Emergent Spacetime and Gravitational Nieh-Yan Anomaly in Chiral Weyl Superfluids and Superconductors

J Nissinen - Physical review letters, 2020‏ - APS
Momentum transport is anomalous in chiral p+ ip superfluids and superconductors in the
presence of textures and superflow. Using the gradient expansion of the semiclassical …

Lattice-fermionic Casimir effect and topological insulators

T Ishikawa, K Nakayama, K Suzuki - Physical Review Research, 2021‏ - APS
The Casimir effect arises from the zero-point energy of particles in momentum space
deformed by the existence of two parallel plates. For degrees of freedom on the lattice, its …

Lattice field theory with torsion

S Imaki, A Yamamoto - Physical Review D, 2019‏ - APS
Inspired by the duality between gravity and defects in crystals, we study lattice field theory
with torsion. The torsion is realized by a line defect of a lattice, namely, a dislocation. For the …

Non-Hermitian Hamiltonians are relevant to describe the features of a broad class of
physical phenomena, ranging from photonics and atomic and molecular systems to nuclear …

Tunable topological phases in quantum kirigamis

R Singh, A Agarwala - Physical Review B, 2025‏ - APS
Advances in engineering mesoscopic quantum devices have led to new material platforms

Symmetry breaking and lattice kirigami: Finite temperature effects

A Flachi, V Vitagliano - Physical Review D, 2019‏ - APS
Recent work has analyzed how deformations due to the insertion of a defect in a flat
hexagonal lattice affect the ground state structure of an interacting fermion field theory. Such …

-summed form of the QED effective action

J Navarro-Salas, S Pla - Physical Review D, 2021‏ - APS
We conjecture that the proper-time series expansion of the one-loop effective Lagrangian of
quantum electrodynamics can be summed in all terms containing the field-strength …

-summed form of adiabatic expansions in curved spacetime

A Ferreiro, J Navarro-Salas, S Pla - Physical Review D, 2020‏ - APS
The Feynman propagator in curved spacetime admits an asymptotic (Schwinger-DeWitt)
series expansion in derivatives of the metric. Remarkably, all terms in the series containing …

Landau levels in curved space realized in strained graphene

G Wagner, F de Juan, D Nguyen - SciPost Physics Core, 2022‏ - scipost.org
The quantum Hall effect in curved space has been the subject of many theoretical
investigations in the past, but devising a physical system to observe this effect is hard. Many …
