Autor: Laure Thomarat, Frank Elson, Elisabetta Nocerino, Debarchan Das, Oleh Ivashko, Marek Bartkowiak, Martin Månsson, Yasmine Sassa, Tadashi Adachi, Martin v. Zimmermann, Hubertus Luetkens, Johan Chang, Marc Janoschek, Zurab Guguchia, Gediminas Simutis

Publikováno v: Communications Physics, Vol 7, Iss 1, Pp 1-7 (2024)

Abstract Strongly correlated electron materials are often characterized by competition and interplay of multiple quantum states. For example, in high-temperature cuprate superconductors unconventional superconductivity, spin- and charge-density wave

Two types of charge order with distinct interplay with superconductivity in the kagome material CsV3Sb5

Autor: Ritu Gupta, Debarchan Das, Charles Mielke, Ethan T. Ritz, Fabian Hotz, Qiangwei Yin, Zhijun Tu, Chunsheng Gong, Hechang Lei, Turan Birol, Rafael M. Fernandes, Zurab Guguchia, Hubertus Luetkens, Rustem Khasanov

Publikováno v: Communications Physics, Vol 5, Iss 1, Pp 1-8 (2022)

Kagome metals can house a complex interplay of competing phenomenon and there has been significant investigation into how to engineer the resultant properties, as well as understand the underlying physics. Here, the authors investigate the competitio

Unsplit superconducting and time reversal symmetry breaking transitions in Sr2RuO4 under hydrostatic pressure and disorder

Autor: Vadim Grinenko, Debarchan Das, Ritu Gupta, Bastian Zinkl, Naoki Kikugawa, Yoshiteru Maeno, Clifford W. Hicks, Hans-Henning Klauss, Manfred Sigrist, Rustem Khasanov

Publikováno v: Nature Communications, Vol 12, Iss 1, Pp 1-10 (2021)

Two possible scenarios of the superconducting order parameter in Sr2RuO4 remain difficult to distinguish. Here, the authors observe that the onset temperature of time reversal symmetry breaking tracks the superconducting transition temperature in Sr2

Superconducting Gap Structure of the Noncentrosymmetric Topological Superconductor Candidate HfRuP

Autor: Debarchan Das, Devashibhai Adroja, Rajesh Tripathi, Zurab Guguchia, Fabian Hotz, Hubertus Luetkens, Zhijun Wang, Dayu Yan, Huiqian Luo, Youguo Shi

Publikováno v: Magnetochemistry, Vol 9, Iss 5, p 135 (2023)

We investigate the gap symmetry of the topological superconductor candidate HfRuP, which crystallizes in a noncentrosymmetric hexagonal crystal structure, using muon spin rotation/relaxation (μSR) measurements in transverse-field (TF) geometry. The

μSR Study of Unconventional Pairing Symmetry in the Quasi-1D Na2Cr3As3 Superconductor

Autor: Amitava Bhattacharyya, Devashibhai Adroja, Yu Feng, Debarchan Das, Pabitra Kumar Biswas, Tanmoy Das, Jun Zhao

Publikováno v: Magnetochemistry, Vol 9, Iss 3, p 70 (2023)

We report the finding of a novel pairing state in a newly discovered superconductor Na2Cr3As3. This material has a non-centrosymmetric quasi-one-dimensional crystal structure and is superconducting at TC∼ 8.0 K. We find that the magnetic penetratio

Nodeless electron pairing in CsV3Sb5-derived kagome superconductors

Publikováno v: Nature. 617:488-492

The newly discovered kagome superconductors represent a promising platform for investigating the interplay between band topology, electronic order, and lattice geometry. Despite extensive research efforts on this system, the nature of the superconduc
