Exact analytic solutions of classical time crystals

Stavros Theodorakis, Athina Hadjizorzi

We present examples of classical time crystals (in a parabolic potential for the position) that admit simple exact analytic solutions. The kinetic energy in these crystals is piece…

Analytical solutions of the Schrodinger equation for the one-dimensional hydrogen molecular ion

Stavros Theodorakis

We present analytical solutions of the Schrodinger equation for the one-dimensional hydrogen molecular ion. In particular, we present closed form expressions for the electronic ene…

A variational model for the delayed collapse of Bose Einstein condensates

Stavros Theodorakis, Stavros Athanasiou

We present an action that can be used to study variationally the collapse of Bose Einstein condensates. This action is real, even though it includes dissipative terms. It adopts lo…

Nonlocal interactions in collapsing condensates in a box

Stavros Theodorakis, Nikolas Charalambous

The collapse of attractive Bose-Einstein condensates in a box with tunable interatomic interactions was studied experimentally recently. Not only were remarkably stable remnant con…

Deep density networks and uncertainty in recommender systems

Yoel Zeldes, Stavros Theodorakis, Efrat Solodnik +3

Building robust online content recommendation systems requires learning complex interactions between user preferences and content features. The field has evolved rapidly in recent…

The Wavefunction of the Collapsing Bose-Einstein Condensate

Stavros Theodorakis, Andreas Hadjigeorgiou

Bose-Einstein condensates with tunable interatomic interactions have been studied intensely in recent experiments. The investigation of the collapse of a condensate following a sud…
