Interferometric Readout of Momentum-Space Topology in a Programmable Dissipative Photonic Circuit
Andrea Cataldo, Emil J. Bergholtz, Daniel Leykam +2
Topology under non-Hermitian dynamics is encoded in the phase of the bulk evolution, yet strong dissipation suppresses the amplitudes carrying it. We resolve this using a programma…
Read-Rezayi fractional Chern insulators in modulated Bernal graphene
Ruth Mora-Soto, André Grossi Fonseca, Raul Perea-Causin +3
Fibonacci anyons provide a universal platform for topological quantum computation, and emerge as low-energy excitations in the Read-Rezayi phase in the fractional qu…
Quantum spin Hall crystals at fractional filling of twisted MoTe
Xiaoyang Shen, Raul Perea-Causin, Christopher Ekman +3
We predict and classify interaction-driven quantum spin Hall crystals (QSHCs), a class of states emerging at fractional filling through an interplay of topology and spontaneous tra…
Universal aspects of bulk density of states in non-Hermitian lattices
Mykhailo Pavliuk, Askar Iliasov, Emil J. Bergholtz +1
Non-Hermitian lattice Hamiltonians generally exhibit strong boundary sensitivity, with periodic and open boundary conditions producing distinct density of states (DOS) in the compl…
Nonreciprocal conductance in uniformly dissipative devices
Oliver Solow, Emil J. Bergholtz, Karsten Flensberg
When studying non-Hermitian electronic systems, an obvious question is how various non-Hermitian effects affect measurable quantities like the conductance. Here, we show that unifo…
Filling-Sensitive Spectral Complexity from Hilbert-Space Holonomy in Fragmented Non-Hermitian Systems
Jiong-Hao Wang, Maria Zelenayova, Christopher Ekman +1
We show that Hilbert-space holonomy provides a geometric organizing principle for spectral reality in fragmented non-Hermitian many-body systems, complementary to conventional symm…
