Topotaxial mutual-exchange growth of magnetic Zintl Eu3In2As4 axion insulator nanowires
The term "topotaxy" describes crystal growth process based on recrystallization in which the crystallographic orientation of the parent crystal determines that of the product composed crystal. Recently, a new method was developed and reported in the…
Fermi-Dirac Distribution Reformulated in Non-Hermitian Systems
Researchers have extended the traditional Fermi-Dirac distribution to non-Hermitian systems. This new formalism provides a general framework to compute quantum many-body observables in equilibrium systems coupled to dissipative environments.
Hydrodynamic properties of intrinsically disordered proteins
Intrinsically disordered proteins (IDPs), essential for regulating critical cellular functions, have long posed research challenges due to their lack of fixed three-dimensional structure. They are now more accessible for study thanks to a new model…
Quantum thermodynamics with a single superconducting vortex
We control and monitor the state of the single superconducting vortex. Using our fastest thermometer in the nanoworld, we measured the thermal transient due to the vortex expulsion from the superconductor. An energy dissipated due to this expulsion…
Pentagonal nanowires from topological crystalline insulators: a platform for intrinsic core-shell nanowires and higher-order band topology
We report on the first experimental realization of pentagonal nanowires within ionic compounds using Pb1-xSnxTe. The structures are potential candidates for realizing higher-order topology. The disclination and twin boundaries cause the states origi…
Unique electronic properties of gray tin
The seemingly ordinary and well-known material, tin, exhibits unique electronic properties under extreme but well controlled conditions. The discovery that it turns into Dirac and Weyl semimetals was made by an international team of researchers led…
A hybrid topological quantum state in elemental solid arsenic
An international team of scientists including dr Rajibul Islam from the Institute of Physics P.A.S. has demonstrated that the observed step-edge states in α-As, unlike surface or hinge states, are not expected for either first or higher-order topolo…
Signatures of a surface spin-orbital chiral metal
In an article published in the journal Nature, signatures of spin-orbital currents breaking both time-reversal and all crystalline symmetries were confirmed in an exotic surface chiral phase of Sr2RuO4. It was possible to find signatures of the soug…
