Black hole hair: twenty--five years after
Originally regarded as forbidden, black hole ``hair'' are fields associated with a stationary black hole apart from the gravitational and

Black Holes: Classical Properties, Thermodynamics and Heuristic Quantization
I discuss the no hair principle, the recently found hairy solutions, generic properties of nonvacuum spherical static black holes, and

Black Holes: Physics and Astrophysics - Stellar-mass, supermassive and primordial black holes
I present an elementary primer of black hole physics, including its general relativity basis, all peppered with astrophysical illustrations. Following

Chaotic enhancement of decay. The effect of classical phase space structure
We investigate the decay process from a time dependent potential well in the semiclassical regime. The classical dynamics is chaotic

Charge-localization and isospin-blockade in vertical double quantum dots
Charge localization seems unlikely to occur in two vertically coupled symmetric quantum dots even if a small bias voltage breaks

Conformation changes and folding of proteins mediated by Davidov's soliton
We suggest that Davidov's solitons, propagating through the backbone of a protein, can mediate conformational transition and folding of a

Continuous and discrete models of cooperation in complex bacterial colonies
We study the effect of discreteness on various models for patterning in bacterial colonies. In a bacterial colony with branching

Duality and other Exotic Gauge Dynamics in Softly Broken Supersymmetric QCD
We analyze the theory of softly broken supersymmetric $QCD$. Exotic behavior like spontaneously broken baryon number, massless composite fermions and

Modeling branching and chiral colonial patterning of lubricating bacteria
In nature, microorganisms must often cope with hostile environmental conditions. To do so they have developed sophisticated cooperative behavior and
