Importance of closed quark loops for lattice QCD studies of tetraquarks
Joshua Berlin, Abdou Abdel-Rehim, Constantia Alexandrou +5
To investigate the light scalar tetraquark candidate (quantum numbers ), a correlation matrix including a variety of two- and four-quark interpolating operator…
Plasmon properties and hybridization effects in Silicene
C. Vacacela Gomez, M. Pisarra, M. Gravina +2
The plasmonic character of monolayer silicene is investigated by time-dependent density functional theory in the random phase approximation. The energy-loss function of the system…
Plasmon modes of graphene nanoribbons with periodic planar arrangements
Cristian Vacacela Gomes, Michele Pisarra, Mario Gravina +2
Among their amazing properties, graphene and related low-dimensional materials show quantized charge-density fluctuations--known as plasmons--when exposed to photons or electrons o…
Computation of correlation matrices for tetraquark candidates with and flavor structure
Joshua Berlin, Abdou Abdel-Rehim, Constantia Alexandrou +3
The conjecture that several recently observed mesons have a structure, which is not dominated by an ordinary quark-antiquark pair, but by a four-quark structure, is being actively…
Investigation of the tetraquark candidate : technical aspects and preliminary results
Abdou Abdel-Rehim, Constantia Alexandrou, Joshua Berlin +3
We discuss technical aspects and first results of a lattice QCD study of the state. We employ various interpolating operators of quark-antiquark, mesonic molecule, diqua…
Critical behavior and continuum scaling of lattice gauge theories
Oleg Borisenko, Volodymyr Chelnokov, Mario Gravina +1
Three-dimensional lattice gauge theories are studied numerically at finite temperature for = 5, 6, 8, 12, 13, 20 and for =2,4,8. For each model the location of phas…
