ICTP - Seminars

Seminars

CMSP seminars are usually held on Wednesdays at 16:00 in the Luigi Stasi Seminar Room (Leonardo Building, first floor).

Informal seminars may also take place on Tuesdays and Thursdays in the Luigi Stasi Seminar Room at 11:30 a.m.

Joint ICTP/SISSA Statistical Physics Seminars are organized jointly by the CMSP group of ICTP and the Statistical Physics Section at SISSA. The seminars take place either at ICTP or SISSA, alternately on Tuesday mornings.

All seminars are announced on the CMSP information board located in the Leonardo Building, second floor, near the CMSP Secretariat.

Also, check the announcements on ICTP notice boards regularly for seminar updates.

Condensed Matter Seminar: Interplay of Charge and Spin Degrees of Freedom in Pnictides and Dichalcogenides

Room: Leonardo Building - Luigi Stasi Seminar Room

Speaker(s): Dmitry EFREMOV (IFW, Dresden, Germany)

Seminar Start Time: 11:00

Europe/Rome Abstract: Consider a quantum chain in its ground state and then take a subdomain of this system with natural truncated hamiltonian. Since the total hamiltonian does not commute with the truncated hamiltonian the subsystem can be in one of its eigenenergies with different probabilities. Since the global energy eigenstates are locally close to diagonal in the local energy eigenbasis we argue that the Shannon(Renyi) entropy of these probabilities follows an area-law for the gapped systems. When the system is at the critical point the Shannon(Renyi) entropy follows a logarithmic behaviour with a universal coefficient. Our results show that the Shannon(Renyi) entropy of the subsystem energies closely mimics the behaviour of the entanglement entropy in quantum chains. We support the arguments by detailed numerical calculations performed on the transverse field XY-chain. ICTP ICTP pio@ictp.it

Joint ICTP/SISSA Statistical Physics Seminar: Area-Law and Universality in the Statistics of the Subsystem Energy

Room: Leonardo Building - Luigi Stasi Seminar Room

Speaker(s): Mohammad Ali RAJABPOUR (Instituto de Fisica, Univ. Federal Fluminense, Niteroi, Brazil)

Seminar Start Time: 11:00

Europe/Rome Complex networks describe the architecture of complex systems ranging from the brain to social networks. Recently it has become clear that in order to understand network data it is important characterize network structures with advanced topological and geometrical approaches. Here we discuss a model for emergent hyperbolic geometry called 'Network Geometry with Flavor' that describes complex growing simplicial complexes and extend previous modelling framework on growing complex networks. We will present the holographic properties of this model and its intrinsic complex network structure. Finally we will discuss the mapping between the Network Geometry with Flavor and Tree Tensor Networks and we will comment on the open recent questions that this mapping raises for modelling Complex Quantum Networks.

ICTP Seminar Series in Condensed Matter and Statistical Physics: From Complex Networks to Tensor Networks: A Journey through Network Geometry with Flavor

Room: Leonardo Building - Luigi Stasi Seminar Room

Speaker(s): Ginestra BIANCONI (School of Mathematical Sciences, Queen Mary University of London, U.K.)

Seminar Start Time: 11:00

Europe/Rome Electrocatalytic conversion of biomass derived feedstocks offers a promising avenue for effective carbon recycling from renewable energy resources. To retain economic viability of this target technology, rational design of electrocatalysts with high activity and selectivity towards producing value-added chemicals and fuels is necessary. For improved conversion of biomass resources to fuels and fine chemicals, understanding and controlling the aqueous-phase catalytic hydrogenation of organic compounds on metals is crucial. Unlike gas-phase hydrogenation, the presence of water and the solid/liquid interface play critical roles in catalysis. Although there have been extensive studies in electrocatalysis, there exists a lack of mechanistic exploration and molecular-level understanding of electrocatalytic conversion of organic compounds specifically pertaining to biomass feedstocks. Moreover, these reactions occur at the solvated electrode-electrolyte interface where complex interactions between the electrode and solvent molecules have a critical influence on the reaction chemistry. In this talk, I will address the effect of the solvent and the charged metal electrode on the reaction pathways and their capacity to undergo reduction/hydrogenation. Results of molecular-scale structural/electronic properties near the electrochemical interface and the reaction energetics of target organic compounds obtained from density-functional-theory(DFT) based ab initio molecular dynamics (AIMD) simulations will be presented. The inferences drawn will be used to postulate design criteria for electrocatalytic conversion of organic compounds from an experimental and theoretical perspective. ICTP ICTP pio@ictp.it
