Nonequilibrium dynamics of doped Chern ferromagnets: a case study for false vacuum decay
Kilian Kuhlbrodt, Olivier Huber, Oliver Breach +7
Even though metastable false vacuum decay is ubiquitous in physics, its underlying dynamics are still not well understood. Dissipative state preparation in moiré quantum materials…
Observation of metastable chiral domain walls in a topological magnet
Richen Xiong, Chenxin Qin, Zhaoyu Han +17
The interplay between topology and correlation can give rise to exotic collective excitations. The integer and fractional quantum anomalous Hall (QAH) magnets recently discovered i…
Surface-Selective Probe of Spin-Triplet Superconductivity in Rhombohedral Graphene
Kilian Krötzsch, Kilian Krötzsch, Zekang Zhou +8
Superconductivity in rhombohedral graphene has been observed across many layer numbers, with mounting evidence pointing toward spin-triplet pairing, yet complementary probes of the…
Magnons reveal topology and dynamics of a skyrmion crystal
Raphael Ayache, Nilotpal Chakraborty, Manabendra Kuiri +11
Although individual skyrmions are topologically protected objects, their cooperative crystalline order is fragile, easily disrupted by thermal fluctuations or other external pertur…
Competing Orders Driven by Wigner Crystal Phase in Rhombohedral Graphene
Zekang Zhou, Kilian Krötzsch, Raphaël Ayache +7
The paper identifies a Wigner crystal phase in low‑density rhombohedral pentalayer graphene and shows how it gives rise to competing superconducting and reentrant quantum Hall stat…
Half state at = -1/2 and its transition in Decoupled Twisted Double Bilayer Graphene
Ning Ma, Kenji Watanabe, Takashi Taniguchi +1
The origin of the fractional state at = 1/2 observed in double-layer quantum Hall systems has been under debate for decades. Because of the variation of bilayer charge distrib…
