Condensed Matter > Superconductivity

|
By Ka Ho, Genda Gu, Jack Zwettler
| arXiv
Superconductivity arises from Cooper pairing, but conventional photoemission probes electrons individually rather than as pairs. Here we report the observation of Cooper-pair emission from an optimally doped cuprate superconductor using two-electron angle-resolved photoemission (2e-ARPES).

Protostellar disks fed by dense collapsing gravo-magneto-sheetlets

|
By Ka Ho, Aramaki Aza-Aoba, Aoba-ku. Sendai
| Oxford University Press (OUP)
Stars form from the gravitational collapse of turbulent, magnetized molecular cloud cores. Our non-ideal MHD simulations reveal that the intrinsically anisotropic magnetic resistance to gravity during the core collapse naturally generates dense gravo-magneto-sheetlets within inner protostellar envelopes – disrupted versions of classical sheet-like pseudodisks.

Dynamics in Star-forming Cores (DiSCo): project overview and the first look towards the B1 and NGC 1333 regions in Perseus

|
By Ka Ho
| Oxford University Press (OUP)
The internal velocity structure within dense gaseous cores plays a crucial role in providing the initial conditions for star formation in molecular clouds. However, the kinematic properties of dense gas at core scales (∼0.01 − 0.1 pc) has not been extensively characterized because of instrument limitations until the unique capabilities of GBT-Argus became available.

Alterations in cellular metabolism under different grades of glioma staging identified based on a multi-omics analysis strategy

|
By Xianlei Yan, Qihang Yuan, Ka Ho, Yejun Tan
| Frontiers
1 Background Gliomas are the most common primary intracranial tumors that originate from brain glial cells (1). The grading system and classification criteria for brain gliomas are based on their histological features, cellular heterogeneity, and biological behavior. The 2021 WHO classification has taken a significant step in advancing the role of molecular diagnostics by incorporating critical diagnostic genes, molecules, pathways, and/or combinations into tumor classification (2).

Diagnosis of 3D magnetic field and modes composition in MHD turbulence with Y-parameter

|
By Deutsches Elektronen-Synchrotron DESY, Ka Ho, Los Alamos
| Oxford University Press (OUP)
Magnetic fields are crucial in numerous astrophysical processes within the interstellar medium. However, the detailed determination of magnetic field geometry is notoriously challenging. Based on the modern magnetohydrodynamic (MHD) turbulence theory, we introduce a novel statistical technique, the ‘Y-parameter’, to decipher the magnetic field inclination in the ISM and identify dominant turbulence modes.
