Rice University researchers have demonstrated that isotopically enriched boron arsenide crystals can sustain quantum ...

Chirality is the breaking of reflection and inversion symmetries. Simply put, it is when an object’s mirror images cannot be superimposed over each other. A common example are your two hands—while ...

Physicists in China have uncovered new evidence that chiral phonons and magnons can interact strongly inside magnetic crystals. Using neutron spectroscopy, a team led by Song Bao at Nanjing University ...

A new study published in Nature Physics introduces a theory of electron-phonon coupling that is affected by the quantum geometry of the electronic wavefunctions. The movement of electrons in a lattice ...

A collaborated team led by Prof. SU Fuhai from Hefei Institutes of Physical Science (HFIPS), Chinese Academy of Sciences (CAS), together with researchers from Aerospace Information Research Institute, ...

A team has developed a new measurement method that, for the first time, accurately detects tiny temperature differences in the range of 100 microkelvin in the thermal Hall effect. Previously, these ...

New measurements in germanium reveal how excited electrons drive lattice vibrations that govern energy flow and heating in semiconductors. (Nanowerk News) Whether in a smartphone or laptop, ...

A condition long considered to be unfavorable to electrical conduction in semiconductor materials may actually be beneficial in 2D semiconductors, according to new findings by UC Santa Barbara ...

Chirality can be true or false, depending on the symmetry of dynamic propagation. Crystal lattice vibrations, called phonons, can also display chirality as has been shown in some two-dimensional ...
