Decaf: A privacy preserving speech codec using speaker disentanglement and canonical voice conversion
Md Shakhrul Iman Siam, Dushyant Sharma, Stanislav Yu. Kruchinin +1
We present DECAF, a privacy preserving neural speech codec that obfuscates a speaker's voice while preserving linguistic content while maintaining automatic speech recognition (ASR…
Self-Consistent Spectral Quadrature Approach to Many-Body Green Functions
Stanislav Yu. Kruchinin
We develop a self-consistent spectral quadrature (sc-SQ) framework for the calculation of many-body Green functions. The method approximates the Källén--Lehmann spectral measure by…
XANE Background Acoustic Embeddings: Ablation and Clustering Analysis
Dushyant Sharma, James Fosburgh, Sri Harsha Dumpala +3
We explore the recently proposed explainable acoustic neural embedding~(XANE) system that models the background acoustics of a speech signal in a non-intrusive manner. The XANE emb…
XANE: eXplainable Acoustic Neural Embeddings
Sri Harsha Dumpala, Dushyant Sharma, Chandramouli Shama Sastri +3
We present a novel method for extracting neural embeddings that model the background acoustics of a speech signal. The extracted embeddings are used to estimate specific parameters…
Spatial Processing Front-End For Distant ASR Exploiting Self-Attention Channel Combinator
Dushyant Sharma, Rong Gong, James Fosburgh +3
We present a novel multi-channel front-end based on channel shortening with theWeighted Prediction Error (WPE) method followed by a fixed MVDR beamformer used in combination with a…
Excitons in mesoscopically reconstructed moiré heterostructures
Shen Zhao, Zhijie Li, Xin Huang +9
Moiré effects in twisted or lattice-incommensurate vertical assemblies of two-dimensional crystals give rise to a new class of quantum materials with rich transport and optical phe…
Moiré excitons in MoSe-WSe heterobilayers and heterotrilayers
Michael Förg, Anvar S. Baimuratov, Stanislav Yu. Kruchinin +7
Layered two-dimensional materials exhibit rich transport and optical phenomena in twisted or lattice-incommensurate heterostructures with spatial variations of interlayer hybridiza…
Exciton g-factors in monolayer and bilayer WSe from experiment and theory
J. Förste, N. V. Tepliakov, S. Yu. Kruchinin +7
The optical properties of monolayer and bilayer transition metal dichalcogenide semiconductors are governed by excitons in different spin and valley configurations, providing versa…
Giant Stokes shifts in AgInS nanocrystals with trapped charge carriers
Anvar S. Baimuratov, Irina V. Martynenko, Alexander V. Baranov +3
Nanocrystals of AgInS demonstrate giant Stokes shifts ~ 1 eV, the nature of which is still not clearly understood. We propose a theoretical model of this phenomenon bringing to…
Non-Markovian pure dephasing in a dielectric excited by a few-cycle laser pulse
S. Yu. Kruchinin
We develop the theory of pure dephasing in a solid exposed to an ultrashort laser pulse beyond the commonly used Markov approximation. This approach takes into account the finite c…
Strong-field Phenomena in Periodic Systems
Stanislav Yu. Kruchinin, Ferenc Krausz, Vladislav S. Yakovlev
The advent of visible-infrared laser pulses carrying a substantial fraction of their energy in a single field oscillation cycle has opened a new era in the experimental investigati…
Sub-cycle optical control of current in a semiconductor: from the multiphoton to the tunneling regime
Tim Paasch-Colberg, Stanislav Yu. Kruchinin, Özge Sağlam +10
Nonlinear interactions between ultrashort optical waveforms and solids can be used to induce and steer electric current on a femtosecond (fs) timescale, holding promise for electro…
Strong-Field Resonant Dynamics in Semiconductors
Michael S. Wismer, Stanislav Yu. Kruchinin, Marcelo Ciappina +2
We predict that a direct bandgap semiconductor (GaAs) resonantly excited by a strong ultrashort laser pulse exhibits a novel regime: kicked anharmonic Rabi oscillations (KARO). In…
