Topological aspects of string theories
Nuclear Physics B, 1987 In previous work, a new action principle for strings and superstrings in arbitrary dimensions was developed. It led to a classification of strings similar to the classification of point particles as massive, massless and tachyonic. Topological aspects of four-dimensional strings were also investigated.

Topological Defects in QCD at large Baryon Density and/or large $N_c$
, 2005 The main leitmotiv of the present talk is analysis of different topological objects such as strings and domain walls in QCD. As it is well known, the standard model in general (and QCD in particular) does not support any kind of such objects due to some ...

Advanced Quantum Technologies, EarlyView.The hybrid approach to Quantum Supervised Machine Learning is compatible with Noisy Intermediate Scale Quantum (NISQ) devices but hardly useful. Pure quantum kernels requiring fault‐tolerant quantum computers are more promising. Examples are kernels computed by means of the Quantum Fourier Transform (QFT) and kernels defined via the calculation of ...

B-strings on non-Kählerian manifolds
Nuclear Physics B, 2016 We explain how to couple topological B-models whose targets are non-Kählerian manifolds to topological gravity and to thus define corresponding topological strings.

What can we Learn from Quantum Convolutional Neural Networks?
Advanced Quantum Technologies, EarlyView.Quantum Convolutional Neural Networks have been long touted as one of the premium architectures for quantum machine learning (QML). But what exactly makes them so successful for tasks involving quantum data? This study unlocks some of these mysteries; particularly highlighting how quantum data embedding provides a basis for superior performance in ...

arXiv, 2003 A virtual string is a scheme of self-intersections of a closed curve on a surface. We introduce virtual strings and study their geometric properties and homotopy invariants. We also discuss connections between virtual strings, Gauss words, and virtual knots.

Drum vortons in high density QCD [PDF]
, 2002 Recently it was shown that high density QCD supports of number of topological defects. In particular, there are U(1)_Y strings that arise due to K^0 condensation that occurs when the strange quark mass is relatively large.

Nanoparticle Skin Penetration: Depths and Routes Modeled In‐Silico
Small, EarlyView.An in‐silico human skin model based on 20 years of NP penetration studies, incorporating 19 parameters is developed. Using random forest and Kennard‐Stone sorting, the model achieves 95% accuracy, identifying hair follicle diameter as the dominant penetration factor.

Instantons, Topological Strings, and Enumerative Geometry
Advances in Mathematical Physics, 2010 We review and elaborate on certain aspects of the connections between instanton counting in maximally supersymmetric gauge theories and the computation of enumerative invariants of smooth varieties. We study in detail three instances of gauge theories in
