The force exerted by the electrons on the nuclei of a current-carrying molecular junction can be manipulated to engineer nanoscale mechanical systems. In the adiabatic regime a peculiarity of these forces is negative friction, responsible... more
Time continuity emerges as a holographic narrative that masks Gödelian incompleteness, with non-computable observables in the bulk appearing as non-local entanglement structures on the boundary.
The Poisson-Boltzmann equation is a nonlinear elliptic equation that describes how electronic potential changes in the screening layer when a cell is immersed in an ionic solution. It is the equilibrium state formed by many charged... more
We present a comparative study of particle-hole and particle-particle channels of random-phase approximation (RPA) for molecular dissociations of different bonding types. We introduced a direct particle-particle RPA scheme, in analogy to... more
