Direct Evidence of Unconventional Superconductivity in Doped Kagome system RVSb
Avior Almoalem, Yuqing Xing, Iksu Jang +7
The superconducting pairing symmetry of kagome metals remains a central unresolved question largely because phase-sensitive experiments capable of distinguishing between different…
Anomalous Hall viscosity of altermagnets
Iksu Jang, Rui Aquino, Jörg Schmalian +1
We show that the phonon Hall viscosity at zero magnetic field is a natural probe of altermagnetism. First, we demonstrate that the finite elements of the Hall viscosity tensor unam…
Elastic Quantum Criticality in Nematics and Altermagnets via the Elasto-Caloric Effect
Charles R. W. Steward, Grgur Palle, Markus Garst +2
The coupling between electronic nematic degrees of freedom and acoustic phonons is known to significantly alter the universality class of a nematic quantum critical point (QCP). Wh…
Prethermalization and transient dynamics of the Multi-Channel Kondo systems under generic quantum quenches: Insights form Large- Schwinger-Keldysh approach
Iksu Jang, Po-Yao Chang
Understanding out-of-equilibrium many-body quantum systems is crucial in contemporary physics. However, capturing the universal dynamics of such systems remains challenging despite…
Quantum phase transition from a paramagnetic Anderson insulating state to a ferromagnetic many-body localized state via an intermediate ferromagnetic metallic phase
Kyung-Yong Park, Iksu Jang, Ki-Seok Kim
Effects of electron correlations on Anderson insulators have been one of the central themes for recent two decades, suggesting that the Anderson insulating phase turns into a novel…
General properties of fidelity in non-Hermitian quantum systems with PT symmetry
Yi-Ting Tu, Iksu Jang, Po-Yao Chang +1
The fidelity susceptibility is a tool for studying quantum phase transitions in the Hermitian condensed matter systems. Recently, it has been generalized with the biorthogonal basi…
Effects of general non-magnetic quenched disorder on a spin-density-wave quantum critical metallic system in two spatial dimension
Iksu Jang, Ki-Seok Kim
We investigate the effects of general non-magnetic quenched disorder on a two-dimensional spin-density-wave (SDW) quantum critical metallic system and discuss how a clean SDW non-F…
Proximity-Effect-Induced Anisotropic Superconductivity in Monolayer Ni-Pb Binary Alloy
Yen-Hui Lin, Chia-Hsiu Hsu, Iksu Jang +7
Proximity effect facilitates the penetration of Cooper pairs that permits superconductivity in normal metal, offerring a promising approach to turn heterogeneous materials into sup…
Inhomogeneous Kondo destruction by RKKY correlations
Kyung-Yong Park, Iksu Jang, Ki-Seok Kim +1
The competition between the indirect exchange interaction (IEC) of magnetic impurities in metals and the Kondo effect gives rise to a rich quantum phase diagram, the Doniach Diagra…
Role of generic scale invariance in a Mott transition from a U(1) spin-liquid insulator to a Landau Fermi-liquid metal
Jinho Yang, Iksu Jang, Jae-Ho Han +1
We investigate the role of generic scale invariance in a Mott transition from a U(1) spin-liquid insulator to a Landau Fermi-liquid metal, where there exist massless degrees of fre…
Emergence of a Metal-Insulator Transition and High Temperature Charge Density Waves in VSe2 at the Monolayer Limit
Ganbat Duvjir, Byoung Ki Choi, Iksu Jang +13
Emergent phenomena driven by electronic reconstructions in oxide heterostructures have been intensively discussed. However, the role of these phenomena in shaping the electronic pr…
Universal renormalization group flow toward perfect Fermi-surface nesting driven by enhanced electron-electron correlations in monolayer vanadium diselenide
Iksu Jang, Ganbat Duvjir, Byoung Ki Choi +3
In the present study we examine nature of a charge ordering transition in monolayer vanadium diselenide (), which would be distinguished from that of bulk sample…
Chiral pair of Fermi arcs, anomaly cancelation, and spin or valley Hall effects in inversion symmetry-broken Weyl metals
Iksu Jang, Ki-Seok Kim
Anomaly cancelation has been shown to occur in time-reversal symmetry-broken Weyl metals, which explains the existence of a Fermi arc. We extend this result in the case of inversio…
Anomalous Hall effects beyond Berry magnetic fields in a Weyl metal phase
Iksu Jang, Jaeho Han, Ki-Seok Kim
Applying time-varying magnetic fields to Weyl metals, a pair of Weyl points become oscillating. This oscillating monopole and anti-monopole pair gives rise to AC Berry magnetic fie…
