Ferroelectricity in a magnon Bose-Einstein condensate: Nonreciprocal superfluidity, exceptional points, and Majorana bosons

Kazuki Yamamoto, Takuto Kawakami, Mikito Koshino

We investigate a ferroelectric instability of a magnon Bose-Einstein condensate, mediated by its interaction with an electric field through a geometric Aharonov-Casher (AC) phase.…

Charge-localization-driven metal-insulator phase transition in layered molecular conductors

Savita Priya, Maxim Wenzel, Olga Iakutkina +7

The organic conductor $α$ -(BEDT-TTF) $_{2}$ I $_{3}$ provides the prime example of a charge-order-driven metal-insulator transition. Restricted chemical substitution of S atoms by Se in t…

Role of hydrogen bonding in charge-ordered organic conductor $α$ -(BEDT-TTF) $_{2}$ I $_{3}$ probed by $^{127}$ I nuclear quadrupole resonance

T. Kobayashi, Y. Kato, H. Taniguchi +3

We present $^{127}$ I nuclear quadrupole resonance spectra and nuclear relaxation of $α$ -(BEDT-TTF) $_{2}$ I $_{3}$ that undergoes a charge-ordering transition. Only one of the two I $_{3}$ a…

Change of superconducting character in UTe2induced by magnetic field

K. Kinjo, H. Fujibayashi, S. Kitagawa +13

UTe2 is a recently discovered spin-triplet superconductor. One of the characteristic features of UTe2 is a magnetic field (H)-boosted superconductivity above 16 T when H is applied…

Nodal-line semimetal HMTSF-TCNQ: Anomalous orbital diamagnetism and charge density wave

S. Ozaki, I. Tateishi, H. Matsuura +2

This study investigates the electronic states and physical quantities of an organic charge-transfer complex HMTSF-TCNQ, which undergoes a charge-density-wave (CDW) phase transition…

Stay with Your Community: Bridges between Clusters Trigger Expansion of COVID-19

Yukio Ohsawa, Masaharu Tsubokura

The spreading of virus infection is here simulated over artificial human networks. The real-space urban life of people is modeled as a modified scale-free network with constraints.…
