Fluctuated spin-orbital texture of Rashba-split surface states in real and reciprocal space
Takuto Nakamura, Yoshiyuki Ohtsubo, Ayumi Harasawa +4
Spin-orbit interaction (SOI) in low-dimensional systems, namely Rashba systems and the edge states of topological materials, is extensively studied in this decade as a promising so…
Dark discrete breather modes in monoaxial chiral helimagnet with easy-plane anisotropy
I. G. Bostrem, E. G. Ekomasov, J. Kishine +2
Nonlinearity and discreteness are two pivotal factors for an emergence of discrete breather excitations in various media. We argue that these requirements are met in the forced fer…
Spin accumulation without spin current
Atsuo Shitade, Gen Tatara
The spin Hall (SH) effect is a phenomenon in which the spin current flows perpendicular to an applied electric field and causes the spin accumulation at the boundaries. However, in…
Ultrafast energy exchange between two single Rydberg atoms on the nanosecond timescale
Yeelai Chew, Takafumi Tomita, Tirumalasetty Panduranga Mahesh +3
Rydberg atoms, with their giant electronic orbitals, exhibit dipole-dipole interaction reaching the GHz range at a distance of a micron, making them a prominent contender for reali…
Silabenzene Incorporated Covalent Organic Frameworks
Kewei Sun, Orlando J. Silveira, Yujing Ma +6
Covalent organic frameworks (COFs) are a promising material for various applications such as gas storage/separation, catalysis, and energy storage, besides offering a confined spac…
Topological d-wave superconductivity in two dimensions
Youichi Yanase, Akito Daido, Kazuaki Takasan +1
Despite intensive searches for topological superconductors, the realization of topological superconductivity remains under debate. Previous proposals for the topological -wave,…
Chirality-Induced Spin Filtering in Pseudo Jahn-Teller Molecules
Akihito Kato, Hiroshi M. Yamamoto, Jun-ichiro Kishine
Chirality-induced spin selectivity (CISS) refers to an ability to induce a spin polarization of an electron transmitted through chiral materials. An important experimental observat…
Supercurrent-induced topological phase transitions
Kazuaki Takasan, Shuntaro Sumita, Youichi Yanase
We show that finite current in superconductors can induce topological phase transitions, as a result of the deformation of the quasiparticle spectrum by a finite center-of-mass (CO…
Truly chiral phonons in α-HgS
Kyosuke Ishito, Huiling Mao, Yusuke Kousaka +6
Chirality is a manifestation of the asymmetry inherent in nature. It has been defined as the symmetry breaking of the parity of static objects, and the definition was extended to d…
Unconventional Superconductivity in UTe2
D. Aoki, J. -P. Brison, J. Flouquet +4
The novel spin-triplet superconductor candidate UTe2 was discovered only recently at the end of 2018 and attracted enormous attention. We review key experimental and theoretical pr…
Nonreciprocal Meissner response in parity-mixed superconductors
Hikaru Watanabe, Akito Daido, Youichi Yanase
The parity breaking gives rise to rich superconducting properties through the admixture of even and odd-parity Cooper pairs. A new light has been shed on parity-breaking supercondu…
Nonreciprocal optical response in parity-breaking superconductors
Hikaru Watanabe, Akito Daido, Youichi Yanase
Superconductivity, an emergence of a macroscopic quantum state, gives rise to unique electromagnetic responses leading to perfect shielding of magnetic field and zero electrical re…
Superconducting piezoelectric effect
Michiya Chazono, Hikaru Watanabe, Youichi Yanase
The magnetopiezoelectric effect (MPE) is a cross-coupling between an electric current and strain in metals with neither inversion symmetry nor time-reversal symmetry. Unlike the co…
