Why shot noise does not generally detect pairing in mesoscopic superconducting tunnel junctions

Autor: Niu, Jiasen, Bastiaans, Koen M., Ge, Jianfeng, Tomar, Ruchi, Jesudasan, John, Raychaudhuri, Pratap, Karrer, Max, Kleiner, Reinhold, Koelle, Dieter, Barbier, Arnaud, Driessen, Eduard F. C., Blanter, Yaroslav M., Allan, Milan P.

Publikováno v: Phys. Rev. Lett. 132, 076001 (2024)

The shot noise in tunneling experiments reflects the Poissonian nature of the tunneling process. The shot noise power is proportional to both the magnitude of the current and the effective charge of the carrier. Shot noise spectroscopy thus enables,

Publikováno v: Phys. Rev. B 108, L180503 (2023)

We report the formation of a pinned vortex liquid spanning a very large region of the magnetic field-temperature parameter space in a 5 nm thick amorphous superconducting Re_xZr (x~6) (a-ReZr) thin film, using a combination of low-temperature scannin

Signatures of Chiral Anomaly in the Magnetoresistance of a Quasi-3-Dimensional Electron Gas at the Interface of LaVO$_3$ and KTaO$_3$

Autor: Silotia, Harsha, Kumari, Anamika, Gupta, Anshu, De, Joydip, Pal, Santanu Kumar, Tomar, Ruchi, Chakraverty, S.

In a Dirac semimetal charges flow between two Weyl nodes when electric and magnetic fields (B||E) are parallel to each other manifesting interesting physical properties such as negative longitudinal magnetoresistance, planar Hall effect and anisotrop

Light-enhanced gating effect at the interface of oxide heterostructure

Autor: Wadehra, Neha, Tomar, Ruchi, Yokoyama, Yuichi, Yasui, Akira, Ikenaga, E., Wadati, H., Maryenko, Denis, Chakraverty, S.

In semiconducting materials, electrostatic gating and light illumination are widely used stimuli to tune the electronic properties of the system. Here, we show a significant enhancement of photoresponse at the conducting interface of LaVO3-SrTiO3 und

Planar Hall Effect and Anisotropic Magnetoresistance in a polar-polar interface of LaVO$_3$-KTaO$_3$ with strong spin-orbit coupling

Autor: Wadehra, Neha, Tomar, Ruchi, Gopal, R. K, Singh, Yogesh, Dattagupta, Sushanta, Chakraverty, S.

Among the perovskite oxide family, KTaO$_3$ (KTO) has recently attracted considerable interest as a possible system for the realization of the Rashba effect. In this work, we improvise a novel conducting interface by juxtaposing KTO with another insu

Observation of Shubnikov-de Haas Oscillations, Non-trivial Berry Phase, Planar Hall and Anisotropic Magnetoresistance at the conducting interface of EuO-KTaO$_3$

Autor: Kumar, Nand, Wadehra, Neha, Tomar, Ruchi, Dattagupta, Sushanta, Kumar, Sanjeev, Chakraverty, S.

The momentum dependent splitting of spin-bands in an electronic system is known as the "Rashba effect". Systems with the "Rashba effect" possess a Dirac point in momentum space. An electron in a cyclotron orbit enclosing that Dirac point in the recip
