A method is proposed to solve a longstanding problem in photoelectron spectroscopy: the determination of the branching ratio between intrinsic and extrinsic plasmon generation. Attosecond metrology in combination with model simulations allow for a disentanglement of these excitation channels providing novel insight into the many-electron response of metals.

In quantum mechanics, weak measurement allows one to measure off diagonal matrix elements of operators. In this work, the author designs a weak value protocol which can be harnessed to measure the topological invariant of a quantum spin Hall insulator.

Much attention has been devoted recently to identify possible ways to overcome the notorious sign problem encountered in quantum Monte Carlo simulations. The authors of this paper propose a new method based on Majorana representation of complex fermions, which they dub Majorana Quantum Monte Carlo (MQMC). They find a class of SU(N) fermionic models which are sign-free in MQMC but cannot be solved with other available methods.

Nonsymmorphic materials, which possess special symmetry operations (screw rotation, glide mirror), have been theoretically reexamined in recent years for possible novel quantum phases or electronic functions derived from the symmetry requirements. Here, the authors demonstrate that in the typical nonsymmorphic material IrO, the type of charge carrier (electron or hole) is strongly dependent on the crystal orientation and capable of being switched by a magnetic field. This remarkable effect is seen in electrical transport measurements on various thin films supported by simple tight-binding and band structure calculations.
