  The KM3NeT research infrastructure in the Mediterranean is a multi-purpose cubic-kilometre neutrino observatory consisting of two detectors optimised to study cosmic and atmospheric neutrinos between GeV to PeV energies. ...
• Dynamic higher-order Bessel-Gauss beam interference generation of rotating beams 

  Kontenis, Gabrielius; Gailevicius, Darius; Jiménez, Noé; Staliunas, Kestutis (International Society for Photo-Optical Instrumentation Engineers (SPIE), 2022)
  Conference report
  Restricted access - publisher's policy

  One of the key trends in laser material processing is the usage of structured laser beams. One such example is the Bessel beam with an elongated focal area and self-healing properties. Higher-order Bessel beams can be ...
• Spatial filter realized by dielectrice waveguides 

  Lukošiunas, Ignas; Gailevicius, Darius; Staliunas, Kestutis (International Society for Photo-Optical Instrumentation Engineers (SPIE), 2022)
  Conference report
  Restricted access - publisher's policy

  In this work, we introduce a spatial filtering mechanism that can be effectively utilized by photonic crystals. The phenomenon utterly expressed here is Rayleigh-Wood’s anomaly. Such a mechanism is realized and optimized ...
• Modes in microchip lasers 

  Plukys, Matas; Gaizauskas, Eugenijus; Gailevicius, Darius; Staliunas, Kestutis (International Society for Photo-Optical Instrumentation Engineers (SPIE), 2022)
  Conference report
  Restricted access - publisher's policy

  The transverse modes in microchip lasers (MCL) appear different from the classical mode theory, as the resonator consists of a set of plane mirrors (similar to semiconductor edge-emitting lasers and VCSELs). Then the ...

  Non-Hermitian coupled semiconductor laser array 

  Herrero Simon, Ramon; Medina Pardell, Judith; Botey Cumella, Muriel; Staliunas, Kestutis (International Society for Photo-Optical Instrumentation Engineers (SPIE), 2022)
  Conference report
  Open Access

  We propose and explore a stabilization mechanism of a semiconductor laser array based on asymmetric coupling between neighboring lasers. The stabilization scheme takes advantage of the symmetry breaking of non-Hermitian ...
• Scaling Effect in an intermediate Break LOCA scenario 

  Martin Gil, Kevin; Freixa Terradas, Jordi; Martínez Quiroga, Víctor Manuel (2022)
  Conference report
  Restricted access - publisher's policy

  Scaling studies in the field of nuclear thermalhydraulics have been carried out to analyze and extrapolate phenomenology from Integral Test Facilities (ITFs) to operating full size Nuclear Power Plants (NPP). The Power-to-Volume ...
• The Equivalency of Theoretical and Monte Carlo Approaches in Neutron Transport: the case of simplified slowing-down 

  Al Awad, Abdulrahman; Calviño Tavares, Francisco; Batet Miracle, Lluís (2022)
  Conference report
  Restricted access - publisher's policy

  For purposes of engineering education, computer experiments or simulations are powerful tools to demonstrate and emphasize physical concepts instead of relying on complex and ambiguous mathematics. The main advantage of ...
• Atomistic simulations and theoretical predictions of helium nucleation in liquid Pb-Li eutectic alloy 

  Al Awad, Abdulrahman; Batet Miracle, Lluís; Sedano Miguel, Luis Ángel (2022)
  Conference report
  Restricted access - publisher's policy

  Liquid Lead-Lithium Eutectic (LLE) alloy is a promising candidate coolant and/or breeder to attain tritium self-sufficiency in the EU DEMO breeding blanket design. Liquid metals are characterized with excellent heat-transport ...

  Direct- and Inverse-design for non-Hermitian smart light management 

  Botey Cumella, Muriel; Ahmed, Waqas W.; Herrero Simon, Ramon; Staliunas, Kestutis (META Conference, 2022)
  Conference report
  Open Access

  We present direct and inverse-design strategies to achieve ‘on demand’ dynamical manipulation of light by non-Hermitian potentials. The direct approach, based on a generalized Hilbert Transform, widens the concept of the ...

  Inverse-design of non-Hermitian potentials for light management 

  Botey Cumella, Muriel; Ahmed Waseem, Waqas Waseem; Herrero Simon, Ramon; Wu, Yina; Staliunas, Kestutis (International Society for Photo-Optical Instrumentation Engineers (SPIE), 2022)
  Conference report
  Open Access

  In this paper, we propose a general inverse-design strategy based on genetic algorithm optimization to achieve ‘on demand’ manipulation of light in one-dimensional (1D) and two-dimensional (2D) non-Hermitian systems. The ...

  Hydrogen bonding in aqueous solutions of sulfuric and methanesulfonic acids: a computer simulation study 

  Canales Gabriel, Manel; Guàrdia Manuel, Elvira (Universitat de Barcelona, 2022)
  Conference lecture
  Open Access

  One of the current research topics in atmospheric physics is the study of the influence of sulphate aerosols in the atmospheric dynamics; particularly, in the acid rain or in the greenhouse effect. In many cases these ...

  Light control by Non-Hermitian modulation in multimode fiber 

  Akhter, Mohammad Nayeem; Benadouda Ivars, Salim; Herrero Simon, Ramon; Botey Cumella, Muriel; Staliunas, Kestutis (META Conference, 2022)
  Conference report
  Open Access

  We show that a non-Hermitian modulation of the potential along the nonlinear multimode fibers controls dynamics of propagating radiation. Specifically we consider simultaneous modulation of the refraction index and gain/loss ...
