Entanglement entropy scaling transition under competing monitoring protocols
Mathias Van Regemortel, Ze-Pei Cian, Alireza Seif +2
Dissipation generally leads to the decoherence of a quantum state. In contrast, numerous recent proposals have illustrated that dissipation can also be tailored to stabilize many-b…
Optically induced topological superconductivity via Floquet interaction engineering
Hossein Dehghani, Mohammad Hafezi, Pouyan Ghaemi
We propose a mechanism for light-induced unconventional superconductivity in a two-valley semiconductor with a massive Dirac type band structure. The superconducting phase results…
Extraction of many-body Chern number from a single wave function
Hossein Dehghani, Ze-Pei Cian, Mohammad Hafezi +1
The quantized Hall conductivity of integer and fractional quantum Hall (IQH and FQH) states is directly related to a topological invariant, the many-body Chern number. The conventi…
Many-body Chern number from statistical correlations of randomized measurements
Ze-Pei Cian, Hossein Dehghani, Andreas Elben +5
One of the main topological invariants that characterizes several topologically-ordered phases is the many-body Chern number (MBCN). Paradigmatic examples include several fractiona…
Optical imprinting of superlattices in two-dimensional materials
Hwanmun Kim, Hossein Dehghani, Hideo Aoki +2
We propose an optical method of shining circularly polarized and spatially periodic laser fields to imprint superlattice structures in two-dimensional electronic systems. By changi…
Optical Enhancement of Superconductivity via Targeted Destruction of Charge Density Waves
Hossein Dehghani, Zachary M. Raines, Victor M. Galitski +1
It has been experimentally established that the occurrence of charge density waves is a common feature of various under-doped cuprate superconducting compounds. The observed states…
