  • Mode-cleaning in antisymmetrically modulated non-Hermitian waveguides 

    Akhter, Mohammad Nayeem; Botey Cumella, Muriel; Herrero Simon, Ramon; Staliunas, Kestutis (2024-01-12)
    Article
    Accés obert
    We demonstrate all-optical spatial mode-cleaning in non-Hermitian waveguides. The effect is accounted by a unidirectional coupling among the modes resulting from a simultaneous modulation of the refractive index and the ...
  • On the dynamics of the turbulent flow past a three-element wing 

    Montalà Sales, Ricard; Lehmkuhl Barba, Oriol; Rodríguez Pérez, Ivette María (American Institute of Physics (AIP), 2024-02)
    Article
    Accés obert
    A comprehensive analysis of the unsteady flow dynamics past the 30P30N three-element high lift wing is performed by means of large eddy simulations at different angles of attack (a¿=¿5°, 9°, and 23°) and at a Reynolds ...
  • Stabilization of microlasers by non-Hermitian potentials 

    Herrero Simon, Ramon; Botey Cumella, Muriel; Benadouda Ivars, Salim; Akhter, Mohammad Nayeem; Staliunas, Kestutis (International Society for Photo-Optical Instrumentation Engineers (SPIE), 2023)
    Text en actes de congrés
    Accés obert
    Vertical-cavity semiconductor lasers as well as single units or arrays of Edge Emitting Lasers suffer from dynamical spatiotemporal instabilities leading to temporally unstable and low spatial beam quality. We propose a ...
  • Dielectric spectroscopy studies of conformational relaxation dynamics in molecular glass-forming liquids 

    Romanini, Michela; Macovez, Roberto; Valenti, Sofia; Noor, Wahi; Tamarit Mur, José Luis (Multidisciplinary Digital Publishing Institute (MDPI), 2023-12-06)
    Article
    Accés obert
    We review experimental results obtained with broadband dielectric spectroscopy concerning the relaxation times and activation energies of intramolecular conformational relaxation processes in small-molecule glass-formers. ...
  • In silico drug derivatives for KRAS-G12D: free-energy surfaces in aqueous solution by well-tempered metadynamics simulations 

    Hu, Zheyao; Martí Rabassa, Jordi (2024-02-15)
    Article
    Accés restringit per política de l'editorial
    KRAS oncogenes are the largest family of mutated RAS isoforms, participating in about 30% of all cancers. Due to their paramount medical importance, enormous effort is being devoted to the development of inhibitors using ...
  • Connection between mechanical relaxation and equilibration kinetics in a high-entropy metallic glass 

    Duan, Yajuan; Nabahat, Mehran; Tong, Yu; Ortiz Membrado, Laia; Jiménez Piqué, Emilio; Zhao, Kun; Wang, Yun-Jiang; Yang, Yong; Wada, Takeshi; Kato, Hidemi; Pelletier, J. M.; Qiao, Jichao; Pineda Soler, Eloi (American Institute of Physics (AIP), 2024-02-02)
    Article
    Accés obert
    The slow transition from an out-of-equilibrium glass towards a supercooled liquid is a complex relaxation phenomenon. In this Letter, we study the correlation between mechanical relaxation and equilibration kinetics in a ...

    Montalà Sales, Ricard; Lehmkuhl Barba, Oriol; Rodríguez Pérez, Ivette María (2024-02-12)
    Article
    Accés obert
    A comprehensive analysis of the unsteady flow dynamics past the 30P30N three-element high lift wing is performed by means of large eddy simulations at different angles of attack (AoA=5°, 9°, and 23°) and at a Reynolds ...
  • DNS and POD analysis of separated flow in a three-dimensional diffuser 

    Miró Jané, Arnau; Eiximeno Franch, Benet; Rodríguez Pérez, Ivette María; Lehmkuhl Barba, Oriol (Springer, 2023)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    A DNS of a three dimensional diffuser has been performed with the in-house solver Alya. The resulting dataset presents a good agreement with existing numerical and experimental data, even without smoothing of the sharp ...
  • Permutation entropy-based characterization of speckle patterns generated by semiconductor laser light 

    Tirabassi, Giulio; Duque Gijón, María; Tiana Alsina, Jordi; Masoller Alonso, Cristina (2023-12)
    Article
    Accés obert
    Semiconductor lasers with optical feedback are stochastic nonlinear systems that can display complex dynamics and abrupt changes when their operation conditions change. Even very small changes can lead to large variations ...
  • Henry's constant of helium in liquid alkali metals 

    Álvarez Galera, Edgar; Laria, Daniel; Batet Miracle, Lluís; Martí Rabassa, Jordi (2024-02)
    Article
    Accés obert
    The determination of the solubility of helium in liquid lithium and in lead-lithium eutectic systems is of crucial importance for the assessment of the reliability, safety and efficiency of future nuclear reactor plants ...
  • In silico design of a lipid-like compound targeting KRAS4B-G12D through non-covalent bonds 

    Lu, Huixia; Hu, Zheyao; Faraudo, Jordi; Martí Rabassa, Jordi (2023-11-21)
    Article
    Accés obert
    One of the most common drivers in human cancer is the peripheral membrane protein KRAS4B, able to promote oncogenic signalling. To signal, oncogenic KRAS4B not only requires a sufficient nucleotide exchange, but also needs ...
  • Lyapunov exponents and extensivity of strongly coupled chaotic maps in regular graphs 

    Gancio Vázquez, Juan; Rubido, Nicolas (Elsevier, 2024-01-01)
    Article
    Accés obert
    n Thermodynamics and Statistical Physics, a system’s property is extensive when it grows with the system size. When it happens, the system can be decomposed into separate components, which has been done in many systems ...
