Gauge-potential formulation of heat
We first investigated the gauge-potential formulation of the heat-transport model and demonstrated the role of scalar and vector heat potentials. We then show the analogy gauge and field potentials compared with…

Reversible control over the distribution of chemical inhomogeneities in multiferroic BiFeO3
We grew epitaxially strained (001)p.c.-oriented La0.15Bi0.85FeO3 films with a thickness of 100 nm on a 14-nm-thick SrRuO3 buffer layer on top of (110)o-oriented single-crystalline DyScO3 substrates using pulsed laser deposition. Here, we chose…

Topological links and knots of speckled light mediated by coherence singularities
Within a coherent light field, a point exhibiting zero intensity and an indeterminate phase is referred to as a phase singularity. In the context of the polarization dimension, a point characterized by an undefined polarization vector is referred…

Probabilistic alignment of multiple networks
Probabilistic formulation of the problem of aligning multiple networks
Consider K network observations, with N nodes each and adjacency matrices {Ak; , k = 1, …, K }. We consider networks that are directed and with binary edges (that…

Defying 60 Years of Physics – “Strange Metals” Break the Rules of Electricity
Strange metals challenge the 60-year-old theory that electric current consists of a flow of discrete charges. Strange metals show electricity carried by a quantum fluid rather than discrete electrons, challenging the long-standing Fermi liquid…

Gapless dispersive continuum in a modulated quantum kagome antiferromagnet
Growth of Cs8RbK3Ti12F48 single crystals and crystal structure determination
Single crystals of Cs8RbK3Ti12F48 were grown using alkali metal chlorides as flux. For starting materials, alkali metal fluorides and chlorides were dried, and TiF3 was…
