Expansion for quantum perturbations in random spin systems
C. Itoi, K. Horie, H. Shimajiri +1
Energy eigenstates in the random transverse field Edwards-Anderson (EA) model and the random bond quantum Heisenberg XYZ model in a -dimensional finite cubic lattice are obtaine…
An Upper Limit of AC Huffman Code Length in JPEG Compression
Kenichi Horie
A strategy for computing upper code-length limits of AC Huffman codes for an 8x8 block in JPEG Baseline coding is developed. The method is based on a geometric interpretation of th…
Quantum Caustics for Systems with Quadratic Lagrangians in Multi-Dimensions
Kenichi Horie, Hitoshi Miyazaki, Izumi Tsutsui
We study quantum caustics in -dimensional systems with quadratic Lagrangians. Based on Schulman's procedure in the path-integral we derive the transition amplitude on caustics i…
Inequivalent Quantizations of Gauge Theories
Kenichi Horie
It is known that the quantization of a system defined on a topologically non-trivial configuration space is ambiguous in that many inequivalent quantum systems are possible. This i…
Geometric Interpretation of Electromagnetism in a Gravitational Theory with Torsion and Spinorial Matter
Kenichi Horie
Possible geometric frameworks for a unified theory of gravity and electromagnetism are investigated: General relativity is enlarged by allowing for an arbitrary complex linear conn…
New Insight into the Relation between Torsion and Electromagnetism
Kenichi Horie
In several unified field theories the torsion trace is set equal to the electromagnetic potential. Using fibre bundle techniques we show that this is no leading principle but a for…
