Author(s)
Zahra Ebrahim Nataj, Fariborz Kargar, Sergiy Krylyuk, Topojit Debnath, Maedeh Taheri, Subhajit Ghosh, Huairuo Zhang, Albert Davydov, Roger Lake, Alexander Balandin
We report the results of polarization-dependent Raman spectroscopy of phonon states in single-crystalline quasi-one-dimensional NbTe4 and TaTe4 van der Waals

Breakdown of Sound in Superfluid Helium

Author(s)
Marc Nichitiu, Craig Brown, Igor Zaliznyak
As elementary particles carry energy and momentum in the Universe, quasiparticles are the elementary carriers of energy and momentum quanta in condensed matter

Emergent Ferromagnetism in CaRuo3/CaMnO3 (111)-Oriented Superlattices

Author(s)
Margaret Kane, Churna Bhandari, Megan Holtz, Purnima Balakrishnan, Alexander Grutter, Michael R. Fitzsimmons, Chao-Yao Yang, Sashi Satpathy, Durga Paudyal, Yuri Suzuki
The boundary between CaRuO3 and CaMnO3 is an ideal test bed for emergent magnetic ground states stabilized through interfacial electron interactions. In this

Practical realisation of the kelvin by Johnson noise thermometry

A mode-locked laser photonic integrated circuit with a repetition rate of 10 GHz is optically synchronized to a tantalabased photonic crystal resonator comb

First-Order Phase Transition versus Spin-State Quantum-Critical Scenarios in Strain-Tuned Epitaxial Cobaltite Thin Films

Author(s)
John Dewey, Vipul Chaturvedi, Tatiana Webb, Prachi Sharma, William Postiglione, P. Quarterman, Purnima Balakrishnan, Brian Kirby, Lucca Figari, Caroline Korostynski, Andrew Jacobson, Turan Birol, Rafael Fernandes, Abhay Pasupathy, Chris Leighton
Pr-containing perovskite cobaltites exhibit unusual valence transitions, coupled to coincident structural, spin-state, and metal-insulator transitions

Digital PCR for the Characterization of Reference Materials

Author(s)
Megan Cleveland, Hua-Jun He, Mojca Milavec, Young-Kyung Bae, Peter Vallone, Jim Huggett
Well characterized reference materials are essential to ensuring the harmonization and accuracy of nucleic acid-based tests (such as qPCR); digital PCR (dPCR)
