Diode effect in microwave irradiated Josephson junctions with Yu-Shiba-Rusinov states
Aritra Lahiri, Marcel Polák, Björn Trauzettel
We investigate the critical current in microwave-irradiated Josephson junctions hosting Yu-Shiba-Rusinov states due to magnetic impurities. Under two conditions, namely, (i) the br…
Signatures of superconducting Higgs mode in irradiated Josephson junctions
Aritra Lahiri, Juan Carlos Cuevas, Björn Trauzettel
The Higgs mode, originally proposed in the context of superconductivity, corresponds to oscillations of the amplitude of the superconducting order parameter. Recent THz-domain opti…
AC Josephson Signatures of the Superconducting Higgs Mode
Aritra Lahiri, Sang-Jun Choi, Björn Trauzettel
The Higgs mode in superconductors corresponds to oscillations of the amplitude of the order parameter. While its detection typically entails resonant optical excitation, we present…
AlzheimerRAG: Multimodal Retrieval Augmented Generation for Clinical Use Cases using PubMed articles
Aritra Kumar Lahiri, Qinmin Vivian Hu
Recent advancements in generative AI have fostered the development of highly adept Large Language Models (LLMs) that integrate diverse data types to empower decision-making. Among…
Origin of Subharmonic Gap Structure of DC Current-Biased Josephson Junctions
Aritra Lahiri, Sang-Jun Choi, Björn Trauzettel
The current-voltage characteristics of Josephson junctions exhibit a subharmonic gap structure (SGS), denoting jumps at specific voltages. While the prevalent multiple Andreev refl…
DragonVerseQA: Open-Domain Long-Form Context-Aware Question-Answering
Aritra Kumar Lahiri, Qinmin Vivian Hu
This paper proposes a novel approach to develop an open-domain and long-form Over-The-Top (OTT) Question-Answering (QA) dataset, DragonVerseQA, specifically oriented to the fantasy…
