Group","issue":"7446","extern":1,"publication":"Nature","acknowledgement":"This work is supported financially by GEOMDISS, the Swiss National Science Foundation and ETH Zurich","citation":{"apa":"Abdumalikov, A., Fink, J.

Transport in these junctions is primarily through an unoccupied molecular orbital that is partly hybridized with the Au, which results in splitting the degeneracy of the lowest unoccupied molecular orbital triplet. The transmission through these junctions, however, cannot be modeled by a single Lorentzian resonance, as our results show evidence of quantum interference between an occupied and an unoccupied orbital.

Our design for molecular rectifiers uses a symmetric, conjugated molecular backbone with a single methylsulfide group linking one end to a gold electrode and a covalent gold–carbon bond at the other end. The gold–carbon bond results in a hybrid gold-molecule “gateway” state pinned close to the Fermi level of one electrode. Through nonequilibrium transport calculations, we show that the energy of this state shifts drastically with applied bias, resulting in rectification at surprisingly low voltages. We use this concept to design and synthesize a family of diodes and demonstrate through single-molecule current–voltage measurements that the rectification ratio can be predictably and efficiently tuned. This result constitutes the first experimental demonstration of a rationally tunable system of single-molecule rectifiers. More generally, the results demonstrate that the high-bias properties of “gateway” states can be used to provide additional functionality to molecular electronic systems."}],"pmid":1,"status":"public","extern":"1","publication":"Nano Letters","issue":"12","publisher":"American Chemical Society","OA_type":"closed access","article_processing_charge":"No","type":"journal_article","volume":13,"page":"6233-6237","day":"25","date_created":"2024-09-09T11:29:47Z","year":"2013","quality_controlled":"1","article_type":"letter_note","citation":{"ieee":"A.

Here, we show how core-hole clock spectroscopy can be used to measure charge transfer through noncovalent interactions. We study the model system 1,4-benzenediamine molecules bound on an Au surface through an Au–N donor–acceptor bond as these are known to provide a pathway for electronic conduction in molecular devices. We study different phases of the molecule/Au system and map charge delocalization times from carbon and nitrogen sites on the molecule. We show that charge delocalization across Au–N donor–acceptor bond occurs in less than 500 as. Furthermore, the Au–N bond also enhances delocalization times from neighboring carbon sites, demonstrating that fast charge transfer across a metal–organic interface does not require a covalently bonded system.","lang":"eng"}],"doi":"10.1021/jp405229b","publication_identifier":{"eissn":["1932-7455"],"issn":["1932-7447"]},"language":[{"iso":"eng"}],"oa_version":"None","scopus_import":"1","month":"07","author":[{"full_name":"Kladnik, Gregor","last_name":"Kladnik","first_name":"Gregor"},{"full_name":"Cvetko, Dean","last_name":"Cvetko","first_name":"Dean"},{"last_name":"Batra","full_name":"Batra, Arunabh","first_name":"Arunabh"},{"last_name":"Dell’Angela","full_name":"Dell’Angela, Martina","first_name":"Martina"},{"full_name":"Cossaro, Albano","last_name":"Cossaro","first_name":"Albano"},{"full_name":"Kamenetska, Maria","last_name":"Kamenetska","first_name":"Maria"},{"last_name":"Venkataraman","id":"9ebb78a5-cc0d-11ee-8322-fae086a32caf","full_name":"Venkataraman, Latha","orcid":"0000-0002-6957-6089","first_name":"Latha"},{"first_name":"Alberto","full_name":"Morgante, Alberto","last_name":"Morgante"}],"date_published":"2013-07-17T00:00:00Z","date_updated":"2025-01-03T07:59:05Z"},{"title":"Impact of molecular symmetry on single-molecule conductance","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","year":"2013","date_created":"2024-09-09T11:32:00Z","article_type":"letter_note","quality_controlled":"1","citation":{"chicago":"Dell, Emma J., Brian Capozzi, Kateri H.

