Nonlocal Electrostatic Field Theory from Microscopic Description
Varazdat Stepanyan, Yevgeni Sh. Mamasakhlisov, Armen E. Allahverdyan
The study of electric fields in soft materials converges either to the study of point-like particles (local) in nonlinear theories or to the use of particles with finite sizes in n…
Common causes for quantum identical particles
A. Hovhannisyan, S. Weigert, A. E. Allahverdyan
Violations of Bell's inequalities imply that joint probabilities generated by non-commutative measurements on two (non-identical) quantum particles do not have a single common caus…
Classical dissipative search of unstructured database
A. E. Allahverdyan, Y. Bisharyan
We propose a physical realization of the unstructured database search that works via classical, dissipative model of spherical spins. The database is implemented via spin-spin coup…
Resonances in light scattering from nonequilibrium dipole pairs
Vanik E. Mkrtchian, Armen E. Allahverdyan, Mikayel Khanbekyan
We identify a fundamentally new class of resonances in light scattering from a pair of point-like electric dipoles. These resonances arise from multiple scattering response and cor…
System-Bath Approach to Rotating Brownian Motion
Ashot Matevosyan, Armen E. Allahverdyan
Rotating equilibrated systems are widespread, but relatively little attention has been devoted to studying them from the first principles of statistical mechanics. We fill this gap…
Nonnegative matrix factorization and the principle of the common cause
E. Khalafyan, A. E. Allahverdyan, A. Hovhannisyan
Nonnegative matrix factorization (NMF) is a known unsupervised data-reduction method. The principle of the common cause (PCC) is a basic methodological approach in probabilistic ca…
