On the problem of emergence of classical space-time: The quantum-mechanical approach [PDF]
, 2003 The classical space-time structure is derived from the structure of an abstract infinite dimensional separable Hilbert space S. For this S is first realized as a Hilbert space H* of functions of abstract parameters.

Some inequalities for the Euclidean operator radius of two operators in Hilbert spaces
, 2006 Some sharp bounds for the Euclidean operator radius of two bounded linear operators in Hilbert spaces are given. Their connection with Kittaneh’s recent results which provide sharp upper and lower bounds for the numerical radius of linear operators are ...

Advanced Electronic Materials, EarlyView.A breathable textile capacitive pressure sensor based on heterogeneous double‐sided conductive knitted fabrics and a spacer dielectric layer is developed. Structural tuning of the spacer thickness enables optimized compressibility and enhanced pressure sensitivity.

The bulk Hilbert space of double scaled SYK
Journal of High Energy Physics, 2022 The emergence of the bulk Hilbert space is a mysterious concept in holography. In [1], the SYK model was solved in the double scaling limit by summing chord diagrams.

Advanced Intelligent Discovery, EarlyView.In this study we employed support vector regressor and quantum support vector regressor to predict the hydrogen storage capacity of metal–organic frameworks using structural and physicochemical descriptors. This study presents a comparative analysis of classical support vector regression (SVR) and quantum support vector regression (QSVR) in predicting ...

(Re)Construction of Quantum Space-Time: Transcribing Hilbert into Configuration Space
EntropySpace-time in quantum mechanics is about bridging Hilbert and configuration space. Thereby, an entirely new perspective is obtained by replacing the Newtonian space-time theater with the image of a presumably high-dimensional Hilbert space, through which

Reverse Inequalities for the Numerical Radius of Linear Operators in Hilbert Spaces
, 2005 Some elementary inequalities providing upper bounds for the difference of the norm and the numerical radius of a bounded linear operator on Hilbert spaces under appropriate conditions are ...
