High-frequency contactless characterization of 2D materials. Graphene, WS2
(2020-12)
Article
Restricted access - publisher's policyThe electrical conductivity of two-dimensional (2D) materials without any electrical contact can be obtained using two different methods: the terahertz time domain spectroscopy (THz-TDS) method, in the range from GHz up ... -
Detecting topology through dynamics in interacting fermionic wires
(American Physical Society, 2020-08-05)
Article
Open AccessProbing the topological invariants of interacting systems stands as a grand and open challenge. Here we describe a dynamical method to characterize 1D chiral models, based on the direct observation of time-evolving bulk ... -
Two-dimensional topological quantum walks in the momentum space of structured light
(Optical Society of American (OSA), 2020-02-20)
Article
Open AccessQuantum walks are powerful tools for quantum applications and for designing topological systems. Although they are simulated in a variety of platforms, genuine two-dimensional realizations are still challenging. Here we ... -
Beyond Lee-Huang-Yang description of self-bound Bose mixtures
(2020-08-18)
Article
Open AccessWe investigate the properties of self-bound ultradilute Bose-Bose mixtures, beyond the Lee-Huang-Yang description. Our approach is based on the determination of the beyond mean-field corrections to the phonon modes of the ... -
Solvation dynamics in water: 4: on the initial regime of solvation relaxation
(2020-09-03)
Article
Restricted access - publisher's policyIt is shown, by means of numerical and analytic work, that initial molecular momenta play little significant role in the initial fast solvation relaxation that follows electronic excitation of, and charge creation for, a ... -
Influence of cholesterol on the orientation of the farnesylated GTP-bound KRas-4B binding with anionic model membranes
(Multidisciplinary Digital Publishing Institute (MDPI), 2020-11-22)
Article
Open AccessThe Ras family of proteins is tethered to the inner leaflet of the cell membranes which plays an essential role in signal transduction pathways that promote cellular proliferation, survival, growth, and differentiation. ... -
Long-lasting salt bridges provide the anchoring mechanism of oncogenic kirsten rat sarcoma proteins at cell membranes
(2020-11-10)
Article
Restricted access - publisher's policyRAS proteins work as GDP-GTP binary switches and regulate cytoplasmic signaling networks that are able to control several cellular processes, playing an essential role in signal transduction pathways involved in cell growth, ... -
Few-body bound states of two-dimensional bosons
(American Physical Society (APS), 2020-04-07)
Article
Open AccessWe study clusters of the type $A_NB_M$ with N=M=3 in a two-dimensional mixture of A and B bosons, with attractive AB and equally repulsive AA and BB interactions. In order to check universal aspects of the problem, we ... -
The dynamics of digits: calculating Pi with Galperin's billiards
(Multidisciplinary Digital Publishing Institute (MDPI), 2020-04-01)
Article
Open AccessIn Galperin billiards, two balls colliding with a hard wall form an analog calculator for the digits of the number p . This classical, one-dimensional three-body system (counting the hard wall) calculates the digits of p ... -
Efficient recursive Adams–Bashforth methods in molecular dynamics simulations of N-body systems interacting through pairwise potentials
(2020-09-09)
Article
Restricted access - publisher's policyA recursive multistep Adams–Bashforth method applied to the Molecular Dynamics simulations of N-body systems interacting through pairwise force fields is introduced and analysed. Equations of motion are obtained using a ... -
Solvation structure and dynamics of the dimethylammonium cation diluted in liquid water: a molecular dynamics approach
(American Institute of Physics (AIP), 2020-06-21)
Article
Restricted access - publisher's policyClassical molecular dynamics simulation techniques were employed to investigate the local solvation structure and related dynamics of the dimethylammonium cation diluted in liquid water at ambient conditions. The translational ... -
Superfluid and supersolid phases of He-4 on the second layer of graphite
(American Institute of Physics (AIP), 2020-05-22)
Article
Open AccessWe revisited the phase diagram of the second layer of 4He on top of graphite using quantum Monte Carlo methods. Our aim was to explore the existence of the novel phases suggested recently in experimental works, and determine ...