We find a broad distribution in the single-molecule conductance of bithiophene compared with that of a methyl sulfide terminated biphenyl. Using a combination of experiments and calculations, we show that this increased breadth in the conductance distribution is explained by the difference in 5-fold symmetry of thiophene rings as compared to the 6-fold symmetry of benzene rings. The reduced symmetry of thiophene rings results in a restriction on the torsion angle space available to these molecules when bound between two metal electrodes in a junction, causing each molecular junction to sample a different set of conformers in the conductance measurements. In contrast, the rotations of biphenyl are essentially unimpeded by junction binding, allowing each molecular junction to sample similar conformers. This work demonstrates that the conductance of bithiophene displays a strong dependence on the conformational fluctuations accessible within a given junction configuration, and that the symmetry of such small molecules can significantly influence their conductance behaviors."}],"doi":"10.1021/ja4055367","publication_identifier":{"issn":["0002-7863"],"eissn":["1520-5126"]},"language":[{"iso":"eng"}],"external_id":{"arxiv":["23905714"]},"month":"08","oa_version":"None","scopus_import":"1","date_published":"2013-08-01T00:00:00Z","author":[{"last_name":"Dell","full_name":"Dell, Emma J.","first_name":"Emma J."},{"last_name":"Capozzi","full_name":"Capozzi, Brian","first_name":"Brian"},{"first_name":"Kateri H.","full_name":"DuBay, Kateri H.","last_name":"DuBay"},{"first_name":"Timothy C.","last_name":"Berkelbach","full_name":"Berkelbach, Timothy C."},{"first_name":"Jose Ricardo","full_name":"Moreno, Jose Ricardo","last_name":"Moreno"},{"full_name":"Reichman, David R.","last_name":"Reichman","first_name":"David R."},{"last_name":"Venkataraman","id":"9ebb78a5-cc0d-11ee-8322-fae086a32caf","full_name":"Venkataraman, Latha","first_name":"Latha","orcid":"0000-0002-6957-6089"},{"full_name":"Campos, Luis M.","last_name":"Campos","first_name":"Luis M."}],"date_updated":"2025-01-03T08:00:57Z"},{"page":"3358-3364","day":"03","volume":13,"type":"journal_article","article_processing_charge":"No","OA_type":"closed access","publisher":"American Chemical Society","issue":"7","publication":"Nano Letters","extern":"1","status":"public","_id":"17996","intvolume":"        13","abstract":[{"text":"We compare the conductance of a series of amine-terminated oligophenyl and alkane molecular junctions formed with Ag and Au electrodes using the scanning tunneling microscope based break-junction technique.

The measured conductance decays exponentially with molecular backbone length with a decay constant that is essentially the same for Ag and Au electrodes. However, the formation and evolution of molecular junctions upon elongation are very different for these two metals. Specifically, junctions formed with Ag electrodes sustain significantly longer elongation when compared with Au due to a difference in the initial gap opened up when the metal point-contact is broken.

We observe the formation of contacts with a conductance close to 1 G0, the quantum of conductance, which can be attributed to a single-atom contact, similar to those formed by Au. We also find two additional conductance features at ∼0.4 G0 and ∼1.3 G0, which have been previously ascribed to contacts with oxygen contaminations. Here, using a conductance cross-correlation technique, we distinguish three different atomic-scale structural motifs and analyze their rupture forces and stiffness. Our results allow us to assign the ∼0.4 G0 conductance feature to an Ag–O–Ag contact and the ∼1.3 G0 feature to an Ag–Ag single-atom contact with an oxygen atom in parallel. Utilizing complementary information from force and conductance, we thus demonstrate the correlation of conductance with the structural evolution at the atomic scale.","lang":"eng"}],"intvolume":"         7","pmid":1,"publication_status":"published","publication_identifier":{"eissn":["1936-086X"],"issn":["1936-0851"]},"doi":"10.1021/nn4007187","scopus_import":"1","oa_version":"None","month":"03","external_id":{"pmid":["23521342"]},"language":[{"iso":"eng"}],"date_updated":"2025-01-03T08:07:54Z","author":[{"first_name":"Sriharsha V.","last_name":"Aradhya","full_name":"Aradhya, Sriharsha V."},{"first_name":"Michael","full_name":"Frei, Michael","last_name":"Frei"},{"last_name":"Halbritter","full_name":"Halbritter, András","first_name":"András"},{"id":"9ebb78a5-cc0d-11ee-8322-fae086a32caf","last_name":"Venkataraman","full_name":"Venkataraman, Latha","orcid":"0000-0002-6957-6089","first_name":"Latha"}],"date_published":"2013-03-23T00:00:00Z"},{"title":"Single-molecule junctions beyond electronic transport","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"ieee":"S.

