MSc Computer Science (University of Málaga, 1992), MSc Physics (UNED, 1993), PhD Mathematics (University of Málaga, 1998). Associate professor of computer science and artificial intelligence at the faculty of engineering of the University of Málaga. His research interests are applied mathematics and computational physics with a focus on non linear waves.

Everyone has heard the sound of the crack of a whip, at least in movies or TV serials like “El Zorro: The man with the whip” (1954). A shock wave is created by the supersonic motion of the […]

Science news with bad titles usually attract a lot of attention. A recent example is “The sound of an atom has been captured” ]. Laypeople must know that atoms do not emit sound. Quantum acoustics study the propagation and […]

The most widely used metaphors for nuclear fusion reactors are the recreation of the Sun on Earth and the controlled explosion of a hydrogen bomb. In both cases, the first thing that comes to mind is the need for high-performance […]

Human brain has about 85 billion neurons. Each neuron forms thousands of chemical and electrical synapses with other neurons. To record the synaptic activity of each neuron in the brain an intracellular probe with a millivolt scale is required. Glass […]

Entanglement is a fundamental tool in quantum computing and several quantum information protocols, such as quantum teleportation, quantum cryptography and quantum key distribution. The basic unit of entanglement is the entangled bit (ebit), represented by a maximally entangled […]

Without any conflict with the second law of thermodynamics, heat can flow from a cooler but constantly heated body to another thermally connected and constantly hotter body. This anomalous heat transfer has been demonstrated in a two-phase liquid-vapor system composed […]

Pele is the Hawaiian goddess of volcanoes. Pele’s hairs are thin strands of molten basaltic glass drawn out from lava, thrown into the air from lava fountains, lava cascades or vigorous lava flows, and spun out by the wind. […]

Newton’s theory of gravitation assumes that the speed of gravity is infinite and the gravitational interaction is instantaneous. However, Einstein’s theory postulates that it is exactly equal to the speed of light. A team of Chinese physicists lead by Tang […]

Where is the half of the ordinary matter in the universe not observed yet? Computer simulations of cosmological galaxy formation predict the existence of large intercluster filaments of hot and low-density gas, the so-called cosmic web. For the first time, […]
