Prof. Ivan Dimov (BAS) and Prof. Alex Zaslavsky (Brown Univ.) will give lectures at IuE on May 24, 2022.

Prof. Ivan Dimov (BAS):
Efficient Quantum Monte Carlo Solutions on Supercomputers: How Close Are We to the Real Quantum Computer?
In order to determine how close we are to the "real quantum computer" the Wigner Monte Carlo method is considered. A short analysis of the convergence of the Signed Particle Formulation of Quantum Mechanics will be given. Extensive numerical experiments with Monte Carlo, quasi-Monte Carlo (QMC), and scrambled quasi-Monte Carlo algorithms based on Sobol sequences will be presented to support the theoretical studies. Main conclusions will be drawn from numerical tests which were executed on massively parallel supercomputers and some exciting results will be presented. In addition, recent developments of PetaSC supercomputers will be given with a focus on the Discoverer supercomputer.

This lecture is sponsored by our Christian Doppler Laboratory for High Performance TCAD.

Prof. Alex Zaslavsky (Brown Univ.):
CMOS+X: Hybrid Integration of Sensors with CMOS from Ambient to Cryogenic Temperatures
While silicon technology is poised to dominated digital computation for the foreseeable future, the integration of many types of non-Si-based sensors, detectors and devices is an open field.  This talk will describe some attempts at CMOS-compatible add-on devices.  Visible to near-infrared Ge quantum-dot based photodetectors with high internal gain and state-of-the-art responsivity will be presented. Then, a pseudo-nonvolatile single-transistor CMOS compact memory operating at cryogenic temperatures will be presented, discovered while working on magnetic tunnel-junction-based field sensors.  Time permitting, the talk will conclude with amorphous-oxide-based thin-film transistors with near-perfect subthreshold slope, 107 on/off current ratio, and arbitrary substrate compatibility.