Among these, single-molecule junctions in a metal–molecule–metal motif have contributed significantly to our fundamental understanding of the principles required to realize molecular-scale electronic components from resistive wires to reversible switches. The success of these techniques and the growing interest of other disciplines in single-molecule-level characterization are prompting new approaches to investigate metal–molecule–metal junctions with multiple probes. Going beyond electronic transport characterization, these new studies are highlighting both the fundamental and applied aspects of mechanical, optical and thermoelectric properties at the atomic and molecular scales. Furthermore, experimental demonstrations of quantum interference and manipulation of electronic and nuclear spins in single-molecule circuits are heralding new device concepts with no classical analogues. In this Review, we present the emerging methods being used to interrogate multiple properties in single molecule-based devices, detail how these measurements have advanced our understanding of the structure–function relationships in molecular junctions, and discuss the potential for future research and applications.","lang":"eng"}],"publication_status":"published","publication_identifier":{"issn":["1748-3387"],"eissn":["1748-3395"]},"doi":"10.1038/nnano.2013.91","month":"06","oa_version":"None","scopus_import":"1","language":[{"iso":"eng"}],"external_id":{"pmid":["23736215"]},"date_updated":"2025-01-03T08:10:06Z","date_published":"2013-06-01T00:00:00Z","author":[{"first_name":"Sriharsha V.","last_name":"Aradhya","full_name":"Aradhya, Sriharsha V."},{"orcid":"0000-0002-6957-6089","first_name":"Latha","full_name":"Venkataraman, Latha","last_name":"Venkataraman","id":"9ebb78a5-cc0d-11ee-8322-fae086a32caf"}]},{"publication_status":"published","place":"Berlin, Heidelberg","author":[{"full_name":"Rosman, Guy","last_name":"Rosman","first_name":"Guy"},{"last_name":"Bronstein","full_name":"Bronstein, Michael M.","first_name":"Michael M."},{"last_name":"Bronstein","full_name":"Bronstein, Alexander","id":"58f3726e-7cba-11ef-ad8b-e6e8cb3904e6","first_name":"Alexander","orcid":"0000-0001-9699-8730"},{"full_name":"Wolf, Alon","last_name":"Wolf","first_name":"Alon"},{"last_name":"Kimmel","full_name":"Kimmel, Ron","first_name":"Ron"}],"date_published":"2013-04-04T00:00:00Z","alternative_title":["Mathematics and Visualization"],"_id":"18351","abstract":[{"lang":"eng","text":"Motion-based segmentation is an important tool for the analysis of articulated shapes. As such, it plays an important role in mechanical engineering, computer graphics, and computer vision. In this chapter, we study motion-based segmentation of 3D articulated shapes. We formulate motion-based surface segmentation as a piecewise-smooth regularization problem for the transformations between several poses. Using Lie-group representation for the transformation at each surface point, we obtain a simple regularized fitting problem. An Ambrosio-Tortorelli scheme of a generalized Mumford-Shah model gives us the segmentation functional without assuming prior knowledge on the number of parts or even the articulated nature of the object.
