Dissipation driven phase transition in the non-Hermitian Kondo model
Pradip Kattel, Abay Zhakenov, Parameshwar R. Pasnoori +2
Non-Hermitian Hamiltonians capture several aspects of open quantum systems, such as dissipation of energy and non-unitary evolution. An example is an optical lattice where the inel…
Complete Boundary Phase Diagram of the Spin- XXZ Chain with Boundary Fields in the Anti-Ferromagnetic Gapped Regime
Parameshwar R. Pasnoori, Yicheng Tang, Junhyun Lee +3
We consider the spin XXZ chain with diagonal boundary fields and solve it exactly using Bethe ansatz in the gapped anti-ferromagnetic regime and obtain the complete p…
Interplay between Symmetry Breaking and Interactions in a Symmetry Protected Topological Phase
Parameshwar R. Pasnoori, Patrick Azaria
We solve the one dimensional massive Thirring model or equivalently the sine-Gordon model in the repulsive regime with general Dirichlet boundary conditions, which are characterize…
Emergent boundary supersymmetry in a one dimensional superconductor
Parameshwar R. Pasnoori, Patrick Azaria, Colin Rylands +1
The interplay between bulk properties and boundary conditions in one-dimensional quantum systems, gives rise to many intriguing phenomena. These include the emergence of zero energ…
Duality symmetry, zero energy modes and boundary spectrum of the sine-Gordon/massive Thirring model
Parameshwar R. Pasnoori, Ari Mizel, Patrick Azaria
We solve the one-dimensional massive Thirring model, which is equivalent to the one-dimensional sine-Gordon model, with two types of Dirchlet boundary conditions: open boundary con…
Realizing a Symmetry Protected Topological Phase in a Superconducting Circuit
Parameshwar R. Pasnoori, Patrick Azaria, Ari Mizel
We propose a superconducting quantum circuit whose low-energy degrees of freedom are described by the sine-Gordon (SG) quantum field theory. For suitably chosen parameters, the cir…
