Functional Renormalization Group as a Ricci Flow: An \(\mathcal{F}\)-Entropy Perspective on Information Metric Dynamics
Jin Mo Bok, Ki-Seok Kim
We establish a geometric correspondence between the Functional Renormalization Group (FRG) and a Ricci flow modified by a potential-driven diffeomorphism. By rewriting the Polchins…
Finite-momentum inter-orbital superconductivity driven by chiral charge-density-wave quantum criticality beyond the BCS regime
Jin Mo Bok, B. J. Kim, Ki-Seok Kim
Superconductivity emerging near charge-density-wave (CDW) quantum critical points often defies a conventional BCS description, particularly in multi-orbital systems with small and…
Origin of chirality in transition-metal dichalcogenides
Kwangrae Kim, Hyun-Woo J. Kim, Seunghyeok Ha +15
Chirality is a ubiquitous phenomenon in which a symmetry between left- and right-handed objects is broken, examples in nature ranging from subatomic particles and molecules to livi…
Origin of the large differences in high-pressure stability and superconductivity between ThH9 and ThH18
Shichang Yao, Chongze Wang, Hyunsoo Jeon +5
Recently, the thorium hydride ThH9 possessing an H-rich clathrate structure has been experimentally synthesized to exhibit a superconducting transition temperature Tc of 146 K at 1…
phonon anomaly driven by Fermi surface instability at intermediate temperature in YBaCuO
Dongjin Oh, Dongjoon Song, Younsik Kim +5
We performed temperature- and doping-dependent high-resolution Raman spectroscopy experiments on YBaCuO to study phonons. The temperature dependence…
How to pin down the pairing interaction for high Tc superconductivity in cuprates
Han-Yong Choi, Jin Mo Bok
The normal and pairing self-energies are the microscopic quantities which reflect and characterize the underlying interaction in superconductors. The momentum and frequency depende…
Sharp low energy feature in single-particle spectra due to forward scattering in -wave cuprate superconductors
Seung Hwan Hong, Jin Mo Bok, Wentao Zhang +4
There is an enormous interest in renormalization of quasi-particle (qp) dispersion relation of cuprate superconductors both below and above the critical temperature because i…
Analysis of Laser ARPES from BiSrCaCuO in superconductive state: angle resolved self-energy and fluctuation spectrum
Jae Hyun Yun, Jin Mo Bok, Han-Yong Choi +3
We analyze the ultra high resolution laser angle resolved photo-emission spectroscopy (ARPES) intensity from the slightly underdoped BiSrCaCuO in the supercondu…
Momentum Dependence of the Single-Particle Self-Energy and Fluctuation Spectrum of Slightly Underdoped Bi_2 Sr_2 CaCu_2 O_{8+δ} from High Resolution Laser ARPES
Jin Mo Bok, Jae Hyun Yun, Han-Yong Choi +3
We deduce the normal state angle-resolved single-particle self-energy and the Eliashberg function (i.e., the product of the fluctuation spectrum and its coupling to fermi…
