Schrieffer-Wolff Transformation on IBM Quantum Computer
Rukhsan Ul Haq, Basit Iqbal, Mohsin Illahi +2
Schrieffer-Wolff transformation (SWT) has been extensively used in quantum many-body physics to calculate the low energy effective Hamiltonian. It provides a perturbative method to…
Study of Feature Importance for Quantum Machine Learning Models
Aaron Baughman, Kavitha Yogaraj, Raja Hebbar +3
Predictor importance is a crucial part of data preprocessing pipelines in classical and quantum machine learning (QML). This work presents the first study of its kind in which feat…
Large Scale Diverse Combinatorial Optimization: ESPN Fantasy Football Player Trades
Aaron Baughman, Daniel Bohm, Micah Forster +9
Even skilled fantasy football managers can be disappointed by their mid-season rosters as some players inevitably fall short of draft day expectations. Team managers can quickly di…
A systematic method for Schrieffer-Wolff transformation and its generalizations
Rukhsan Ul Haq, Keshav Singh
Schrieffer-Wolff transformation is extensively used in quantum many-body physics to calculate the low energy effective Hamiltonian. It offers a perturbative method to understand th…
An Explicit Method for Schrieffer-Wolff Transformation
Rukhsan Ul Haq, Sachin Satish Bharadwaj, Towseef Ali Wani
Schrieffer-Wolff transformation is a very important transformation in Quantum Many Body physics. Yet, there isn't an explicit method in the literature to calculate the generator of…
Schrieffer-Wolff transformation of Anderson Models
Rukhsan Ul Haq, Sachin Satish Bharadwaj
Schrieffer-Wolff transformation is one of the very important transformations in the study of quantum many body physics. It is used to arrive at the low energy effective hamiltonian…
Renormalization group study of quantum criticality in gapped Kondo model
Rukhsan Ul Haq, Anirban Sharma
Quantum impurity models are the prototypical examples of quantum many-body dynamics which manifests in their spectral and transport properties. Single channel Anderson(and Kondo mo…
Kondo Effect Route to Probing Majorana-Kramers Pairs Coupled to Quantum Dot
Rukhsan Ul Haq, Keshav Singh
In this paper, we study a set-up in which quantum dot is tunnel-coupled to Majorana-Kramers pair(MKP) which are the edge modes of time reversal invariant topological superconductor…
Scaling analysis of the extended single impurity Anderson model: Renormalization due to valence fluctuations
Rukhsan Ul Haq, N. S. Vidhyadhiraja
In this paper we have explored the role of valence fluctuations in an extended Anderson impurity model (e-SIAM) in which there is an additional Hubbard repulsion between conduction…
Quantum theory of time perception: phases,clocks and quantum algebra
Rukhsan Ul Haq, Shalini Harkar
Experience of time is one of the primordial human experiences which is deeply tied to human consciousness. But despite this intimate relation of time with human conscious experienc…
Iterants, Idempotents and Clifford algebra in Quantum Theory
Rukhsan Ul Haq, Louis H Kauffman
Projection operators are central to the algebraic formulation of quantum theory because both wavefunction and hermitian operators(observables) have spectral decomposition in terms…
Topological Order and Topological Protection of Majorana Fermion Qubits
Rukhsan Ul Haq, Louis H Kauffman
The Kitaev chain model exhibits topological order that manifests as topological degeneracy, Majorana edge modes and topological invariance of the abulk spectrum. This model…
The magic of universal quantum computing with permutations
Michel Planat, Rukhsan-Ul-Haq
The role of permutation gates for universal quantum computing is investigated. The \lq magic' of computation is clarified in the permutation gates, their eigenstates, the Wootters…
